Well I got an Overridden PropertyModel to give me the behavior I want, but it
seems kind of dangerous. Hoping there's a better way to accomplish this.
public class NegativePropertyModel extends PropertyModel {
public NegativePropertyModel(final Object modelObject, final String
expression) {
super(modelObject, expression);
}
@Override
public Object getObject() {
if(super.getObject() != null) {
return !((Boolean)super.getObject()).booleanValue();
}
return null;
}
@Override
public void setObject(Object o) {
if(o instanceof Boolean) {
super.setObject(o);
}
}
}
