Hi guys, I've been desperately trying to update a Boolean object, which is in the working memory. I have an initial rule that  first inserts it: rule "Insert initial weanable value" salience 100        when        then                Boolean $weanable = false;                insert($weanable); end and then I try to update it:       ...       when               $weanable: Boolean( )               ...       then                $weanable=true;                update($weanable); end Which results to this exception : org.drools.FactException: Update error: handle not found for object: true. Is it in the working memory? I checked in the working memory and the Boolean-object was there! Is it possible to update a boolean that is in the working memory? If not, do you know some other Java class with setters and getters (behaving as a drools-fact) that I don't have to create myself and which I can use instead of Bboolean for this case ? Thanks in advance! Svetlomir -- View this message in context: http://www.nabble.com/Updating-a-Boolean-object-in-the-WM-tp24513225p2451...
