Re: [rules-users] Updating an existing fact w/o using fact handle

Is it required to use WorkingMemory.update to update an existing fact? I thought if assert behavior was set to equality and you implemented the equals method properly, then you could simply use WorkingMemory.insert to overwrite a fact in working memory with a new version. If this isn't the case, then are there other settings that will give this behavior? I'm using 4.0.7. Thanks for any help.
