[OpenLayers-Users] Problem with GML features

[Dmitri Mizerkin]

Hello everybody!

I'm experiencing problems with handling the features of a GML layer, which
is loaded when the page is opened. The problem is that after the 'loanend'
event is raised, the features-property of the layer stays empty for some
more time, so there is no way to examine the features in this handler. In my
case I need to extract the bounds-properties of the features to construct an
common bounds-object for zooming (the action should simulate feature
selection and zooming to the selection).

Any ideas, how this could work?

Here's my code snapshot:

function SelectFeature() {
  var layer = GetLayerByName(FEATURE_LAYER); //returns a MapServer layer to
send a request on
  if (layer == null)
    return;
  var selection_url = CreateWFSGetFeatureRequest(layer, FIELD_NAME,
FIELD_VALUE); //creates a WFS GetFeature-request
  if ((selection != null)&&(selection.map != null)) {
    OLMap.removeLayer(selection);
    selection = null;
  }
  selection = new OpenLayers.Layer.GML("Selected Objects", selection_url);
  OLMap.addLayer(selection);
  selection.displayInLayerChooser = false;
  selection.events.register("loadend", selection, ZoomToSelection);
  selection.events.triggerEvent("loadend");
}

function ZoomToSelection() {
  var bounds = ComputeSelectionBounds();
  if (bounds == null)
    return;
  OLMap.zoomToExtent(bounds);
}

Thanks in advance!
