DropDownChoices Removing "Choose One" after Ajax Call
I have a dropdownchoice component on my page and according to some selections
on my page, this component is updated by a ajax call.
At the beginning it displays the choices without showing "Choose One" but
after ajax call it displays "Choose One". I know this issue is coming from
any of the choices are not selected right there but I don't know how to say
the component choose first one as selected for not displaying "Choose One".
Can you suggest any solution for this?
With my best regards.

The component will select the item that your model provides. If your model's object is not set, the component will not select anything. It would be crazy to think that the component should have an element selected that wasn't actually the model's object.
So, if you want to select the first element, set your model's object to it.

xFlasH thank you for your suggestion but it removed Choose One but added a

Hi,
How about setNullValid(true) on the DropDownChoice ?
