Folks,

 

I am using MR3, have a situation when Parent has multiple Children, and there is a rule that needs to be fired when parent has a child with certain attribute (active == true)

 

Will need to do something like that :

 

rule

      when

     $p : Parent( active == false,  children contains Child() [ active == true  ] )

      then

                 … register error: inactive parent cannot have active child.

end

 

 

Please advice on correct syntaxes how to do that. Also please keep in mind, I don’t want to insert children in facts memory.

 

Thanks,
