             Summary: Error in DataGrid getHeaderRendererAt(-1)
                 Key: FLEX-35028
                 URL: https://issues.apache.org/jira/browse/FLEX-35028
             Project: Apache Flex
          Issue Type: Bug
          Components: Spark: DataGrid
            Reporter: Judah Frangipane


When using a DataGrid if you click the header and the column index is -1 then an error is thrown: 

[code]
    public function getHeaderRendererAt(columnIndex:int):IGridItemRenderer
    {
        // TODO: fix this: do the work here, rather than the layout            
		const view:Group = getColumnHeaderViewAtIndex(columnIndex);	
        return GridHeaderViewLayout(view.layout).getHeaderRendererAt(columnIndex);
    }
[code]

view is null

Solution may be to check if index is not -1 and return null if it is
