Hello.

We've finally managed to run the example successfully.

Here is how an attachment is created in the example:

private static void attachFile1(
    WorkItemWorkingCopy workingCopy,
    String name, String contentType,
    String encoding,
    IProgressMonitor monitor)
    throws TeamRepositoryException,
        IOException {
      
     File attachmentFile = new File(name);
     FileInputStream fis = new FileInputStream(attachmentFile);

     IWorkItem workItem = workingCopy.getWorkItem();
     IWorkItemClient workItemClient =

                 (IWorkItemClient) ((ITeamRepository)workItem.getOrigin()).getClientLibrary(IWorkItemClient.class);
     try {
            IAttachment newAttachment =
                 workItemClient.createAttachment( workItem.getProjectArea(),
                                                                        attachmentFile.getName(),
                                                                        "",
                                                                       contentType,
                                                                       encoding,
                                                                       fis,
                                                                       monitor);

            newAttachment = (IAttachment) newAttachment.getWorkingCopy();
            newAttachment = workItemClient.saveAttachment(newAttachment, monitor);
            IItemReference ref = WorkItemLinkTypes.createAttachmentReference(newAttachment);
            workingCopy.getReferences().add(WorkItemEndPoints.ATTACHMENT, ref);
     } finally {
           if (fis != null) {
                fis.close();
           }
     }
  }

}

Instead, we created the attachment like this, and it worked without the need to grant privileges on PA level:

private static void attachFile( WorkItemWorkingCopy workingCopy, String fileName)

             throws TeamRepositoryException, IOException {

             File attachmentFile = new File(fileName);

             IReference ref = IReferenceFactory

                                        .INSTANCE

             workingCopy.getReferences().add(WorkItemEndPoints.ATTACHMENT, ref);
