Exclusive menu item check-mark not working

[Tom asso]

I am running Qt 6.8 on ubuntu 22.04.3.
My QML dynamically adds checkable MenuItems to a menu, using Repeater and a model. I want those items to be exclusively checkable, but they are not; i.e. when I select an item, it becomes checked - as are all previously selected item:

	Menu {
	    title: 'Mouse mode'
	    id: mouseModesMenu
            Repeater {
	      model: mouseModes
	      visible: true
	      MenuItem {
	        text: modelData; checkable: true;
                ActionGroup.group: mouseModeActions
                onTriggered: { console.log('selected ', modelData);
		               topoDataItem.setMouseMode(modelData)}		
	      }
	    }
	  }

    ActionGroup {
        id: mouseModeActions
        exclusive: true
    }

What am I doing wrong?
Thanks!

Use Actions inside the Repeater, associate them with the ActionGroup, and bind them to the MenuItem.

Menu {
    title: "Mouse mode"
    id: mouseModesMenu

    Repeater {
        model: mouseModes

        Action {
            id: mouseAction
            text: modelData
            checkable: true
            ActionGroup.group: mouseModeActions

            onTriggered: {
                console.log("selected", modelData)
                topoDataItem.setMouseMode(modelData)
            }
        }

        delegate: MenuItem {
            action: mouseAction
        }
    }
}

ActionGroup {
    id: mouseModeActions
    exclusive: true
}
