Esteban,

   That is not correct. Drools allows for dynamic addition/removal of assets and properly update existing sessions to reflect that.

   As I explained in the IRC:

<etirelli> dranelf: the problem is not "firing" the rules, but the fact that the LHS of the rules is evaluated immediatelly after they are added to the kbase
<etirelli> dranelf: you will need to define and set your global before loading those rules
<etirelli> just use a separate DRL file that may contain only the global definition
<etirelli> load it, set the global and then after that load the actual rules

I think that if you modify the kbase, you must recreate all your sessions. You can't use any session created previous the kbase modification.

Best,

I'm trying to add rules after the Process (workflow) started. That works, but
I wanted the rules to access database data using hibernate.

So I created a global object to store my EntityManager (I'm using SEAM; it's
like a Session object).

The problem is that when I add the KnowledgePackage with the rule that uses
the EntityManager, an exception is thrown because the global is not set.
BUT, if I try to set the global var, I get an exception saying it does not
exist.

Do you have any idea?

I've seen that when I add the KnowledgePackage to the
StatefullKnowledgeSession the rules are fired, and then I get the exception.
Is there a way to NOT fire the rules after inserting the packages?
