In the BPMN 2.0 specification, conditional flow can be used without gateways. The JBoss Enterprise BRMS Process Designer supports this feature; however, knowledge bases will not build when processes include conditional flow in the process definition without using gateways.

Description Radovan Synek 2012-03-28 11:51:26 UTC
Conditional flow can be used without gateways (multiple outgoing connections from activity node, each with it's condition) by BPMN2 specification.

Guvnor BPMN designer supports this feature, but when you try to build knowledge base with this process definition, you get Exception - "This type of node cannot have more than one outgoing connection!"

Comment 2 Maciej Swiderski 2012-06-14 11:30:05 UTC
This was implemented on master (5.4.0-SNAPSHOT):
https://github.com/droolsjbpm/jbpm/commit/e19270b87d0faa7d1e5931a5cb674aa47f14d541
https://github.com/droolsjbpm/jbpm/commit/8f0c9db262ae5611d16159454d43cd091c668f0e

As recommendation is to use gateways this feature is by default disabled and can be enabled by configuring system property: -Djbpm.enable.multi.con=true
