Title: setSelectedIndices on list troubles
I am trying to debug a Flex 4 application by other developer(s). I need to set the selected indices for a list. I have a sub-class to do the work. I have tried all forms of commands to set selected indices but nothing actually writes, even setting selected indices to null. Here is some code:
import mx.core.mx_internal;
use namespace mx_internal;
trace ("last indices: " + _lastSelectedIndices_vector);
//trace shows the values in the vector (created and populated elsewhere)
trace ("current selected indices: " + selectedIndices);
//trace shows data provider currently selected indices values
mx_internal::setSelectedIndices (_lastSelectedIndices_vector, false);
trace ("new selected indices: " + selectedIndices);
//trace shows same values as current selected Indices (no change)
I have also tried:
selectedIndices = _lastSelectedIndices
and many other tweaked attempts. All to no avail. Documentation and many examples from the web show that this should work.
Please help me set selected indices!

try passing a hard coded array to see if you are setting indices at the right place.

it seems that the indices are being set before its being actually populated.

Thanks for your thoughts. I tried assigning null and a fixed array but neither change the selected indices (for which values do already exist and can be read via trace just before and just after = same). Assigning the data provider happens elsewhere and is already done when this code runs.
