Re: LoadableDetachableModel/Serialization Problem
you have to chain your models, so instead of
item.add(new Label(title, publication.getTitle()));
do
item.add(new Label(title, new PropertyModel(item.getModel(), title));
instead of
IModel authorsModel = new LoadableDetachableModel() {
@Override
protected Object load() {
return publication.getAuthorsInOrder();
}
};
do
authorsModel=new PropertyModel(item.getModel(), authorsInOrder);
that way you never have to hold a reference to the domain object
itself, only a model to it.

Re: LoadableDetachableModel/Serialization Problem
I actually tried that, however my publication object looks like this. (I
trimmed it to the relevant parts). as you can see there's no authorsInOrder
Property only the authors property which can't be displayed to the user. I
have to call getAuthorsInOrder() to retrieve the the list of author objects.
Right now i can't change this pojo implementation but i can try to convince
the domain model guy. What are my options if it can be changed and if it
can't?

the propertymodel will call the getter function.

Re: LoadableDetachableModel/Serialization Problem
Thanks igor. i just tried it and it worked. It's so cool property models work
like that.
