[flexcoders] Re: Beta3 Please Help

Hello Gordon,

Some Update:

I found that when I compile only the MyTable.as file, nothing shows up.  When I wrap it in an mxml file, then it works.

----- TestMain.mxml -------
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" width="100%" height="100%"xmlns="*">
    <MyTable />
</mx:Application>

------------------

Essentially, my real app has the following format.

TestMain.mxml calls MyTable, and MyTable calls MyTable1 (which is the same structure as MyTable). 

MyTable1 is called in MyTable.as file: ---------

    override protected function updateDisplayList(unscaledWidth:Number,
    unscaledHeight:Number):void {
    super.updateDisplayList(unscaledWidth, unscaledHeight);
    // Check to see if style changed.
    if (bFillColorsChanged==true)
    {
    // Redraw gradient fill only if style changed.
    fillColorsData=getStyle("fillColors");
    graphics.beginGradientFill(GradientType.LINEAR, fillColorsData,
    alphas, ratios);
    graphics.drawRect(0, 0, unscaledWidth, unscaledHeight);
   
    var table1:MyTable1 = new MyTable1();
    addChild(table1);
    }
--------------------

It seems to me that the problem I am having in Beta3 is due to the fact that Beta3 doesn't show the MyTable.as file by itself, it only works when wrapped by an mxml file.

I hope that this situation has an easy solution as the comp0nent I have been building took a while to make and a big change would be a bit of a disaster.

Thanks again for helping out on this.  Definitely Appreciated Big Time.

Cheers,

Tim
