[dev] best coding practices with Horde_Views

I don't really completely follow your description of the code  
structure - and I'm not sure where you are trying to access $injector  
- but as far as "there is no $injector variable" - if this code is  
within some non-global scope, you'll need to use $GLOBALS['injector']  
(or declare the $injector variable as global).
