Igor, I have one more question about IWrapModel : why the Component#defaultModelComparator doesn't check and unwrap IWrapModel before calling the IModel#getObject() ?
private static final IModelComparator defaultModelComparator = new IModelComparator() { private static final long serialVersionUID = 1L; public boolean compare(Component component, Object b) { //final Object a = component.getDefaultModelObject(); // the default model can act as IWrapModel final Object a = component.getInnermostModel().getObject(); if (a == null && b == null) { return true; } if (a == null || b == null) { return false; } return a.equals(b); } }; In the sample above with DDC, if we use the DefaultingWrapModel, defaultModelComparator will always return true (in case of default value selection) and the default model object will never updated because of : Component#setDefaultModelObject(final Object object) // Check whether this will result in an actual change if (!getModelComparator().compare(this, object)) { modelChanging(); model.setObject(object); modelChanged(); } -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/1-4-15-FLAG-INHERITABLE-MODEL-and-default-model-change-tp3252093p3254620.html Sent from the Users forum mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
