Yes, infact i expected both the conditions to work against the same object in the working memory? Is it not possible?

For this scenario, drools has not been allowing me to do a comparison amongst two attributes of the same class. When i do so, it complains of not being to resolve the variable.

Some thing like a1 > a2 does not work. I am forced to create a declaration and then use it to compare. If i do so, the run time thing fails.

How do i get around to compare two attributes from the same class. Something like

a1 > a2 or say a1 > (a2 * 1.5)

Thanks

You do understand that what you have there is a cross product, you'll need two objects to match against that - were you expecting this to wokr against and on the same single EMIAgainstProperty object?

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
