When creating a Web application.
Can I fetch a dataObject to view it on a view page.
Then modify the contents of this dataObject (without comminging) over
serveral requests cycles and then finally commit the changes.
In other words, can I store the dataObject in the session so I don't
have to fetch again for every trip to the server during some updates, or
do I have to fetch it every time a request is processed? How long can a
dataObject stay active before I can no longer commit it? Do I need some
buffer object like a VO object or JavaBean?
Are there any guidelines for a good design?
Thanks
