Michael Neale commented on JBRULES-1152:
----------------------------------------

As an immediate suggestion, using the bean property change listener is not recommended anymore. 

By using "dialect 'mvel' " as a rule attribute (or package) you can do:

modify(fact) { field = value , ... } 

etc... this will mean that the bean property change listener can be removed, and performance increased as each little change doesn't notify the engine. 

But this is still worth looking into, as it may be covering up another problem. My suggestion is to get rid of the bean property listener and see if the rules behave as expected.

> Sorry, I don't have very specific information.  Some of my project's unit tests are hanging with drools 4.0.1.  No error, just not completing.  I tried to debug a bit but could not figure it out.  Consider this an early warning until I can gather more info.
> Everything worked fine with 4.0 so I went back to that.
