Hi, in https://issues.apache.org/jira/browse/WICKET-6348 the way how to react on onSelectionChanged(Object object) got changed to now a usage of
// Wicket 7.x new CheckBox("id", model) { protected boolean wantOnSelectionChangedNotifications() { return true; } protected void onSelectionChanged(Boolean newSelection) { // do something, page will be rerendered; } }; // Wicket 8.x new CheckBox("id", model) .add(new FormComponentUpdatingBehavior() { protected void onUpdate() { // do something, page will be rerendered; } protected void onError(RuntimeException ex) { super.onError(ex); } }); My Problem is now that I try to get brix cms to compile and I have a code in there as: form.add(new DropDownChoice<String>("tileType", new PropertyModel<String>(this, "newTileTypeName"), new TileTypeNamesModel(), new TileTypeNameRenderer()) { private static final long serialVersionUID = 1L; [....] @Override protected void onSelectionChanged(String tileTypeName) { [...] } }.setRequired(true)); How can one access the String tileTypeName now in usage of the new FormComponentUpdatingBehaviour as the onUpdate there has no parameter at all ???
