Thanks Jan Pieter,

It will help more people to become aware of the problem if the bug description is also posted here.

So here it is.

Ken

Crash on entering Sample Population for fact type (fact type that is in error mode).

Reproduce:
by adding the attched orm file to a new VS2013 sln.
FT: Profile has TimeStepSize. Enter '5 minutes' or '5' ...
Then this unhanndled exception occurs.

System.NullReferenceException was unhandled
Message: An unhandled exception of type 'System.NullReferenceException' occurred in Microsoft.VisualStudio.VirtualTreeGrid.dll
Additional information: Object reference not set to an instance of an object.

Hi JP,

Yes, you're in a serious error mode here with no identifying value type for your entity type. The issue is the preferred identifier pattern still holds, but the identifying value type is no more. I'm not sure I should even allow the PID to exist in this state, but I'm sure that changing that workflow would be much harder than doing a null reference check to fix the sample population crash.
