Description

When I use NumberTextField to edit values in the list of integers form submission fails with
Last cause: null
WicketMessage: Exception 'java.lang.NullPointerException' occurred during validation org.apache.wicket.validation.validator.RangeValidator

TextField works fine for list of Strings, so form 1 does not work, form2 works fine. Expectation is that form 1 works, repro case attached

ArrayList ints = new ArrayList(Arrays.asList(1,2,3,4));
ArrayList strings = new ArrayList(Arrays.asList("1","2","3","4"));

public ArrayList getInts()

{ return ints; }

public void setInts(ArrayList ints)

{ this.ints = ints; }

public ArrayList getStrings()

{ return strings; }

public void setStrings(ArrayList strings)

{ this.strings = strings; }

Form f = new Form("editor", new CompoundPropertyModel(this));
ListView ints = new ListView("ints") {

@Override
protected void populateItem(ListItem listItem)

{ listItem.add( new NumberTextField<Integer>("v", (IModel<Integer>) listItem.getDefaultModel(),Integer.class)); }

};
f.add(ints);
add(f);

Form f2 = new Form("editor2", new CompoundPropertyModel(this));
ListView strs = new ListView("strings") {

@Override
protected void populateItem(ListItem listItem)

{ listItem.add( new TextField("v", listItem.getDefaultModel())); }

};
f2.add(strs);
add(f2);
