[Moo] [Drag.Move] offsetParent null with IE

[Andrea Dessì]

Hi all,

playing a bit with Drag.Move and I'm getting
"offsetParent is null or is not an object" when setting the container
to
the Drag.Move istance:

Example:
http://mootools.net/shell/PLfcD/

The null offsetParent is in the calculateLimit function:

calculateLimit: function(){
        var offsetParent = this.element.getOffsetParent(),
        containerCoordinates = this.container.getCoordinates(offsetParent),
        containerBorder = {},
        elementMargin = {},
        elementBorder = {},
        containerMargin = {},
        offsetParentPadding = {};

        ['top', 'right', 'bottom', 'left'].each(function(pad){
                containerBorder[pad] = this.container.getStyle('border-' +
pad).toInt();
                elementBorder[pad] = this.element.getStyle('border-' + 
pad).toInt();
                elementMargin[pad] = this.element.getStyle('margin-' + 
pad).toInt();
                containerMargin[pad] = this.container.getStyle('margin-' +
pad).toInt();
                offsetParentPadding[pad] = offsetParent.getStyle('padding-' +
pad).toInt();  /////error here!
        }
}, this);


So the error seems to happen beause IE cannot recognize "offsetParent"
as an html element.
Can you confirm this problem? :)
