I have read here https://bdsc.webapps.blackberry.com/devzone/blackberry10devalpha/ that "The Developer Relations team will be actively involved in providing developer support in the forums", so I post another question.

When assigning a contextmenu to a control inside a ListItemComponent, it doesn't seem possible to reference the id of the surroudning page or container from inside the ActionItem's onTriggered

I get this runtime error: ReferenceError: Can't find variable: navigationPane

ActionItem {
	imageSource: "asset:///images/myimage.png"
	onTriggered: {
		navigationPane.deprecatedPushQmlByString ("NextScreen.qml");
	}
}

So how can I implement this use case in QML:

1) Have a list displayed in the UI

2) Long press on an item

3) The pressed item will become selected and the context menu pops up

4) The user selects an action from the context menu that pushes the next View onto the stack

take a look at the definition of your NavigationPane, does it have the correct id? In your case it should be navigationPane.

NavigationPane {
    id: navigationPane

Yes I have the id of my NavigationPane set to navigationPane. The statement works when assigned to a Button's onClicked, but not when assigned to a ListItemComponent's onTriggered.

i would suspect a bug there, seems that the visibility of the id is not correct, but if it is correctly defined in the qml that is a system-side error.

Since it's deprecated so I suggest you not to use it. In stead, you can have other options such as attachedObjects which holds sme Pages and just push them when need.

attachedObjects: [
        Page {
            id: firstPage
            content: Container {
                Label {
                    text: "First attachedObjects Page"
                }
            }
            paneProperties: NavigationPaneProperties {
                backButton: ActionItem {
                    onTriggered: {
                        navigationPane.pop ();
                    }
                }
            }
        },
        Page {
            id: secondPage
            content: Container {
                Label {
                    text: "Second attachedObjects Page"
                }
            }
            paneProperties: NavigationPaneProperties {
                backButton: ActionItem {
                    onTriggered: {
                        navigationPane.pop ();
                    }
                }
            }
        }
    ]

 Or control the push and pop from C++
