Invalid Argument in onScrollHeightChanged

Hey all,
I have been using ActiveWidgets for this Struts project, but have not seen an error like this before. I am sure it is me doing something stupid.
When the grid loads, I get a javascript error that says "Invalid Argument".
If I trace it back, It brings me to this line:
var e = this.getScrollTemplate().element();

in this function:
onScrollHeightChanged:function(h)
 	{
 		var e = this.getScrollTemplate().element();
 		if(e)
 		{
 			e.firstChild.firstChild.style.height = h + "px";
 			if(AW.ie)
 			{
 				e.firstChild.className += "" 
 			}
 		}
 	}

in
AW.Grid.Controllers.Overflow

in aw.js.

Any idea where this is called from/why I am getting this error?

This might happen if h argument is not a valid number (or is negative). In this case

e.firstChild.firstChild.style.height = h + "px";

will fail with this error. I suspect the negative value for h but I don't know why it happens.

When is this method called? Perhaps I am invoking it before the height is initialized?

I have 2 grid son the same page...would that affect it at all?

onScrollHeightChanged event handler fires whenever setScrollHeight() method is called. It is called internally from adjustScrollHeight method (during initialization or when changing row height etc.).

I tried debugging it, and it says that the value of 'h' is 'NaN'. Any thoughts?

I guess what I don't understand is why this is happening on this page and not my others, when I don't even know what I am doing to make this variable Not a Number.

Dammit. If I told you I was being an idiot, would you believe it?

Note to self: Set row count to DATA.length not GRID.length!
