Hello list,
I still have a problem with my TileCache configuration. I try something out but it doesn't work. I think it is a problem with the mergeNewParams Parameter in OpenLayers. All other layers work but the layer with the mergeNewParams doesn't. As new Param I get a php-Skript which generates an SLD-File for styling the map. I hope you can help me again. Without TileCache all works fine. And all layers without the mergeNewParams works, too. With the mergeNewParams Parameter I only get white Tiles without any error message. At the Server there are white png-files in the output Directory from Tilecache. Here are my code fragments. Perhaps you can see the error. I think my resolutions and my extents are ok.
