Created attachment 567907 [details] process definition Description of problem: There are 3 options how to specify timer - duration, cycle and date. One of them should be filled in (see XSD - timerEventDefinition: http://www.omg.org/spec/BPMN/20100501/Semantic.xsd). But not all of them. Steps to Reproduce: 1. Start the Guvnor, create new BPMN2 process. 2. Choose "Import from BPMN2" in BPMN designer and load attached definition. 3. Click on Validate Process button. 4. There is validation error over timer saying that timecycle and timedate are missing.
Fixed and checked into master and the 2.1.x branch.
