Newly created sub-folder not available for moving into until after Thunderbird restart

[LinuxOnTheDesktop]

I had a local 'Products' folder. I added a new subfolder to it - let's call that subfolder 'new'. I went to move an item (in a sentmail folder) into 'new'. I tried to do that by way of a QuickFolder tab that I have called 'Products'. But 'new' did not show within the 'Products' drop-down. I tried the drag several times. I was able to complete the operation after I restarted Thunderbird.

QF 6.6.1
Thunderbird 115.13.0 x64
Windows 10

thanks for reporting, is it a POP3 or IMAP account? I will see if I can reproduce it. I think there should be a folder listener for such things but I need to do some thorough testing.

Thanks. All my accounts are IMAP - but the folder is a local folder.

Just tried a quick test here but the child folder shows immediately here:

I can add some debug settings for you to test with...

[LinuxOnTheDesktop]

Thanks. What exactly did your test do, though? Did you merely click 'parent'?

Here is what happens when I click 'Products' (with red background being redaction):

sorry I see the screenshot, it just shows an empty folder (no messages) and you have subfolders shown in the folder tree (on the left), what do you expect to be different?

Hi Axel

I have confused things. Here is how.

Initially, I expected . . what I described in my first post. To wit: I expect that dragging to a QF tab will reveal a list, near the tab, of subfolders. Subsequently and erroneously I came to expect that, when I click a QF tab, a list of the relevant folder's subfolders will appear. That latter expectation is erroneous is that I base it, I think, on something that I merely thought I remembered.

The problem that I reported initially still stands - though it seems you have not managed to reproduce it.

this is correct: dragging should popup the subfolders as drag targets:

To get a full recursive list of all subfolders make sure to enabled "Expand subfolders...." in the Behavior section of general settings.

Subsequently and erroneously I came to expect that, when I click a QF tab, a list of the relevant folder's subfolders will appear.

yes - but only if you right-click the tab. clicking just activates the folder. Ctrl+click opens it in a new Tab. Keeping it as simple as possible with a normal click is one of the premises that makes QuickFolders successful.

That latter expectation is erroneous is that I base it, I think, on something that I merely thought I remembered.

Yeah I need to do some additional testing and look at what the code does here and how it could fail. For performance reasons the subfolder popup are not necessarily generate on click but cached, however there must be conditions when they are re-generated.

I have a general FolderListener that handles added folders by force-adding them to MRU via a timestamp (util.touch(fld || f))

I could potentially search all parent folders of their path to check whether they are in a QF tab and force recreating the popup menu at this stage, as relatively speaking it won't take too much performance when creating new subfolders. If would be much worse to do while dragging mails over multiple tabs.

  onFolderAdded: function(parent, item) {
    try {
      if (!QuickFolders) return;
      const util = QuickFolders.Util,
            Ci = Components.interfaces;
      let f = item.QueryInterface(Ci.nsIMsgFolder);
      util.logDebugOptional("listeners.folder", "onFolderAdded\n" + f.prettyName + "\n"  + f.URI);
      let fld = QuickFolders.Model.getMsgFolderFromUri(f.URI, true);
      if (!parent.flags & util.FolderFlags.MSG_FOLDER_FLAG_TRASH) {
        util.touch(fld || f); // set MRUTime, unless folder was deleted.
      }
      QuickFolders.FolderListener.lastAdded = f;
    }
    catch(e) { };     
  },
