[flexcoders] DateField and formatString

[Roman Protsiuk]

Hi, all.

Strange behavior of DateField occurs after changing default value of
formatString (e.g. formatString="MM/YYYY" or formatString="YYYY").
After doing so, selectedDate property of DateField resets to null
every time DateField loses focus.

For example:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute">
    <mx:VBox>
        <mx:DateField id="dateField" formatString="MM/YYYY" />
        <mx:Label  color="blue" text="Date selected:
{dateField.selectedDate}" />
        <mx:Button label="just to click something :)" />
    </mx:VBox>
</mx:Application>

1. select some date
2. click the button
3. result: "Date selected: null"

It is reset to null even when one clicks icon that pops up
DateChooser. I guess this happens when DateField loses focus. But this
is just a hypothesis.

Any ideas why this happens? Solutions maybe?

Thanks in advance,
R.
