Thank you Edson,

I liked the solution with matches, it is much cleaner….

Subject: Re: [rules-users] how to create local variable

    It is not possible to assign the result of an arbitrary method call to a variable right now. So, your best option is probably to do (please note the use of inline-eval):

rule "SupplierView: Headquarter Supplier Code should end on 25 or 30."

when

            $cs : SupplierView(corporate == true, eval( suppCode.substring(4, 6).equals( "25" ) || suppCode.substring(4, 6).equals( "30" ) ) )

then

            ValidationErrorFacade.getInstance().registerError($cs, new ValidationError("Headquarter Supplier Code should end on 25 or 30."));

end

    A more clean solution is to use "matches" operator. If your rule states that Supplier Code must END with 25 or 30, you can do:

rule "SupplierView: Headquarter Supplier Code should end on 25 or 30."

when

            $cs : SupplierView(corporate == true, suppCode matches ".*25" || matches ".*30" )

then

            ValidationErrorFacade.getInstance().registerError($cs, new ValidationError("Headquarter Supplier Code should end on 25 or 30."));

end

    Hope it helps.

Folks,

I have a rule where I am repeating part of it twice : ($cs.getSuppCode().substring(4, 6)), and I would like to replace it with variable… how can I do that? The solution with "in" doesn't worl because it is a java code needed to perform calculations for variable…..

Please see the rule below:

rule "SupplierView: Headquarter Supplier Code should end on 25 or 30."

when

            $cs : SupplierView(corporate == true)

eval($cs.getSuppCode().substring(4, 6) == "25" || $cs.getSuppCode().substring(4, 6) == "30")

then

            ValidationErrorFacade.getInstance().registerError($cs, new ValidationError("Headquarter Supplier Code should end on 25 or 30."));

end

Thanks,

-Sergey
