Can not do resizable in a resizable div

When I have a resizable div and want to create a resizable div inside it.

the resizable function does not work.

Here is the original code:

this._renderAxis = function(target) {
    target = target || this.element;
    for(var i in this.handles) {
        if(this.handles[i].constructor == String)
            this.handles[i] = $(this.handles[i], this.element).show();

The code:

this.handles[i] = $(this.handles[i], this.element).show();

Which I think should be changed to:

this.handles[i] = this.element.children(this.handles[i]).show();

otherwise the handles will include all children handles.

If you want me to do a demo, I can demo it for you.

Thanks
