Mapstraction: Changing an Icon's image URL after it has been added?
- by Paul Owens
I am trying to use marker.setIcon() to change a markers image. However it appears that although this changes the marker.iconUrl attribute the icon itself is using marker.proprietary_marker.$.icon.image to display the markers image - so the markers icon remains unchanged. Is there a way to dynamically change the marker.proprietary_marker.$.icon.image?
Add a marker.
Check the icon's image url and the proprietary icon's image - they're the same.
Change the icon.
Again check the Urls. Now the Icon Url has changed but the marker still shows the old image which is in the proprietary marker object.
