This can be solved in an even better way. As designmode works mostly on 
RenderObjects, potential error messages need also to be implemented as 
RenderObjects. However, and here goes the trick, not every render object has 
to be associated with a document node. So, in the kafka part, you wouldn't 
even "see" those nodes, thus inadvertently changing it is impossible. (There 
certainly must be an API that enables setting/clearing those error render 
objects, but that's far in the future for now.)

Yeah, you're welcome. This stuff is not directly related to designmode anyway. 
I especially consider resizing of tables to be non-trivial ;-)
