[rules-users] Creating attributes of facts

[Amit Kumar]

Hi,


I need to create properties/attributes of a fact. Like today I am
checking for Color of a box. Tomorrow I want to Check Width also of a
Box.

Can I make this change just in the rule and attach it to some object
and pass it forward through the rule chain? I do not want to add Width
Attribute to Box.. as I will have to recompile the java files also in
that case.

I do not see this scenario in the documentaion. Where can I find
better examples.

Thanks,
Amit
