I have modelled a process in Guvnor web designer

. I have imported the diagram into the Eclipse succesfully, but after i tried run it in eclipse, I ger thousands of errors.

This happens when i use timer events that are attached to a task border (I guess it should interrupt the task after some period of time).Here is the diagram i want to run in Eclispe:

Here is part of what I get when I try to run the example:

 

Hello Guvnor World

Process started ...

Im in goodbye
