Re: [rules-users] Some serious problems while authoring rules

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 Natraj On 7/19/07, *Mark Proctor* <mproctor(a)codehaus.org <mailto:mproctor@codehaus.org>> wrote: 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?
