RE: Tag iterator and my object container
Hi,
Thank you. I implements the iterator interface, and now it is working.
public class SearchResults implements Iterator {
private Set keySet = null;
private Iterator iterator = null;
private Set keySet() {
if (this.keySet == null) {
this.keySet = this.results.keySet();
}
return this.keySet;
}
private Iterator iterator() {
if (this.iterator == null){
this.iterator = this.keySet().iterator();
}
return this.iterator;
}
public SearchResult get(String key) {
return this.results.get(key);
}
@Override
public boolean hasNext() {
return this.iterator().hasNext();
}
@Override
public SearchResult next() {
String next = this.iterator().next();
return this.get(next);
}
}
Calls (hasNext() and next()) are done in org.apache.struts2.components.
IteratorComponent

Re: Tag iterator and my object container
You could possibly get away with just implementing Iterable instead of
Iterator. It's a much simpler interface to implement.

Iterator tag and enumeration
Hi,
I have an enumeration 'Localization' :
public enum Localization {
AIX("Aix-en-provence"),
ANGERS("Angers") ;
}
And I want to put a form select in a jsp using s:select tag with all
Localization items, like :
But I don't know what to put in the list parameter.
In my Localization enum, I wrote a function to retrieve Localization item
through a sorted map :
public Map getListLocalization() {
[...]
}
So that my select will be like : Aix-en-provence
My question is finally : how to put an enumeration in a s:select tag ?
Thanks,
Matthieu MARC

RE: Iterator tag and enumeration
This code is working :
This one is not working :
Neither this one :
And neither this one :
I would be great to make the getListLocalization() work because I will be able
to have a nice display of select element.

Re: Tag iterator and my object container
You could probably get away with just exposing the map.

Jeff,
I am running struts 2.2.1
I also created this with Spring 3.0, although I am not sure I need spring.

I am trying to send an id from one action to another and it seems to be
sending a null. Please assist and I am really at my wits end with this.
How do I get the formId from the Listing to the QuestionListing?
startInformation has a yourForm=41, when I click the Begin button I get
the
redirect to Questions.action with a null formId as shown...
http://localhost:8080/IUNSurvey/survey/Questions.action?formId=
startInformation.jsp has a button that calls redirect:
...

public String execute() {
selectedForm = services.getFormsById(yourForm);
return SUCCESS;
}
public String display() {
forms = services.getForms();
return NONE;
}
public String beginQuestions() {
return "redirect";
}
/**

public Long getYourForm() {
return yourForm;

exerpt from QuestionListing.java
I have a getter/setter for formId
public String execute() {
currentQuestion = (services.getQuestionsByForm(getFormId()));
return SUCCESS;
}
public String display() {
setCurrentQuestion(services.getQuestionsByForm(getFormId()));
return NONE;
}
public void setFormId(Long formId) {
this.formId = formId;
}
public Long getFormId() {
return formId;
}

Sure.
* Is it "al", or "all"? You show both. IMO that's a bad idea--too
similar if they're supposed to be different.
* You say you pass three, get one. Which one?
* You say you pass three, get one; I only see two references to parameters.
* Is the URL being constructed properly? Check the HTML source.

Re: Iterator tag and enumeration
I dont quite get what exactly you want
if your getListLocalization has all the information of you Enum then you
probably just do list="listLocalization.entrySet"
but then you still need to provide the listValue and listKey attribute

getListLocalization() is a method of my Enum, not of my Action class.
