How to get activiti:field name from a service Task

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>
        <activiti:field name="theName" stringValue="test value"/>
      </extensionElements>
    </serviceTask>

And on the other hand: 

    class Test {              

             org.activiti.engine.delegate.Expression theName;

             @Override
             public void execute(DelegateExecution execution) throws Exception {       

             String value1 = (String) theName.getValue(execution);

             //now value1 contains the string: "test value"

  }

Can I somehow get the activiti:field name(="theName") (maybe from the bpmn file) without the need of declaring  "Expression theName in the class??

Thanks in Advance,

Alexander.

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.
