[jira] [Created] (WW-4831) Array-of-null parameters are converted to arrays containing "null"

Mitth'raw'nuruodo created WW-4831:
-------------------------------------

             Summary: Array-of-null parameters are converted to arrays containing "null"
                 Key: WW-4831
                 URL: https://issues.apache.org/jira/browse/WW-4831
             Project: Struts 2
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.5.5, 2.5.8
            Reporter: Mitth'raw'nuruodo
             Fix For: 2.5.12


The {{org.apache.struts2.dispatcher.Parameter.Request}} class (added in Struts 2.5.3) 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 "null".
