created issue #1

Apr 4, 2012 10:01AM

Observed in every browser I tested, with the last API version.

Steps to reproduce:
- Create a Map '_map' and add a draggable Marker on it
- Drag the marker and drop it to a new position
- setMap(null) on the marker -> it disappears, as it should
- setMap(_map) on the marker -> it should reappear, but it doesn't

I reproduced this bug only on dragged markers.
When using the 'visible' property instead of 'map', it works correctly.

I had thought my report was precise enough for you to reproduce it faster than me...

Anyway, here is a link to a demo :

This bug seems related to what I have experienced:

Draggable markers disappear after being dragged if map property is set again

Steps to reproduce:
- create a map and add a draggable marker
- add an event listener to the click event which updates the position of the marker and also sets the map attribute again
- drag the marker
- click anywhere in the map
--> the marker disappears

Demo:

This can easily be resolved by not setting the map attribute again in the click listener.

Google: this bug also breaks the very popular MarkerCluster and MarkerClustererPlus utility libraries. See

I can confim that it is also now working for this:
marker.setMap(null)
marker.setMap(map)
marker.setAnimation(google.maps.Animation.BOUNCE)
markerSetanimation(null)
market.setMap(null)
marker.setMap(map)

Thanks for the fix!
