Ok, now the query works.
However I have noticed that when that rule with (. instead of !.) fails,
Drools can't remove the rule in the cleaning phase like the version 5.5.0. I
have found these logs in my console:
09:47:31,989 INFO [http-bio-8080-exec-8][WorkingMemoryConsoleLogger:114]
BEFORE PACKAGE ADDED package: "org.titan.memory.drools.command.custom"
09:47:31,990 INFO [http-bio-8080-exec-8][WorkingMemoryConsoleLogger:114]
BEFORE PACKAGE ADDED package: "org.titan.registry.filter"
09:47:31,992 INFO [http-bio-8080-exec-8][WorkingMemoryConsoleLogger:114]
BEFORE RULE ADDED package: "org.titan.memory.drools.command.custom" rule:
"dis"
then:
java.lang.RuntimeException: cannot invoke getter: getBusinessActivity ....
then:
09:47:32,373 INFO [http-bio-8080-exec-8][WorkingMemoryConsoleLogger:114]
BEFORE PACKAGE REMOVED package: "org.titan.memory.drools.command.custom"
09:47:32,373 INFO [http-bio-8080-exec-8][WorkingMemoryConsoleLogger:114]
BEFORE RULE REMOVED package: "org.titan.memory.drools.command.custom" rule:
"dis"
and finally:
Caused by: java.lang.NullPointerException

I don't have a log like AFTER RULE ADDED ... "dis". However Drools try to
remove "dis" when i execute another query after the exception have raised.
This is the last question. I promise!
