Are we talking about a "wizard" here? What if you used something like this:
https://wicketopia.svn.sourceforge.net/svnroot/wicketopia/trunk/wicketopia/src/main/java/org/wicketopia/model/proxy/ProxyModelManager.java Basically, the "models" cache their values until you call "commit" on the ProxyModelManager. So, you can do as many steps in the wizard as you want and if you base your components on proxied models (that wrap PropertyModels around a LoadableDetachableModel), then your object will only be loaded from the database at the end (during the "commit" of the proxy models) and you won't lose your "edits."
