[OpenLayers-Users] geojson - Performance issue

[David custodio]

Hi Andreas, I have a code exactly you suggest , using WMs

 post, sld_body and filter in rules. The 

user define the conditions and the legend, fillcolor, stroke-color, etc...

May problem is to show the legends using geoext.legendpanel. 
The layers defined by user appear
 
only the title in legendpanel, but the icons not show. 
Do you any solution for the problem ? 

Legendpanel is enable to show this type of layer ?
