I have a requirement for users to be able to modify certain attributes in
the User App. For example, users should be able to modify their phone
numbers. As far as I can see the ACLs are setup correctly because
when I login as that user to iManager I can edit the phone number field.

When I login to the User App as that same user and view the Detail portlet
it displays the field as editable, but when I try to save my change after
editing the phone number attribite a pop up window appears and just says
[Object Error].

Has anyone else experienced this error and if so what is the fix?
