RE: logic:iterate inside a logic:iterate ??

[Robert Taylor]

logic:iterate id=document name=formName property=documents
logic:iterate id=lv name=document property=labelValueBeans
bean:write name=lv property=label/
bean:write name=lv property=value/
/logic:iterate
/logic:iterate

You should probably use JSTL for this.

c:forEach var=document items=${formName.documents}
c:forEach var=lv items=${document.lableValueBeans}
c:out value=${lv.label}/
c:out value=${lv.value}/
/c:forEach
/c:forEach

 Subject: logic:iterate inside a logic:iterate ??
 
 
   
Hi
 
   I'am a Struts newbie, sorry if it is a classic question.
 
   My question is about logic:iterate
 
   I have a vector of documents.
   In my application a document is a vector of LabelValueBean. I wish to 
 write both the label and the value.
 
   I wish to write all my documents so I iterate through my vector 
 of documents.
 But after that how can I iterate through my vector of LabelValueBean ???
 
 Basically here's what I want to do :
 
 for_each_document
 {
  for_each_LabelValueBean_in_the_current_document
  {
   write LabelValueBean.Label;
   write LabelValueBean.Value;
  }
 }
 
 thanks for you help

[Jan Vervecken]

try something similar to this

(of course all the Java code to construct the lists should be in (or called by) a 
Struts Action class, so focus on the use of the logic:iterate tag)

--8loop.jsp--
%@ page import=java.util.* %
%@ taglib uri=/WEB-INF/struts-bean.tld prefix=bean %
%@ taglib uri=/WEB-INF/struts-html.tld prefix=html %
%@ taglib uri=/WEB-INF/struts-logic.tld prefix=logic %
%!
public class Person
{
String fName = null;
LinkedList fEmailList = new LinkedList();
public String getName() { return fName; }
public LinkedList getEmailList() { return fEmailList; }
}
%
%
LinkedList vPersonList = new LinkedList();
Person vPerson = new Person();
vPerson.fName = Jan Vervecken;
vPerson.fEmailList.add([EMAIL PROTECTED]);
vPerson.fEmailList.add([EMAIL PROTECTED]);
vPersonList.add(vPerson);
vPerson = new Person();
vPerson.fName = Genty Jean-Paul;
vPerson.fEmailList.add([EMAIL PROTECTED]);
vPerson.fEmailList.add([EMAIL PROTECTED]);
vPerson.fEmailList.add([EMAIL PROTECTED]);
vPersonList.add(vPerson);
request.setAttribute(personList, vPersonList);
