I am using wicket 1.3.5 and db4o 7.4.63.11890. My objects are being passed between pages using a subclass of LoadableDetachableModel (see below)
My problem is: 1. I edit an object on PageA 2. I use the back button and then re-submit the form I edited and now I have two objects in the database. Any ideas on why this is happening? Cheers, Pieter package com.musmato.wicket.model; import org.apache.wicket.model.LoadableDetachableModel; import com.musmato.dao.BaseFactory; public abstract class BaseWebModel<T> extends LoadableDetachableModel { private static final long serialVersionUID = 1L; protected Long id; public abstract Class<T> getBaseClass(); public abstract BaseFactory<T> getFactory(); public BaseWebModel(Long id) { this.id = id; } public BaseWebModel(T object) { this.id = getFactory().getID(object); } @Override protected Object load() { if (id == null) { return getFactory().getNewObject(); } return getFactory().getById(id); } }
