>             Project: Struts 2
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 2.5.12
>            Reporter: Mitth'raw'nuruodo

>             Fix For: 2.5.13

> The {{com.opensymphony.xwork2.conversion.impl.StringConverter}} class, since Struts 2.5.11, incorrectly handles arrays containing null; it converts them to arrays containing the string "null" (using {{String.valueOf}}).
> This is breaking one of our applications; some pages are OK, but on other pages, every non-provided field is populated with the String "null".
> This is a similar issue to WW-4737, but occurring in different code.
> Please ensure that conversion to String always uses the two-argument version of {{Objects.toString}}, which preserves nulls, rather than {{String.valueOf}}, which converts them to the four-letter string "null".
