[jira] [Updated] (OLINGO-1045) ODataEntry with expanded link does not have the next link URL

     [ https://issues.apache.org/jira/browse/OLINGO-1045?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

M Carissimi updated OLINGO-1045:
--------------------------------
    Description: 
I am writing an OData consumer using Olingo and I have an issue with expanded links. 
I request data from an OData service using the $expand option
{code}
/odata/resource.svc/TEST_PRICE_CODE('P-1')?$expand=TEST_PRICE_QUOTE_link
{code}

This results in an entry containing an inline feed with a next link:
{code}
<entry xmlns="http://www.w3.org/2005/Atom" ...>
 <link href="TEST_PRICE_CODE('P-1')/TEST_PRICE_QUOTE_link" ...>
  <m:inline>
  <feed ...>
    <entry>
      ...
    <entry/>
    ...
    <link href="http://xxx/odata/resource.svc/TEST_PRICE_CODE('P-1')/TEST_PRICE_QUOTE_link?$skiptoken=10" rel="next"/>
  </feed>
  </m:inline>
 </link>
...
</entry>
{code}

I read this entry via Http and I construct the ODataEntry using the EntityProvider.readEntry() method, but when I then try to obtain the next link from the inline feed, the next link is missing:
{code}
...
      EdmEntityContainer myEntityContainer = theEdm.getDefaultEntityContainer();
      myEntry = EntityProvider.readEntry(aContentType,
          myEntityContainer.getEntitySet(anEntitySetName),
          myHttpResponse.getEntity().getContent(),
          EntityProviderReadProperties.init().build());
String myNextLink = ((ODataDeltaFeed)myEntry.getProperties().get("TEST_PRICE_QUOTE_link")).getFeedMetadata().getNextLink());
{code}

Why is the next link not present in the ODataDeltaFeed instance within the ODataEntry constructed from the InputStream of the content read via HTTP?
