This exception occurs when you use XRM.ActivityParty in your Offline Plugin. In this case you have to change your Plug-in code in order to solve this issue.


Example :


If you use the following code:

Example

ActivityParty activitypartyentity=new ActivityParty();

....

Or

ActivityParty[] arrayofactivityparty=....

You have to change your code as the following:

Example

Entity activitypartyentity=new Entity("activityparty");

....

..

or

Entity[] arrayofactivityparty=....
