Description
Steps to reproduce:
1. Create a class XWiki.FooClass
2. Add a property content of Computed Field type
3. Add an XWiki.FooClass object to a page (Main.WebHome)
4. Access the object with REST: 127.0.0.1:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome/objects/XWiki.FooClass/0
Expected result: The object information should be displayed in an XML format like it does for 127.0.0.1:8080/xwiki/rest/wikis/xwiki/spaces/XWiki/pages/Admin/objects/XWiki.XWikiUsers/0
Actual result:
