validation is there to make sure the user of the webapp cannot push an
illegal value into a model. it doesnt matter if its just the component
that is being submitted or the entire form. components decide whether

You mean "from getUpdateModel()"? isAlwaysUpdateModel() is called only

I Daniel, how alwaysUpdateModel differs from updateModel? If you have an
required form component that support some clean up logic, it can be coded
inside AjaxFormComponentUpdatingBehavior#onError, and if you need an AJAX
behavior that don't validate the form component, you can
use AjaxEventBehavior

There's no isDisabled in Component, did you mean isEnabled?
How would I have control over individual elements there in that override?

There is a situation when the AjaxFormComponentUpdatingBehavior

How are you storing/retrieving your photos? I recently did some session
size testing and I found the sessions were surprisingly small. Once I
removed the detachable model wrapped around an object holding a photo
(byte array) retrieved from the database my session size shot up
considerably.
Yes, when just using a list of options a dropdownchoice ist the best way!
But in my case I need a dynamic select with optgoups and dynamic options.
My problem is solved now. I found a css error in my code.
The solution works fine now also with firfox!

Problem or bug in Firefox when using a dynamic wicket select component.
Firefox can't handle ListView and right placing of optgroup tags!
Please See following thread:

http://apache-wicket.1842946.
It's working fine with IE, safari, Chrome, Opera but not with Firefox (FF)
The optgroup closing tag is set wrong.
The options are not enclosed in the optgroup tags.
Firebug shows following rendering

Jehan,
It depends on the URL you want to show to the user. If you want a
bookmarkable url, you'll need to use page parameters. If the url doesn't
matter to you, you can simply pass in parameters to the constructor of
the other page, and then call setResponsePage( ).

Hi Jehan,
You'll need to provide your TextField with a model where it can
load/store it's value.
This is easy to do:
new TextField("atext", Model.of(""));
