Blank header appears when validating leave request from the UWL

Question

Hello,
We are using SAP Portal 7.3 and BP_ERP5MSS 1.51 SP06 according note oss 1618269 with a backend ECC6 EHP5 SPS06.
We are facing the following issue :: "Leave Request Approval screen is poping with blank header".
This  issue occurs when launching the task TS21500003 from the UWL of the manager trying to validate a leave request.
See these screenshots,

[http://s9.postimage.org/7si0vfa7j/UWL_issue_2.jpg]
From NWA and Log traces we can find, but it is not sure it is relevant (due to some other iview not set yet) :
error : "Item with external id :<000000005010> and system id: <SAP_UWL >: Problem in performing action <markAsLaunched>: Unknown action: <markAsLaunched>-"
warning : "com.sap.security.api.NoSuchUserException: The given id " "is not a unique id of a user!"
We tried to follow some recommandations :
- Tx SWFVISU / Task TS21500003
- DYNPARAM = LRF_REQUEST_ID=${item.REQUESTID}
- and from portal : "Universal Worklist - Administration" / "my system alias" / Re-Register
- and clear cache
=> without success.
we tried :
- role : SAP_MANAGER_MSS_NWBC and SAP_ALL
- we assigned this role or this profile at our user test
=> without success.
we find :
- Note 1600953 : Modifications to UWL configuration file in BP MSS Add-On 1.0
=> but we didn't setup this Add-On, so we think this note is not relevant for us.
to investigate :
We have also tried to copy and past the XML indicated in note 1600953 for task TS21500003 and it did not solve the issue. We then came back to our initial XML.
We have configured the SAP_WebDynpro_XSS as indicated but we still face he same issue :
- when trying to open the task in the UWL, a pop up with a blank header opens. 
- when using the iview com.sap.pct.erp.mss.leave_request_approval, the system opens directly a leave request without showing the list of requests assigned to the manager.
Find step by step in this word document and the UWL information trace :
