Flex Datagrid - headerRenderer Combobox problem

[lacus]

Hi all,

I would like to make an editable datagrid with filtering in the header.

The filtering width TextInput control works fine, but I want to filter with ComboBox too. And I can't make work the ComboBox.

Problem with the ComboBox:
if you click anywhere in the datagrid to edit an item, the value of datagrid will be set to default (to the first item in the ComboBox), further I don't now, how I get the value of this header datagrid.

Any idea?

See this example, it uses NumericStepper instead of ComboBox, but it shouldn't be much of a difference.

I've seen this example, but there is the NumericStepper Component in the DataGrid and not in the DataGrid header. It's all right setting a ComboBox in the grid or in the header.

My problem is, if I change the value in the header ComboBox and I click after any editable item in the grid, the comboBox change to his first item. Try the first link I've given and you can see it.

I'm getting error in your first example...
