in struts2-REST environment,i cannot run struts2/showcase/person example.
in struts2/showcase/person,there is a <s:iterator>:
<s:form action="person/person" theme="simple" method="post" validate="false">
<table>
<tr>
<th>ID</th>
<th>First Name</th>
<th>Last Name</th>
</tr>
<s:iterator var="p" value="persons">
<tr>
<td>
<s:property value="%{id}"/>
</td>
<td>
<s:textfield label="First Name"
name="persons(%{id}).name"
value="%{name}" theme="simple"/>
</td>
<td>
<s:textfield label="Last Name"
name="persons(%{id}).lastName"
value="%{lastName}" theme="simple"/>
</td>
</tr>
</s:iterator>
</table>
<s:submit method="update" value="Save all persons"/>
</s:form>
the action.update:
public HttpHeaders update() {
System.out.println("=======update");
for (Person p : persons) {
personManager.getPeople().remove(p);
personManager.getPeople().add(p);
}
return new DefaultHttpHeaders("index");
}
when i submit the form,there is lots of exceptions for each input field:
ognl.OgnlException: Error getting property descriptor: null
just before ("=======update");
seems to have no value transfer to action variable: List person.
how to manage this?
thanks
