Re: [rules-users] using "contains" against a List<BigInteger>

Hi, A newbie question I'm afraid. I've been unsuccessful searching the mailing-list archive (and google) for this. I'm trying to simplify rule-writing for Statistical Analysts to be able to write rules. I'm hoping to achieve this without resort to DSLR files and a DSL if possible as we currently need them for nothing else One of the situations I have is the following: -------------------- when $performance : Performance(         eval(calcScore.contains(BigInteger.valueOf(6))) ) then [...] -------------------- That works absolutely fine: CustAccPerf being a having several members, including an ArrayList<BigInteger> called calcScore Howwever I'd like to rewrite it like: -------------------- when $performance : Performance( calcScore contains 6 ) then [...] -------------------- Given the support for BigInteger & BigDecimal type comparison, and the structure of the 'contains' operator, I couldn't see why this wouldn't work. If someone could explain this would be excellent - for now I'm gong ahead with the eval, but from a non-technical usability POV the latter form would be far preferable: I'd prefer that the users don't have to worry about eval or BigInteger, and while I realize it's not possible (currently) to eliminate that altogether, I would like to eliminate as many of the (to quote) "meaningless tech stuff" questions as possible. Alternately if some kind person wants to tell me a better way of structuring that rule so I can use it as a template, then that'd be welcome also. Unfortunately we're dealing with a feed from a 3rd party system so restructuring the data is not a desirable option.
