Florian Müller commented on CMIS-647:
-------------------------------------
The NPE is caused by the missing ID in the Atom entry (-> "Received Atom entry
is not a CMIS entry!").
For further analysis I'd need the Atom response from the SharePoint server.
> Exceptions when trying to access SharePoint 2013 folders
> --------------------------------------------------------

> Key: CMIS-647
> URL: https://issues.apache.org/jira/browse/CMIS-647
> Project: Chemistry
> Issue Type: Bug
> Components: dotcmis
> Affects Versions: DotCMIS 0.5
> Environment: Windows 7 Professional
> Reporter: Thomas Rogall
> Assignee: Florian Müller
>
> I am trying to retrieve objects within a SharePoint 2013 library, using
> "{IFolder}.GetChildren(…)"
> In plain libraries this is working OK. But when the SharePoint library
> contains folders, the function raises a NULL-Pointer-Exceptions occur every
> time.
> After removing all folders from the SharePoint library the function works
> correct again.
> The NULL pointer exception is caused in "binding-caches.cs", line 220, see
> stacktrace below.
> Note 1: Using the CMIS Workbench (same connection parameters and same
> credentials) documents AND folders are listed correctly (!)
> Note 2: I already tried to add some code which simply avoids NULL-arguments.
> This does NOT help, just an empty result will be returned.
> Note 3: A similar behavior occurs when trying to access objects using
> "{ISession}.GetObjectByPath()" - rootFolder and documents are OK, subfolders
> will raise exceptions.
> Sample output from my test program:
> Path '/' --> Folder: Meine erste Bibliothek
> Path '/NOTEBOOK.JPG' --> Picture: NOTEBOOK.JPG
> Path '/AAA' --> EXCEPTION: Received Atom entry is not a CMIS entry!
> Path '/AAA/' --> EXCEPTION: Received Atom entry is not a CMIS entry!
> Path '/AAA/BBB' --> EXCEPTION: Received Atom entry is not a CMIS entry!
> Path '/AAA/BBB/JUDGESCH.GIF' --> Document: JUDGESCH.GIF
