In Model<T>, the type T should not extend Serializable.
-------------------------------------------------------
Key: WICKET-4041
URL: https://issues.apache.org/jira/browse/WICKET-4041
Project: Wicket
Issue Type: Improvement
Components: wicket
Affects Versions: 1.5-RC7
Reporter: Craig P. Motlin
The problem is that lots of common interfaces (like List) don't implement
Serializable even though most/all of their subclasses are in fact serializable.
That means clients wind up with code containing potentially unsafe casts like
this.
Model<ArrayList<MyDomainObject>> listModel = new
Model<ArrayList<MyDomainObject>>()
{
@Override
public ArrayList<MyDomainObject> getObject()
{
return (ArrayList<MyDomainObject>)
DominionApplication.get().getMyDomainObjects();
}
};
It still makes sense for Model to check that the type is an instanceof
Serializable at runtime, but it's too much to enforce at compile time.
