Re: [Wicket-develop] should we make AbstractResource serializeable or not?

[Johan Compagner]

The best thing to do is to store hibernate ID (the pk) of the object within youre listitem components. And then if the request comes back you popuplate youre object again with that pk. Hibernate objects are also serializeable (the most time) so you could choose for to serialize it.. But keeping hibernate objects over multiple request should be done (you will get transient object exceptions then) johan Cameron Braid wrote: Ok.. I must have done something wrong, because I had a list of objects (that weren’t serializable) in a detachable pageable list model, and I was receiving an exception saying that it wasn’t serializable.   How does the case work where I bind the elements in the list to more components.  I presume that I would have to wrap each of them in a detachable model too ?  This is probably where I have gone wrong.   For example..   Say I have a list of ContactEntity objects (hibernate mapped pojos) I have a detablable pageable list model of contacts (using a hibernate query and storing the criteria as a non transient property of the list model) Then to make a grid editor, I bind properties of each contact to TextField inputs.   Would I need to make a detachable contact model that loads the contact by id and bind it to the form components ?   Thanks,   Cameron.   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Johan Compagner Sent: Wednesday, 9 March 2005 12:49 AM To: wicket-develop@lists.sourceforge.net Subject: Re: [Wicket-develop] should we make AbstractResource serializeable or not?   because the model itself will still be serialized. A detachable model doesn't mean the model itself is detached but the developer can detach the contents. For example if you have a heavy weight component in your model that you can relookup from somewhere by an ID. Then in the detach you store that id in a non transient instance reference. And youre heavy weight object is cleared or hold only in a transient reference. Then when the component and its model are serialized only the id is serialized with the model not youre complete object. johan Cameron Braid wrote: Speaking about serializable stuff...   With detachable models, why do they also have to be serializable ?   Cameron.     -----Original Message----- From: [EMAIL PROTECTED] [mailto:wicket-develop- [EMAIL PROTECTED]] On Behalf Of Johan Compagner Sent: Wednesday, 9 March 2005 12:28 AM To: Wicket Developer List Subject: [Wicket-develop] should we make AbstractResource serializeable or not?   Our clone by serialize did encounter a few serialization exceptions for example all the Resources (like image). Should we make AbstractResource serializeable? those can be in the session..   johan         ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
