You have to destroy the OpenLayers.Protocol.HTTP object and the
reinstatiate it what it is done with the following code snippet:

var proto = new OpenLayers.Protocol.HTTP({
  autoLoad: {
  url: myurl
  format: new OpenLayers.Format.GeoJSON()
});


now call GeoExt.form.Formpanel with the new proto object:
new GeoExt.form.FormPanel({
 ...
  protocol: proto,
 ...
});

Hope this helps.

Best regards

Juergen
