[news.eclipse.platform] registerContextMenu question

[Anand Narasimhan <anandn@xxxxxxxxx>]

Hi,

The IWorkbenchPartSite interface defines two registerContextMenu methods.

public void registerContextMenu(MenuManager 
menuManager,ISelectionProvider selectionProvider);

public void registerContextMenu(String menuId, MenuManager menuManager,
            ISelectionProvider selectionProvider);


It is not clear to me what the purpose of the second API is. I have a 
few questions.

1. Where is the "menuId" argument used?
2. Why would someone want to register multiple context menus with the site?
3. If I have multiple viewers (table viewers) in the view part, should I 
register a context menu for each viewer?
4. If I have a viewer contribution for this part containing this site, 
does the contributution show up in all the context menus registered for 
this part?

Another different question, but related to context menus. I have an 
editor part implemented, but not file based editor. It has a jface table 
viewer in it. If I register the editor context menu on this table, will 
the object contributions defined for object types shown in this table 
show up in the popup menu?

Thanks
Anand
