i have following situation:

a polyline added on map , when user clicks on state changes editable. have event if user clicks last vertext of polyline , starts moving mouse able extend polyline mouse path user drawing.

however seems when have event , inside event try add 1 not work , don't kwow why.

just in case make things simpler undrstand paste part of code.

google.maps.event.addlistener(polyline, "mousedown", function(event){                if(polyline.geteditable() === true)                 {                    if(typeof event.vertex !== "undefined")                     {                             if(event.vertex === polyline.getpath().getlength() - 1)                          {                             polyline.seteditable(false);                                  if(mousemovedrawingevent === null)                                 {                                     map.setoptions({draggable:false});                                     polyline.setoptions({clickable:false});                                     mousemovedrawingevent = google.maps.event.addlistener(map, "mousemove", function(event)                                      {                                         alert("1"); // <== never fires                                         polyline.getpath().push(event.latlng);                                         drawinglabel.setpoint(event.latlng);                                         drawinglabel.setcontents("<div style='background-color:white'>" + (google.maps.geometry.spherical.computelength(polyline.getpath()) / 1000).tofixed(2) + " ΠΊΠΌ.</div>");                                     });                                 }                                  map.getdiv().onmouseup = function(ev) {                                 polyline.setoptions({clickable:true});                                 map.getdiv().onmousedown = null;                                 map.getdiv().onmouseup = null;                                 google.maps.event.removelistener(mousemovedrawingevent);                                 mousemovedrawingevent = null;                             };                         }                    }                }            });
