Hi,
first of all. Thanks for your help. This version seems much easier and
clearer to me. But still I do not now where to validate the input of the
field. Should I use the wicket validators? I'm not so familiar with that.
Would be kind, if you could give me one or two more hints! The models
returns valid on startup. So the textfield is green. :-( How do I change the
value returned by the isValid() method? Could you give me a hint, how to
check for "Cliff" e.g.?
If I add this line to my code it works fine.
target.appendJavaScript("document.getElementById('" + uname.getMarkupId() +
"').focus();");
But I'm still trying to use your code as it seems to me cleaner.
final TextField usernameField = (TextField) new TextField("username", new
PropertyModel(this, "username"));
usernameField.add(new AttributeModifier("class", true, new Model() {
public Object getObject(Component c) {
return usernameField.isValid() ? "valid" : "invalid";
}
}));
usernameField.add(new
AjaxFormComponentUpdatingBehavior("onkeypress") {
public void onUpdate(AjaxRequestTarget target) {
if(!usernameField.isValid()) {
target.appendJavascript("document.getElementById('"
+usernameField.getMarkupId() + "').focus();");
}
target.addComponent(usernameField);
}
});
Thanks once again in advance!
Cliff

Hi Cliff,
If I read your requirements correctly you should use "onkeypress"
instead of "onblur". But I guess you already guessed that.
Regards,
Erik.
