How do I bind a JQuery UI Datepicker to a text field in a CKEditor dialog?

Question

I'm trying to bind a JQuery ui Datepicker to a text field in a CKEditor dialog box. The error I'm getting says jQuery(...)datepicker(); is not an object. Which to me says that JQuery ui is not being loaded... ?

The intention is simply to get a datepicker bound to txtDlgReportDate. I can see that JQuery is being loaded when required but alert(jQuery.ui) returns 'undefined'.

My code is... (Creates a button for a CKEditor toolbar)

Thanks

And... the issue is that CKEditor doesn't just add an input tag but it surrounds it with a div and a table so the datepicker is added 'inline' to a div... To get it working in a 'click to show' type way we need to get the id of the input tag that's buried in the CK HTML and apply the .datepicker() function to it.

A working version (although it needs a bit more finessing) is....

    {
        type: 'text',
        id: 'txtDlgReportDate',
        label: 'Report Date:',
        onShow: function (data) {

            // Set the width of the outer div (otherwise it's affected by the CK CSS classes and is too wide)
            jQuery('#' + this.domId).css('width', 230);
            // Get the input element
            var theInput = jQuery('#' + this.domId).find('input');
            // Apply the datepicker to the input control
            jQuery(theInput.selector).datepicker({
                showButtonPanel: true
            });

        },
