I am using CRM

Microsoft Dynamics® CRM 2016(8.1.0.359) (DB 8.1.0.359)

I am using a custom action and plugin.

The output parameter that I am setting is called "IsStatus". I response result is coming back with nothing. Not sure what I am doing wrong.

javascript code - responseText is coming back with nothing

$.ajax({
     url: organizationUrl + "/api/data/v8.0/new_CreateNewCaseDataSheet",
     type: 'POST',
     contentType: "application/json; charset=utf-8",
     datatype: "json",
     data: data,
     success: function (responseText) {
         //var jsonData = JSON.stringify(responseText); 
         //var getStatus = JSON.parse(this.responseText);
         //isStatus = getStatus.isStatus;
         alert(" -- Action Called - 23");
         //    updateMap(myArr); 
         window.close();
         return false;
         
          },

Plugin Code

       // TODO: Implement your custom Plug-in business logic.
       IPluginExecutionContext context = localContext.PluginExecutionContext;
       IOrganizationService service = localContext.OrganizationService;

       if (context.InputParameters.Contains("EntityArg") && context.InputParameters["EntityArg"] is Entity)
       {
           context.OutputParameters["IsStatus"] = false;
           bool isStatus = true;
           context.OutputParameters["IsStatus"] = isStatus;
       }

RE: Custom Action Output Parameter not being returned from the plugin

I had similar issue and found, if a mandatory output parameter is set in PRE stage they are overridden by the framework before the hit the client, while setting them in POST stage it works as it should.

The PRE | POST pattern i not really that relevant for actions, because in most cases you just need one hook where you can put your synchronized code, so i simply changed my plugin to be registred on POST event rather than PRE event, and now i get values from the OutputParameters back to the client as expected..

Hi Andrew,

With the help of this link https://arunpotti.wordpress.com/2014/11/30/html-webresource-example-in-crm/

I manage to fix my issue. Here's the working code.

function CallActionPlugin(datatracking) { var isStatus; var organizationUrl = serverUrl; var query = "new_CreateNewCaseDataSheet" var data = JSON.stringify(datatracking); $.ajax({ url: organizationUrl + "/api/data/v8.0/" + query, type: 'POST', contentType: "application/json; charset=utf-8", async: false, datatype: "json", data: data, beforeSend: function (XMLHttpRequest) { //Specifying this header ensures that the results will be returned as JSON. XMLHttpRequest.setRequestHeader("Accept", "application/json"); }, success: function (responseText) { var jsonData = JSON.stringify(responseText); var getStatus = JSON.parse(jsonData); isStatus = getStatus.IsStatus; alert(" -- Action Called - 23");
window.close(); return false; }, error: function (jqXHR, exception) { var msg = ''; if (jqXHR.status === 0) { msg = 'Not connect.\n Verify Network.'; } else if (jqXHR.status == 404) { msg = 'Requested page not found. [404]'; } else if (jqXHR.status == 500) { msg = 'Internal Server Error [500].'; } else if (exception === 'parsererror') { msg = 'Requested JSON parse failed.'; } else if (exception === 'timeout') { msg = 'Time out error.'; } else if (exception === 'abort') { msg = 'Ajax request aborted.'; } else { msg = 'Uncaught Error.\n' + jqXHR.responseText; } alert(msg); } }); }

Hi Andrew,

Here's what I am seeing in the metadata

<ComplexType Name="new_CreateNewCaseDataSheetResponse">

<Property Name="IsStatus" Type="Edm.Boolean" Nullable="false"/>

</ComplexType>

<Action Name="new_CreateNewCaseDataSheet">

<Parameter Name="EntityArg" Type="mscrm.new_datatracking"/>

<ReturnType Type="mscrm.new_CreateNewCaseDataSheetResponse" Nullable="false"/>

</Action>

Can you check /api/data/v8.0/$metadata . Check that output argument is available there.

Plugin that is setting the output Parameter to true.

The response is coming back with nothing.

Ok. That shows that your code works and reaches setting of value.

Can you please provide code that you use to check output value?

That piece of your code in initial post is commented out:

//var getStatus = JSON.parse(this.responseText);

//isStatus = getStatus.isStatus;

Even if you will use it you should use IsStatus and not isStatus.

Good luck.

Did not show all this code.

var XrmP = window.top.opener.frames[0].Xrm;

I mean your JS code is not valid. It will not work.

Regarding fact that "your input parameters are working in the plugin" - why are you so sure?
