Get UserTask propery in java API

Camunda 7 Topics Discussion & Questions
1

I have this as part of my bpmn:userTask deff:

  <bpmn:extensionElements>
    <camunda:properties>
      <camunda:property name="myProperty" value="0" />
    </camunda:properties>
  </bpmn:extensionElements>

I have an instanceId and a taskId. How, through the java API, do I get the value?

We use something like this:

    String taskId = ...;
    ProcessEngineServices processEngineServices = ...;
    Task task = processEngineServices.getTaskService().createTaskQuery().taskId(taskId).singleResult();
    String taskDefinitionKey = task.getTaskDefinitionKey();
    String processDefinitionId = task.getProcessDefinitionId();
    Optional<String> myPropertyValue = processEngineServices
            .getRepositoryService()
            .getBpmnModelInstance(processDefinitionId)
            .getModelElementsByType(UserTask.class)
            .stream()
            .filter(userTask -> userTask.getId().equals(taskDefinitionKey))
            .map(UserTask::getExtensionElements)
            .filter(Objects::nonNull)
            .flatMap(e -> e.getElementsQuery().filterByType(CamundaProperties.class).list().stream())
            .flatMap(e -> e.getCamundaProperties().stream())
            .filter(e -> e.getCamundaName().equals("myProperty"))
            .map(CamundaProperty::getCamundaValue)
            .findAny();

Would I have to go through the BpmnModelInstance to get something at the process level as well?

I have this:

  <bpmn:process id="ny_process" name="My Process" isExecutable="true">
    <bpmn:extensionElements>
      <camunda:properties>
    <camunda:property name="someProperty" value="someValue" />
   </camunda:properties>
  </bpmn:extensionElements>

I would like to get the “someProperty” value. How would I do that?

@mmaceachran yes, just .getModelElementsByType(Process.class)
