Debugging LCDS Data Management from Flexbuilder3 on Tomcat does not work

I have a sample with Data Management and when i use it on my tomcat it works fine. But i can´t debug it from flexbuilder 3. When i start it from the flexbuilder i get the connection and then i crashed with "No registered fault handler or token responder - throwing an error for destination:"
It is the same tomcat i use to run standalone.
is it a problem with the context.xml?
