ESS/MSS Leave Request Issue

Question

Hello All Experts
We have implemented ESS/MSS. Everything is working fine except the Leave Request approval. The approval request comes to the approver's inbox.When we try to open the approval request, the webdynpro application is getting but there is no data in the same. I mean the webdynpro application which is launched is blank.
Could anyone please try to help me how to make this webdynpro application up and running ?
We are using EP 7.0 with ECC 5.0
TIA,
Vivek

Hi Chuckie/Ton Groot,
As mentioned in post by Ton Groot,
I navigated to System Administration --> System Configuration --> Detailed Navigation --> Universal Worklist Workflow’ à ‘Universal Worklist - Administration’
I get a list of
Universal Worklist Systems
System Alias       Connector Type                       Action            Activate 
AdHocSystem |   AdHocWorkflowConnector  |                        | Deactivate 
SAP_ITS_XSS |   WebFlowConnector           |   Re-Register    | Deactivate 
ActionInbox     |   ActionInboxConnector        |                        | Deactivate
When I click on Re-Register button under Action, I get the following message
Item type registration was successful for the following systems:
- SAP_ITS_XSS (WebFlowConnector)
I have also cleared the cache by navigating to Cache Administration Page
Still the issue remains.
TIA,
Vivek
