RefreshUWLBackend : not working in a dummy - hidden iView on UWL page

Question

Experts,
We are stuck with the recurring outstanding issue of "Uwl passive refresh post approval or rejection of task item" , the requirement is to auto refresh the UWL iView post approval of a task item.
1. User selects a task item from UWL, a BSP application opens up ,
2. Post approval in the child window, we use javascript to close the child window and
3. Refresh the parent window to the UWL page..
4. On the Custom UWL page, we have put in a custom jspdynpage iView which calls
     EPCM.raiseEvent("urn:com.sap.netweaver.bc.uwl.ui", "refreshUwlBackend");    i.e. in the onLoad javascript function
     of the JSP, this is to achieve the refresh of UWL from the backend on every UWL page refresh
But it seems that call to "refreshUwlBackend" is not getting executed or is not functional ??
Request inputs on what all could be missing or incorrect ..........
Regards,
Paras

Hi Thomas,
KM has an authentication stack.  Perhaps you need to change the configuration of the KM stack?  In one case, we had to set our KM stack to accept cert instead of prompting for basic authentication.
Here is some help on it:
