I would contribute some commands to the pop-up menu of the project
explorer view; for this purpose I defined the following menu contribution:
<extension
point="org.eclipse.ui.menus">
<menuContribution
locationURI=" popup:org.eclipse.ui.navigator.ProjectExplorer#PopupMenu?aft er=additions ">
<command
commandId="myplugin.command.mycommand"
icon="icons/etool16/mycommand.png"
label="Run mycommand"
mnemonic="M1+P"
tooltip="Do something with this project">
</command>
</menuContribution>
</extension>
this works fine, i.e. the command appears in the popup menu.
However, when I try to add a filter to have the command visible only
when a project with a given nature is selected:
<visibleWhen>
<test property="org.eclipse.core.resources.projectNature"
value="myplugin.natures.mynature">
</test>
</visibleWhen>
the command simply disappears!
This happens also for any other kind of visibleWhen filter; maybe I'm
missing something, but what?
Thanks a lot for your time reading this post
Regards,
Patrizio

Thanks a lot Paul, adding the iterate element solved the problem, Now
I'm able to get my command when a project with the given nature i
selected in the project explorer.
However I get it also when I right click on an empty space in the
project explorer; in this case the selection is empty (null) so the
handler doesn't execute, but it would be nice to hide the command when
the selection is empty.
Is it possible to achieve this with the visibleWhen condition ?
Thanks again for your help
Regards,
Patrizio
