[jira] Created: (WW-2612) Support for Lists using s:hidden tag
Support for Lists using s:hidden tag
------------------------------------
Key: WW-2612
URL: https://issues.apache.org/struts/browse/WW-2612
Project: Struts 2
Issue Type: Improvement
Affects Versions: 2.0.11.1
Reporter: Steve Akins
Priority: Minor
If you have a List in an Action that you want to maintain through a form I would expect that coding a s:hidden tag for the List would work.
Currently the s:hidden tag does represent the List in the generated HTML however when the form is submitted the parameter is not translated back into the List correctly.
eg.
If you have a List called "ids" which contains 4 Strings "22030", "6496",
"6457", "6448" and
When the following tag is used:
<s:hidden name="resend.ids" />
It produces the following HTML:
<input type="hidden" name="resend.ids" value="[22030, 6496, 6457, 6448]" id="/test/resend_resend_ids"/>
When the form is submitted the "ids" List is populated with one String
"[22030, 6496, 6457, 6448]" instead of 4 Strings "22030", "6496", "6457", "6448".
This looks like XWorkBasicConverter needs some enhancing but I haven't figured out how.
The only workarounds for this that I can see are:
1. Iterate through the List in the JSP and use a s:hidden for each element in the List. This will generate a lot of unnecessary HTML.
2. Create a custom converter but I think that support for Lists should be out of the box.

[jira] Commented: (WW-2612) Support for Lists using s:hidden tag
Posted by "Jeromy Evans (JIRA)" <ji...@apache.org>.

Jeromy Evans commented on WW-2612:
----------------------------------
I agree it's confusing for Struts users that if you get an array or list contains:
["22030", "6496", "6457", "6448"] (4 elements)
as a string you receive:
"[22030, 6496, 6457, 6448]"
but if you set that sting value on the same array or list your receive
["[22030, 6496, 6457, 6448]" ] (one element)
I understand the issue is that OGNL syntax for a list is:
"{'22030', '6496', '6457', '6448'}"
and for a native array:
"new String[] {'22030', '6496', '6457', '6448'}"
The default converter should either support OGNL's list syntax {values} or convert [ values] to an array/list when the target property is such.
