Recently I came across an issue where I would like to propagate the plug-in InvalidPluginExcecutionException message via JavaScript code. Based on the client requirements I need to trigger a plug-in on click of custom ribbon button on the Opportunity entity. Hence on custom button click I have written a web service call that updates one of custom attributes of an Opportunity entity. So, when system will update this field via client side web service call, the registered plug-in will be triggered automatically.
Usually your InvalidPluginExcecutionException message inside your plug-in code is displayed to user in a standard CRM message box. In my case I am unable to see the same because the plug-in is being triggered via JavaScript web service call. Below is the code snippet that executes my query.
//Asynchronous AJAX function to update a CRM record using OData $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", datatype: "json",data: jsonEntity,
url: serverUrl + ODATA_ENDPOINT + "/" + odataSetName + "(guid'" + id + "')",
beforeSend: function (XMLHttpRequest) { //Specifying this header ensures that the results will be returned as JSON. XMLHttpRequest.setRequestHeader("Accept", "application/json");
//Specify the HTTP method MERGE to update just the changes you are submitting. XMLHttpRequest.setRequestHeader("X-HTTP-Method", "MERGE");
},
success: function (data, textStatus, XmlHttpRequest) { //The MERGE does not return any data at all, so we'll add the id //onto the data object so it can be leveraged in a Callback. When data //is used in the callback function, the field will be named generically, "id" data = new Object();data.id = id;
if (successCallback) {successCallback(data, textStatus, XmlHttpRequest);
}
},
error: function (XmlHttpRequest, textStatus, errorThrown) { if (errorCallback) {errorCallback(XmlHttpRequest, textStatus, errorThrown);
}
else {ErrorHandler(XmlHttpRequest, textStatus, errorThrown);
}
}
});
I have validated all the 3 objects i.e. XmlHttpRequest, textStatus and errorThrown inside errorCallback method to seek the plug-in error message with no success. However I can see the same error message via fiddler!!
Finally, I found a way to parse the response text of xmlHttpRequest and get the exact error message. Below is the code that works for me to alert the plug-in message from client side code.
function ErrorHandler(xmlHttpRequest, textStatus, errorThrown) {alert(JSON.parse(xmlHttpRequest.responseText).error.message.value);
}
I hope this will be helpful.
