[rules-users] Problem when I cleaning the production memory.

[braveheart85]

Yesterday I tried version 5.6. I have had a problem with the MVEL syntax.

rule "RULE1"
  $result: PersonData( businessActivity.status == "CLOSED" )
end

This rule that works in the version 5.5, now have a problem in version 5.6:

unable to invoke method:
org.titan.registry.filter.BusinessActivityData.getStatus: target of method
is null

The problem is that not all Person facts inside the working memory have a
business activity. NullPointer would be quite correct but in version 5.5 the
behaviour was different...

Maybe I'm abusing of your kindness.
