CF8 cfchart and ajax

I am having trouble with charts that are embedded either in <cfdiv bind> or <cflayoutarea source=...> statements. If the charts are generated in a standalone page, they provide the mouseover display of the label and value of the chartitem. Once I embed these charts into a ajax layout page, the mouseover results in IE6.x object error. When I run the page with cfdebug, I get "window:global: Object expected " when I mouseover the charted item.

Any suggestions on what I am doing wrong?

Thanks,
