[Seaside] Image Zoomer: How to capture mouseOver X & Y

[Robert Sirois]

Yay! Thank you so much. I really appreciate you keeping up with the mailing list.

This has the correct javascript output:

        onClick: (
            html jQuery ajax
                callback: [:value | self session mousePosTop: value] value: (JSStream on: 'arguments[0].pageY');
                callback: [:value | self session mousePosLeft: value] value: (JSStream on: 'arguments[0].pageX')
        );

Thanks!
RS
