I have a scrollable data table inside a scrollable modal panel. Whenever I scroll down the modal panel scrollabledatatable alignment is getting lost. I have attached screen shots from my application. In the first image, you can see how the data table aligns perfectly when there is no scrolling. In the second image, alignment is lost (look at the header and body divs of scrollable data table) when the modal panel is scrolled to bottom. This is a problem only in IE8 and it works fine in FF and Chrome. I am using richfaces 3.3.3. Please let me know how to solve this issue or a work around that I can use.
