When I try to access the form in Edit mode I get a critical error (see error report below). How do I debug this? Is it possible to retrieve the form config data?

I've managed to export the module contents in xml format. It's a huge file (350K) with hundreds of form fields! Is it possible to re-import this xml file into a new form module?

I was able to export form content as xml file and then break up the form into 5 separate forms. Found an error on two field short names (i.e. short names should not include the character ').

Can I disable the quick edit in the xml file prior to importing it? What's the tag name?

I found the tags and disabled the quick edit and drag/drop settings then reimported the consolidated form. This solved the problem.
