Hy. I have problems, filtering data with the help of /contains/. I have a HashMap with /long/-values as keys. In my rules I filter data in the following way: FilterCriteria(categories_slot1 contains $cid) HashMap categories_slot1 is initialized with HashMap<Long, Double>. $cid is set as long value in the corresponding class, too. Does this work in general? Second problem is that there is another HashMap with Strings as key values. FilterCriteria(brands contains $brand) The problem is, that /brands/-key value strings are not identical to $brand. But $brand can contain the key value string. But contains only checks if they are identical right? Thanks -- View this message in context: http://drools.46999.n3.nabble.com/2-problems-with-the-keyword-contains-in...

For second problem I think it should work with the /matches/-operator. I will test it...

First problem: I tested it with identical strings in HashMap and transaction data and it worked, so I thought only strings are allowed. I tried it with strings as key values and casting $cid to string in the way: ((String)$cid).toString()

But it says that it is unable to analyse this expression. -- View this message in context: http://drools.46999.n3.nabble.com/2-problems-with-the-keyword-contains-in...
