How to get TaskId's Information using UWL in Webdynpro?

Question

Hi,
  I've to get TaskId's Information using UWL in WebDynpro
  from SAP R/3 workflow.
  For e.g.  Name, Creation Date, Status etc.
I'm able to see property Value in WebDynpro but instead of Property Value I want same Information in WebDynpro without using any Functional Module from R/3
I'm giving the XML file structure which I'm using
I want to display information about the task Id which I'm giving in this configuration.
<?xml version="1.0" encoding="utf-8"?>
<! DOCTYPE UWLConfiguration PUBLIC '-//SAP//UWL1.0//EN' 'uwl_configuration.dtd' [
  ]>
<UWLConfiguration version="1.0">
  <ItemTypes>
    <ItemType name="uwl.task.webflow.TS91000129.UWL" connector="WebFlowConnector"
defaultView="Test" executionMode="default" defaultAction="launchWebdynpro">
<ItemTypeCriteria systemId="UWL" externalType="TS91000129" connector="WebFlowConnector"/>
<Actions>
<Action name="launchWebDynPro" handler="SAPWebDynproLauncher"
  returnToDetailViewAllowed="yes" launchInNewWindow="yes" launchNewWindowFeatures="width=800,height=600,resizable=yes,scrollbars=yes,status=yes,toolbar=no,menubar=no,location=no,directories=no">
  <Properties>
    <Property name="WebDynproApplication" value="TEST"/>
    <Property name="WebDynproDeployableObject" value="local/TEST1"/>
    <Property name="isnewwindow" value="1"/>
    <Property name="fruit" value="apple"/>
    <Property name="DynamicParameter" value="wi_id=${item.externaId}"/>
    <Property name="System" value="LocalSystem"/>
  </Properties>
</Action>
</Actions>
</ItemType>
  </ItemTypes>
</UWLConfiguration>
Then in WebDynpro application I'm using this code
String text = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("DynamicParameter");
If I give any other property name I'm able to get in WebDynpro application.
But I tried it for Task Id using Dynamic Parameter I was getting a Blank Value.
Please Help Me.

Hi Niharika,
I think you have a typo in your code. You can retrieve the work item id by using [code]<Property name="DynamicParameter" value="wi_id=${item.<b>externalId</b>}" />[/code] instead of [code]<Property name="DynamicParameter" value="wi_id=${item.<b>externaId</b>}"/>[/code]
In addition, you can get values from the work item container by extracting them as custom attributes:
[code]<ItemType name="uwl.task.webflow.TS90000001.<system id>" connector="WebFlowConnector" ...>
  <ItemTypeCriteria ... />
  <CustomAttributes>
  <CustomAttributeSource id="WEBFLOW_CONTAINER" objectIdHolder="<element name>" ...>
  <Attribute name="<element name>" type="string" displayName="<element description>" />
  </CustomAttributeSource>
  </CustomAttributes>
  <Actions>
    <Action name="launchWebDynPro" handler="SAPWebDynproLauncher">
      <Properties>
        <Property name="DynamicParameter" value="<custom param>=${item.<element name>}" />
      </Properties>
      <Descriptions default="" />
    </Action>
  </Actions>
</ItemType>[/code]
Hope this helps,
