I should note that hopefully you can limit this to something like $list : ODAList ( ) (a specific extends type of list where you could specify some criteria to be more specific with) or can assure that you only have one List in play at that time, or you're going to spend some execution going through every List in memory to check for these occurrences.

Argh...Sorry, wrong key too early...here's the full changes:

rule "Combine ODMAnswers"

when
$list : List( )
$a1:ODMAnswer( some check ) from $list
$a2:ODMAnswer( assuming something making this one different than $a1 ) from $list
then
$list.add(new ODMAnswer( ));
$list.remove($a1);
$list.remove($a2);
end

Try this;

rule "Combine ODMAnswers"

when
$a1:ODMAnswer( some check )
$a2:ODMAnswer( assuming something making this one different than $a1 )

eval(odmList contains $a1 && odmList contains $a2)
then
ODMAnswer answer = new ODMAnswer( );
odmList.add(answer);
odmList.remove($a1);
odmList.remove($a2);
