title: How do I make a Grails criteria execute as a left join?
body: <p>I have a Grails criteria that has associated children classes that are nullable. I need to get all results, even those with null children, but the criteria gets executed with an INNER JOIN. How do I get it to be executed with a LEFT JOIN?</p>
  
  <p>Grails version is 1.3.7 (most recent), query is being executed via createCriteria().list</p>
