Personalization: Property with type="Date" doesnt work

Hi,

I am trying to personalize a property whose type is Date.

<property name="DoB" value="19820117">
            <property name="Personalization" value="dialog"/> 
            <property name="type" value="date"/> 
</property>

Though i get the calendar icon and am able to <b>personalize</b> the property, the value doesn't reflect when i try to write it using response.write(). Its always "19820117".

What could be the issue? I have another property with type=String and it works as expected.

Thanks,

Shruti
