My Question is

How Can I Check This Error and Fixed this problem ?

Niall · June 2, 2018, 9:11am

can you upload the BPMN file itself?

pingkungw · June 2, 2018, 9:19am

@Niall this is my bpmn file
testTimer.bpmn (3.9 KB)

I think. Duedate is null, Its may be relate to xml configuration in https://app.camunda.com/jira/browse/CAM-4135

 <properties>
  <property name="jobExecutorDeploymentAware">...</property>
  <property name="jobExecutorPreferTimerJobs">...</property>
  <property name="jobExecutorAcquireByDueDate">...</property>  <<= What Place can I add this config
  <property name="jobExecutorAcquireByPriority">...</property>
</properties>

where can i set these xml config in Camunda BPMN Engine & Unit Test Project

My English Skill is not good , Sorry T__T

It looks like the problem is with the timer’s implementation.
I think you’ve incorrectly used the ISO8601. How often do you intend to have this process start?

pingkungw · June 2, 2018, 9:33am

this is my ISO8601 in bpmn:timerEventDefinition >> bpmn:timeCycle

<bpmn:startEvent id="StartEvent_1">
  <bpmn:outgoing>SequenceFlow_18slmhg</bpmn:outgoing>
  <bpmn:timerEventDefinition>
    <bpmn:timeCycle xsi:type="bpmn:tFormalExpression">R4/2018-06-02T12:13/PT5M</bpmn:timeCycle>
  </bpmn:timerEventDefinition>
</bpmn:startEvent>

Start 4 times in 5 minute on 2018-06-02 at 12:13

Niall · June 2, 2018, 9:36am

I don’t think we support that particular function with ISO8601 - you could try a CRON time instead that might be better.

pingkungw · June 2, 2018, 9:39am

It mean this online documentation https://docs.camunda.org/manual/7.8/reference/bpmn20/events/timer-events/ is incorrent ?

Niall · June 2, 2018, 9:41am

Good point - We should support that, I’ll look into that now and try to figure out what that error is all about.

Niall · June 2, 2018, 9:48am

I think i got it now - the date you set in the BPMN model you uploaded was in the past.

If you add a data in the past it won’t deploy it so if you add the below to your model and try to deploy it - it should work

It worked when I deployed it anyway.

pingkungw · June 2, 2018, 2:54pm

Great , It’s work

I have next one question - when i test bpmn on UAT Enviroment / how to change time on Camunda BPMN to The Past time and My UAT Enviroment , I cannot change OS time because there ara another system that deployed.

Can I change Camunda BPMN system time vis rest api

Thank
