Classic Servoy

Hello,

on one of my forms I get an error when doing controller.find(). Can anyone see from the log what goes wrong here?:

I narrowed the problem: the form that is giving the error has a tab panel that also shows tabs of a module. That module was not present when I did controller.find(). If the module is there, I don’t get that error.

Added more checks to prevent, will be availeble in Servoy 2.2 rc6/final
