Comment 2 Jan Stola 2011-10-22 15:40:17 UTC 
The corresponding lines are

  FormServices services = Lookup.getDefault().lookup(FormServices.class);
  MultiDataObject.Entry entry = services.createPrimaryEntry(obj, primaryFile);

The attached exception shows that services is null. This is really strange. Lookup should return NbFormServices registered in form.nb module (the attached message log shows that form.nb module is enabled).

message.log shows several exceptions related to MetaInfServicesLookup. Therefore, the root of this issue seems to be outside GUI Builder. It seems that the lookup got corrupted/incomplete somehow.

Unfortunately, I am not able to reproduce this issue. Are you still able to reproduce it? If so, could you, please, provide more details? It would be ideal to provide exact steps to reproduce (starting with a new/empty user-dir).
