>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket-extensions
>    Affects Versions: 1.5.3
>            Reporter: Stefan Schulte
>            Assignee: Pedro Santos
>            Priority: Minor
>             Fix For: 1.5.4, 6.0.0

> AjaxEditableLabel<Integer> label = new AjaxEditableLabel<Integer>("label", new PropertyModel<Integer>(this, "value"));
> form.add(label);
> label.setRequired(true);
> label.add(new RangeValidator<Integer>(1, 10));
> Using a RangeValidator<Integer> on an AjaxEditableLabel<Integer>  causes an ClassCastException after editing the label. 
> java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String
> This can be avoided by setting the type explicit on the AjaxEditableLabel.
> label.setType(Integer.class);
> But this wasn't necessary in Wicket 1.4.19. In this version all works fine without setting the type explicit.
> I found out, that AbstractTextComponent.resolveType() is not able to get the type of the DefaultModel of the AjaxEditableLabel in Wicket 1.5.3.
> I will attach two QuickStarts to demonstrate the bug. One with wicket 1.4.19 and the other with Wicket 1.5.3
