Hi All,<br>        I&#39;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 <b>each and every process</b>.<br>

<br><b>unable to build expression for &#39;constraint&#39; null&#39;: java.lang.NullPointerException</b><br><br> I tried validating each process using the jbpm designer and they show no errors. Can someone help me with this. Thanks in advance.<br>
