Hello
I have a big problem with nested table, here is my
case.
I have an ArrayList named listeDeProduits which
contains somes objects named "Produit" and each
object "Produit" have an ArrayList named "endroits"
which contains somes object named "Endroit".
My ArrayList "listeDePoduits" has been set to the jsp
file with session.setAttribute("listeDeProduits",
listeDeProduits);
In my jsp file, i have this :
<bean:define name="listeDeProduits" id="liste" />
<display:table name="sessionScope.listeDeProduits" id
= "IDproduit">
<display:column property="nom" title="Nom" />
<display:column title="Addresses">
<--! the "endroits" property is PUBLIC but if i set it
in PRIVATE and if i use a getter to get it, i got the
same error message -->
<--! I put the static number 0 (whith another number,
i got the same error message) only for the debugging
of course -->
<display:table
name="<%="(sessionScope.listeDeProduits).produit[0].endroits"%>"
id="child" >
<display:column property="ville" title="Ville"/>
</display:table>
</display:column>
</display:table>
If when i disable the display of the nested table, ALL
IS OK.
But if i display the nested table, i get this message
at the emplacement of my nested table "Nothing found
to display."
If i do this :
<%
System.out.println(((Endroit)((((ArrayList)((Produit)(((ArrayList)liste).get(0))).getEndroits())).get(0))).getVille());
%>
I got the value of the property Ville which is a
member of an Endroit Object.
But when i do :
<% System.out.println("endroits = " +
((Produit)(((ArrayList)liste).get(0))).endroits); %>
I got : "endroits = [EMAIL PROTECTED]" in my
Catalina.out
And after each loading of the jsp file, only the
string after the "@" change.
I dont know how i got a string like
"[EMAIL PROTECTED]" and i don't understand why
the nested table can't view "endroits" sublist.
As substitut for the line :
<display:table
name="<%="(sessionScope.listeDeProduits).produit[0].endroits"%>"
id="child" >
I have also tried these lines but i get the same error
:
<display:table
name="<%="listeDeProduits.produit[0].endroits"%>"
id="child" >
<display:table name="<%="liste.produit[0].endroits"%>"
id="child" >
<display:table name="<%="(liste.get(0)).endroits"%>"
id="child" >
<display:table
name="<%="(listeDeProduits.get(0)).endroits"%>"
id="child" >
Don't forget that when i display ONLY the parent
table, all is ok.
Thanks for any helps. This problem is VERY VERY
important for me.
Here is my code of my "Produit" class :
=======================================
package models;
import java.util.*;
public class Produit
{
private String nom = "";
public ArrayList endroits;
public ArrayList getEndroits()
{
return endroits;
}
public void setEndroits(ArrayList endroits)
{
this.endroits = endroits;
}
public String getNom()
{
return nom;
}
public void setNom(String nom)
{
this.nom = nom;
}
}
Here is my code of my "Endroit" class :
=======================================
package models;
public class Endroit
{
private String ville = "";
public String getVille()
{
return ville;
}
public void setVille(String ville)
{
this.ville = ville;
}
}
