Error installing JPBM JPDL Designer 3.0.13

anthony.mcclay Jan 28, 2008 2:20 PM

I am unable to upgrade to 3.1 base code.

I am using both MyEclipse 5.5.1 and als a newly downloaded version of Eclipse 3.2.2 and the jbpm-jpdl-designer-3.0.13.zip from the sourceforge download site.

I receive the error when I open the JPL Designer Editor

In both cases I get a null pointer Exception.

Base configuration:

Java Version
C:\Documents and Settings\mcclayac>java -version
java version "1.5.0_14"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_14-b03)
Java HotSpot(TM) Client VM (build 1.5.0_14-b03, mixed mode, sharing)
NOTE ( 1.5.0_13 no longer avilaable)

JBPM Designer version:
jbpm-jpdl-designer-3.0.13
jbpm-jpdl-designer-nodeps-3.0.13

FACTS:
#1. I received the following error using both instalations (See Below)
#2. Both versions seem to be dependent on version of Jface
version 3.2.2.M20061214-1200
