[Users] LegendPanel fires GetLegendGraphic requests for invisible Layers

[Just van den Broecke]

Hi,

Another Legend issue, on GeoExt 1.1/OpenLayers 2.11:

When I add a LegendPanel to a Container, GetLegendGraphic requests are 
issued for every WMS Layer, even if these Layers are initially 
invisible. Basically the same issue as described here:
http://lists.osgeo.org/pipermail/geoprisma-dev/2010-October/000487.html
For maps with many layers this gives quite some init delay.

I would like to show/hide legends dynamically, only for Layers that 
become visible/invisible, possibly as a configurable option 
("showVisibleLayersOnly") on LegendPanel. I could not find an open issue 
or maybe there is a workaround. Thanks for any suggestions. Best,
