[jira] Commented: (WW-2122) select tag listKey/listValue defaults apply to Maps only

["Laszlo Borsos (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/struts/browse/WW-2122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_41949 ] 

Laszlo Borsos commented on WW-2122:
-----------------------------------

The restriction is done in org.apache.struts2.components.ListUIBean, which is an abstract base class of 5 bundled components. So serious consideration is needed not to break existing code. Otherwise the modification would be this:

In 2.0.9: Line 106 and 119: "if (value instanceof Map)" to be omitted.

PS. Did not find how to provide patches.

> Webwork book states for select tag attributes:
> listKey - String - Expression for the list key; key by default.
> listValue - String - Expression for the list value; value by default.
> I had a list of type ArrayList<KeyValueBean> and to my surprise it did not work with the defaults. I had to write.
> <s:select name="id" list="nonmember" listKey="key" listValue="value" />
> I think it need not be restricted to Maps.
