Any chance you could share the GUI form where the exception happened and descirbe steps to reproduce? I'm afraid we 
are not able to fix this just based on the exception itself. The exception looks like the layout model hierarchy is in 
a state that I have no idea how could happen (lookes like if one layout element obtained from a group had not point 
back to its parent).
