Subject [jira] [Commented] (WW-4737) Array-of-null parameters are converted to arrays containing "null"
Date Tue, 31 Jan 2017 22:50:51 GMT

    [ https://issues.apache.org/jira/browse/WW-4737?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15847681#comment-15847681

Mitth'raw'nuruodo commented on WW-4737:
---------------------------------------

I could, but I'm not sure how many files I'd need to post before it would make sense, and
since we're unable to update to the latest (thus most secure) version of Struts, I'm not sure
it's wise for us to be publicly sharing source code.

I'll aim to post redacted versions.

Can {{Parameter.Request}} simply be adjusted to handle arrays of nulls properly?

> 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".
