RE: [flexcoders] combobox selectedIndex

Shlomi,
 
One possibility is that you are setting the index of the combobox before the databinding fires.  Thus:
 
1.  It attempts to set the index to 2.
2.  It sees the dataprovider has length 0.
3.  It silently fails at runtime.
 
some time goes by
 
4.  The dataprovider is populated by databinding.
 
You might want to try this:
 
    private function getMySelectedIndex(intervals:Object):Number
    {
   
        return(2);
 
    }
 
 
 
<mx:ComboBox id="intervalCMB" dataProvider="{intervals}" selectedIndex="{getMySelectedIndex(intervals)}"/>
 
When 'intervals' changes it fires off a call to the local function getMySelectedIndex via databinding.

Shlomi,

There's nothing wrong with the code that you have posted below.
Only reason why I think this would not work is if you have only 2 items in the ComboBox!

If not, try this as well
<mx:ComboBox id="intervalCMB" dataProvider="{intervals}" initialize="intervalCMB.selectedIndex="2" />
