[Users] Using LegendPanel with Tilecache...

[Paul james]

Thanks Ryan...

But I found other solution...
I edited the setUrl method from LegendImage.Js...

Before
 setUrl: function(url) {
        this.url = url;
        var el = this.getEl();
        if (el) {
            el.un("error", this.onImageLoadError, this);
            el.on("error", this.onImageLoadError, this, {single: true});
            el.dom.src = url;
        }
    },


My modification
 setUrl: function(url) {
        this.url = url.replace("tilecache.py?","
http://localhost/cgi-bin/mapserv.exe?map=Map.map&");

        var el = this.getEl();
        if (el) {
            el.un("error", this.onImageLoadError, this);
            el.on("error", this.onImageLoadError, this, {single: true});
            el.dom.src = this.url;
        }
    },


Worked fine!

Thanks
