[flexcoders] testing object equality in datagrid AFTER sort

2008-04-11 Thread Amy 
Hi,

I have a datagrid with selectable set to false.  I'm listening for a
double click event which then executes the following:

dg.selectedItem = e.itemRenderer.data;

This works fine when the datagrid is first loaded.

After I sort the datagrid, the same line of code always results in
dg.selectedItem being set to null.  

My working theory is that there's some effect on object equality
occurring with the sort??  Reference

I've tried implementing the IUID interface as suggested by Adobe but
with no luck.

Does anyone have any solution or ideas to point me in the right direction?

Thanks,
Amy

When a sort is applied, the datagrid asks the sort to find the object.
It must not be finding the object somehow.  Do you have a simple test
case you can post?
