Stateless AJAX in Wicket
All,
I've done a small experiment with stateless ajax based on the code
from Jolira and ported it to wicket 7.
It appears that stateless ajax actually works, and the code doesn't
look all that jarring to me. I understand that providing this
out-of-the-box, and as a default implementation is dangerous.
https://github.com/jolira/wicket-stateless/blob/master/stateless/src/main/java/com/google/code/joliratools/StatelessAjaxFormComponentUpdatingBehavior.java
The only thing I had to fix was adding the following onBind method,
because Wicket's standard implementation doesn't perform this when
getStatelessHint() returns true:
@Override
protected void onBind()
{
super.onBind();
getFormComponent().getBehaviorId(this);
}
The other snag I ran into was that the components you want to replace
need to have a static markupId (not generated by Wicket).
Is this something we want to add to wicket proper?
Martijn

Yes, Jolira's code has been moved to Wicketstuff in early 6.x days.
Stateless Ajax works for the simple cases but would fail for the use case
I've explained here: http://markmail.org/message/d7xuiao44owuyf56. Although
I guess the same is valid for non-Ajax stateless link too.

I think this code has been already integrated into wicketstuff module
stateless : https://github.com/wicketstuff/core/tree/master/stateless-parent

The idea is not new. It just needs someone to push it!

In any case, +1 to add stateless AJAX to Wicket. I think it would be
appreciated.
