We have the same requirement of passing huge data like http://bugsquash.blogspot.in/2010/12/customizing-solrnet.html, we tried the following.
1) Increased the requestHeaderSize to Int32.MaxValue - stackoverflow exception
2) Used PostSolrconnection - got the StackOverflow exception.
3) Downloaded the source of solrnet and added as project reference - Stackoverflow exception
Then even we changed to GET, we are getting the StackOverflow exception. The error is coming when we have more than 500 reference ids. If we have less values, it works.
This is how we are calling,
searchResults = solrPost.Query(new SolrMultipleCriteriaQuery(new[]
{
query
}),
new SolrNet.Commands.Parameters.QueryOptions
{
Fields = new[] { "*", "score" },
Start = pageSize,
Rows = 40,
OrderBy = listSort
});
Any ideas?
EDIT:
We tried requesting solr using HttpRequest and identified as maxBooleanClause issue and then POST started working through HttpRequest. But using SolrNet the error is occurred and it is happening at serializing the query object. queryserializer.serialize(Query)
Wondering why step 2 didn't work which is the exact fix for the long Get request issue, i.e. to switch over to Post request.
Chances are there is an issue with the piece of code where you are initialising SolrNet to use PostSolrConnection instead of the default SolrConnection. Need to look at the bit of code which gets you the instance of solrPost object. Take another look at it and post it here.
Unfortunately the SolrNet didn't work due to stackoverflow error while serializing the query parameters. Alternate workaround is posted http://smartcoder.in/solrnetstackoverflow/

For some reason that I don't understand, on my development machine can't call to function of a cfc component from a cfajaxproxy.
In my cfm document:
<cfajaxproxy cfc="#Application.CfcPath#.empleado"
jsclassname="ccEmpleado">
This works, and also I can instantiate an object to get all the functions of that cfc component:
var cfcEmpleado = new ccEmpleado();
But, when I try to call a function of that object:
var nb_Empleado = cfcEmpleado.RSEmpeladoNombreBIND(1,1);
Debug complains:
Error: The ID_EMPRESA parameter to the RSEmpeladoNombreBIND function is required but was not passed in.
I got this from Network tab on Chrome and figured out that something is generating an invalid parameter:
http://127.0.0.1/vpa/componentes/empleado.cfc?method=RSEmpeladoNombreBIND&_cf_ajaxproxytoken=[object%20Object]&returnFormat=json&_cf_nodebug=true&_cf_nocache=true&_cf_clientid=41C92098C98042112AE2B3AAF523F289&_cf_rc=0
As you can see, there's a parameter [object%20Object], that is messing around my request, and that's why it fails. I don't why is happening this. Other people has tested this, and it works, but in mine doesn't.
I have Coldfusion 9, Apache, Windows 8. Is is some configuration issue on Coldfusion, or a bug?
I can't tell if this is your error or not, but it might be. This was a problem that we had for awhile. You should consider using explicit names to avoid any confusion. Add the "js" in there.
<cfajaxproxy cfc="cfcEmpleado" jsclassname="proxyEmpleado">
var jsEmpleado = new proxyEmpleado();
I will try to find a link to an article about this very thing.
I'm trying to calculate the tf*idf of a term in my index.
Following Yonik's post from http://yonik.com/posts/solr-relevancy-function-queries/ I tried
http://localhost:8080/solr/select/?fl=score,id&defType=func&q=mul(tf(texto_completo,bug),idf(texto,bug))
(where texto_completo is the field, and 'bug' is the term) without much success. The response was:
error 400: The request sent by the client was syntactically incorrect (null).
I went ahead and looked at this answer /a/13477887 so I tried to do a simpler function query:
http://localhost:8080/solr/select/?q={!func}docFreq(texto_completo,bug)
And yet, I got the same error.
What is my syntax lacking to work properly?
For this not working:
q={!func}docFreq(texto_completo,bug)
use all lower-case docfreq:
q={!func}docfreq(texto_completo,bug)
I just tried:
q={!func}mul(tf(name,movie),idf(name,movie))
in Solr 4.2.1 and it is working fine. My field name is name (Text type) and term I am looking for is movie.
UPDATE: You need at least Solr 4.0 to use these. See http://wiki.apache.org/solr/FunctionQuery#Relevance_Functions
I'm trying to serialize objects as JSON with MVC4 WebAPI (RTM - just installed VS2012 RTM today but was having this problem yesterday in the RC) and I'd like for all nulls to be rendered in the JSON output.
Like this:
[{"Id": 1, "PropertyThatMightBeNull": null},{"Id":2, "PropertyThatMightBeNull": null}]
But what Im getting is
[{"Id":1},{"Id":2}]
I've found this Q/A WebApi doesnt serialize null fields but the answer either doesn't work for me or I'm failing to grasp where to put the answer.
Here's what I've tried:
In Global.asax.cs's Application_Start, I added:
var json = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
json.SerializerSettings.NullValueHandling = Newtonsoft.Json.NullValueHandling.Include;
json.SerializerSettings.DefaultValueHandling = Newtonsoft.Json.DefaultValueHandling.Include;
This doesn't (seem to) error and seems to actually execute based on looking at the next thing I tried.
In a controller method (in a subclass of ApiController), added:
base.Configuration.Formatters.JsonFormatter.SerializerSettings.NullValueHandling = Newtonsoft.Json.NullValueHandling.Include;
base.Configuration.Formatters.JsonFormatter.SerializerSettings.DefaultValueHandling = Newtonsoft.Json.DefaultValueHandling.Include;
I say #1 executed because both values in #2 were already set before those lines ran as I stepped through.
In a desperation move (because I REALLY don't want to decorate every property of every object) I tried adding this attrib to a property that was null and absent:
[JsonProperty(DefaultValueHandling = DefaultValueHandling.Include,
NullValueHandling = NullValueHandling.Include)]
All three produce the same JSON with null properties omitted.
Additional notes:
Running locally in IIS (tried built in too), Windows 7, VS2012 RTM.
Controller methods return List -- tried IEnumerable too
The objects I'm trying to serialize are pocos.
This won't work:
var json = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
json.SerializerSettings.NullValueHandling = Newtonsoft.Json.NullValueHandling.Include;
But this does:
GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings = new Newtonsoft.Json.JsonSerializerSettings()
{
NullValueHandling = Newtonsoft.Json.NullValueHandling.Include
};
For some odd reason the Newtonsoft.Json.JsonFormatter ignore assigments to the propreties os SerializerSettings.
In order to make your setting work create new instance of .SerializerSettings as shown below:
config.Formatters.JsonFormatter.SerializerSettings = new Newtonsoft.Json.JsonSerializerSettings
{
DefaultValueHandling = Newtonsoft.Json.DefaultValueHandling.Include,
NullValueHandling = Newtonsoft.Json.NullValueHandling.Include,
};
I finally came across this http://forums.asp.net/t/1824580.aspx/1?Serializing+to+JSON+Nullable+Date+gets+ommitted+using+Json+NET+and+Web+API+despite+specifying+NullValueHandling which describes what I was experiencing as a bug in the beta that was fixed for the RTM.
Though I had installed VS2012 RTM, my project was still using all the nuget packages that the beta came with. So I nugetted (nugot?) updates for everything and all is now well (using #1 from my question). Though I'm feeling silly for having burned half a day.
When I saw this answer I was upset because I was already doing this and yet my problem still existed. My problem rooted back to the fact that my object implemented an interface that included a nullable type, so, I had a contract stating if you want to implement me you have to have one of these, and a serializer saying if one of those is null don't include it. BOOM!
I am trying to implement a custom web resource using jquery/ajax and odata. I ran into trouble and eventually found that when I call:
var serverUrl = context.getServerUrl();
The code throws exceptions.
However, when I change serverUrl to the literal url, it works. I then found forum posts that said I should verify my .aspx page manually by going to https://[org url]//WebResources/ClientGlobalContext.js.aspx to verify that it is working. When I did that I received a warning page:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.

What the heck does that mean?
Hard to tell outside of context (pun not intended) of your code, but why aren't you doing this?
var serverUrl = Xrm.Page.context.getServerUrl();
(Presumably, because you have defined your own context var?)
Also, this method is deprecated as of Rollup 12, see here: http://msdn.microsoft.com/en-us/library/d7d0b052-abca-4f81-9b86-0b9dc5e62a66. You can now use getClientUrl instead.
I now it is late but hope this will be useful for other people who will face this problem.
Until nowadays even with R15 there are two available ClientGlobalContext.js.aspx
https://[org url]/WebResources/ClientGlobalContext.js.aspx (the bad one)
https://[org url]/[organization name]/[publication id]/WebResources/ClientGlobalContext.js.aspx (The good one)
I don't know why exist 1. but it causes many issues like:
It could not be published or hold information (Your case #Steve).
In a deployment with multiple organizations, seems it saves info only for the last organization deployed causing that methods under Xrm.Page.context. will return info from a fixed organization. Actually each method that underground uses these constants included in ClientGlobalContext.js.aspx: USER_GUID, ORG_LANGUAGE_CODE, ORG_UNIQUE_NAME, SERVER_URL, USER_LANGUAGE_CODE, USER_ROLES, CRM2007_WEBSERVICE_NS, CRM2007_CORETYPES_NS, AUTHENTICATION_TYPE, CURRENT_THEME_TYPE, CURRENT_WEB_THEME, IS_OUTLOOK_CLIENT, IS_OUTLOOK_LAPTOP_CLIENT, IS_OUTLOOK_14_CLIENT, IS_ONLINE, LOCID_UNRECOGNIZE_DOTC, EDIT_PRELOAD, WEB_SERVER_HOST, WEB_SERVER_PORT, IS_PATHBASEDURLS, LOCID_UNRECOGNIZE_DOTC, EDIT_PRELOAD, WEB_RESOURCE_ORG_VERSION_NUMBER, YAMMER_IS_INSTALLED, YAMMER_IS_CONFIGURED_FOR_ORG, YAMMER_APP_ID, YAMMER_NETWORK_NAME, YAMMER_GROUP_ID, YAMMER_TOKEN_EXPIRED, YAMMER_IS_CONFIGURED_FOR_USER, YAMMER_HAS_CONFIGURE_PRIVILEGE, YAMMER_POST_METHOD. For instance method Xrm.Page.context.getUserId() is implemented as return window.USER_GUID;

I have a coworker who's written the following line in the page load method in an aspx page:
myDataSet = (DataSet)HttpContext.Current.Cache["dataset"];
The first time I hit the page HttpContext.Current.Cache["dataset"] reads null. When he does it, the value is "" (string.Empty) and he gets a cast exception.
We're both running ASP.Net 2.0 on our development machines, he's cleared his browser cache and run an iisreset, yet that thing still reads "" the first time he hits the page. Does anyone have ideas on what we can check to explain this discrepancy?
Try this instead for now, you'll at least avoid hitting the exception:
myDataSet = HttpContext.Current.Cache["dataset"] as DataSet;
I'd search your code and see what is actually assigning "dataset" into the cache. Something's got to be putting an empty string in there. Finding that may lead you to some other code that would explain the different results.
Without any real code samples, it's hard to troubleshoot.
Perhaps you should try to use HttpRuntime.Cache instead of the HttpContext.Current.Cache.

Difference between HttpRuntime.Cache and HttpContext.Current.Cache?
