<P><FONT SIZE=2 FACE="Arial">MyMatcher class just contains a "return obj instanceof MyClass" in it and the convertor object just returns a constant test string as the conversion to and from the database.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">If I step through the list of the JbpmTypes from the object factory calling match() with an instant of MyClass I get a null pointer from the JbpmType that I think corresponds to the one I have written.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">If I run a workflow ProcessInstance containing an action handler that attempts to store an instance of MyClass I get an hibernate exception complaining that I was attempting to put a non persistent variable into a persistent store.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Any suggestions would be helpful, I am at my wits end trying to get this fixed … I expect I have missed a simple step somewhere.</FONT></P>
