Hi,
Steps:
1/ Have a scheduler with both agenda and week agenda extensions.
2/ Open the week agenda.
3/ Open the regular agenda.
4/ Double click to create an event.
Result:
It break with the error “Uncaught TypeError: Cannot read property ‘length’ of undefined”.
On scheduler._mouse_coords at this._colsS.heights.length, line 2364.
On my implementation it breaks right away without the step 4, and loop, but I guess I’ve some other extension that triggers mouse events.
