Hi All,

I'm having the following error while deserialing a workingmemory object:

java.lang.ClassNotFoundException: com.oss.activation.rules.core.types.StepShadowProxy

    at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1304)

com.oss.activation.rules.core.types.Step is one of ower types that are in the WorkingMemory as facts. I don't know about com.oss.activation.rules.core.types.StepShadowProxy, I supose is a DROOLS generated class.

Any ideas of what could be wrong here?

Thanks!

Pedro Costa.
