isVisible() with surrounding Markup and LoadableDetachableModel

[Warren]

I have a form that has a lot of labels with surrounding markup that needs to
be visible based on whether their is a value or empty string. The form uses
a CompoundPropertyModel based on a LoadableDetachableModel. How do I check
the model value of a Label in isVisible() without having load() of
LoadableDetachableModel being called twice.


<wicket:enclosure child="lineItem.item.department.departmentName">
        <br>Dept: <span
wicket:id="lineItem.item.department.departmentName">Supplements</span>
</wicket:enclosure>


Label departmentName = new Label("lineItem.item.department.departmentName")
{
        public boolean isVisible()
        {
                // How do I check value without load() being called again
        }
};


Thanks,

Warren Bell
