CompoundPropertyModel is just meant as a convenience. There's nothing
wrong with using it for your other fields and giving an explicit model
to your CheckBoxMultipleChoice...

    form = new Form("form" new CompoundPropertyModel(domainModel));
    add(form);
    form.add(new TextBox("textProperty")); // uses compound model
    form.add(new CheckBoxMultipleChoice("intProperty",
        new BitMapModel(new PropertyModel(domainModel, "intProperty")),
        new BitMapModel(new Model(-1)), // all bits set
        new ChoiceRenderer() { ... }));
