[rules-users] Initialize Global

[Anstis, Michael (M.)]

Did you try Kris's suggested LHS?

This should provide the condition you request and prevent the rule from
firing after the global has been initialised.

Hi Kris,

I am using a JSR94 stateful session.  My design is to initialize the global
list once and reuse it within the same session.  

The init-global rule is being executed each execution because there is no
conditional statement.  Can I disable the rule for future executions?

Thanks
