Hi,
I noticed today (in my product) that a lot of commands were disabled at the wrong time. I eventually found a whole pile of conflict messages in the log. What could cause this? Here are the messages:

Hi,

you have two plugins that declares in each plugin.xml the same command with the same id as it seems to be the same associated action, I think that you won't see the difference at runtime but it will be better if yoiu know why they they are declared twice.

Hope this will help,

Regards,

It looks like some path through the ProjectExplorer is causing handlers to be registered twice through their subactionbars. Please open a bug report at:

Thanks, Paul.

I guess I'd better check my Common Navigator contributions to make sure this isn't my fault... If I can't find any explanation I'll file a bug.

Mark.

Hello Mark,
I know it has been a long time since you asked this, but did you even find the cause of the problem?

Man, you're going back years... Shocked

Unfortunately, I don't recall if I ever figured out it was my problem, or a bug in the Platform. Since it looks like I never filed a bug, it must have been my fault. Smile
