Hi all,
I'm just trying to run through the GEF shapes example, and I'm blocked on a strange behavior. I just imported the src into a new plug in project which I have created. I am just trying to run it and I get the following error.
Unhandled event loop exception
Reason:
java.lang.NullPointerException
In the .log file, I find the exception shown at the end of this messasge. I'm running Eclipse 3.1 . Can someone give me a hint? I'm totally lost!
Thanks in advance,
Eswar
