Hello,
I'm trying to combine the nice turorials from Prakash about the command
framework (http://wiki.eclipse.org/Platform_Command_Framework) and those
about menu contributions (http://wiki.eclipse.org/Menu_Contributions).
What I try to accomplish is a dynamic submenu populated with a
parameterized command. (a couple of items with the same command)
So, I defined the command with a parameter in the manifest. Also I
defined the menu with a dynamic field which uses a CompoundContributionItem.
During the call from CompoundContributionItem#getContributionItems() I
create CommandContributionItem s using CommandContributionItemParameter.
It actually works fine when there are no parameters given - the menu is
populated with the Command and the label set in
CommandContributionItemParameter.
But once I set a parameter the whole submenu is set inactive (grayed out).
Maybe I don't see the obvious solution but up to now i couldn't find one.
Creating a breakpoint during those calls causes eclipse, java and parts
of the operating system to hang. (I assume because it stops during a
system call, right?)
Using ISelectionService instead of a CommandParameter won't work for me
because the information I need is not in a selection - if I understood
the concepts right.

Hi Paul,
thanks a lot! It seems to work (doing a quick evaluation).
Now that I see it, it totally makes sense - silly me!
Anyways, the tooltip for the CommandContributionItemParameter
constructor only talks about parameter "names and values".
Also, the tutorial about commands by Prakash and the ones about menu
contribution seem to use the "name" as the first argument in the map.
It's either misleading/wrong or a diffrent usecase. But actually i don't
see the difference.
Thanks, again.
