title: How to show non-persistent fields for an in-memory object in Apache ISIS?
body: <p>I have an Apache ISIS @Action that creates and returns a list of in-memory objects. When those objects are displayed by Apache ISIS as a collection in the browser - the JodaTime <code>DateTime</code> and <code>String</code> fields become all null.</p>
  
  <p>There is also another field on the object, which is a persistent entity - it does not get reset to null and is displayed on the object.</p>
  
  <p>Is it possible to display values of non-persistent fields of an object?</p>
  
  <p>EDIT: Apparently the <code>String</code> field is displayed. The <code>DateTime</code> are not though. Can this be an issue with <code>DateTime</code> specifically?</p>
