could you attach the process that you use? Reading the title of this issue looks like you are trying to add intermediate timer event instead of boundary event. They are represented by two different constructs in bpmn2. Boundary events must not have incoming connections as they are attached to another activity where intermediate events must have incoming connection.

Changing the summary to reflect the actual need from a customer.

'Add a Boundary Event to a Task' -> 'Add a Boundary Timer to a Task'

Toshiya Kobayashi <tkobayas> made a comment on jira JBPM-3971

Hi Maciej,

Yeah, attaching a Timer to an Activity (Task) is the actual requirement from customers. Currently (BRMS 5.3.1) we can attach a Timer Intermediate Event to an Embedded Sub-process (See attached BPMN2-TimerBoundaryEventInterrupting.bpmn2) but customers want to attach it directly to a Task.

Now I think the defaultPackage.newonboarding.bpmn2 is just a wrong process which was written by older Designer which simply generates <bpmn2:intermediateCatchEvent>. I wrote a simple process (defaultPackage.timerBoundaryExample.bpmn2) with BRMS 5.3.1 Designer which generates <bpmn2:boundaryEvent> if I drop a 'Timer Intermediate Event' onto a Task. Then I confirmed that it works with jBPM 5.4.0.Final.

I'm closing this ticket as 'Rejected'.

Thanks!
Toshiya

Attaching a correct test case

[Rewriting the description of this BZ]

Description of problem:

Platform BZ for https://issues.jboss.org/browse/JBPM-3319

Steps to Reproduce:
1. Add a Timer Intermediate Event to a Human Task with Web Designer
2. Export as bpmn file
3. Read the bpmn and build the KnowledgeBase

--> Attached jBPMEx70_timer_boundary_event_BRMS531.zip followed these steps.

Actual results:
