[rules-users] using a fact from within a List<FactType> in a Guided Decision Table in Guvnor

Hi ,   Can I use a field from a fact from within a List<FactType>  in a Guided decision Table as a condition column ?   We have a List<Asset> being inserted into rulesession.   We would like to use a field from within a Asset  in the List<Asset> as a condition column in a guided decision table in Guvnor.   Can we do that? Or do we need to insert each of the Asset into rulesession ?   One reason we would like to insert  List<Asset> is to be able to do some calculations such as counting number of assets in memory. perhaps , this can be done even at an Asset level, but I have not tried the count rule   Thanks,   Ram
