[jira] [Comment Edited] (SLING-5975) POST fails with modern
multi-value parameter names containing brackets
[ https://issues.apache.org/jira/browse/SLING-5975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15426545#comment-15426545 ]

---------------------------------------------------------------
[~kwin] This is useful especially when using jQuery to modify content which i assume might be a relatively common use-case. jQuery >= 1.3 is submitting multi-value fields in this form by default. As of now it's possible to switch back to the old behaviour by adding a request option {{traditional: true}} (see
http://api.jquery.com/jquery.param/) but this needs to be set explicitly which is not obvious.
I found a more detailed reasoning about this change at http://benalman.com/news/2009/12/jquery-14-param-demystified.
As there is a workaround the type might be changed to Improvement or Wish.
