This is a way to solve problems when an object ref and id isn't equals : for example id=99 and ref = 100.
This could happen since iTop 2.7.0, see https://www.itophub.io/wiki/page?id=2_7_0%3Arelease%3A2_7_whats_new#ticket_ref_generation
Note that id parameter can be set to the object's friendlyname as a workaround, but this might not be enough for some objects where friendlyname contains more that the ref field (for example title, org, ...)
* Admin console : new UI.php URL parameters : attcode and attvalue.
Example URLs :
/pages/UI.php?operation=details&class=UserRequest&id=99
/pages/UI.php?operation=details&class=UserRequest&attcode=ref&attvalue=R-000100
An exception will be thrown if no object is found or multiple instances are.
* User portal
New route : /object/view/{sObjectClass}/{sObjectAttCode}/{sObjectAttValue}
For example :
/pages/exec.php/object/view/UserRequest/99?exec_module=itop-portal-base&exec_page=index.php&portal_id=itop-portal
/pages/exec.php/object/view/UserRequest/ref/R-000100?exec_module=itop-portal-base&exec_page=index.php&portal_id=itop-portal
On error we will get a 404 error page
