Re: [rules-users] Tuples in Agenda Item.

Regarding Issue 1: Even if you do have different objects of ConcreteType1, the rule is fired for each of them, since each of these is equal to itself in terms of the BaseType. I also fail to understand Issue 2. But perhaps your misconception about base type and subtype matching is also responsible for that. Rule "s" looks strange for more than one reason. What is the DroolsWorkingMemory() pattern supposed to achieve? Is it a general trigger so that the rule only fires if one such object is present? Leaving base and extended types aside, testing for the equality of two objects of the same type must be done much more carefully. Assuming three objects of TypeX, x1, x2, x3 with x1.equals(x2) and NOT x1.equals(x3) and a rule like this: rule "xxx" when o1 : TypeX() o2 : TypeX() eval( o1.equals( o2 ) ) then ... This rule will fire 5 times, with the following activations: <x1,x1>, <x2,x2>, <x3,x3>, <x1,x2>, <x2,x1>. Using, e.g., o2:TypeX( this != o1 ) reduces this to two firings. -W 2010/4/9 Rajnikant Gupta <capricorn.raj(a)gmail.com&gt; Hi, > ** > Sorry for not being very clear.
