Hi !
I gave a look to what Ulrich proposed.
It worked fine.... in one case ...
When the child is included only once in a component.
If it is included several times, the form does not know where each
value is bound.
For example in my formValues dictionary, I have something like this :
0.27.7.1.5.77 = ("http://www.easyshadow.com";);
anotherBindingName1 = ("00", "00", "03", "00", "06", "00", "00",
"00", "40", "00", "30", "00", "23");
And consequently the values for each child components are mixed up :-(
Actually, they all get the value "00"
Is there any way to avoid that?
Do I really need to find a way to make that binding name unique?
Yes, you need to make them unique.

valueForBinding is to talk with the parent of the component.

from StatelessParent.wod
Text1: WOTextField {
text = anotherBinding1;
name="anotherBindingName1"
}
Text1: WOTextField {

name="anotherBindingName2"
}
The stuff should work, but I think it's not a good idea to use
statefull childs when the parent is stateless.
I think it is, in fact, forbidden and WO will give you an error if
you try this.
Right !
That's why I need to have the child stateless because stateless
parent is an AjaxGridNavBar subclass
(WOTextField is a statefull child of StatelessParent in your case).
Hold on Uli. WOTextField is a WODynamicElement and hence stateless.
Ah !
At least I read correctly that part in your book Chuck :-)
