[rules-users] Cannot retrieve an existing WorkingMemory fromRuleBase

[Jones, Alan R]

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.
 

Thanks, 

Alan J

   Seems like a hashcode() problem... can you get a self contained test
case and open a JIRA for it?

	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
