Hi,<br>
<br>
I am new to drools flow and have the question below.<br>
<br>
After enabling persisentence (JPA) on the process side and<br>
using the out of the box WSHumanTaskHandler.<br>
<br>
Ran into a java.lang.NullPointerException on completing<br>
the Human Task (used the Eclipse Human Task view to do it)<br>
<br>

Am I missing something or does the WSHumanTaskHander not support<br>
the above ?<br>
<br>
<br>
Note:-<br>
Was able to get these pieces working when process was<br>
not using JPA persistence.<br>
<br>
Thanks<br>
Sanjay<br>
