Hi,

I’m still getting console error with message “[Vue warn]: Error in v-on handler: "TypeError: _this2.watcher is not a function” (from QPopupEdit component)
while using QPopupEdit inside of QTree “default-header” scoped-slot.
If I copy the code with interpolated variable and with <q-popup-edit> bellow and place it somewhere else, then it works.

What I found so far is that QPopupEdit “show” event does not even fire. So the watcher method is not set and when “before-hide” event triggers, no watcher exists.

Also interesting thing is if I move that part as it is in “default-body” scoped slot with the same { node } context it magically works.

Thanks for any help or clue
