[jira] Commented: (IBATIS-60) PaginatedDataList not Serializable
[ http://issues.apache.org/jira/browse/IBATIS-60?page=comments#action_57864 ]
Ate Douma commented on IBATIS-60:
---------------------------------
I know I can do that. But the point is, I don't want to.
There *is* a functional value in (de)serialization of session state by a web container!
Anyway, I think I probably won't be the only one experiencing this problem.
A lot of J2EE applications make proper use of the (session) state serialization and providing
Serializable objects for use in J2EE application is common practice in my opinion.
I didn't look at the code of the PaginatedDataList, but for what specific reason would you not
want it to be Serializable?
And if some (or all) contained data should never be serialized you could implement the readObject
and writeObject to handle it yourself (I know that might be a lot of, or too much, work though).
Regards, Ate
