[atarkowska]

this was caused by countChildren on PlateWrapper?. I can remove this statements from the code, but we should address this issue in the next version.
In theory ScreenWrapper? children are Plates. PlateWrapper? children are Wells but we should handle PlateAcquasition? and WellSample?.

We need to discuss this how that should work and open new tickets in 4.3.1.

Problem should be fixed temporarily.
