[rules-users] how to create local variable

[Edson Tirelli]

    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.
