The url to required rights entities are always the current page

Reproduction steps

1. login as Admin
2. create a page and add an object of type long text with a velocity macro in the content
3. login with a standard user (i.e., no script and programming rights)
4. edit the page

   Expected

   The url to the long text is a link to the object editor (e.g., http://localhost:8080/xwiki/bin/edit/Test/WebHome?editor=object&classname=AppWithinMinutes.TextArea&object=0)

Actual

The url is empty, consequently leading to the current page.
