I am having the same problem. Has anyone got this working?
I have tried using mvel version 1.2.8 and 1.2.10 in the classpath of
drools-insurance ( where the jUnit tests are ) and by both the
serialVersionUID is different. So can anyone tell me which version of
mvel is needed to get this working?
Thx,
Waruzjan
