Okay, I changed it back to settings[0] type syntax (I had tried it before and
it didn't work), so now I have this:
<s:iterator value="%{settings}" status="rowstatus">
<tr>
<th>
<input
name="settings[<s:property value="#rowstatus.index"
/>].title" value="<s:property value="title" />" type="hidden" />
<label
for="setting_<s:property value="id" />">
<s:property value="title" />:
</label>
</th>
<td>
<input
id="setting_<s:property value="id" />"
name="settings[<s:property value="#rowstatus.index" />].value"
value="<s:property value="value" />" />
</td>
</tr>
</s:iterator>
And now I am getting this in the logs (repeated for each attribute id,
title, value):
ERROR com.opensymphony.xwork2.util.InstantiatingNullHandler - Could not
create and/or set value back on to object
ognl.OgnlException: settings [java.lang.IllegalArgumentException: argument
type mismatch]
ERROR com.opensymphony.xwork2.interceptor.ParametersInterceptor -
ParametersInterceptor - [setParameters]: Unexpected Exception caught setting
'settings[0].title' on 'class com.rjssoft.webdocs.admin.SettingAction: Error
setting expression 'settings[0].title' with value
'[Ljava.lang.String;@185fe0c'
So again, it's failing trying to set a String[] to a String value on the
Setting object which has all of the getters/setters and are defined to
handle String values.
Any insight?
