User Decision Box while Rejecting in UWL

Hi,

How we can show popup or any text box while rejecting the TASK. We have done changes in UWL XML file.

<ItemType defaultView="TS99000059_view" connector="WebFlowConnector" name="uwl.task.approval.webflow.TS99000059.SAP_ECC_HumanResources">

<ItemTypeCriteria connector="WebFlowConnector" externalType="TS99000059"/>

-<Actions>

-<Action name="accept" handler="UserDecisionHandler" groupAction="yes">

-<Properties>

<Property name="decisionKey" value="2"/>

<Property name="UserDecisionTitle" value="Approve the request"/>

<Property name="UserDecisionNote" value="true"/>

</Properties>

<Descriptions default="Approve"/>

</Action>

-<Action name="reject" handler="UserDecisionHandler" groupAction="yes">

-<Properties>

<Property name="decisionKey" value="1"/>

</Properties>

<Descriptions default="Reject"/>

</Action>

</Actions>

</ItemType>.

We have successfully uploaded the file in the system and clear the cache.  But the there is no textbox after click on approve button.

We have done the entry in SWFVISU tcode for the task that we have mentioned in the UWL file.

Please let us know how to configure.
