Layout Problem with Nuxeo Studio

My edit form looks like that :

In studio, trying to insert a new column in this layout shows the nature of the problem :

If i move all fields in the same column, i have a GWT error.

Help me save my layout !

My DIY solution :

create a row, move the widget in, delete the old row.
