[rules-users] Some serious problems while authoring rules

I am facing some serious blocking issues while writing few rules. In the rule below, a1, a2 are Double objects. When i have the first statement in the rule " EMIAgainstProperty( obj : a1 )", the rule does not fire....when i comment and re phrase the second line as emi : EMIAgainstProperty( a2 >= ( * new* Double(10* 1.5 )) ), the rule is fired. Why is the first line making the rule not to fire. I have reported a similar problem yesterday, but could not find a resolution. On the other hand, i am unable to refer a1 directly to say a1.doubleValue() in the second line, it throws up and error. Any help??? What is the way out? * rule* "Test" *when* EMIAgainstProperty( obj : a1 ) emi : EMIAgainstProperty( a2 >= ( *new* Double(obj.doubleValue() * 1.5 )) ) *then * System.out.println(" Passed "); * end *
