Hey,
I have developed class library and used it for event handlers, and it is hitting the code.
on the OnUpdating function after canceling the event, a red error message appears on the page (in the validation area) says "an has error occurred when saving your project to the server. please contact your administrator for assistance."
in my function I have just couple of code lines inside try catch scope:
e.CancelReason = "test cancel reason";
e.Cancel = true;
this scenario is working fine on OnCreating event handler, as a dialog box appears with the cancel reason in it (though there will be some fail jobs in the queue, but not show stopper ... please advise if you can)
but when I try to save a project from project information page I get the described scenario.
working with Project Server 2010 with cumulative Update June 2011 (KB2536600), July 2012 (KB2598355) and Sharepoint and Project Server 2010 Service Pack 1 (SP1)
