Sven Meier resolved WICKET-6534.
--------------------------------
Resolution: Invalid
Assignee: Sven Meier
Your RequiredTextField does not know the type of your model object, so String
is used as fallback.
Either you use a model that provides this type information (e.g.
PropertyModel), or you'll have to pass the type to the constructor explicitly:
{code:java}
new RequiredTextField<>("ho",new Model<Integer>(month), Integer.class);{code}
> RangeValidator throws java.lang.Integer cannot be cast to java.lang.String
> exception
