Yeah, but where would I put this @tpyesafe(true) thing, exactly? It seems that this is available with DRL declares only. So, what do I do with my pojo bean class?

declare also works to declare annotations for existings beans on your own classpath - as long you don't define any properties.

I'm trying to disable strictTyping for my MVEL rules, but I cannot figure out

KnowledgeBase, StatefulKnowledgeSession, etc. to run my rules.  I don't see
any methods where I can disable strictTyping or get the ParserContext, so
I'm out of ideas.

Can anyone point me in the right direction?
http://docs.jboss.org/drools/release/5.4.0.Beta2/knowledge-api-javadoc/org/drools/KnowledgeBaseConfiguration.html
And MVEL supports the following configurations:
  • drools.dialect.mvel.strict = <true|false>


However we would recommend instead that you don't use that configuration and instead use the @typesafe annotation on class declarations. So you relax just specific classes, rather than relaxing everything.
http://docs.jboss.org/drools/release/5.4.0.Beta2/drools-expert-docs/html_single/index.html

By default all type declarations are compiled with type safety enabled; @typesafe( false ) provides a means to override this behaviour by permitting a fall-back, to type unsafe evaluation where all constraints are generated as MVEL constraints and executed dynamically. This can be important when dealing with collections that do not have any generics or mixed type collections.



Thanks!
Joe
