> I am trying to retrieve objects within a SharePoint 2013 library, using "=
IFolder.GetChildren(=E2=80=A6)"
> In plain libraries this is working OK. But when the SharePoint library co=
ntains folders, the function always raises a NULL-Pointer-Exceptions.
> 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, se=
e stacktrace below.
> Note 1: Using the CMIS Workbench (same connection parameters and same cre=
dentials) documents AND folders are listed correctly (!)
> Note 2: I already tried to add some code which simply avoids NULL-argumen=
ts. This does NOT help,  just an empty result will be returned.
> Note 3: A similar behavior occurs when trying to access objects using "IS=
ession.GetObjectByPath()" --> rootFolder and documents are OK, subfolders w=
ill 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
