[OpenLayers-Users] Re: Zoom to selected features

[gabriel]

Hi, i working on function, which will zoom to selected feature/s from CQL.
Here is my syntax: 

function filtrovanie()
    {
      var cql = document.getElementById("select").value;
      var hodnota = document.getElementById("dopyt").value;
      var vypis = cql+" "+hodnota;
      var format = new OpenLayers.Format.CQL();
      var filter;
      filter = format.read(vypis);
      if(filter)
      {
          rule.filter = filter;
          wfs.redraw();
          map.zoomToExtent(new
OpenLayers.Bounds(wfs.selectedFeatures[0].getDataExtent()));          
      };

      return false;      
    }

I got this error message : 
Cannot call method 'getDataExtent' of undefined

I also tried to set wfs.selectedFeatures[0].geometry.getBounds().clone() ,
but nothing happened. 
Can you say me what is wrong?
