[OpenLayers-Users] SelectFeature working at the same time in two different overlays?

[Bart van den Eijnden (OSGIS)]

Use 1 SelectFeature Control and initialize it with an array of layers.

    /**
     * Constructor: OpenLayers.Control.SelectFeature
     * Create a new control for selecting features.
     *
     * Parameters:
     * layers - {<OpenLayers.Layer.Vector>}, or an array of vector layers.
The
     *     layer(s) this control will select features from.
     * options - {Object}
     */

Best regards,
Bart
