Of course these are only details, but I wanted to get clear.
It seems that in this case I cannot use List interface although List
interface has super-interface Collection.
When List is replaced with Collection all is OK, no compiler warnings:
IModel<Collection<String>> allYearsModel = new
PropertyModel<Collection<String>>(this, "allYears");
ListMultipleChoice<String> allYears = new
ListMultipleChoice<String>("allYears", allYearsModel, new
ArrayList<String>());
I haven't checked the source yet, but probably someone could comment on this
- why so?
