[Cartoweb-users] how to refresh legendlayersaftermapoverlayoperation?

[Oliver Christen]

you can access a plugin object this way on server side:
$mapOverlay = $this->serverContext->getPluginManager()->mapOverlay;
or
$mapOverlay = 
$this->serverContext->getPluginManager()->getPlugin('mapOverlay');

though, calling getInit(); at that level may have unexpected results, as 
there are quite some operation behind that beside icon generation.
