AJAX and Components Hierarchy
Hi,
I'm implementing some Behaviors in a complex page which contains many panels
and components most of them nasted.
Exactly now, I'm adding a behavior to a button to change the model of the
entire component
Then I want that the component reload the model and performe the changings
Inside a AjaxFormComponentUpdatingBehavior I do this:
ajaxRequestTarget.addComponent(mainComponent)
It works fine and the main component change properly.
The problem I get now is that also every child components (DropDownChoice
ecc...) change and reload the model .
In this way every user selection is lost.
Is there a way to let just the main component change and not his child
components?
Once again thanks a lot for any suggestion.
Andrea

sounds like you are reusing the model instances? if you do not want the
change to propogate then simply clone the model before passing it on to a
child
so instead of
class mypanel extends panel {
public mypanel(id, model) {
add(new dropdownchoice("id", _model_, ...
do
add(new dropdownchoice("id", (IModel)Objects.clone(model), ...
