Hi all, Is there a migration guide from 4.0 MR2 to 4.0 GA ?. I had got the code working in 4.0 MR2 and thought it would be as easy as just changing the jars. But it is not. Many things have changed. (a) I modified the assert() into insert() Is there anything else I should know about ? One of my failure is for the method clearAgenda() is undefined for the type KnowledgeHelper. Previously, in the rules file (.drl), once a rule has executed and I know I am done, I would call drools.clearAgenda() to expedite the processing, this does not work anymore. Has the functionality changed ? Any help will be appreciated ?. thanks, Krishnan. -- Sivaramakrishna Iyer Krishnan (Anand) Never assume the obvious is true. - William Safire _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Hi Edson, Thanks for your suggestions. The facts are produced as the rules are executed. Once the "interesting" fact has been produced which involves a rule to be executed, I am done but this does not mean the production of facts is done. So, I used clearAgenda(). Also, I use a new workingmemory for every new thread (multi-threaded environment). So, if I use halt() is this equivalent to clearAgenda() ?. From my understanding, the execution starts again only if you use the same working memory ?. Thanks, Krishnan.
