Looking at the Feed Viewer sample in Ext 4 release. The contextual menu doesn't work.

Seems that the listener 'contextmenu' is replaced with 'itemcontextmenu'.


Modifying the file 'FeedPanel.js' is required to get contextual menu working.

CHANGE:


Code:
            listeners: {
                scope: this,
                contextmenu: this.onContextMenu
            },
Code:
    onContextMenu: function(view, index, el, event){
        var menu = this.menu;

        event.stopEvent();
        menu.activeFeed = view.store.getAt(index);
        menu.showAt(event.getXY());
    },

TO:


Code:
           listeners: {
                scope: this,
                itemcontextmenu: this.onContextMenu
            },

Code:
    onContextMenu: function(view, rec, node, index, event){
        var menu = this.menu;

        event.stopEvent();
        menu.activeFeed = view.store.getAt(index);
        menu.showAt(event.getXY());
    },
