It seems that you use the an item name twice when you create the 
ResourceInput inside the modify method.

You might want to apply the following patch

diff --git 
a/resources/creatable-modifiable-deletable-v3/src/java/org/wyona/yanel/impl/jelly/ResourceInputImpl.java 
b/resources/creatable-modifiable-deleta
index 747b96c..c557e6d 100644

@@ -126,7 +126,7 @@ public class ResourceInputImpl implements 
ResourceInput {
          for (Iterator i = items.iterator(); i.hasNext();) {
              ResourceInputItem toCheck = (ResourceInputItem) i.next();
              if (toCheck.getName().equals(item.getName())) {
-                throw new IllegalArgumentException("Item with the name 
already exists");

'" + item.getName() + "' already exists");
              }
          }

inside git at github.com:wyona/yanel-contributions.git

in order to find out which item name is causing this conflict.
