I have the next xml of my bpmn task where I am trying that the loopcounter be variable (watch the line <loopCardinality>${loopCounter}</loopCardinality> ) And This variable is part of the start event form. <startEvent id="startevent1" name="Start"> <extensionElements&g

Hi,

Can you create jUnit test please?

Where is the new jira linkg, the link that is posted by Joe Barrez is deprecated (codehouse servicess are not enable).
I have the zip file but I do not know where to upload it due to this page does not support it.
When I tried to run the unit test, there this error message, even when the xml has been deployed in the activiti explorer without problems:
<code>
Unknown property used in expression: ${loopCounter}
</code>
See the full trace in the attached file.

I have created the jira ticket with the jUnit test https://activiti.atlassian.net/browse/ACT-4173

Hi kecondezo,

The issue is loopCounter is reserved key word by default (see doc). You have two options:
- rename loop variable
- change default loop variable name.

If I changed test to:


 public void test() {
  Date date = new Date();
  Map<String, Object> variables = new HashMap<String, Object>();
  variables.put("customerName", "Calimba");
  variables.put("customerEmail",
  "kecondezo@gmail.com");
  variables.put("trainingTopic", "Activiti");
  variables.put("trainingDate", date);
  variables.put("trainerName", "Kennyman");
  variables.put("trainerMailId","kecondezo@gmail.com");
  variables.put("loopC",5);
  //ProcessInstance processInstance = activitiRule.getRuntimeService().startProcessInstanceByKey("my-process");
  ProcessInstance processInstance = activitiRule.getRuntimeService().startProcessInstanceByKey("trainingProcess", variables);
  assertNotNull(processInstance);

  Task task = activitiRule.getTaskService().createTaskQuery().singleResult();
  assertEquals("Business Development Executive", task.getName());
 }

and process definition:


      <multiInstanceLoopCharacteristics isSequential="true">
        <loopCardinality>${loopC}</loopCardinality>
      </multiInstanceLoopCharacteristics>

The test has passed.

Martin

Thanks Martin,
I change the name of the variable for loopC, in the JUnit test I am still getting the same message
<code> Unknown property used in expression: ${loopC} </code>
but when I tried the change directly into Activity Explorer it works fine.
So can you attach your project into Jira to see what is wrong with my JUnit environment?. This is not the first time the JUnit thorows this error and the model works fine in the Activiti Explorer.

Hi,

I think you missed this line in the jUNit test:


ProcessInstance processInstance = activitiRule.getRuntimeService().startProcessInstanceByKey("trainingProcess", variables);
