Re: [rules-users] java.lang.ClassCastException: org.drools.reteoo.BetaMemory cannot be cast to org.drools.reteoo.AlphaNode$AlphaMemory
Hi,
nice to find this topic, I'm experiencing the same problem.
Actually I have that "complex scenario", that was mentioned, like "add and
remove rules dynamically from a knowledge base".
Does it mean that there is a known bug and it's going to be fixed? At this
case is there any temporal workaround?
Or it means that adding or removing rules dynamically is not something that
should be used at all?
The Drools version is 5.5.0.Final
Thank you very much in advance,
Vlad.

very serious issue in 5.5.
Causes could be an invalid rule in the first place (running the engine
without checking for compilation errors), a bug in the construction
process
(unlikely, unless the rule is a very rare edge case), or a complex
scenario
where you add and remove rules dynamically from a knowledge base....
