Re: [Wicket-user] How can I get the value of TextField in a table

[Johan Compagner]

i find youre code a bit strange and not so clean i would do this:

implement getListItemModel of the listView and make a CompoundModel for that listitem

            protected IModel getListItemModel(final IModel listViewModel, final int index)
            {
                return new CompoundPropertyModel(super.getListItemModel(listViewModel, index));
            }

then in populate item:

   listItem.add(new Label("name"));
   listItem.add(new Label("description"));
   listItem.add(new Label("sponser"));
   listItem.add(new Label("price"));
   listItem.add (new Label("id"));
   listItem.add(new Label("promotion"));
   listItem.add(new TextField("amount"));

   Link buyLink = new Link("buyLink")
   {
           public void onClick()
           {
             setResponsePage(new MyCart((ProductList)listItem.getModelObject()));
           }
      
           public boolean linksTo(Page page)
           {
             if (!(page instanceof MyCart))
               return false;
             return true;
           }
         };
         listItem.add(buyLink);
