class cast exception in drools that makes no sense: seam 2.3, eap 6.1
I cannot understand this. MVELDialectConfiguration implements DialectConfiguration. They are in the same jar file. I've built this application using the seam 2.3 maven bom which specifies the version of drools to use.
How can I get out of this?
