Thanks for all your answers.
I tried your solution Thiago like this:
BeanModel<MyObject> getModel() {
return
beanModelSource.createDisplayModel(myObject.class,resources.getMessages());
}
And by removing:
@Property
private BeanModel< MyObject > model;
But then I get: ...pages.Index does not contain a property (or public field)
named 'model'
The solution I found was to define my model two times:
@BeginRender
public void begin() {
model = beanModelSource.createDisplayModel(myObject.class,
resources.getMessages());
}
And in
@OnEvent(value="success", component = " myForm ")
public void processForm() throws Exception {
myObjects = ...
model =
beanModelSource.createDisplayModel(myObject.class, resources.getMessages());
...
ajaxResponseRenderer.addRender("myZone ", myZone.getBody());
}
I guess it's not really clean to define it two times...
I m using Tapestry version 5.3.3
Thx
Christophe

Hi!
Your code is missing that part that provides the value for myObjects and what
Tapestry version you're using. In addition, you seem to be only setting the
model field when rendering the whole Grid. Why don't you remove the model field
and replace it with this:
BeanModel<MyObject> getModel() {
return
beanModelSource.createDisplayModel(myObject.class,resources.getMessages());
}
This will make sure the model passed to Grid is never null.
