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".
