Summary: Multiple incoming/outgoing sequence flows to/from activities cause the build to fail in the Designer even though the process passes validation. This is caused by the lack of a system property in the Designer. In a future release, a process with multiple flows will fail validation as the validation errors from core engine will be added to the Designer validation process.
Cause: Build a valid BPMN2 process in Designer with multiple flows and from multiple activities. Validate and try to create a build.
Consequence: Validation passes, but the build fails.
Workaround: None at this stage. Expected Fix in ER5.
Result: Designer will not allow the user to build a process with multiple flows from multiple activities.
