[Cartoweb-users] how to refresh legend layers aftermapoverlayoperation?

[Oliver Christen]

Another possibility is the icones are generated before the mapOverlay 
transformation.
>From what I see, the call is initiated in getInit in LayersInitProvider.php 
(getInit>fillDynamicLayers>fillDynamicLayer>getClassIcon).
This is a bit annoying as it is the most early stage on server side.

So you can try to do the mapoverlay transformation at that stage too and 
pray it will work, ortherwise you would need to find a way to regenerate the 
related layer's icon image after applying the mapoverlay transformation.
