What is an invalid folderitem?

Sub NSURLMBS.Constructor(FolderItem)
Function folderItemUtils.FileIsOnlyIcloud(extends FolderItem) as boolean
Sub CheckMailExistingPDF.GetListOfFiles(FolderItem)

I’m checking if the file is in iCloud with NSURLMBS. The folderitem I get with a recursive FileListMBS.

Well, this is caused when NSURL internally is nil.
e.g. when folderitem is nil.
or if URLPath or NativePath are not returning a string.

The file directly comes from looping through FileListMBS:

dim theFileList as new FileListMBS(StartFolderitem)
dim FileCount as Integer = theFileList.Count - 1
for currentFile as Integer = 0 to FileCount
  
  dim theFile as FolderItem = theFileList.TrueItem(currentFile)
  if not theFileList.Visible(currentFile) then
    if theFileList.TrueItem(currentFile).FileIsOnlyIcloud then
      globals.theErrorLog.DialogErrorProceed(kErrorCloud.Replace("<<filename>>", theFileList.TrueItem(currentFile).DisplayPathMBS(" » ")))
      globals.StopArchiving = True
      exit for
    end if
  end if
  
  if theFile <> Nil and theFileList.Visible(currentFile) then
    if theFileList.Directory(currentFile) then
      GetListOfFiles theFile
    else
      dim FileEnding as String = theFile.NameExtensionMBS
      if FileEnding = "pdf" then 
        dim theAuthor as String = GetPDFAuthor(theFile)
        MessageIDs.Value(theAuthor) = theAuthor
      end if
    end if
  end if
  
next

The directory should only contain folders and PDFs.

Sorry, but there is no NSURLMBS used there?

5

Sorry, forgot the method name. FileListMBS calls the method theFileList.TrueItem(currentFile).FileIsOnlyIcloud where NSUrlMBS is called.

Well, I tried here:

Dim f As FolderItem = SpecialFolder.Desktop

Dim l As New FileListMBS(f)

Dim u As Integer = l.Count-1
For i As Integer = 0 To u
  
  Dim it As FolderItem = l.TrueItem(i)
  Dim n As New NSURLMBS(it)
  
  listbox1.AddRow n.absoluteString
Next

Works fine for me. I did make changes for TrueItem in pr6 or pr7, so maybe check again tomorrow and let me know if you have a case to reproduce.

The user has all her files on iCloud. I’ll re-test with the newer version of the plugin in the next days.
