I give a sample is use when I need to populate an view :
I got an ActionForm :
public class StudentForm extends ActionForm {
private String formationSelected = "Analyste Programmeur";
private Collection formationList = null;
private Collection formationListID = null;
private Collection groupList = null;
private Collection groupListID = null;
private String group = "cycle 1a";
......
......
/**
* Get the formationList.
* @return Collection.
*/
public Collection getFormationList () {
formationList = Formation.getFormations();
return formationList;
}
/**
* Get the formationListID.
* @return Collection.
*/
public Collection getFormationListID () {
formationListID = Formation.getFormationsID();
return formationListID;
}
/**
* Get the groupList.
* @return Collection.
*/
public Collection getGroupList () {
groupList = Groupe.getGroupsOfStudent();
return groupList;
}
/**
* Get the groupList.
* @return Collection.
*/
public Collection getGroupListID () {
groupListID = Groupe.getGroupID();
return groupListID;
}
..
I got an viewstudent action :
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
Collection students = null;
StudentForm studentForm = (StudentForm) form;
students = getStudents ();
HttpSession session = request.getSession();
session.setAttribute("students", students);
return mapping.findForward("viewstudent");
}
/**
* Get all students.
*/
protected ArrayList getStudents () {
return Student.getStudents();
}
And my jsp view for studentview is :
<%@ page session="true" %>
<%@ page import="org.apache.taglibs.display.test.TestList,
org.apache.taglibs.display.test.ListHolder,
java.util.List"%>
<%@ taglib uri="http://jakarta.apache.org/taglibs/display"; prefix="display"
%>
<%@ taglib uri="/WEB-INF/struts-menu.tld" prefix="menu"%>
<html>
<head>
</head>
<body>
<script language="JavaScript1.2" src="./scripts/coolmenus3.js">
</script>
<script src="./scripts/coolmenu-config.js">
</script>
<menu:useMenuDisplayer name="CoolMenu"
bundle="org.apache.struts.action.MESSAGE">

</menu:useMenuDisplayer>
<p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<display:table width="85%"align="left"
name="students"
scope="session"
pagesize="5"
requestURI="/ibmss/form/viewstudent.jsp"
export="true"
decorator="org.apache.taglibs.display.test.Wrapper">

<display:column property="insuranceNumber" title="No assure"/>
<display:column property="formationSelected" title="Formation"/>
<display:column property="group" title="Groupe"/>
</display:table>
</body>
</html>

the student an user who whant to edit him
I got an getstudentaction who create a new
studentform and populate this form with
the data of the choosen student previously
selected.

Subject: editable list using nested:iterate and lazyList
I posted this already on another thread, but I thought that I would try it
again with some more detail.
I am trying to create an editable list based on some examples using
nested:iterate and ListUtils.lazyList that I have seen offered on this
mailing list.
I have created a simple example, the flow of which is detail action ->
jsp -> control action. The form that is used by all of these looks like:
private List bananas = ListUtils.lazyList(new ArrayList(),
new Factory()
{
public Object create() {
return new BananaBean();
}
});
public List getBananas() { return bananas; }
The detail action adds BananaBean instances using bananas.add. Inside a
nested:form on the jsp I have
<nested:iterate property="bananas">
<nested:text property="flavour"/>
</nested:iterate>
and in the control action, I do form.getBananas() and print out the values
to see if they reflect the changes I made on the page.
I can't even successfully display the jsp. I get the following exception:
java.lang.IllegalArgumentException: Property 'bananas' is not indexed
I can't think of a simplier example. Any ideas?
I'm using nested_tags_10.jar with 1.3.1
BTW: LazyList implements Collection so it's indexed, right?
