[rules-users] re-fire all rules

Hi there, Is there a way to "reset" the working memory so that all the rules will run again when fireAllRules() is called? (I am running the startProcess method number of times with the same working memory) I know that normally rules will only be run again when there was a change and the fact was updated. but in my case I like to run all rules again in some situations without having a change on the facts. so is there a way to do this? Thanks Yaniv
