You could try assigning $item to a local variable and then using that within the for loop?
Thomas From: rules-users-boun...@lists.jboss.org [mailto:rules-users-boun...@lists.jboss.org] On Behalf Of Martin A Sent: 11 January 2012 10:02 To: Rules Users List Subject: Re: [rules-users] For loop inside a modify block problem hi Michael, All of the fields are public, however they are properties of a super class of Item. I tried with getters, doesn't work either way. Still getting: 'no such identifier : $item'. When I remove the for loop, it goes ok, so I think it messes up things. Best regards, Martin 2012/1/11 Michael Anstis <michael.ans...@gmail.com<mailto:michael.ans...@gmail.com>> RHS is not DRL syntax but Java or MVEL depending on your dialect. If "id" is not public you should use it's getter. The same goes for "quantity". when $item : Item(param1 != 0, param2 == 0, !(this instanceof SpecialItem)) $gsc : SomeBusinessLogic then $gsc.doSomething($item.getId() ); for (int i = 0; i < $item.getQuantity(); i++) { $gsc.doSomethingElse($item.getId() ); } update($gsc); end 2012/1/11 Martin A <wml...@gmail.com<mailto:wml...@gmail.com>> Hi, Davide, Here is how my rule looks like : when $item : Item(param1 != 0, param2 == 0, !(this instanceof SpecialItem)) $gsc : SomeBusinessLogic then $gsc.doSomething($item.id<http://item.id/>); for (int i = 0; i < $item.quantity; i++) { $gsc.doSomethingElse($item.id<http://item.id/>); } update($gsc); end The above snippet throws an error @ i < $item.quantity, and says 'no such identifier $item'... I can't figure out what might be causing this.

Maybe you just called that "item" without the $ :) Davide (the original "modify" syntax is still wrong anyway) -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-For-loop-inside-a-modify-block-problem-tp3648460p3648718.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org<mailto:rules-users@lists.jboss.org> https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users@lists.jboss.org<mailto:rules-users@lists.jboss.org> https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users@lists.jboss.org<mailto:rules-users@lists.jboss.org> https://lists.jboss.org/mailman/listinfo/rules-users ________________________________ ************************************************************************************** This message is confidential and intended only for the addressee.
