Hi,

You can try add the zoom callback function by override the ZK openlayer widget

<script><![CDATA[
zk.afterLoad('openlayers', function() {
    var _openlayers = {};
    zk.override(openlayers.Openlayers.prototype, _openlayers, {
        bind_: function (desktop, skipper, after) {
            _openlayers.bind_.apply(this, arguments);
            this.map.events.on({
                zoomend: this.proxy(this.zoomend)
            });
        },
        zoomend: function() {
            zk.log('current zoom level', this.map.zoom);
        }
    });
});
]]></script>
