???dummy.action.VISI_Lums_View_Lums.display.name???

When trying to view a Lumina document from BI Launchpad, the menu context shows ???dummy.action.VISI_Lums_View_Lums.display.name??? instead of View as expected. When click on that entry, we get 404 missing Page error.

Our environemnt is:

BI Platform 4.1 SP06 Patch 3 with both NW 7.4 and WACS as Web Server on Windows

Lumina Server for BI Platform 1.28 P3

We saw some posts talking about similar errors but no solutions have been helpful in fixing that problem.

Any help will be much appreciated,

Thanks a lot,
