Hello Group,

with my basic knowledge of core commands api I recently stood before a
wall. Not knowing how to do this..

Folowing problem ..
I have in my Model an Object linking to several owners (User objects)

is it possible to create in a Popup menu (more precisely in a submenu in
a popupmenu)

one entry for each user of the file.

So I imagine a submenu called "Send message"
and in it one entry for each user named after the user i.e. user.getName();

Would that scenario be possible with commands and handlers (how?) or do
I have to use actions for this?

You would do something similar to the Window>Show View menu. Use a menuContribution to contribute a dynamic element, a subclass of org.eclipse.ui.actions.CompoundContributionItem. You can implement org.eclipse.ui.menus.IWorkbenchContribution if you need to get any services.

Your command to send mail would take an optional parameter, i.e. com.example.sendMail would have a parameter named com.example.sendMail.email. A static menu contribution might look like:

<command id="send.paul" commandId="com.example.sendMail"
label="Send: Paul">
<parameter name="com.example.sendMail.email" value="pwebster@example.com"/>
</command>

When asked for the contribution items, you would be generating CommandContributionItems from an CommandContributionItemParameter similar to org.eclipse.ui.internal.ShowViewMenu.getItem(String)
