[rules-users] process-designer deserialization error

[Kris Verlaenen]

Hi,

Yes, the NPE you are getting is because the package as defined in the 
process is not the same as the package in Guvnor.  You can set the 
package of your process either by changing the XML file as you 
described, but there is also a package name property on the process 
(just click the background of your process and check the properties 
view).  You should be able to build your process on Guvnor if package 
names match.
