in ConfrimPanel, ajax of cancel button want replace its parent [it's
ConfrimPanel] with person panel
public ConfrimPanel(final String id, final MarkupContainer row,
final Person person) {
super(id );
setOutputMarkupId(true);
add(new AjaxFallbackLink("ok") {
public void onClick(final AjaxRequestTarget target) {
Application1.getPersons().remove(person);
target.addComponent(row.getParent().getParent());
}
});
add(new AjaxFallbackLink("cancel") {
public void onClick(final AjaxRequestTarget target) {
PersonPanel personPanel = new PersonPanel(id, person);
// reuse a same id for two panel.
row.replace(personPanel); // replacing, call
page.componentRemoved(aConfrimPanel);
target.addComponent(personPanel);
}
});
}
on AbstractDefaultAjaxBehavior
public final void onRequest() {
...
finally
{getComponent().getPage().setVersioned(isPageVersioned); }
getComponent() = aConfrimPanel
getPage() = null
maybe i missing things but wicket tell :
ERROR RequestCycle - No Page found for component
[MarkupContainer [Component id = cancel, page = <No Page>, path =
person_or_confrim:cancel.Home$ConfrimPanel$2]]
