Finally I got it.
If you add setType( String.class ) to your TextField the
EmailAddressValidator triggers on null/empty input. If you leave this

I thought it would be useful to declare my inputfields as a certain type.

I'm totally missing the forest through the trees...so I tried to reduce the
example to the very minimum. Maybe someone can provide me an idea how to
deal with my issue?!

Hi all,
I try to store data within my database using JDO but I get the following
exception: ...is managed by a different Object Manager. So I tried a view

First of all here are my POJOs

Meanwhile I tested a bit more and you really can reduce the example of
eager/lazy-loading.
After using Google a while I tried to add

to my POJO.
But now I get the following (console) output: WARN [DataNucleus.MetaData]

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 {
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

I just forgot to restart the server so the approach with the

Thanks.

Hi,
how can I display navigation points and page content depending on the login
status?
I have a login box and only after a sucessfully authentication I want to
1.) extend the existing navigation
2.) make content visible on (already) public sites
Seems like I have to create my own Session
Meanwhile I already implemented the part if there is a visible link to a page
that requires authentication the user get's redirected to the login page.
But how can I make links invisible if a user is not logged in?

Hi all,
let's assume there is a form with an input field an two buttons: submit and
reset.
Within the java code I add a new form component (extends Form) with an input
field and implement the onSubmit() method.

more stuff
Meanwhile I tried to add another submit button and just labeling that as a
reset button.
This is almost working but after calling the onSubmit method of my reset

Hi all,

(AuthenticatedWebSession) and all my secure java files are marked with

So once I added this annotation there is no chance to bypass the
authentication.
But what if there is the need to be
it's not about to bash the framework.
Because I'm still a beginner I just want to make sure that this approach is
not working for me. It seems like the demo implementation just allows two
options:
- need authentication
- don't need authentication
but there is no option to make it more flexible.

Hi all,
at the moment I have a modal window with a link in it.
If I click the link (it's a BookmarkablePageLink) the new page get's loaded

ok - I just realised that the WindowCloseCallback method gets triggered if a
user clicks on the link but also if he wants to close the popup. That's not
that good :(
Is there a chance to differ whether the user uses the link or just click on
the x button to close the popup?
