Re: Models and page serialization
Do your business objects have common property ? base class/interface, annotation, ... ? If YES then you can check for it and write the nice error message when you see such.

Re: Models and page serialization
The problem is that my business objects do implement serializable for another reason. However, I don't want Wicket to serialize them. So I could remove Serializable and see what happens but I was hoping for a way to just look at what is getting serialized. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Models-and-page-serialization-tp4663668p4663758.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Models and page serialization
See for example SerializableChecker. It does the same - checks that a serialized object implements java.io.Serializable. If it doesn't then it prints a nice message explaining where this object is used.

Re: Models and page serialization
Thanks for the tip. I'm a little unclear on what this is telling me though. Wouldn't this just tell me if the detach method of all my LDMs was called? What I'm interested in determining is where my LDMs are directly referencing objects that will inadvertantly get serialized with the LDM. For example, if an LDM has a member variable pointing to an object or the LDM accesses a final variable from its parent class. I want to be sure I'm not serializing business objects or references to business objects along with the page. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Models-and-page-serialization-tp4663668p4663746.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Models and page serialization
Hi, If you use Wicket 6.x then you can use special impl of org.apache.wicket.core.util.objects.checker.IObjectChecker To use it you have to extend org.apache.wicket.serialize.java.JavaSerializer#newObjectOutputStream. See for example how org.apache.wicket.serialize.java.JavaSerializer.SerializationCheckerObjectOutputStream#writeObjectOverride uses SerializableChecker.

Models and page serialization
I would like to be able to analyze a particular Wicket page to determine where I might be using models incorrectly. The model behind the page is a very nested serializable object that is kept in a document cache. The idea is to use a loadable detachable model that will retrieve the object from the cache on load. However, I'm fairly certain that there are places where objects from within the object hierarchy are being used incorrectly. I'm assuming that this probably results in portions of the object getting serialized with the page. Are there any tools or logging that would let me see the serialized page in a readable format? I guess one way I could analyze the problem is to make my object unserializable and work through the errors.
