[OpenLayers-Users] map centers correctly when not in lightbox.

[Eric Mckenna]

Hello All,
I'm displaying the same map details in two different ways.  One is on a 
simple webpage, this one works flawless.

The issues occurs when I put my map into a jquery tools overlay, 
http://flowplayer.org/tools/overlay.html. 
When displayed with the overlay lib, my map has the correct center but 
the map is "scrolled" in that the center marker is in the upper left 
hand corner.

I've checked the projection and doubled checked the zoom value and 
center points.  They all look good to me.

One odd issue is that when I hit the zoom in or out scale button, the 
map corrects itself.

Any suggestions?


here's my code:
/**
 * Render the Hot Spot detail map with the provided configuration
 *
 * @param id
 *    The id of the div to use for the map
 * @param config
 *    The array of configuration options for the Hot Spot
 */
function hotspotsRenderDetailMap(id, config) {
  var lat = Number(config.latitude);
  var lon = Number(config.longitude);
  var zoom = Number(config.zoom);
  var image = config.marker;
  var hotspot = new OpenLayers.LonLat(lon, lat);

  OpenLayers.ImgPath = config.imgpath;

  var map = new OpenLayers.Map(id, {
      controls: [
          new OpenLayers.Control.Navigation(),
          new OpenLayers.Control.PanZoomBar(),
          new OpenLayers.Control.ScaleLine(),
          new OpenLayers.Control.LayerSwitcher()
      ],
  });
 
  // In case something needs to get at this later
  if (!Drupal.hotspotsMap) {
    Drupal.hotspotsMap = [];
  }
  Drupal.hotspotsMap[id] = map;
 


  var cloudmade = new OpenLayers.Layer.CloudMade("CloudMade", {
      key: 'c6ee2dab1ccd513e8ab325db51aa28b7',
      styleId: 3818,
  });
  map.addLayer(cloudmade);

  if (!map.getCenter()) {
    var epsg4326 = new OpenLayers.Projection("EPSG:4326");
    hotspot.transform(epsg4326, map.getProjectionObject());
    map.setCenter(hotspot, zoom);
  }

  var markers = new OpenLayers.Layer.Markers("Markers");
  map.addLayer(markers);

  var size = new OpenLayers.Size(30,43);
  var icon = new OpenLayers.Icon(image, size);
  var marker = new OpenLayers.Marker(hotspot, icon);
  markers.addMarker(marker);
 
  for ( var i in config.overlays ) {
    var kml_features;
    kml = new OpenLayers.Layer.GML(config.overlays[i].filename, 
config.overlays[i].filepath, {
      format: OpenLayers.Format.KML,
      formatOptions: {
        extractStyles: true,
        extractAttributes: true,
        maxDepth: 4,

      }
    });
   
    selectControl = new OpenLayers.Control.SelectFeature(kml,
      {onSelect: onFeatureSelect, onUnselect: onFeatureUnselect});
    map.addLayer(kml);
    map.addControl(selectControl);
    selectControl.activate();

  }

  function onPopupClose(evt) {
    selectControl.unselect(selectedFeature);
  }

  function onFeatureSelect(feature) {

    selectedFeature = feature;
    //console.dir(feature.attributes);
    var bubbletxt = "<div><em>"+feature.attributes.name+"<em>";
   
    if ( typeof feature.attributes.description != "undefined" ) {
      bubbletxt += "<p>"+ feature.attributes.description +"</p>";
    }
    bubbletxt += "</div>";
    popup = new OpenLayers.Popup.FramedCloud("ab-feature",
                               
feature.geometry.getBounds().getCenterLonLat(),
                               new OpenLayers.Size(200,50),
                               bubbletxt,
                               null, true, onPopupClose);
    feature.popup = popup;
    map.addPopup(popup);
  }
 
  function onFeatureUnselect(feature) {
      map.removePopup(feature.popup);
      feature.popup.destroy();
      feature.popup = null;
  }

  // Move the marker layer to the top (for Firefox bug)
  map.setLayerIndex(markers, 100);
}
