Lets say I've got a Classroom, and a list of 4 students. And my rule is to not have Bill and Bob in the same classroom. I have a method Classroom.hasStudent(String name), which will say whether the room has Bill or Bob. But how do I call it??? Imagine this is my decision table: classroom: Classroom classroom.hasStudent("$param") Bob Bill How in the world do I get it to not say "no viable alternative at input "bob" for blah blah blah"? I've also tried classroom.hasStudent("$param") == true with no success. Please help, Thank you...

You need to import the function. for example, import YourOtherClass import function Classroom.hasStudent ----- Original Message ---- From: djb <dbrownell83(a)hotmail.com&gt; To: rules-users(a)lists.jboss.org Sent: Fri, January 8, 2010 8:30:20 AM Subject: [rules-users] Decision table accessing my own methods Hi there, I have been trying for hours now to get a decision table that can call my own methods.

The most likely reason for this is that your rule action goes and updates classroom which then causes the rule to be evaluated and matched again. > -----Original Message----- > From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users- > bounces(a)lists.jboss.org] On Behalf Of djb > Sent: 11 January 2010 10:21 > To: rules-users(a)lists.jboss.org > Subject: Re: [rules-users] Decision table accessing my own methods > > > Ok, solved it. eval(classroom.hasStudent("$param")).
