Comment 1 Jan Stola 2008-07-31 15:57:59 UTC 
This exception can occur when some form with corrupted guarded blocks
is opened and custom property editor for pre/post init/creation code
is invoked.

Related issue 138996 has been fixed recently - it ensures that
the form is marked as read-only when the guarded blocks are
corrupted. Unfortunately, some custom property editors do not check
whether the form is read-only and expect guarded blocks to be
in a good shape.

I have fixed JavaCodeGenerator.CodeEditor and RADConnectionPropertyEditor.
