RE: [rules-users] how to create local variable

Thank you Edson, I liked the solution with matches, it is much cleaner.... -Sergey ________________________________ From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Edson Tirelli Sent: Thursday, July 12, 2007 4:19 PM To: Rules Users List 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. []s Edson 2007/7/12, Manukyan, Sergey < SManukyan(a)lear.com&gt;: 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 ********************** ** LEGAL DISCLAIMER ** ********************** This E-mail message and any attachments may contain legally privileged, confidential or proprietary information.
