jquery datepicker - activate another datepicker on select
===

I have 2 jquery datepickers to select a date range. 

Once I have selected a from date (from the first datepicker), I would like to activate the second (to) datepicker.

The code below does that, but for some reason closes the datepicker straight away.

Any ideas? - http://jsfiddle.net/rN4zu/

    From <input type="text" id="dateFrom" />
    To <input type="text" id="dateTo" /> 

jQuery
    
    $( "#dateFrom" ).datepicker({
        minDate: 0,
        maxDate: "+2Y",
        showWeek: true,
        weekHeader: 'Wk',
        onSelect: function( selectedDate ) {
            $( "#dateTo" ).datepicker("option", "minDate", selectedDate ).focus();
        }
    });
    
    $( "#dateTo" ).datepicker({
        maxDate: "+2Y",
        showWeek: true,
        weekHeader: 'Wk'
    });
