Combine standard task (ABAP method call) and additional UWL Action Handlers

Question

Hi, i have defined a task with an asynchronous ABAP method call and a terminating event which i want to use "as is" in the universal worklist, that means that the standard action has to be the ABAP method call defined for the task.
In addition to that i want to add an extra button to the workitem view in the worklist which opens a web dynpro application. The web dynpro needs a parameter from the workitem container. Opening the web dynpro is not required for completing the task, so i do not consider using secondary methods.
I created an UWLConfiguration for the task type without defining the defaultAction attribute, since defaultAction should not be overwritten. I wanted to use SAPWebDynproABAPLauncher to generate the button since i can easily include values from the workitem container in the call.
When executing a workitem from the worklist the ABAP method call is not performed, instead a window opens which just displays the workitem. The button to web dynpro is generated and works fine.
Does anyone have a clue how i can use UWL to define an additional button with SAPWebDynproABAPLauncher without overwriting the standard task definition?
My definition:
<ItemTypes>
    <ItemType
name="uwl.task.webflow.TS95100103"
connector="WebFlowConnector"
defaultView="DefaultView">
      <ItemTypeCriteria

        </CustomAttributeSource>
      </CustomAttributes>
      <Actions>
        <Action

            <Property

            <Property

            <Property

            <Property

            <Property

          </Properties>
          <Descriptions default="Show"/>
        </Action>
      </Actions>
    </ItemType>
  </ItemTypes>
Thank you very much, best regards, Martin
