Cool - I will try this .... I had tried the visible="false" but I left it in the Layout. After further investigation I narrowed this down to the fact that I am using the advanced datagrid footer extensions that are available - Alex's I think with a couple of tweeks - and the error is in AdvancedDataGridBaseEx.as/protected function drawColumnBackground where var lastRow:Object = rowInfo[listItems.length - 1]; resolves to null and causes problems downstream when calculating height .... includeInLayout = false will be a lot easier than resolving the above ... fingers crossed.
