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.
