Cloneing Wicket Objects
Wicketeers,
I was wondering what the best was to duplicate or clone wicket components. I need guidance as to the best way to do this.
I have, on my screen two 'navigation panels' that are identical - one at the top of the page, another at the bottom. They contain dropdown choice fields that, when 'onchange' event occurs, it triggers an ajax request that redirects the user to another page.
As, in order to create the navigation panels - I have to visit the DB, and create them dynamically, so it doesn't make sense to perform this operation twice. Also they generate a large amount of HTML, in order render them, so it seems sensible to do as much as I can on the client side.
The idea was - I generate the components once, and then clone them on the client side. This saves going to the DB twice and rendering them twice. I've attempted to use jquery's clone function as; clone(), clone(true) and clone(true, true) - but none work. The elements are copied, but the ajax actions never execute onchange.
Is there another way to do this that works? A more wicket-centric way?
Cheers,
Col.

Martin,
For some reason JQuery clone doesn't work - even with the withDataAndEvents and deepWithDataAndEvents flags set to true... :/
But - thank you for your suggestion - sounds just the thing - will give it a spin tonight :)
Cheers,
Col.

Hi,
You cannot add a component twice. A component can have just one parent.
I think jQuery clone() should work, but I'm not totally sure.
You can use WicketObjects#clone() method to clone any kind of Object. It uses Java Serialization to do it.
Just make sure you clone it before adding the component to its parent, because the relation will be cloned too.

I stand corrected, Martin is right.
We cache our SQL results hence why this is not a problem for us.

Can't you crate the "navigation panel" once and call add() on it twice by
passing the same reference to it from within your page hierarchy?
On the client side I don't see why you would push this cloning to the
client. Just let the page contain the same panel (html/js) via a single
reference.
You should be fine as long as you handle the db trip in the constructor or
your own "init()" method.
