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","[email protected]"));
people.add(new Person("harry","[email protected]"));
people.add(new Person("adrian","[email protected]"));
people.add(new Person("julie","[email protected]"));
people.add(new Person("sue","[email protected]"));
}
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
