JBoss jBPM Process Designer Getting Started
Hi,
I am using eclipse 3.1.2 as I can't find 3.1 m7.
When I try to follow the example in "JBoss jBPM Process Designer Getting Started" (found in the jboss's site jbpm documentation), I encounter error during the "Action" creation part; the error is as follow :
java.lang.NullPointerException

The error log shows that this error is come from org.eclipse.jface plugin, I really got no idea how to work this around. Anyone encountered this problem before ? If you did, pls shine the problems. Thank you in advance.
