[OpenLayers-Users] gml as base layer

[Francesco Geri]

Hello everybody,
I would try to use a GML layer like base layer but I always obtain errors. I used this code to load a gml file:


    mapx=new OpenLayers.Map('lmap',
    {projection: new OpenLayers.Projection('EPSG:900913'),
    displayProjection:new OpenLayers.Projection('EPSG:4326'),
    controls: []
    }
    );
    
    
    var layer = new OpenLayers.Layer.Vector("GML", {
        strategies: [new OpenLayers.Strategy.Fixed()],
        projection: new OpenLayers.Projection('EPSG:900913')
isBaseLayer:true,
        protocol: new OpenLayers.Protocol.HTTP({
            url: "dati/catasto_ok.gml",
            format: new OpenLayers.Format.GML()
        })
    }); 

If I put the layer without the base layer option the layer is loaded perfectly (with a OSM base layer), but when I try to put the GML file like base layer this disappear.

Someone can help me?

Thanks a lot!

Francesco
