title: Liferay Service Builder 6.2: Many to one relationships
body: <p>I want to create a one to many relationships and I've used the following service.xml:</p>
  
  <pre><code>&lt;entity name="Student" local-service="true" remote-service="true" cache-enabled="false"&gt;
      &lt;column name="studentId" type="long" primary="true" /&gt;
      &lt;column name="courses" type="Collection" entity="Course"/&gt;
  &lt;/entity&gt;
  
  &lt;entity name="Course" local-service="true" remote-service="true" cache-enabled="false"&gt;
      &lt;column name="courseId" type="long" primary="true" /&gt;
      &lt;column name="studentId" type="long"/&gt;
  &lt;/entity&gt;
  </code></pre>
  
  <p>My Problem is that nothing gets created for the collections method. No Exception, nothing.
  The classes are generated and the simple getter methods are there but no getCourse().</p>
  
  <p>What I am doing wrong?</p>
