Description

Wicket version 9.0.0.M2 and 8.xx with Fast2WicketSerializer

When Session.get() is called in a non serialized object
and session.getMetaData(MetaDataKey) is in a serialized object
there is a StackOverflowError

Will produce a StackOverflowError:

@Override
protected void onInitialize() {
  super.onInitialize();

  Session session = Session.get();

  add(new AjaxLink<Void>("link") {
    @Override
    public void onClick(AjaxRequestTarget target) {
      Boolean showgrid = session.getMetaData(KeyGrid);
      // ....
    }
  });
}

 

Will not produce:

@Override
protected void onInitialize() {
  super.onInitialize();

  add(new AjaxLink<Void>("link") {
    @Override
    public void onClick(AjaxRequestTarget target) {
      Boolean showgrid = Session.get().getMetaData(KeyGrid);
      // ....
    }
  });
}
