How to get activiti:field name from a service Task

zaridak — Thu, 26 Jul 2018 18:35:07 GMT

Hello all,I would like your help whether there is a way to get from a java class the "activiti:field name" from a service Task and not only the value. For instance if we have this service task:<serviceTask id="servicetask1" name="Service Task" activiti:class="Test"> <extensionElements&

Inside the execute method you can try this:

// in version 5x you can get the repositoryService using
// execution.getEngineServices().getRepositoryService()
BpmnModel model = repositoryService.getBpmnModel(execution.getProcessDefinitionId());
FlowElement flowElement = model.getFlowElement(execution.getCurrentActivityId());
List<FieldExtension> fieldExtensions = ((TaskWithFieldExtensions) flowElement).getFieldExtensions();
// loop through the list to get field extension with name you want fieldExtension.getFieldName()
// if only one extension field then should be the first element

Hope that helps.

Hello,

Thank you for the replay and yes it was indeed helpful! Furthermore, in case that someone else need it, it also works outside the execute method and even in another class like this:

FlowElement ServiceTaskName = getServiceTask(); // custom method to get Service Tasks from the repositoryService and //Bpmn model

FlowElement flowElement = model.getFlowElement(ServiceTaskName.getId());

List<FieldExtension> fieldExtensions = ((TaskWithFieldExtensions) flowElement).getFieldExtensions();
System.out.println("Extension name: "+fieldExtensions.get(0).getFieldName());//if only contains 1 element

Thanks again,

Alexander.
