[Analysis]
In MapMenu.js

var dest = new OpenLayers.Projection(data.maps[0].projCode);
ce = ce.transform(this.oMap.oMapOL.baseLayer.projection, dest);

but the layer's projCode implementation in openlayers.js used in Fusion makes the projCode always be EPSG:4326. so the transformation might be invalid, and the calculated extent might not make any sense.

[Workaround]

        if(data.maps[0].layerOptions.projection)
        {
            var dest = new OpenLayers.Projection(data.maps[0].layerOptions.projection);
            ce = ce.transform(this.oMap.oMapOL.baseLayer.projection,dest);
        }
}}}[[BR]]

we will transform the coordinate system only if the layer contians the projection info. Fo the other layers, just keep the original behavior.

in general this patch is ok but isn't it better to check 'data.maps[0].projCode' for a projection code rather than data.maps[0].layerOptions.projection? How are you defining the map object in the AppDef?

[liuar]

All my layer's projCode is Epsg:4326, no matter which coordinate system assigned to the map. That's why I have to get the layerOptions.projection value.

This is a sample of map group with one map in AppDef,

<MapGroupType id="Sheboygan">
    <Map>
      <Type>MapGuide</Type>
      <SingleTile>true</SingleTile>
      <Extension>
        <ResourceId>Library://DID 1272737 Theme with commercial layer/Sheboygan.MapDefinition</ResourceId>
        <SelectionAsOverlay>true</SelectionAsOverlay>
        <SelectionColor>0x0000FFA0</SelectionColor>
      </Extension>
    </Map>
    <Extension />
  </MapGroupType>
