[rules-users] Dynamic JavaBeans

I noticed that changes performed on facts asserted dynamically causes the fact to be modified right away and therefore triggering a RETE network traversal and rule schedulings. For apps with a large number of facts this could be a significant scalability problem. At least in my case, I would like to be able to use dynamic facts and perform any number of updates and have those updates commited to working memory only when the rule consequence is completed. Looking at the code, it seems that it would not be a major effort to collect the facts received by the ReteooWorkingMemory.propertyChange and perform the actual modifyObject() only when the consequence evaluation is actually completed. Does that makes sense? Or are there side effects I am not seeing? Is this a problem that 4.0 already resolves? thanks in advance, -- yuri
