title: Objectbox not saving list of objects
body: <p>I'm attempting to save a custom object (called Data) that contains a list of (Datafield) objects. When i use the objectbox browser admin i am unable to see the column for the data at all and only see the UID listed under relations but not in the Data object definition of the json
  Here is the code i have for a Data object</p>
  <pre><code>@Entity
  data class Data(
      @Id
      var id: Long = 0,
      var name: String = &quot;&quot;,
      var lastEdited: String = &quot;&quot;,
      var dataFields: List&lt;DataField&gt; = listOf(),
  )
  </code></pre>
  <p>and here is the code i have for a Datafield object</p>
  <pre><code>@Entity
  data class DataField(
      @Id
      var id: Long,
      @Unique(onConflict = ConflictStrategy.REPLACE)
      var fieldName: String = &quot;&quot;,
      var dataFieldType: Int = DataFieldType.SHORTSTRING.ordinal,
      var dataValue: String = &quot;&quot;,
      var first: String = &quot;&quot;,
      var second: String = &quot;&quot;,
      var third: String = &quot;&quot;,
      var isEnabled: Boolean = true,
      var fieldHint: String? = &quot;Enter value for $fieldName&quot;
  )
  </code></pre>
  <p>one Data object should contain a list of Data field objects.  I've rebuilt my objectbox model and deleted the in app data/cache on the virtual device all to no avail.</p>
