I am using Aspose.Words to do the MailMerge. But after merge for a merge field, It is showing Error! Unknown op code for conditional in document itself. This error may be due to incorrectly formed merged field. But my requirement is to detect/catch such error through code. Because, in our case user themselves creates the word template and upload into system. I have written very simple code to read do the mail merge.
doc.MailMerge.Execute(this.DataSource.Rows[rowIndex];
Can we detect such error in code? I tried to find online, but nothing useful could find.
No exception will be thrown in this scenario, but you can catch using the result of field after merging. Try the below sample code
// Load the document
Aspose.Words.Document doc = new Aspose.Words.Document(src);
// Do processing and mail merge etc
// Select all field start nodes so we can find the merge fields.
NodeCollection fieldStarts = doc.GetChildNodes(NodeType.FieldStart, true);
foreach (FieldStart fieldStart in fieldStarts)
{
// Get the next sibling
Run fieldResult = (Run)fieldStart.NextSibling;
// Match the error code with the result
if (fieldResult.NextSibling.NextSibling.GetText().Equals("Error! Unknown op code for conditional.", StringComparison.CurrentCultureIgnoreCase))
{
// Find the page number, where the field is present
LayoutCollector collector = new LayoutCollector(doc);
int pageNumber = collector.GetStartPageIndex(fieldStart);
Console.WriteLine("Error in field at Page: " + pageNumber + ". Field text: " + fieldResult.GetText());
}
}

I created PowerBI report which which is connecting to data source via API service. Returning json contains thousands of entities. API service is called via Web.Content function. API service returns always total record count and so we are able to calculate nr. of pages which has to be called to obtain whole dataset. This report is displaying data from our servicedesk app, which is deployed on many servers and for many customers and use Query parameters to connect to any of these servers.
Detail of Power query is below.
Why am I writing here. This report was working without any issue more than 1,5 year but on August 17th one of servers start causing erros in step Pages where are some random lines (pages) with errors - see attached picture labeled "Errors in step Pages". and this is reason that next step Entities (List.Union) in query is stopping refresh and generate errors with message:
Expression.Error: We cannot apply field access to the type List. Details: Value=[List] Key=requests
What is notable
API service si returning records in the same order but faulty lists are random when calling with same parameters
some times is refresh without any error
The same power query called on another server is working correctly , problem is only with one specific server.
This problem started without notice on the most important server after 1,5 year without any problem.
Here is full text power of query for this main source, which is used later in other queries to extract all necessary data. Json is really complicated and I extract from it list of requests, list of solvers, list of solver groups,.... and this base query and its output is input for many referenced queries.
Errors in step Pages
let
BaseAPIUrl = apiurl&"apiservice?", /*apiurl is parameter - name of server e.g. https://xxxx.xxxxxx.sk/ */
EntitiesPerPage = RecordsPerPage, /*RecordsPerPage is parameter and defines nr. of record per page - we used as optimum 200-400 record per pages, but is working also with 4000 record per page*/
ApiToken = FnApiToken(), /*this function is returning apitoken value which is returning value of another api service apiurl&"api/auth/login", which use username and password in body of call to get apitoken */
GetJson = (QParm) => /*definiton general function to get data from data source*/
let
Options =
[ Query= QParm,
Headers=
[
Accept="application/json",
ApiKeyName="apitoken",
Authorization=ApiToken
]
],
RawData = Web.Contents(BaseAPIUrl, Options),
Json = Json.Document(RawData)
in Json,
GetEntityCount = () => /*one times called function to get nr of records using GetJson, which is returned as a part of each call*/
let
QParm = [pp="1", pg="1" ],
Json = GetJson(QParm),
Count = Json[totalRecord]
in
Count,
GetPage = (Index) => /*repeatadly called function to get each page of json using GetJson*/
let
PageNr = Text.From(Index+1),
PerPage = Text.From(EntitiesPerPage),
QParm = [pg = PageNr, pp=PerPage],
Json = GetJson(QParm),
Value = Json[data][requests]
in Value,
EntityCount = List.Max({ EntitiesPerPage, GetEntityCount() }), /*setup of nr. of records to variable*/
PageCount = Number.RoundUp(EntityCount / EntitiesPerPage), /*setup of nr. of pages */
PageIndices = { 0 .. PageCount - 1 },
Pages = List.Transform(PageIndices, each GetPage(_) /*Function.InvokeAfter(()=>GetPage(_),#duration(0,0,0,1))*/), /*here we call for each page GetJson function to get whole dataset - there is in comment test with delay between getpages but was not neccessary*/
Entities = List.Union(Pages),
Table = Table.FromList(Entities, Splitter.SplitByNothing(), null, null, ExtraValues.Error)
I also tried another way of appending pages to list using List.Generate. This is also bringing random errors in list but
it is bringing possibility to transform to table in contrast with original way with using List.Transform, but other referenced queries are failing and contains on the last row errors
When I am exploring content of faulty page/list extracting it via Add as New Query there are always all record without any fail.....
Source = List.Generate( /*another way to generate list of all pages*/
() => [Page = 0, ReqPageData = GetPage(0) ],
each [Page] < PageCount,
each [ReqPageData = GetPage( [Page] ),
Page = [Page] + 1 ],
each [ReqPageData]
),
#"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error), /*here i am able to generate table from list in contrast when is used List.Generate*/
#"Expanded Column1" = Table.ExpandListColumn(#"Converted to Table", "Column1"), /*here aj can expand list to column*/
#"Removed Errors" = Table.RemoveRowsWithErrors(#"Expanded Column1", {"Column1"}) /*here i try to exclude errors, but i dont know what happend and which records (if any) are excluded*/
Extracting errored page
and finnaly I am tottaly clueless not able to find the cause of this behavior on this specific server. I tested to call pages which are errored via POSTMAN, I discused this issue with author of API service and He also tried to call this API service with all parameters but server is returning every page OK, only Power query is not able to List.Transform ...
I will be grateful and appreciate any tips or advice or if somebody solved the same issue in the past ....
Kuby
No, each error line of list in step List.Transform coud by extracted as new query and there are all records from one page OK. hmmmm
Finnaly, problem described in this issue was caused by "corrupted" content of returning json. The provider of core system informed me that they found bug and after fixing on the side of servisdesk is everything OK again. I tried to find problem in Power query and problem was in servisdesk. :(
I'm trying to embed a Zoho CRM by iframe into an application that knows only a phone number.
(Ramble: Originally I intended to call the Zoho api to lookup the Contact by phone number and redirect to or load the Contact's Zoho page - but the hosting app doesn't seem to support enough features to accommodate Zoho's OAuth2-only authentication - so I think I'm stuck with Zoho Deluge which I'm finding to be an ATROCIOUS language)
I'm hoping to GET navigate to this Zoho Function with the phone number as a parameter, have it find the unique match, and redirect to the customer details.
response = zoho.crm.searchRecords(
"Contacts",
"", // no criteria - I hope the later parameter
// normalizes better than this would?
1, // first page
2, // of two max results - just to verify uniqueness
"{ phone: '" + phoneNumber + "'}"); // Docs are terrible. Is this the format?
// I also tried "phone:equal:..."
//if (1 < response.size()) { // script errors show up on nonsense line
// return "[Ambiguous]"; // numbers, but this seems to work until later
//} // lines are included - then errors point here
return response; // Works, but useless string output
return response.firstName; // "Invalid collection object found" - but not expected to work
return response.get(0); // 'TEXT' can not be cast to '[KEY-VALUE, TEXT, LIST]' for the function 'get'
return response.get('firstName'); // 'TEXT' can not be cast to '[KEY-VALUE, TEXT, LIST]' for the function 'get'
return response.get(0).firstName; // Improper Statement Error might be due to missing ';' at end of the line or incomplete expression
// openUrl( <string>, <window_type> ); // hoping to get here
I've also tried variations on returning from inside a for each element loop, no luck.
I THINK I've successfully found the user by phone number because I think I indeed get one match, but I can't verify it and I don't know how to derive the url of the customer detail page for the openUrl() call. Do you know how to make progress on this?
The criteria is malformed, and function searchRecords returns a list of maps.
To access the first element of al list you must use .get(0) and get an element of a map .get("First_Name")
The fields are malformed, you must get the API name of the field form crm.zoho.com->setup->API->API names->Contacts
You can use info to debug the response (info response;)
Zoho CRM API Search records
toReturn = "";
response = zoho.crm.searchRecords("Contacts", "Phone:equals:" + phoneNumber, 1, 2);
if (1 < response.size()) {
toReturn = "[Ambiguous]";
} else if (0 == response.size()) {//error triggered if use get(0) of emty list
toReturn = "[None]";
}else {
toReturn = reponse.get(0).get("First_Name");
openUrl("https://crm.zoho.com/crm/org[yourOrgID]/tab/Contacts/" + reponse.get(0).get("id"), "new window");
}
return toReturn;
i'm just starting out with Dexie, and I seem to be coming unstuck.
I have a small database (less than 1000 rows), and i'm trying to delete each row one-by-one once I know that the row has been sent to a remote API.
I can also successfully save to the table (which is defined by an ID and a column storing a serialised object)
here's my code:
if (online) {
//we query the db and send each event
database.open()
let allEvents = database.events.toCollection()
let total = allEvents.count(function (count) {
console.log(count + ' events in total')
//a simple test to ensure we're seeing the right number of records
})
allEvents.each(function(thisEvent){
//push to remote API
console.log('deleting ' + thisEvent.id)
database.events.delete(thisEvent.id) //<= this doesn't seem to be working
})
}
All of this with the exception of the final delete statement.
Any ideas on how I should fix this? the important thing for me is to delete on a per-row basis.
thanks in advance!
I was experiencing the same problem, and the answer from Eugenia Pais wasn't working for me. So after some tests, I saw the trouble was with the type of the variable: I was using a string, but a number is needed, so this is how I solved it:
function removeRow (primaryKey) {
primaryKey = parseInt(primaryKey);
databaseName.tableName.where('primaryKey').equals(primaryKey).delete().then(function(deleteCount) {
console.log ("Deleted " + deleteCount + " rows");
}).catch(function(error) {
console.error ("Error: " + error);
});
So be aware you are using a number as argument.
The correct way to delete each row should be selecting the specific row and delete it:
database.tableName.where(indexId).equals(indexValue).delete();
The data type of the key is not a problem you could verify it in my example here: example
db.example.where('key').equals('one').delete();
Maybe you are trying to delete by a property that not is an index.
This has me stumped and I'm pulling my hair out here.
The simple query below finds speeches for the current user:
var _debug = function(cb) {
console.log('_debug')
var DebugParseObject = Parse.Object.extend("Speech");
var debugQuery = new Parse.Query(DebugParseObject);
debugQuery.equalTo("user", _getCurrentUser()); // Incorrect results only occurs when I set the user with this line
debugQuery.find({
success: function(results) {
console.log("Successfully retrieved " + results.length + " scores.");
cb(results);
},
error: function(error) {
console.log("Error: " + error.code + " " + error.message);
}
});
};
The speech object class has the following extra columns
title
body
speech_id
user (pointer)
Here is the weird part: The query will only return the speeches whose body is a string less than about 1000 characters.
As in, I can have Speech A, with a 500 character string in the body field. It will be returned as one of the speeches. BUT if I increase Speech A's body string to about 1500 characters, it will NOT be returned any longer.
I can't understand why.
Some further points
It's only when I filter by the user. If I search for all speeches or query by a different parameter (e.g. title), then the correct amount is returned
This used to work fine yesterday and before
I manually deleted a user earlier (removed the row from the table), while their linked speeches still existed
I changed those speeches' users value from the deleted user id to a new users id
The speeches appear to have the correct user
I tried re-saving the user object on the speech's user property and it didn't do anything
Any help will be great! I feel like I've corrupted the user class when I deleted the user row. But I can't prove it.
The query syntax looks solid and you should be well within the storage limitations of Parse. In case you're curious, there's no explicit limit on string length, but Parse Objects are limited to 128k (except for Parse Files of course).
My guess is that something has gone awry when copying over a different user in place of the one you deleted. Manually changing data and pointers within the browser is always risky and prone to errors.
I'm working on my Excel exporting using Apache POI. I want to be able to include a query string to limit the exported contents, but I either end up getting 0 documents or getting a couple of documents.
When I get a couple of document, it's unclear if the view object is actually modified. It still responds to getEntryCount with 13 documents, but exports just 2 and doesn't print the columnValues for those two. If I don't use the search, it exports the entire view flawlessly.
The server-side javascript has these few relevant lines.
function createWorkbookStreamWithLabels(workbookName,sheetName,fieldList,dbName,viewName,colLabels,totalLabels,queryString){
...a bunch of other code to get a handle to the view...
postValidationError(control,"Entries: " + view.getEntryCount());
var docCount = view.FTSearchSorted(queryString);
postValidationError(control,"Query: " + queryString);
postValidationError(control,"Query count: " + docCount);
if ( docCount == 0) return;
...code that walks the view and prints the contents...
}
My 0 hit queries include:
FIELD lastname CONTAINS e
and
[state] CONTAINS V
The one that gets two hits is simple:
VA
The view is sorted and now the database is full-text indexed. The column containing State is now sorted and click to sort, ascending.
Just for reference, here's the function that displays my status messages.
function postValidationError(control, msg) {
if ((typeof msg) != "string")
return;
var msgObj = new javax.faces.application.FacesMessage(javax.faces.application.FacesMessage.SEVERITY_ERROR, msg, msg);
facesContext.addMessage(control.getClientId(facesContext), msgObj);
control.setValid(false);
}
What have I done wrong?
Update: the problem with my search queries is solved, but my code also seems to have a terrific tendency to crash HTTP or the server.
