2 Grids Set with % Width: IE Issue

Having an issue when displaying two grids on a single page each with their widths set to a percentage. Our application originally was coded to have these two grids at a fixed size. The customer has now requested they size with the browser window. The issue in IE is when the page is resized, the contents of the last rendered grid are the only ones repainted. The contents of the top grid act as if the grid size has not changed.

To run a simple test, I found a simple two grid example (code below)provided by Alex from the following post:

http://www.activewidgets.com/javascript.forum.10849.4/help-have-2-grids-need.html

Environment: IE 6.0, AW 2.0.2

When I run this code, I see that the horizontal scroll bar acts in one of two ways:
1) If the horizontal scrollbar is needed when the grid first draws, it will never be removed even if all columns are displayed
2) If the horizontal scrollbar is not needed when the grid first draws, it will never be displayed.

This problem is compounded more when I add the DOCTYPE:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

This DOCTYPE is required for our development. With this DOCTYPE, the full issue kicks in. When I run this code and I resize the window, the contents of the top grid do not repaint the same way the bottom grid does.

Example code from mentioned post:

I tested your code with AW 2.5.1 (since I don't have 2.0.2 installed), and against IE, Netscape and FF.

The same issue happens with IE exactly as you described but with Netscape and FF, both the grids act like the top grid in IE. Neither grid will display a horizontal scrollbar if the page is reduced in width. If I do a refresh while the page is smaller, the scrollbars appear but both do not disappear when the page is expanded to its full width.

I also tried with a smaller percentage width and also changed the height to a percentage. No change in behaviour was observed. The same occurs with just one grid in FF and Netscape. IE seems to handle it OK. So its definitely a bug of some sort.

This is a bug in AW 2.0.2 (and 2.5.1).

Here is a patch for 2.0.2 -

new AW.Scroll.Bars;
var scroll = AW.Scroll.Bars.prototype;

scroll.setEvent("onresize", function(){

    this._serial = ((this._serial||0) + 1) % 1000;
    var s = this._serial;

    this.setTimeout(function(){
        if (s == this._serial) {
            this.raiseEvent("adjustScrollBars");
        }
    });
});


And also the similar patch for 2.5.1 -

new AW.Scroll.Bars;
var scroll = AW.Scroll.Bars.prototype;

scroll.setEvent("onresize", function(){

    if (!this._initialized){
        return;
    }

    this._serial = ((this._serial||0) + 1) % 1000;
    var s = this._serial;

    this.setTimeout(function(){
        if (s == this._serial) {
            if (this.element()) {

                var w = this.element().offsetWidth;
                if (w != this.getContentProperty("width", "total")) {
                    this.setContentProperty("width", w, "total");
                }

                var h = this.element().offsetHeight;
                if (h != this.getContentProperty("height", "total")) {
                    this.setContentProperty("height", h, "total");
                }
            }
        }
    });
});
