title: Doctrine ORM error :  Unknown column type varchar requested
body: <p>Ok, so i just assigned a new project which uses Doctrine and Zend. This is my first time using Doctrine, and i came upon an error for which google didn't came up with any answer.
  I added a new field (VARCHAR 17) to a table, added getter/setter functions in the Entity for that table, then ran orm:generate-proxies.</p>
  
  <p>All good, except now i am getting this error when trying to save anything: Unknown column type varchar requested.</p>
  
  <p>Any thoughts?</p>
