This bug happened for me in two places: in tmm menu, opened by command
tmm-menu (no matter, is menubar enabled or not), and its popup variant,
which may be opened by C-Mouse3 if menubar is disabled.
When only one of these two modes is enabled (either semantic or EDE),
menu is available, but after activation of remaining one submenu turns
to inactive usual menu item. But disabling of one mode, makes submenu
available again in both places.
Versions.
emacs - 23.4 (built menually, since in repo i had only 23.3), 24.2.1
and snapshot for debian from cassou personal package archive on
launchpad.
cedet - both builtin (own for each emacs version) and snapshot from bzr.
Already discussed this on cedet-devel mailing list, discussion is
under link below, where screenshots are available:
http://sourceforge.net/mailarchive/forum.php?thread_name=5148F5AC.6070502%40siege-engine.com&forum_name=cedet-devel
-------------------------------------------------------------------
Note, only first two posts are valuable for moment of this report. To
be brief in that discussion — i referred to popup menu, i'm talking
about, as "Global Menu" . Strange, how it may be wrong, when looking to
screenshots makes it fully clear.

Since it took me quite some time to understand this, here's a recipe:
* emacs -Q
* M-x menu-bar-mode, so that menu-bar is disabled
* M-x semantic-mode
* M-x global-ede-mode
* Now do C-Mouse 3 to open the "global menu" popup (which I didn't know
existed until yesterday...)
Look at the "Development" menu at the bottom. It might be disabled. If
not, try the recipe again - it seems to be a race condition.
If the item is disabled, turn on the menu-bar, and you'll see that the
Development menu there is working just fine.
The culprit is this: Both minor-modes, semantic and ede, should use the
"Development" menu, but you can use one or the other or both
together. This hack in semantic.el is used to accomplish this:
(define-key map [menu-bar cedet-menu]
(list 'menu-item "Development" cedet-menu-map
:enable (quote (not (bound-and-true-p global-ede-mode)))))
If you remove the :enable clause, the menu-bar displays two "CEDET-menu"
items underneath "Development", which is what this hack avoids. (Note
however that the "Global menu" popup will display correctly in this
case, so there's the first inconsistency between the two).
With this hack, the menu-bar works fine. It seems however that the
"Global Menu" popup displays *either* the item from Semantic *or* the
one from EDE, but only the latter is enabled. This is also where I guess
the race is happening.
I hope this information is sufficient to track this down. Otherwise I'll
try to come up with an isolated test case.
BTW, I managed to workaround this issue in CEDET trunk by using
:enable (quote (not (and menu-bar-mode
(bound-and-true-p global-ede-mode))))))

I was wrong here; there's no race condition, but it depends on the order
of mode activation. If you *first* enable global-ede-mode and then
semantic-mode, the Development menu will be disabled. So to be clear:
the above recipe is false; you have to do 'M-x global-ede-mode' first,
and then do 'M-x semantic-mode'.

It actually seems that the menu entry that is displayed is the one which
was activated last.
As Nikita already wrote in his initial report, the text-mode menubar
(M-x tmm-menu) has the same problem, though I don't if it uses the same
code as the "Global Menu" popup.

I could not seem to reproduce this. Was it fixed?

I managed to work around it with this patch, which is also in Emacs:
http://cedet.bzr.sourceforge.net/bzr/cedet/code/trunk/revision/8507
I think there is a bug in how the global menu is handling this, but I
guess that should be a separate bug report? IOW, I'd have no problem
with closing this.
