Igor Vaynberg resolved WICKET-3203.
-----------------------------------

    Resolution: Won't Fix
      Assignee: Igor Vaynberg

its a one liner to convert an array to a List, i dont see why we need to add another 20 constructors all over the place to accept arrays. i think the in-memory overhead is trivial, and when serialized they take the same amount of space because jdk lists override serialization and optimize it.

> Looking at the Choice classes under org/apache/wicket/markup/html/form
> it occurred to me that there could be parallel versions that
> are Array-base mirroring the current ArrayList-based classes.
> List based Choice classes:
>  AbstractChoice.scala               
>  AbstractSingleSelectChoice.scala   
>  CheckBoxMultipleChoice.scala       
>  DropDownChoice.scala
>  ListChoice.scala
>  ListMultipleChoice.scala
>  RadioChoice.scala
> Array based Choice classes:
>  AbstractArrayChoice.scala
>  AbstractSingleSelectArrayChoice.scala
>  CheckBoxMultipleArrayChoice.scala
>  DropDownArrayChoice.scala
>  ListArrayChoice.scala
>  ListMultipleArrayChoice.scala
>  RadioArrayChoice.scala
> For those times when one needs to dynamically change the size
> of the data-container, Lists are easier than Arrays, but most
> of the time the number of elements in a DropDown is
> constant for the life of the application and an Array
> takes less memory than a List and access is faster (granted,
> neither of these is by very much).
> There would also have to be an ArrayModel class and a
> toArray method in the Model class.
