In the Expression Builder for the Workplace Process Designer, I have an attachment variable of type String[] (array of strings). I'd like to add some elements to it using the Expression Builder, but I can't work out the syntax. Has anyone done this? Is it even possible to add elements to an existing array in Expression Builder?
The arraytostring solution only works if there is only one element the array.
Assign the additional value with the following expression:
stringarray[elementcount(stringarray) + 1] = value
The expected 'array out of bound exception' and the resizing of the array is handled during the assignment.
I originally thought that it is not possible that we had to resort to have a custom java component to do the job, however I had run a small experiment that should serve as a workaround for your case.
Suppose you have String[] arrayType={"string1, string2"}, you can use the following expression as a value for your updated array:
{(arraytostring(arrayType, " ", " ,", ","))+"string3"}
What I did was that,
First, I used arraytostring function to convert the array to a string separated by comma with a comma left at the end. My output is similar to string1,string2,
Second, I appended the string that I want to add to the end of the string, so that my output is string1,string2,string3
Lastly, I assigned the value above to my array, using the array expression format {}, so my final evaluated string is {string1,string2,string3}
For more information about array functions, please follow the link below:
https://www.ibm.com/support/knowledgecenter/SSNW2F_5.2.1/com.ibm.p8.pe.user.doc/bpfe003.htm
I had a case like this, here is what I did:
I get the array from the attachment using the CE-Operation and store
in an array property on the workflow
Then I used the following to
{(arraytostring(workflowArray, " ", " ,", ","))+workflowStringProp}
using the CE-Operation again to set the array in the attachment with
the workflowArray.

I've seen the JSON array questions here and I'm still a little lost, so could use some extra help.
Here's the setup:
My Flow calls a sproc on my DB and that sproc returns this JSON:
{
"ResultSets": {
"Table1": [
{
"OrderID": 9518338,
"BasketID": 9518338,
"RefID": 65178176,
"SiteConfigID": 237
}
]
},
"OutputParameters": {}
}
Then I use a PARSE JSON action to get what looks like the same result, but now I'm told it's parsed and I can call variables.
Issue is when I try to call just, say, SiteConfigID, I get "The output you selected is inside a collection and needs to be looped over to be accessed. This action cannot be inside a foreach."
After some research, I know what's going on here. Table1 is an Array, and I need to tell PowerAutomate to just grab the first record of that array so it knows it's working with just a record instead of a full array. Fair enough. So I spin up a "Return Values to Virtual Power Agents" action just to see my output. I know I'm supposed to use a 'first' expression or a 'get [0] from array expression here, but I can't seem to make them work. Below are what I've tried and the errors I get:
Tried:
first(body('Parse-Sproc')?['Table1/SiteConfigID'])
Got: InvalidTemplate. Unable to process template language expressions in action 'Return_value(s)_to_Power_Virtual_Agents' inputs at line '0' and column '0': 'The template language function 'first' expects its parameter be an array or a string. The provided value is of type 'Null'. Please see https://aka.ms/logicexpressions#first for usage details.'.
Also Tried:
body('Parse-Sproc')?['Table1/SiteconfigID']
which just returns a null valued variable
Finally I tried
outputs('Parse-Sproc')?['Table1']?['value'][0]?['SiteConfigID']
Which STILL gives me a null-valued variable. It's the worst.
In that last expression, I also switched the variable type in the return to pva action to a string instead of a number, no dice.
Also, changed 'outputs' in that expression for 'body' .. also no dice
Here is a screenie of the setup:
To be clear: the end result i'm looking for is for the system to just return "SiteConfigID" as a string or an int so that I can pipe that into a virtual agent.
I believe this is what you need as an expression ...
body('Parse-Sproc')?['ResultSets']['Table1'][0]?['SiteConfigID']
You can see I'm just traversing down to the object and through the array to get the value.
Naturally, I don't have your exact flow but if I use your JSON and load it up into Parse JSON step to get the schema, I am able to get the result. I do get a different schema to you though so will be interesting to see if it directly translates.
I have an xml
<family>
<child_one>ROY</child_one>
<child_two>VIC</child_two>
</family>
I want to fetch the value from the XML based on the dynamic tag in ESQL. I have tried like this
SET dynamicTag = 'child_'||num;
SET value = InputRoot.XMLNSC.parent.(XML.Element)dynamicTag;
Here num is the value received from the input it can be one or two. The result should be value = ROY if num is one and value is VIC if num is two.
The chapter ESQL field reference overview describes this use case:
Because the names of the fields appear in the ESQL program, they must be known when the program is written. This limitation can be avoided by using the alternative syntax that uses braces ( { ... } ).
So can change your code like this:
SET value = InputRoot.XMLNSC.parent.(XMLNSC.Element){dynamicTag};
Notice the change of the element type as well, see comment of #kimbert.
Attempting to confirm that of all the schema in the head of a page exactly 3 of them should have a specific string within them. These schemas have no tags or sub classes to differentiate themselves from each other, only the text within them. I can confirm that the text exists within any of the schema:
cy.get('head > script[type="application/ld+json"]').should('contain', '"#type":"Product"')
But what I need is to confirm that that string exists 3 times, something like this:
cy.get('head > script[type="application/ld+json"]').contains('"#type":"Product"').should('have.length', 3)
And I can't seem to find a way to get this to work since .filter, .find, .contains, etc don't filter down the way I need them to. Any suggestions? At this point it seems like I either need to import a custom library or get someone to add ids to these specific schema. Thanks!
The first thing to note is that .contains() always yields a single result, even when many element match.
It's not very explicit in the docs, but this is what it says
Yields
.contains() yields the new DOM element it found.
If you run
cy.get('head > script[type="application/ld+json"]')
.contains('"#type":"Product"')
.then(console.log) // logs an object with length: 1
and open up the object logged in devtools you'll see length: 1, but if you remove the .contains('"#type":"Product"') the log will show a higher length.
You can avoid this by using the jQuery :contains() selector
cy.get('script[type="application/ld+json"]:contains("#type\": \"Product")')
.then(console.log) // logs an object with length: 3
.should('have.length', 3);
Note the inner parts of the search string have escape chars (\) for quote marks that are part of the search string.
If you want to avoid escape chars, use a bit of javascript inside a .then() to filter
cy.get('script[type="application/ld+json"]')
.then($els => $els.filter((index, el) => el.innerText.includes('"#type": "Product"')) )
.then(console.log) // logs an object with length: 3
.should('have.length', 3);
I know they advice to get a cell value this way:
columnValue = vars.getObject("resultObject").get(0).get("Column Name");
as stated on jMeter doc : component reference : JDBC_Request.
But: How to access the same RS cell value by just a number of the column?
RS.get(0).get(4);
...instead of giving it a String of column Name/Label.
edit 1: Lets use Groovy/Java, instead of BeanShell. Thanks.
edit 2: The original motivation was the difference between column Name / Label, as these seem to be not fully guaranteed (? seems to be not clear here, not to me), especially due case-sensitivity ("id"/"ID", "name"/"Name"/"NAME" ..)
It should be something like:
String value = (new ArrayList<String>(vars.getObject("resultObject").get(0).values())).get(4)

Be aware that according to HashMap documentation:
This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time.
So the order of columns might be a big question mark.
The row itself is a HashMap, defined in source code as:
HashMap<String, Object> row
So using BeanShell syntax, you could get it as
row = vars.getObject("resultObject").get(0); // returns HashMap
In HashMap, you cannot access item (column) by ID. You could, however, apply one of the methods described here, but HashMap doesn't guarantee order, so you cannot be sure what "column 4" will contain.
If you want to be able to loop through all columns, it's better to do it in a Map style, not by index. For example using entrySet() with BeanShell:
for(Map.Entry entry : row.entrySet())
{
log.info(entry.getKey() + "=" + entry.getValue());
}
See various ways to iterate through Map here.
I'm getting this error when trying to build the app:
<unknown>:0: error: cannot assign value of type 'Array<_>' to type 'Array'
but Xcode is not indicating a specific line or class for the failure.
If I could understand the difference between
Array<_>
&
Array
it may help me locate the issue.
When you app is crashing, than you can turn on All Exceptions for Debug breakpoint. This should stop on the line where the crash appears.
You find this in Xcode on the Left Panel-> BreakPoint Navigator.
Than press the + in the bottome left corner and Add Exception Breakpoint.
It looks like that you overwrite an array with an array that has a specific value definition. Good Luck :)
A generic argument clause is enclosed in angle brackets ( < > )
< generic argument list >
You can replace a type parameter with a type argument that is itself a specialized version of a generic type.For example, you can replace the type parameter T in Array < T > with a specialized version of an array, Array< Int > , Array< String >, to form an array whose elements are themselves array of integers / Strings
Regarding xour code Snippet the fix is:
u should define it with the right value ... userTweetsArray : [String] = String . or remove the : [String] because setting the value defines already the object and type :)
I don't like answering my own questions but for the sake of closure
I had this line of code
var userTweetsArray : Array = [String]()
I never actually used it. Once I removed that line the error had gone.
The error was caused by assigning an array of a type in this case String to an Array of no type.
So difference is Array<_> is an array of a type and Array is not.
