To add to what Thad said, your map should look like this "Map formData" since the key of the map looks like a String, and your

You're formData map is probably null. Just a guess, but I think you need to
be more specific with your Map class, using, say Map or something more

I decided to edit the example page to see if I could actually do
something and created a Label "timeLabel". Then I attempted to add it

If you can reproduce this consistently it may be a compiler bug. It
sounds as though the code is getting optimised out.
GWT Team - is there a way to debug this situation with SOYC?

Ok, it appears I have fixed this issue. For future reference it seems
that the AsyncCallback calls were causing the errors. I basically
added 'type' parameters to every AsyncCallback and this solved the
issue I was having!
Thanks for your help.

a System.out.println call on the selectOrdersBeingPrepared method to
observe what was happening. It seems th

dc is creates a Database Connector object. I'm not sure why there
would be two parallel calls as the connection to the database is
closed after every call...
