> In wicket 1.2.5, is not possible (at least I didn't manage to find a way) to add AjaxIndicator image to a page for all Ajax requests made by its child components.
> Currently, the AbstractDefaultAjaxBehavior has a findIndicatorId() method which is responsible to find the component id which should be Ajax indicator.
> [code]
>         private String findIndicatorId() {
>                 if (getComponent() instanceof IAjaxIndicatorAware) {
>                         return ((IAjaxIndicatorAware)getComponent()).getAjaxIndicatorMarkupId();
>                 }
>                 if (this instanceof IAjaxIndicatorAware) {
>                         return ((IAjaxIndicatorAware)this).getAjaxIndicatorMarkupId();
>                 }
>                 return null;
>         }
> [code]
> Wouldn't it be better if instead of checking only if :
> - the getComponent is instance of the IAjaxIndicatorAware interface, the check would be made up in hierarchy to find the first parent which implements the IAjaxIndicatorAware interface?
> Thus, if my page implements the IAjaxIndicatorAware interface, it will indicate any ajax requests of its components... exact what I need right now.
