  Hello,

  From my point of view the best way is to create some fake attribute and store message that should appear inside this attribute. Once record is saved and plugin is triggered you can retrieve this value using Rest EndPoint.

  Hi,

  when issuing a request to OData to trigger the plugin, you can view the error in Fiddler. I tried this out and this is what I got in the error:

  {
  "error": {
  "code": "-2147220891", "message": {
  "lang": "de-DE", "value": "test"
  }
  }
  }

  
  

  In my plugin I did this:

  throw new InvalidPluginExecutionException("test");

  
  

  So you can see the error message in the value property of the error in the response as shown above.

  Greetings,
  Pavlos

  Pseudocode:

  instead of

  throw new InvalidPluginException("test exception");

  
  

  you can use

  Update Entity.Field = "test exception";
  return;

  So one exception equals to one message. Not sure how you wanted to use multiple exceptions. Could you in-light me how it could be used?

  @ Andrii - suppose i am performing two actions in my plug-in 1. retrieve accounts 2. update contacts. Now i have two try catch blocks for both these actions. How can i identify to show "accouts retreival failure" or "update contacts failure" alert?

  @ Pavlos - yes you are right, even i could also see the same but that just help us to resolve plug-in errors. My concern is to show that error as an alert message via JavaScript.

  Ok. Again pseudocode because I don't to write real code for this easy task...

  try
  {
  	//Retreive accounts code
  }
  catch(Exception e)
  {
  	Update entity field to "1. error during retrieval of accounts" + e.Message;
  	return;
  }
  
  try
  {
  	//update contacts code
  }
  catch(Exception e)
  {
  	Update entity field to "2. error during update of contacts" + e.Message;
  	return;
  }
  

  
  In JS I believe you can get first char of string. In case it would be 1 - Exception occurred during retrieval of accounts. Otherwise in case it would be 2 (you would not guess) - Exception occurred during update of contacts.

  Hello Andrii

  I completely understood you while you specified to update the entity field from plug-in. Actually the concern was JavaScript code

  Hello Ankit,

  maybe I misunderstood, but aren't you using JS to update a field of the entity using the ribbon button? Something like this?

   $.ajax({
          type: "GET",
          contentType: "application/json; charset=utf-8",
          datatype: "json",
          url: serverUrl + ODATA_ENDPOINT + myQuery,
          beforeSend: function(XMLHttpRequest) {
              XMLHttpRequest.setRequestHeader("Accept", "application/json");
          },
          success: function(data, textStatus, XmlHttpRequest) {
              successCallBack(data.d, textStatus, XmlHttpRequest);
          },
          error: function(XmlHttpRequest, textStatus, errorThrown) {
              errorHandler(XmlHttpRequest, textStatus, errorThrown);
          }
      });

  if yes, then you can do this in your error callback to show your message:

  function errorHandler(xmlHttpRequest, textStatus, errorThrown) {
      alert(JSON.parse(xmlHttpRequest.responseText).error.message.value);
  }

  This message will contain the message from the plugin exception.

  Hope I understood your requirement right.

  Greetings,

  Pavlos
