This is a rather serious bug - not being able to save. Are you able to reproduce it? Could you possibly share the original GUI form where it happen? Do you remember the steps that lead to the problem? Any clue is welcomed.

The exception itself only shows what is broken in the model (missing layout component for a visual component in the form), but is not sufficient to identify how it happened. Other exceptions show some problems when trying to align components, which would also be nice to have steps for, but this should not cause the save breakage. Thanks!
