[news.eclipse.modeling.gmf] Get ride of "Input methods" menu in ContextM

[j.cardenete@xxxxxxxxxx (Javier )]

Working in a DiagramEditor and showing the ContextMenu for any EditPart, I 
have always seen the following menu in the ContextMenu: InputMethods. I 
would like to get ride of this but I dont know how.

I tried two ways but none of them worked out. First one, as I made with 
some other options:

<contributionItemProvider
		checkPluginLoaded="false"
   
	class="org.eclipse.gmf.runtime.diagram.ui.providers.DiagramContributionItemProvider">

        <Priority name="High"/>
        <popupContribution
       	id="remove_popup_menu_id"
   
		class="org.eclipse.gmf.runtime.diagram.ui.providers.DiagramContextMenuProvider">

	         <popupStructuredContributionCriteria
	    		objectClass="org.eclipse.gef.EditPart">
	         </popupStructuredContributionCriteria>
	         
	    	<popupPredefinedItem id="navigateGroup" remove="true"/>		
	    	<popupPredefinedItem id="addGroup" remove="true"/>
         </popupContribution>
   </contributionItemProvider>

But I dont know which ID should I use in case I can follow this  method.

Second way, I have my own DiagramContextMenuProvider class, in the 
buildContextMenu() method I look at every IContributionItem contributed 
but the Input Methods menu doesn't appear.

Any help would be appreciated!

Thanks in advance.
