When it is called at the end of the drag moving the image, e.touches has zero length, so trying to use e.touches[0] causes an exception. I changed it to use e.changedTouches instead. Not sure whether it makes any sense, but at least it makes the problem go away. The caller of getMousePosition() is mouseEventToContainerPoint() in loleaflet/src/map/Map.js, and the caller of that is _onDragEnd() in L.Handler.PathDrag in loleaflet/plugins/path-transform/src/Path.Drag.js. All the lines of code that _onDragEnd() would have executed after calling mouseEventToContainerPoint() get skipped because of the exception. Presumably it is those lines of code that are supposed to reinstate the normal scrolling behaviour. Likely it does not make sense to call mouseEventToContainerPoint() in that _onDragEnd() as a touchend event by definition is fired when the touch has finished, and there no longer is any current "mouse" position. w3schools.com says "The touches property returns an array of Touch objects, one for each finger that is currently touching the surface", and as the touch has ended, no finger is touching the surface any longer. Or is this browser dependent?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
