[rules-users] Pointer to working memory from within rule?

I'm converting from 4.0.7 to 5.0.1 and am getting errors on the previously working function below, (note this function is in the drl file): The error is: "Type mismacth: cannot convert from org.drools.QueryResults to org.drools.runtime.rule.QueryResults" I'm told we need to use the following class for queries in 5.0 and going forward: import org.drools.runtime.rule.QueryResults; import org.drools.runtime.rule.QueryResultsRow; The problem is getting a pointer to working memory from within a rule or function used to be done via the KnowledgerHelper object but that is not compatible with the new QueryResults class. What am I doing wrong? ------------------------------------------------------------------------------------------------------------------------------- function CardTransaction getCompletedTransaction (String cardnum, KnowledgeHelper khObj) { CardTransaction tranObj = null; String[] queryParams = {cardnum}; QueryResult result = null; final QueryResults results = khObj.getWorkingMemory().getQueryResults("GetCompletedTransaction", queryParams); for (Iterator<QueryResult> it = results.iterator(); it.hasNext(); ) { result = it.next(); tranObj = (CardTransaction)result.get("cardtransactionobj"); } if (tranObj != null) return tranObj; else return null; } Scott
