Hi All; I was trying to use no-loop to avoid rule being triggered recursively. However for following rule, when there are more than one one object of type DataProduct, no-loop attribute has no effect. rule "Collect" no-loop true when q: Query(); buffer : java.util.Vector(); d: DataProduct(); then q.addDataProduct(d); update(q); end But on the other hand when there are only one object of type DataProduct in the system, the no-loop works. Is this expected behavior or have I uncovered a bug? Thanks Srinath
