I am a newbie for TM1 and for this forum too

To start with, we are facing a problem in drill through functionality in Cognos TM1 (Version 10.2 Hot Fix). The drill through has been designed from a Summary cube with consolidated numbers onto a more detailed cube where individual trade details are provided.
Problem: Was able to successfully create the drill through process and tested it out from Perspectives/Architect and it works fine. However, we have the same cubeview(The Originating cube's view) published to our Web portal. So, when I right click there I get a 'Drill' option. When I click on that I can see from Tm1Top that the drill TI process is kicked off too and completes successfully. But, I am not taken to the destination detailed cube's view. I do see the view created and everything done as expected at the back end but the destination cube view simply wont show up after everything is done.
Is this some kind of known bug or am I missing something?
Thanks,
Karthik
