That's ok.

Try to do a debug output on _each_ setVisible which you do. Check if they are really called when you expect it.

Hello...

sorry for bothering you so long...
I now found it was my fault ...
its not exactly like I override the visibility but I do not initialise the condtion for shouldbeVisible...

thanks for all!
