Hi,
I would like to know what is the best way to work with the method
iterator of DataProvider.
I have created a class implementing IDataProvider. Depending of a
parameter, the DAO service called is not the same inside in the
iterator method. For some DAO services, a list is returned but for one
I see several undefined objects:
result
requestFormModel
it
If these are defined at the class level, they must be serializable.
If you have Logging set at Info, Wicket will give you the actual field that
is not serializable, although from the error it looks like something to do
with
Further, you don't really need to define the Iterator, just return them.
public Iterator iterator(int first, int count) {
result = new ArrayListPlatformDTO();
if (requestFormModel != null) {
if (requestFormModel.getId() != null) {
Iterator is not serializable,
wicket will try to serialize it if it's at class level
so either move it inside iterator method
or make it transient ,
In your case,you can easily move it inside method ;)

List Result = new ArrayListPlatformDTO(); must be defined outside of the
iterator method
and also the answer to my question.
When the result is empty or null, then I must return a null iterator
