can dynamic menus exist in global menubar? [message #331265]

My apologies if I don't get the terminology correct (first time poster)
but I have a plugin that is lazy-loaded and I want to place a dynamic menu
in the global menubar. The contributionclass that supplies the dynamic
tag is in my plugin.

<menuContribution locationURI="menu:file?after=file.New">
<menu
id="package.Label1"
label="ParentMenu">
<dynamic
class="plugin.package.ContributionItem1"
id="plugin.package.ContributionItem1">
<visibleWhen>
<reference
definitionId="plugin.inMainView">
</reference>
</visibleWhen>
</dynamic>
</menu>
</menuContribution>

I get a runtime error that the class can't be found.

org.eclipse.core.runtime - org.eclipse.ui - 0 - Class load Failure:
'plugin.package.ContributionItem1'

org.eclipse.core.runtime.CoreException: Plug-in plugin was unable to load
class plugin.package.ContributionItem1.

If I make the dynamic a pop up or view specific, it works however I have a
hard requirement that our functionality exists in the global menubar.

Any suggestions?

Aside from file.New being file.new I don't think it should make a
difference. Is the menu contribution in the same plugin that has the
class plugin.package.ContributionItem1?

Sorry for the long delay in response, holidaze weekend...

the file.New/new was a code scrub fat finger(my fault, not an issue) and
the menu contribution and the class are in the same plugin...

Any suggestions?

Paul and Matt,

I've been working with Matt on this issue and i've found 2 things.

1. A plugin that contributes a dynamic menu is started at bootup i.e.
doesn't seem to lazy load.
2. Having a plugin that contributes a dynamic menu in your RCP can
reorganize the activation order of the all plugins compared to an RCP
that has none.

In short, matt's original prob had nothing to do w/ eclipse dynamic
menus and everything to do w/ some of our core plugins asking for a
workbenchwindow before it should.

But... should the observation #1 from above be true? Should i put all
dynamic CompoundContributionItems in a sep plugin?

Hi Kevin,

Yes, the dynamic contribution item will be instantiated on the workbench
window creation, and that will force the plugin to start. Obviously it
should be instantiated when it needs to fill a menu or toolbar (in 3.4 I
believe it supports the more general ContributionItem). Since the main
menus aren't updated until they are actually shown, I think that we
could proxy the IContributionItem to delay loading as much as possible.
