futile attempt to fix things):
@Override
protected void onModelChanged() {
super.onModelChanged();
if (getModelObject()!= null) {
control.setModel(getModel());
}
The problem is that the control.setModel() expects a Model of a Collection,
while getModel() returns a Model of a SortedSet:
The method setModel(IModelCollection MantechControl ) in the type
FormComponentCollection MantechControl is not applicable for the
arguments (IModelSortedSet MantechControl ). I have good business reasons
to use a sorted set, and what I think are good reasons to use a
FormComponentPanel and a ListMultipleChoice. But should I do something
different?
Meanwhile, I've created a wicket/metagen quickstart project and am running
into a similar problem there. I can upload the project somewhere if you
want more info. Here I wrote a class ColorfulPerson that has a String name
and a SortedSetColor colors. In trying to write a FormComponentPanel for
this, I have an obvious error at the indicated line:
public class ColorfulPersonPanel extends FormComponentPanelColorfulPerson {
private static final long serialVersionUID = -457616015428125432L;
private final FormComponentString name;
private final FormComponentCollectionColor colors;
private ListColor colorChoices = Arrays.asList(Color.values());
public ColorfulPersonPanel(String id, IModelColorfulPerson model) {
super(id, model);
name = new TextFieldString(name, new ModelString());
add(name);
colors = new ListMultipleChoiceColor(colors, new
SetModelColor(), colorChoices);
add(colors);
onModelChanged();
}
@Override
protected void onModelChanged() {
super.onModelChanged();
ColorfulPerson colorfulPerson = getModelObject();
if (colorfulPerson != null) {
name.setModel(MetaModel.of(colorfulPerson).get(ColorfulPersonMeta.name));
colors.setModel(MetaModel.of(colorfulPerson).get(ColorfulPersonMeta.colors));
// Error as the model is one of
SortedSetColor while the ListMultipleChioice expects a model of
CollectionColor.
} else {
name.setModelObject(null);
colors.setModelObject(null);
}
}
Could there be a MetaModel.as(Class? castingClass) method?

Qeustions about SortedSet and ListMultipleChoice (with and without Metagen)
In my project, for business reasons, we have classes with SortedSet members.
The classes and their elements are all Serializable. I'm having trouble
working with a SortedSetMantechControl object; when I try creating a
ListMultipleChoiceMantechControl object for it (and putting it into a

banner));
add(control);
onModelChanged();
}
The onModelChanged() method has (after I extracted some local objects in a
futile attempt to fix things):

The problem is that the control.setModel() expects a Model of a Collection,
