-----------------------------------------

Hi,

as Martin suggested I also prefer to implement an AJAX listener to provide such 
feature. Here is a first implementation:

{code:java}
public class AjaxDisableComponentListener extends AjaxCallListener 
{
    /**
     * 
     */
    private static final long serialVersionUID = -3772784701483881109L;
    private static final String DISABLE_ENABLE_JS = 
";document.getElementById('%s').disabled = %s;";

    @Override
    public CharSequence getBeforeHandler(Component component) 
    {
        return String.format(DISABLE_ENABLE_JS, component.getMarkupId(), true);
    }
    
    @Override
    public CharSequence getCompleteHandler(Component component) 
    {
        return String.format(DISABLE_ENABLE_JS, component.getMarkupId(), false);
    }
}
{code}

Those who need also an indicating picture can use AjaxIndicatorAppender.

> Wicket should provide a Behavior that can be assigned to (Ajax)Buttons and 
> when clicked those buttons should be disabled via the HTML "disabled" 
> attribute.
> For AjaxButtons the behavior should re-enable the button after processing the 
> Ajax response.
> 1)Run the app
> 2)Click "submit" quickly several times
> 3)Watch the console
