[rules-users] Reg. Iterating over a list

[Phani Saripalli]

Hi

Thank you very much I partly succeeded using your suggestion. 

I particularly did the following: 

rule "list rule "
agenda-group "Group 2"
dialect "mvel"
no-loop true
 	when
 		P : Project(isDefined(P.seq_B))
 		s : java.util.ArrayList() from collect ( Integer (!(this > 0 && this <
3)) from P.seq_A)
 				
 		 //( Integer (this > 0 && this < 3) from P.seq_A);
 	then		
 		System.out.println("Rule satisfied # " + P.seq_A);
 		
 		//modify(P) {seq_B = s};	
end	

However, I would like to do every thing all at once in the LHS, or maybe
RHS. This is because I have to work around similar functions like the
following:

1) collect from collectionA with a boolean constraint into collectionB
2 ) similarly, collect everything that does not satisfy.  

Custom evaluators  - sounds interesting. Sadly, I did not find it. Would be
very much useful if you can share an example.

Many thanks :)
