Thank you again. But I'm not very sure of what you are talking about... I declared the DropDowns that way so they are able to change the content for every language with every localization change. But as part of a Form with assigned CompoundPropertyModel, I supposed it should be easy to just map the selected value in the property with the same name.
The strange is that I have exactly the same code for a different Dropdown, and I can retrieve the value correctly: Page class: membershipLevels = new DropDownChoice ("membershipLevel", new LoadableDetachableModel() {protected Object load() {return getMembershipLevels();}}, new ChoiceRenderer ("membershipLevelName", "membershipLevelID")); Compound Property: private MembershipLevel membershipLevel; Submit: System.out.println ("MEMBERSHIPLEVEL:" + userInformation.getMembershipLevel().getMembershipLevelID()); So yes, you are right, I think I don't understand how it works...
