Fact Not Found in Rule engine working memory

Question

I am using 11g, I have built a Business Rule, using RL facts, XML facts, Bucketsets and multiple Rulesets which internally has decision table and If-then rules. After deploying the same, Business rules runs successfully for some conditions and faults for some condition. The fault error for those failed conditions displays the following error:
Fact not found in the rule engine working memory, rule session execution failed. The rule session bpel:<somenumber> failed because an instance of the fact <factname> could not be found in the working memory of the rule session. This is most likely a rule modeling error. The decision service interaction expects the fact instance to exist in the working memory of the rule session. Check the rule actions in rule designer and make sure that a fact of the expected type is being asserted. Contact oracle support if error is not fixable.
It is wierd becuase if it is a fault with respect to working memory then I would imagine it has to fail for all the conditions as all the conditions assert the same Object. Has anyone faced the same issue or am I doing something wrong here.

I deleted the RL facts that I had created and asserted the result to the Business Object, this seems to have taken care of this issue, but I am still not sure what was wrong in the way I build the rules using RL.Hope this helps.
