bindAggregation only returning the first element from a XML node

hello everyone,

investigating on this issue since fiew hours, I need your help (did not find a similar issue).

here is an xml sample:

<users>

     <useractive="true">

          <reference/>

          <name>

               <prefix/>

               <first>first</first>

               <middle/>

               <last>last</last>

          </name>

          <location></location>

          <identifier>

               <domain>mydomain</domain>

               <login>flast</login>

          </identifier>

          <email>

               <address>sample@email.com</address>

               <type>text</type>

          </email>

          <roles>

               <rolename="A"/>

               <rolename="B"/>

               <rolename="C"/>

               <rolename="D"/>

               <rolename="E"/>

               <rolename="F"/>

               <rolename="G"/>

          </roles>

          <groups>

               <groupname="A1"/>

               <groupname="A2"/>

          </groups>

     </user>

</users>

 

After having set the data in the table:

oModel.setData(data);                 

oTable.setModel(oModel);  

oTable.bindRows("/user");

I am able to bind correctly properties like first name & last name in my table... but I am not able to do a bindAggregate on roles !

When I do this, only the first role is returned everytime for each row.

With the example above,

It displays, : first as firstname, last as lastname, & only role A instead of displaying all roles from A to G as above in the xml.

Here is the bindAggregation:

oTable.addColumn( new sap.ui.table.Column({

     label: new sap.ui.commons.Label({text: "Roles"}),

     template: new sap.ui.commons.ListBox({  

          "items": {     

               path: "roles",

               template: new sap.ui.core.ListItem({text: "{role/@name}",})

          }

     }) ,

}));

Where is my misunderstanding ? or how should I deal for having all roles displayed correctly in the listbox of this column ?

No proposal ?

Really thank's in advance to each of you for your coming help,

Best Regards
