Preserve 'selectedItems' after appling 'filterFunction'

Hi,
It seems to me that 'selectedItems' property of a s:List is always emtied
after a filter is applied to its 'dataProvider' by using a custom
'filterFunction'.
Is there a way to preserve the selectedItems?

Or do I have to backup the 'selectedItems' manually in order to re-assign it
after the filter is applied?

Thanks,
Olaf

Thank you, guys!
I will go the way to backup the selected items before filtering.

Thanks,
Olaf

Hello,

I have implemented a similar feature for the DataGrid component. You can
check it here

Thanks,
Ghazi

IIRC, you have to back it up and filter it.  I'm not sure what will happen
if one or more of the selectedItems is no longer in the filtered data
provider.
