Interface IProviderStylePropertyChanges

public interface IProviderStylePropertyChanges

Implement this interface if wicket component/bean wants to update itself in the browser through ajax requests. Servoy will call getStylePropertyChanges() on every ajax request (user action or ajax poll) to test if this component is changed and wants to update itself.

Wicket components that implements this interface should call Component#setOutputMarkupPlaceholderTag(boolean) with true. So that wicket ajax can replace/update the component. and override the getMarkupId() so that the right servoy markupid is generated:

        public String getMarkupId()
        {
                return WebComponentSpecialIdMaker.getSpecialIdIfAppropriate(this);
        }
