URGENT: Workitem ID not passed through UWL

Hi All,

We are using custom task for leave approval application and i have modified the com.sap.pct.erp.mss.addon.xml as per the sap note: 1600953.

I could successfully upload the new configuration and cleared the cache after upload.

Below is the new code as suggested by the sap note

<ItemType name="uwl.task.webflow.TS91000073.SAP_ECC_UWL_200" connector="WebFlowConnector" defaultView="DefaultView" defaultAction="defaultAction" executionMode="default">
      <ItemTypeCriteria systemId="SAP_ECC_UWL_200" externalType=" TS91000073" connector="WebFlowConnector"/>
<CustomAttributes>
        <CustomAttributeSource id="WEBFLOW_CONTAINER" objectIdHolder="externalObjectId" objectType="WebflowContainer" cacheValidity="final">
          <Attribute name="REQUESTID" type="string" displayName="Request ID"/>
        </CustomAttributeSource>
      </CustomAttributes>
      <Actions>
        <Action name="defaultAction" groupAction="" handler="ObjectNavigationLauncher" returnToDetailViewAllowed="yes" launchInNewWindow="yes">
          <Properties>
            <Property name="Operation" value="approveleaverequest"/>
<Property name="ObjectValue" value="LRF_REQUEST_ID=${item.REQUESTID}" />
           <Property name="DynamicParameter" value="LRF_REQUEST_ID=${item.REQUESTID}"/>
            <Property name="openInNewWindow" value="true"/>
            <Property name="ObjectName" value="employee"/>
            <Property name="System" value="SAP_ERP_HumanResources"/>
          </Properties>
          <Descriptions default="defaultAction"/>
        </Action>
      </Actions>

    </ItemType>

Even after these steps the value of parameter LRF_REQUEST is empty when we see the technical help after opening the task from the UWL.

Am i mssing any thing or any other configuration is requred? please help.

Thanks & Regards

Jeet
