How to access features of openlayers2 map instance/object and to add featureselect event?

Hi

I have a add content page that has a single field with map widget.

As per documentation I should have access to map but it results undefined:

var ol = jQuery('#openlayers-map').data('openlayers'); // Undefined

I think that figured out how it can be accessed:

var ol = Drupal.settings.openlayers.maps['openlayers-map'];

How to add featureselect event on current maps features?
To get something to loop over and assign select functionality.
