Was not such a good idea after all I just found out as - of course -
that is used as the next input.

Can't we make that the default? You know how to do that?
This is one alternative:
public class NullValueModelDecorator<T> implements IWrapModel<T>
{
private static final long serialVersionUID = 1L;
private final IModel<T> model;
private final T replacementForNull;
public NullValueModelDecorator(IModel<T> model, T replacementForNull)
{
this.model = model;
this.replacementForNull = replacementForNull;
}
public void detach()
{
}
public IModel getNestedModel()
{
return null;
}
public T getObject()
{
T value = model.getObject();
return (value != null) ? value : replacementForNull;
}
public void setObject(T object)
{
if (object != null && (!replacementForNull.equals(object)))
{
model.setObject(object);
}
}
}
but the css way sounds more elegant
