Custom Column in UWL

Hi friends,

I want to display a custom column(Workitemid) in UWL. The data for the column will be coming from the webflow container. The workitemid is a field in the structure WORKITEM. I am able to access the structure(WORKITEM) directly but not the fields within the structure. Can someone please help me in this regard.

The xml code where I am able to access the WORKITEM structure is as follows:

<ItemType name="uwl.task.webflow.TS14508044.RUI_GEE" connector="WebFlowConnector" defaultView="Approved_WorkItems" defaultAction="launchWebDynPro" executionMode="default">

<ItemTypeCriteria systemId="RUI_GEE" externalType="TS14508044" connector="WebFlowConnector"/>

<CustomAttributes>

<CustomAttributeSource id="WEBFLOW_CONTAINER" objectIdHolder="externalID" objectType="WORKINGWI:BO::u:0:0" cacheValidity="final">

<Attribute name="_WORKITEM" type="string" displayName="Workitem"/>

</CustomAttributeSource>

</CustomAttributes>

.
