(ZK 7) Auto fill no binding my data (MVVM and composer) - mvvm

Question

I have a kind of bug with zk 7 with auto fill of chrome :(
Auto fill fills the fields in my web page (textbox) but the fields of my view-model stay empty with chrome.
For example, with an address form autofilled all data is null in my viewmodel (not in my textbox on the webpage)
If I simulate an event 'onChange' my binding works.
(zAu.send(new zk.Event(zk.Widget.$('$idOfMyTextBox'),"onChange",{'value':'test!!','start':6})) )
The problem is the same in a new zk project with one mvvm page.
Does anyone have a solution ?
Thanks for you help :)
Edit : An Exemple
I write my name and with Chrome by auto fill other fields are completed.
Screen of form auto filled
And the result is :
Name : Pigeon
First name : null
Address : null
Postal code : null
City : null

My view model
public class MyViewModel {

private String prenom;
private String ville;
private String adresse;
private String codePostal;
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public String getPrenom() {
return prenom;
}
public void setPrenom(String prenom) {
this.prenom = prenom;
}
public String getVille() {
return ville;
}
public void setVille(String ville) {
this.ville = ville;
}
public String getAdresse() {
return adresse;
}
public void setAdresse(String adresse) {
this.adresse = adresse;
}
public String getCodePostal() {
return codePostal;
}
public void setCodePostal(String codePostal) {
this.codePostal = codePostal;
}
#Command
public void launch(){
System.out.println("Name : "+nom);
System.out.println("First name : "+prenom);
System.out.println("Address : "+adresse);
System.out.println("Postal code : "+codePostal);
System.out.println("City : "+ville);
}
}
May be a configuration on zk.xml for force zk to reading the dom ?

Answer 1

The best way to save your data from form to view model is to separate the bind from your zul
example for the first name textbox:
<textbox value="#load(vm.prenom) #save(vm.prenom, before='launch')" />
if you do this for all your textboxes, you will spare alot of client/server comunications and I think it'll work for your case
