Try FormProxyObject in stead of Form

Still returns Null

it would really be helpful if you could post a runnable and isolated example. just showing the problem. Posting the whole zul file which isn't runnable at all won't make it easier to get help efficiently

apart from that, please always state the ZK version.

Hi Senthil,

thanks for a working example. Everything works as expected the parameter "form" is not passed as a NULL reference. I got the actual form proxy instance:

To debug a bit better here 2 amended methods to give additional debug information:

@Command("cancel")
@NotifyChange("currentInsurance")
public void onCancel(@BindingParam("form") Insurance form) {

// Messagebox.show("Form Object " + form); Messagebox.show("cancelled REAL Object " + this.currentInsurance + " : ignored values " + form.getCode() + ", " + form.getName()); }

@Command
public void save() {
    Messagebox.show("saved REAL Object " + this.currentInsurance);
}

when you previously called Messagebox.show("Form Object " + form); it didn't output "Form Object null" but instead it returned "Form Object form null - null" where "null - null" is the result of your toString method, which doesn't work in a proxied instance. You cannot access the instance variables directly, if you want this to work implement the toString as follows:

@Override
public String toString() {
    return this.getCode() + " - " + this.getName();
}

then the form proxy can call the proxied methods getCode and getName to resolve to the value in the cache.

My Opinion on New Form Binding is : ZK Team killed the Form Binding design in ZK 8 by disturbing too much on the domain module side.

I am sure, if i go forward on ZK 8, i will face lot of problems due to this proxy issues. And also you should have two options : Use ZK 7 style and Use ZK 8 proxy style. So that old customers will be happy.

if I use this toString implementation in your example it works:

@Override
public String toString() {
    return this.getCode() + " - " + this.getName();
}

I don't know again what you are doing differently, for me the form binding works as expected.
