> I have tried to create a minimal test case that recreates this issue, here it is:
> package indexingproblem.remove.me.anditworks;
> declare Criteria
>   processed : boolean
> end
> declare CheeseCriteria extends Criteria
> end
> rule setUp
> salience 10000
> 	when
> 	
> 	then
>         insert(new CheeseCriteria());
> end
> rule aaa
>   when
>         CheeseCriteria(  ) 
>   then  
> end
> rule bbb
>   when
>         CheeseCriteria( )
>   then   
> end
> rule ccc
>   when
>         CheeseCriteria(  )
>   then  
> end
> rule eeeFalse
>   when
>         Criteria( processed == false )
>     then
> end
> declare Filter
>   
> end
> rule fffTrue
>   when
>         Criteria( processed == true )
>         Filter(  )
>     then
>         
> end
> rule ruleThatFails
>   when
>         $criteria : Criteria( processed == false )
>     then
>         modify($criteria) {
>             setProcessed(true)
>         }
> end
> This is working fine with 5.3.0.Final. But it is failing with 5.4.0.Final and also 5.5.0-SNAPSHOT. Note that if you change the rule package to be "package indexingproblem" the exception is not thrown. The code for building the KnowledgeBase is standard, I haven't used any additional options. No fact is inserted only one fireAllRules call.
> Thanking you.
