[rules-users] How do I assign a value to a variable using a method call.

Hello, I'm very new to drools and am trying to do something like the following: rule "test" when $x: X( ); $y: Y( ) from someAction.getY( x.getId() ); eval( hasSomethingChanged( $x, $y ) ); then $x.warnSombody("some message"); end The problem is when I load the rule it gives me an error when it hits the from line. [testng] FAILED CONFIGURATION: @BeforeClass setUp("/test.drl") [testng] org.drools.rule.InvalidRulePackage: Unable to build expression for 'from' node 'someAction.getY( x.getId() )' : [Rule name=test, agendaGroup=MA IN, salience=0, no-loop=false] I'm a bit stuck on this so any help would be great. -- View this message in context: http://www.nabble.com/How-do-I-assign-a-value-to-a-variable-using-a-metho...
