[Cartoweb-users] how to refresh legend layers after mapoverlayoperation?

[Oliver Christen]

Hi

I presume the map cache is not refreshed.
Maybe you could try to force a map cache refresh. See this post on how to 
test that:
http://lists.maptools.org/pipermail/cartoweb-users/2008-February/003297.html
though in your case you would need to set some public variable or function 
in your mapoverlay plugin and access that from the getMap function from 
MapResultCache.php

A proper mecanism to force map cache refresh is not implemented yet, we are 
still thinking about how to do it in a clean way.

regards
Oliver
