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.
(WOTextField is a statefull child of StatelessParent in your case).
Hold on Uli. WOTextField is a WODynamicElement and hence stateless.

Unfortunately, this is still not the pattern I have (sorry for
being unprecise)
I rather have :
from StatefulParent.wod
StatelessParent: StatelessParent {
XYZ = "foo";
}
from StatelessParent.wod
Text1: WOTextField {
text = anotherBinding1;
}
Text2: WOTextField {
text = anotherBinding2;
}
Text3: WOTextField {
text = anotherBinding3;
}
And then in StatelessParent I use the 3 bindings to give back a
value to StatefullParent using setValueForBinding
The problem is that anotherBindingX are never set by the text
fields and if I do hasBinding("anotherBindingX") in
takeValuesFromRequest I get a false answer
Does it seems behavior to you?

During the takeValuesFromRequest
Another option is to use the ^ (carat) binding in your component
and forget the stuff in the StatelessParent.java
For instance:
from StatefulParent.wod
StatelessParent: StatelessParent {
XYZ = "foo";
}
from StatelessParent.wod
Text: WOTextField {
text = ^XYZ;
}
^ is the same as "bound against my parent". ^ doesn't work for
stateful components
Good luck

Just what I thought.
The problem is it does not work :(
In which phase do you do that?
Does it work for child components too?
I have something like this :
StatefulParent contains StatelessParent contains TextFields
I use bindings to get the bindings StatefulParent sets. Works fine.
But when StatefulParent submits a form, the values of the text
field does not seem to reach StatelessParent
Any idea of what I did wrong?

Hi !
If I have a stateless component (no variable synchronization)
that has for example text fields in it, it seems I never get
the values of my text fields in my stateless component. I
suppose they are not pushed to the parent since it has no
automatic synchronizaion.
Is there a way to manually get those values during the R-R loop ?
Or I'd better turn automatic synchronization on again keeping
my component stateless (I need it stateless)?
