---------------------------------------
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
