Re: [Jersey] Important bug found

Hi Paul,

Imagine having the following object-structure:

Folder has, among other fields, a list of Pages and a list of Keywords.
A Page has, among other fields, a list of Keywords.
A Keyword has an id and a name.

In this example we have and object model corresponding to the following xml:
<folder>
    <id>id:folder</id>
        <keyword>
            <id>id:keywordfolder</id>
            <name>name:keywordfolder</name>
        </keyword>
    <name>name:folder</name>
    <page>
        <id>id:page</id>
        <keyword>
            <id>id:keywordpage</id>
            <name>name:keywordpage</name>
        </keyword>
        <name>name:page</name>
    </page>
</folder>


The expected json output, using a provider that generates the jettison
format, is:
{"folder":
    { "id":"id:folder",
        "keyword":{"id":"id:keywordfolder","name":"name:keywordfolder"},
        "name":"name:folder",
        "page":
            { "id":"id:page",
               "keyword":{"id":"id:keywordpage","name":"name:keywordpage"},
               "name":"name:page"
            }
     }
}

However, the generated json was:
{"folder":
    { "id":"id:folder",
        "keyword":[ {"id":"id:keywordfolder","name":"name:keywordfolder"},
                            
*{"id":"id:keywordpage","name":"name:keywordpage"}*],
        "name":"name:folder",
        "page":{"id":"id:page"}
    },
  *"name":"name:page"*
}

As you can see the keyword belonging to the page object was put together
(in an array) with the keyword of the folder.
Besides this, the name of the page does not longer belong to the page
but is part of the folder.

I´ve attached a jersey application with a service that generates the
following output. It is using the newest version released: 1.0.1.
To use the service build the project, run BuggedServer.java and call the
url: http://localhost:8002/services/bug

We´re creating a business critical application based on jersey and are
facing this bug since the migration from version 0.8 to 1.0.
Do you have any idea how long it will take to fix it?

Hoping to hear from you,
Jeffrey
