Hi Phil,
Just got a working example. Things for you to try out:
* the @ValidateNestedProperties({...}) belongs on the private
List<Person> people field, the getter method, or the setter method,
not on the event handler;
* make sure that you have a public no-args constructor, public
Person() {}, in the Person class;
* if nothing solves the problem, compare with my code below.
-- HomeActionBean.java --
public class HomeActionBean extends BaseActionBean {
private List<Person> people;
public List<Person> getPeople() {
return people;
}
public void setPeople(List<Person> people) {
this.people = people;
}
@DefaultHandler
public Resolution index() {
people = new ArrayList<Person>();
people.add(new Person("name1", "email1"));
people.add(new Person("name2", "email2"));
return new ForwardResolution("/index.jsp");
}
public Resolution update() {
System.out.println("people: " + people);
return new ForwardResolution("/index.jsp");
}
}
-- index.jsp --
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %>
<%@ taglib prefix="stripes" uri="http://stripes.sourceforge.net/stripes.tld"; %>
<table>
<stripes:form beanclass="example.action.HomeActionBean" method="POST">
<c:forEach items="${actionBean.people}" var="person" varStatus="loop">
<tr>
<td><stripes:text name="people[${loop.index}].name"
value="${person.name}"/></td>
<td><stripes:text name="people[${loop.index}].email"
value="${person.email}"/></td>
</tr>
<c:set var="newIndex" value="${loop.index + 1}" scope="page"/>
</c:forEach>
<tr>
<td><stripes:submit name="update" value="update"/></td>
</tr>
</stripes:form>
</table>
-- Person.java --
public class Person {
public Person() { }
public Person(String name, String email) { setName(name); setEmail(email); }
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
private String email;
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String toString() {
return name + " " + email;
}
}
Let me know what you find.
Cheers,
Freddy

- Sure thing Freddy, actionBean:
-
- private List<Person> people;
-
- //called in default 'view' handler method so intial form is
- populate with people data that can be updated
- public void prepareView(){
- people = new ArrayList<Person>();
- people.add(new Person("tom","t...@..."));
- people.add(new Person("harry","ha...@..."));
- people.add(new Person("adrian","adr...@..."));
- people.add(new Person("julie","ju...@..."));
- people.add(new Person("sue","s...@..."));
- }
-
- private List<Person> people;
-
- @ValidateNestedProperties ({
- @Validate(field="name", required=true, minlength=3,
- maxlength=15, on="update"),
- @Validate(field="email", required=true
- ,mask="[\\w\\...@[\\w\\.]+\\.\\w+", on="update")
- })
- @HandlesEvent("update")
- public Resolution updatePeople(){
- logger.info("people updated :" + people);
- return new RedirectResolution(WelcomeActionBean.class,"view");
- }
-
- public List<Person> getPeople() {
- return people;
- }
-
- public void setPeople(List<Person> people) {
- this.people = people;
- }
-
- JSP:
-
- <stripes:form
beanclass="com.orangehome.ui.action.admintools.ExampleActionBean"
- method="POST">
- <c:forEach items="${actionBean.people}" var="person"
varStatus="loop"-
- <tr>
- <td><stripes:text name="people[${loop.index}].name"
- value="${person.name}"/></td>
- <td><stripes:text name="people[${loop.index}].email"
- value="${person.email}"/></td>
- </tr>
- <c:set var="newIndex" value="${loop.index + 1}"
scope="page"/-
- </c:forEach>
- <stripes:submit name="update" value="update"/>
- </stripes:form>
-
- Stripes is falling over in PropertyExpressionEvaluation.java:652,
- looks like it's trying to instantiate a primitive (the index) :
-
- Class clazz = convertToClass(node.getValueType(), node);
-
- if (clazz.isArray()) {
- return Array.newInstance(clazz.getComponentType(), 0);
- }
- else if (clazz.isEnum()) {
- return clazz.getEnumConstants()[0];
- }
- else if (clazz.isInterface() ) {
- return ReflectUtil.getInterfaceInstance(clazz);
- }
- else {
- return clazz.newInstance();
- }
-
- Cheers,
- Phil
