You'll have to add the information that isn't available with an anonymous fact object, i.e., a name tied to a reference. class NameFact { String name; Object fact; ... } To identify any fact that hasn't an id in its contents: (a) via a name when NameFact( name == "Chebyshev", $fact: fact ) List( this == $fact,... ) (b) via the fact when $list: List( size == 0 ) NameFact( $name: name, fact == $list ) then x.println( $name + " is empty" ); -W On 27/11/2012, abhinay_agarwal <abhinay_agarwal(a)infosys.com&gt; wrote:

"I can make a class with attributes as Name, List and insert three different objects of the class, with three different names." That is exactly what Wolfgang said.

Well, there could be another way using one global for each of your lists (the lists should be inserted as fact just like you are doing) and then doing something like List( this == globalListA), but I never tried something like that. I think Wolfgang's recommendation (which is the same you have proposed) is the most elegant solution.

Are the values in the list ever tested? (With rules conditionally firing if the contents of a list changes.)  In the rules you've provided so far they are not.  If this is the case then there's no need to match them in the conditions and the use of globals is just fine.  The only reason to match a list in the rule conditions is if changing the list could result in that rule firing. ________________________________ From: abhinay_agarwal <abhinay_agarwal(a)infosys.com&gt; To: rules-users(a)lists.jboss.org Sent: Tuesday, November 27, 2012 4:36 AM Subject: Re: [rules-users] Inserting Different Objects Of Same Class ! I was initially using two lists making them global, and it was working for me, but then i read "Globals are not designed to share data between rules and they should never be used for that purpose. Rules always reason and react to the working memory state, so if you want to pass data from rule to rule, assert the data as facts into the working memory." So, thought might be somewhere, an issue can arise and changed the global facts.
