[rules-users] facthandle iterator

Hi All, I thought this: public void retractFacts() { Iterator iter = workingMemory.iterateFactHandles(); while (iter.hasNext()) { FactHandle handle = iter.next(); workingMemory.retract(handle); } } would retract all facts, but in fact I get a compilation error because iter.next is an object, not a factHandle. How do I retract facts using an iterator iterating all facts? kind regards Christine
