I have a Ext.tree.Panel and I like to show a "context" Menu onTreePanelItemContextMenu as well as onTreepanelContainerContextMenu. After choose a Menu entry I have to get the selectionModel to check if a node/leaf is selected.

For now the ContextMenu has a own View so it has a own Controller etc.


now if the menu item is clicked ...

how can I get the selection Model of the MainView.TreePanel ... Is there a way? Or did I have to define the events in my Main Controller? which way is the "right" way or let's say "best practice"

seems that

var treePanel = Ext.widget('mainview').getReferences().treePanel;

do the trick

Ext.widget() creates a new component instance, so you don't want to do that. I think that you should handle all of this within the tree panel controller.

Oh ok, thats why my selection is empty !?:((

But how can I handle the ContentMenu Events (item click) in the tree panel controller?? for example I choose "rename" from the context menu -> load the selected record to a form.

I could create a global reference to my mainView and access that via Project.app.getController('Main') ... but maybe there is a better way to share data and call function from one view controller to another?
