Question: I recently made a few changes to the TicketDetails form. When I started building I received this error:
INFO – Building Quick Form: ‘TicketDetails’.
ERROR –
NVelocity.Exception.MethodInvocationException: Invocation of method ‘getControlServerCode’ in Sage.Platform.QuickForms.WebFormGen.WebUserControlGenerator threw exception System.NullReferenceException : Object reference not set to an instance of an object. —> System.NullReferenceException: Object reference not set to an instance of an object.

Why is this happening?
Answer: When you delete Type, Reseller, and Lead Source fields there are “User Interface interaction” items you need to modify in the Load Actions for the form, as well as in the OnChange action of the Account lookup control.
Remove entries in the actions that refer to controls you remove. If references are left, the quickform builder can’t find them when it is building the page, and it will give you the same error message.
