I'm using Eclipse 2.1 with Eclipse UML
Windows 2000
Eclipse 2.1.3
GEF 2.1.2
EcliplseUML 1.2.1

I try to generate sequence diagrams and nothing happens after I press "Finish" on the Sequence Diagram dialog box. The Eclipse logs
show the following (all help greatly appreciated):

*** Stack trace of contained exception ***

I'm also getting the same behavior. I have eclipse 3.0, Windows XP, and java 1.4.02. I am using the GEF and eclipseUML distributed with the enterprise trial download.
