[OpenLayers-Users] mergeNewParams + Legend

[Sascha Müller]

Hi,

I tried this SLD with only two instead of five rules. It works.
Could it be, that the request 'GetLegendGraphic' is too long with the 
SLD inside?
Like mergeNewParams() without 'Post'  in 'OpenLayers.Layer.WMS'.

Is there a way to implement it?
Or is this more a GeoServer thing?
