Noob alert, first post. I have a rule that works fine when I run it in a JUnit test. I've imported it into Guvnor (along with all my referenced pojos and functions) and it will not build there. Here is the error: Unable to Analyse Expression for (String curr : (List<String>) $validList) { ValidValue aValidVal = new ValidValue(curr); drools.insert(aValidVal); }; for (int i=0; i<$validList.size(); i++) { String curr = (String)$validList.get(i); ValidValue aValidVal = new ValidValue(curr); drools.insert(aValidVal); };: [Error: unexpected token: $validList] [Near : {... rr : (List<String>) $validList) { ....}] ^ [Line: 1, Column: 35] What the rules is trying to do is run values from a set of records through a validation function and then add each of the valid values as individual facts. Guvnor apparently doesn't like the way the iteration of the list is being done. I've tried a few different ways of iteration. Thanks in advance for any advice. Here is the rule: when $validList : List() from accumulate( InRecord($value : value != ""), ListValid($value)) then for (String curr : (List<String>) $validList) { ValidValue aValidVal = new ValidValue(curr); insert(aValidVal); } for (int i=0; i<$validList.size(); i++) { String curr = (String)$validList.get(i); ValidValue aValidVal = new ValidValue(curr); insert(aValidVal); } Regards, John Perrin *************************************************************************** The information contained in this communication is confidential, is intended only for the use of the recipient named above, and may be legally privileged.
