Re: [rules-users] [rule-users]how to create object properties in single stmnt

Hi , The very reason i used to compare two object reference is that i got then executed multiple time when i do duplicate check between object properties. so i beleive the pattern match happen more than a time for example when $obj1:object($code:code,$stdate:startdate); $obj2:object(code==$code,startdate=$stdate); then if(obj1!=obj2) System.out.println("Fired"); My questions are 1) In 3.0.6 is there any other way to avoid this multiple check other than using eval(which affects performance i beleive). i can't use this operator in 3.0.6 2) related to this i have one more query. how to check properties within the object itself for example i want to do when $obj1:object($code:code,$stdate:startdate,$enddate:enddate > $stdate, reasoncode == $code); then System.out.println("Fired"); i beleive the above throws error in 3.0.6 (nullpointer related to alpha node) Earlier reply is highly appreciated Thanks and Regs, Bassha ---------------------------------------------------------------------- Message: 1 Date: Fri, 18 May 2007 09:51:34 -0300 From: "Edson Tirelli" <tirelli(a)post.com&gt; Subject: Re: [rules-users] how to check reference To: "Rules Users List" <rules-users(a)lists.jboss.org&gt; Message-ID: <e6dd5ba30705180551y6562b7f6oe5ea173379ebb4c8(a)mail.gmail.com&gt; Content-Type: text/plain; charset="iso-8859-1" Yes, in 3.0.6 you will need eval. But also it is important to remember that by default, in 3.0.6, an object will never match more than one pattern. So in the given example, ob1 and ob2 will always be different and the check is not needed. In 4.0, things are a bit different, as by default a single object may match more than one pattern at once and we introduced the "this" keyword to check for object identity.
