That will work, but it is not very elegant to put a reference to the page or panel into the model. He probably should not overwrite the reference on "selectedEintrag" or use the readonly model you suggested. I think I would put a new Model() into the label and then, instead of overwriting the variable "selectedEintrag", call label.setModelObject(item.getModelObject().getVorname()) - -- Regards, Hans http://cantaa.de -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/update-label-using-Ajax-Link-tp3356575p3357001.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

Yes you are right... but I think new PropertyModel(this, "selectedEintrag.vorname") will work I guess.

Re: update label using (Ajax)Link
Sorry @ all, I just forgot to restart the server so the approach with the AbstractReadOnlyModel is working! Thanks. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/update-label-using-Ajax-Link-tp3356575p3356773.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
Re: update label using (Ajax)Link
Thanks Ernesto for you quick reply. Unfortunatelly this is not working :( But if I debug within the onClick method of my AjaxLink item.getModelObject() returns null? Any idea why this happens? Or is this just a problem with my debugging configuration of eclipse? I would expect I can access "Eintrag" within the onClick method by using item.getModelObject()?

Re: update label using (Ajax)Link
I think you label model is never "updated".Can you try
final Label vorname = new Label( "Vorname", new
AbstractReadOnlyModel() {
private static final long serialVersionUID = 1L;
public String getObject() {
return selectedEintrag.getVorname());
};
});
or
final Label vorname = new Label( "Vorname", new
PropertyModel(selectedEintrag, "vorname"));
Regards,
Ernesto

update label using (Ajax)Link
Hi,
I try to update a component ("vorname" within my example) once the user
click on a link within a table.
(In fact it doesn't matter if it is an ajax link or a "normal" one. My
example is using an ajax link.)
This im my JAVA code:
public class Test extends WebPage {
private Eintrag selectedEintrag = new Eintrag();
public Test( PageParameters parameters ) {
ArrayList listEintraege = ladeEintraege( parameters );
final Label vorname = new Label( "Vorname",
selectedEintrag.getVorname()
); //just empty in first instance
auswahlVorname.setOutputMarkupId( true );
add( auswahlVorname );
add( new ListView( "List", listEintraege ) {
protected void populateItem( final ListItem item ) {
Eintrag eintrag = item.getModelObject();
item.add( new Label( "Info", eintrag.getInfo() ) );
item.add(new AjaxFallbackLink("Details_Link"){
@Override
public void onClick( AjaxRequestTarget target ) {
selectedEintrag = item.getModelObject();
target.addComponent( vorname );
}
});
}
});
}
}
Can anybody provide me some information's why this is not working (no update
at all)?
Isn't it possible to bind my Label component to a private property and
update this property during the onclick method?
Thanks in advance.
