No collection found

[Theo van Loon]

Hello all,

i have a problem :

here are some snippets of the code to show you what;s going on :

struts-config.xml :

<action 
  path="/catalog" 
  type="actions.GoToCatalogAction" 
  name="catalogForm"
  scope="session">
  <forward name="success" path="view.catalog" />  
</action> 

Form :

public class CatalogForm extends ActionForm
{
private Collection productList;
public AntenneForm()
{
super();
log.debug("--- AntenneForm CONSTRUCTOR--- ");
}
 
    /**
     * @return Returns the productList.
     */
    public Collection getProductList()
    {
        return productList;
    }
    /**
     * @param productList The productList to set.
     */
    public void setProductList(Collection productList)
    {
        this.productList = productList;
    }
}  

Action :

public ActionForward executeAction(ActionMapping mapping,
            ActionForm form, HttpServletRequest request,
            HttpServletResponse response) throws ApplicationException
    {
        log.debug("--- Start execute ---");
        
        CatalogForm catForm = (CatalogForm) form;
        TestClass test = new TestClass();
        
        String id = request.getParameter (ApplicationConstants.CONTEXT_GENRE_ID);
        
        List productList = new LinkedList();
        if (id == null)
        {
            // The product that are new in stock will be displayed.
            productList = test.getProducts();
        } 
        else
        {
            // Based on the id of the genre the appropriate products will be displayed.
Genre genre = test.getGenre(new Integer(id).intValue())
            productList = test.getProducts(genre);
        }
        
        if (antenneForm.getGenreList() == null)
        {
            List genreList = new LinkedList();
            genreList = test.getRankedGenres();
 
            // Set the genre list in the form.
            antenneForm.setGenreList(genreList);
        }
 
        antenneForm.setProductList(productList);

Jsp :

%@ include file="/jsp/webshop/pageLayout/common.jsp" %>
  <logic :-P	 resent name="catalogForm" property="lastUpdate">
<h2 class="white">
  <bean:message key="new.header" />
</h2>
<h2 class="white_italic">
  <bean:message key="new.update" />
</h2>
<h2>
<bean:write name="catalogForm" property="lastUpdate"/>
</h2>
  </logic :-P	 resent>
 
  <html:form action="/addToCart">
      <logic:iterate id="product" name="catalogForm" property="productList">  

I keep getting the no collection found message when i had it working before.
I do exactly the same for another collection and it works just fine. Can't seem to find what's wrong. The collection returned by the TestClass is filled so that's not the issue.

Thanks for your help a lot!!

            antenneForm.setGenreList(genreList);
        }
 
        antenneForm.setProductList(productList); 

You use the variable antenneForm, but I don't see where this gets initialized. Do you mean to use catForm instead?

Well, the first thing that could be a problem, is that your contstrutor for the CatalogForm is called AntenneForm.

Shouldn't it be:

 public class CatalogForm extends ActionForm
{
private Collection productList;
public CatalogForm()
{
super();
log.debug("--- CatalogForm CONSTRUCTOR--- ");
}

No that's not it, i changed the name from AntenneForm to CatalogForm so it would be more clear for you. I didn't change it everywhere. I set the collection in the form in my Action. But when it reaches the jsp it seems to be null...
