Hi, I encountered a problem when run rules, I modified the type of one attribute from Integer to Float of one fact type, but when call factType.newInstance(), it still created an instance with old type Integer, is it possible to reload it without refresh the whole knowledge base and session? The refresh will cost too many resources and I don't want this. -- View this message in context: http://drools.46999.n3.nabble.com/Is-it-possible-to-reload-the-definition...
