I tried the same thing but could not migrate cleanly. I dropped the plugin in the plugin directory and restarted eclipse. I see two Rule icons in my eclipse workspace. I closed it and deleted the 3.0.5plugin from the plugin directory but it still would not go away. Not sure how to get rid of it. -Krishnan. On 5/24/07, Ronald R.

Hi, I have a method in my code that creates a RuleBase, then adds a new WorkingMemory. I then put that that RuleBase into a Hashtable for later use. Another method receives a Fact along with a reference for an associated rulebase. One these are received, I get the rulebase from the hashtable, then use Set iterator to retrieve the working memory i originally created. At this point I would assert the fact into the retrieved WorkingMemory. However, i get a null pointer, that is, there is no WorkingMemory inside (returned by the Iterator) the RuleBase any longer. Any ideas what is going on? What is even more strange, when I step through the code in debug mode (MyEclipse), it works fine. Just doesn't work at normal runtime. Thanks, Alan J

Okay. In the meantime a simple workaround (for those that may find it useful) is to put the newly added WorkingMemory into a separate hashtable of WorkingMemories (sp?). WHen Facts come in, I just retrieve the appropriate workingMemory per the incoming identifier, assert the Fact and fire all rules. Have to hold two Hashtables, but as a short term fix it seems to work ok.
