[rules-users] RuleFlows and Working Memory..

Hi there, I have got a couple of questions about ruleflows and woking memory. What does happen each time I modify a fact within a ruleflow node without calling update(fact)? What does happen between the node where I apllied the modifications and the next activation node? I guess that between one ruleflow node and the next one, all the modified facts (in the previous node) are automatically updated (without explicitly call "update()") so that once the next node has been activated, the corresponding shadow facts result synchronized with the actual facts. Am I wrong? Should I call "update()" instead? My scenario... I have got one node where I modify a fact, but I do not want to call the update() because otherwise I would generate a "ping-pong" loop between two decision tables that are placed in the same rule flow node. I think I could use the "no-active" attribute but I can't.... cause I can't specify it in a Decision table. Another workaround could be the "clearAgenda()" method but It is not accesible from the "drools" (the helper) object... How can I call it from the decision table or within an "action" ruleflow node? Maybe there is a third solution.... I should "update()" all the fact from an action node ...but in this case I would need to call an "update()" method that allowed me to update "all the facts of a given Class", Is That Possible in drools? I took a look on the API docs but some methods are not explained. Looking forward to hearing from you! Thank You again! Massi
