> DojoAjaxResponseBuilder uses the client id of a component to determine
> whether or not to render it (see the contains method). Form components
> (children of AbstractFormComponent) will always have a null client id at this
> point & hence will never be rendered.
> The form components seem to have a null client id because
> AbstractFormComponent has an abstract setClientId method. This causes
> tapestry to add a generated getClientId method that overrides the
> AbstractComponent.getClientId method. If you look at a form component in a
> debugger you can see the extra $clientId member variables that have been
> added to the concrete class.
> The AbstractFormComponent setClientId method is only invoked by
> renderIdAttribute. Obviously this happens after the DojoAjaxResponseBuilder
> calls getClientId to determine whether the component should be rendered.
> I think this can be fixed by removing the AbstractFormComponent setClientId
> method & adding a protected setClientId method to AbstractComponent (that
> just sets the _clientId member).
> This will result in DojoAjaxResponseBuilder calling
> AbstractComponent.getClientId & being returned the bound id or the
> IComponent.getId. Either of which should allow it to properly determine
> whether the component is supposed to be rendered or not.
