Can anyone point me to a working example of Struts2 indexed properties? I've
managed to get list indexing working:
<s:checkbox name="users[%{#status.index}].administrator"... />
but haven't had any luck with the map style:
<s:checkbox name="filter[%{#state.name}]"... />
(where state.getName returns a String), or the property-indexing style:
<s:textfield name="beanList(%{#bean.id}).name" value="%{#bean.name}"/>
(as described in the http://cwiki.apache.org/WW/type-conversion.html wiki
). I tried running something similar to the wiki example (see attached
code), but when I submit my form I see an exception thrown for every attempt
to set a property (see below). Any insight or pointers would be greatly
appreciated.
The top of the exception stack:
ERROR 17:31:23,510 [com.opensymphony.xwork2.util.XWorkMethodAccessor] - An

... etc, etc
The relevant piece of my struts.xml file:
<action name="MyBean_show" method="show" class="MyBeanAction">
<result>/jsp/MyBean.jsp</result>
</action>
<action name="MyBean" class="MyBeanAction">
<result type="chain">MyBean_show</result>
</action>
Here's the bean (as per wiki):
http://www.nabble.com/file/p11837653/MyBean.java MyBean.java
Here's the action code:
http://www.nabble.com/file/p11837653/MyBeanAction.java MyBeanAction.java
And the conversion properties:
