When you are deep down the component tree how do you display a dialog? m.top is not my “scene” component and there for nothing happens when I set m.top.dialog.
I believe the way to do this is to have a field on the child node that’s observed by the parent node. The parent can then see that field changed and set its own field observed by its own parent to pass it on up to the top, where it would be observed and displayed.
