Buttons donu00B4t appear in the UWL for UserDecisionHandler

Hi,

I try to make decisions avaible straight from the UWL using the UserDecisionHandler in my config:

<name="uwl.task.webflow.decision.admin.Procurement.TS14508044.SAP_EBP" connector="WebFlowConnector" defaultView="Procurement_DecisionTasksView" >
 <ItemTypeCriteria systemId="SAP_EBP" externalType="TS14508044" connector="WebFlowConnector"/>
<Action name="approve" groupAction="yes" handler="UserDecisionHandler" returnToDetailViewAllowed="yes" launchInNewWindow="no" >
<Properties>
<Property name="decisionKey" value="2"/>
</Properties>
<Descriptions default="Approve">
</Descriptions>
</Action>
<Action name="reject" groupAction="yes" handler="UserDecisionHandler" returnToDetailViewAllowed="yes" launchInNewWindow="no" >
<Properties>
<Property name="decisionKey" value="1"/>
<Property name="UserDecisionNote" value="mandatory"/>
</Properties>
<Descriptions default="Reject">
</Descriptions>
</Action>
</Actions>

After I have cleared the cache and log off and on, not any buttons disabled as expected.

Thx for help
