Maybe use an IRequestCycleListener and maybe use onRequestHandlerExecuted.
See
private void execute(IRequestHandler handler)
{
Args.notNull(handler, "handler");
try
{
listeners.onRequestHandlerResolved(this, handler);
requestHandlerExecutor.execute(handler);
listeners.onRequestHandlerExecuted(this, handler);
}
catch (RuntimeException e)
{
IRequestHandler replacement = requestHandlerExecutor.resolveHandler(e);
if (replacement != null)
{
execute(replacement);
}
else
{
throw e;
}
}
}
Ajax request handler has a
@Override
public final Collection<? extends Component> getComponents()
{
return responseObject.getComponents();
}
