Hi All, I've a set of bmpn2 processes. When I try to compile them locally, its compiles fine. But when I upload them to the Guvnor and try to build the package, I get the below mentioned error for *each and every process*. *unable to build expression for 'constraint' null': java.lang.NullPointerException* I tried validating each process using the jbpm designer and they show no errors. Can someone help me with this. Thanks in advance. -- cheers Sumatheja Dasararaju _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
