Yet another issue with FP2, just right from the Stackoverflow / IBM frontline: Brian Gleeson from the IBM Ireland labs just confirmed the reported issue regarding the popup menus in OneUI application layout when using the 3.0.2 theme. I asked for it here: http://stackoverflow.com/questions/26387258/oneui-app-layout-error-with-pulldown-menus
I tested several combinations of Domino 9.0.1 with and without Fixpack 2 installed. One thing that is really annoying is that you fail even if you downgrade your server back to FP1 after you installed FP2 as the uninstaller leaves some files and settings.
I didn't figure out yet what to do to remove all the stuff that FP2 installed before - except from installing everything new from the scratch. If you have any ideas how to do it please let me know in the comments or (preferably) in the Stackoverflow post.
The issue is filed under BGLN9PXCS3.
Meanwhile Brian posted the answer on how to revert the Dojo stuff after the downgrade also on Stackoverflow. The main process is to remove the folder
and copy the folder
from a FP1 installation to the destination machine and restart the HTTP task completely.
Unfortunately I found another issue after manually downgrading. See my comment here: http://stackoverflow.com/questions/26387258/oneui-app-layout-error-with-pulldown-menus#comment41477129_26387258
