Hi, after creating the standard RuleFlow example with Drools 5 in Eclipse, adding a gateway with two (true) constraints leads to the following error "org.drools.compiler.RuleFlowLoadError: Unable to load the rule flow. : Exception class org.xml.sax.SAXParseException : <constraint> requires a 'toType' attribute". This seems to be a very basic serious problem. Here is my RuleFlow file in which I only added one split node and a trivial output action. <?xml version="1.0" encoding="UTF-8"?> <process xmlns="http://drools.org/drools-5.0/process" xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" xs:schemaLocation="http://drools.org/drools-5.0/process drools-processes-5.0.xsd<http://drools.org/drools-5.0/process%0Adrools...

It's weird that it doesn't work if you don't put that.. that must be the default value..
