No, nothing of that kind. It's just a helper to make sure noone
uses Ajax on components which are added to the markup as
"<wicket:container wicket:id="...">...</wicket:container>...".
The code goes like this:
| public class WicketContainerChecker implements
IComponentInstantiationListener {
| private static final Behavior BEHAVIOR = new Behavior() {
| private static final long serialVersionUID = 1L;
|
| @Override
| public void onComponentTag( final Component component, final
ComponentTag tag ) {
| if ( tag instanceof WicketTag && "container".equals(
tag.getName() ) && component.getOutputMarkupId() ) {
| throw new IllegalStateException( "Component " + component + "
requests a markup id (" + component.getMarkupId() + ") but is attached to " +
tag
| + "! This will not work in deployment mode!" );
| }
| }
| };
|
| @Override
| public void onInstantiation( Component component ) {
| component.add( BEHAVIOR );
| }
| }
Cheers,
