body: <p>ormlite-android-4.29, ormlite-core-4.29</p>
  
  <p>I have a <code>ForiegnCollection</code> of PantryCheckLine objects like this in my PantryCheck class.</p>
  
  <pre><code>@ForeignCollectionField(eager = true, maxEagerForeignCollectionLevel = 1)
  private ForeignCollection&lt;PantryCheckLine&gt; pantryCheckLines;
  </code></pre>
  
  <p>Let's say I had 3 PantryCheckLines objects and I deleted one. Then I want to delete the PantryCheck with combined PantryCheckLines of it. Everything seems working. But the size of the <code>ForiegnCollection</code>is not correct.</p>
  
  <p>deleting method as follows.</p>
  
  <pre><code>PantryCheckLineRepo pantryCheckLineRepo =
      new PantryCheckLineRepo(DaoFactory.getPantryCheckLineDaoInstance());
  Collection&lt;PantryCheckLine&gt; pantryCheckLinesCollection =
      this.getPantryCheckLines();
  Log.v("pantrychecklines size", pantryCheckLinesCollection.size());
  pantryCheckLineRepo.delete(pantryCheckLinesCollection);
  Log.v("pantrychecklines", "deleted");
  </code></pre>
  
  <p>appreciate your help.</p>
