Threads don't contain all posts when opened in the Forum View using the arrow icon RRS feed

  • Question

  • Hi,

    after the forum updates this weekend, if one is opening threads using the arrow icon to the left of the thread title in the forum view, the expanded thread view doesn't always contain all posts. It can happen that the post shown as most recent post in the summary is not visible in the expanded thread view, and other posts might be missing, also. When opening the thread in thread view, the missing posts are shown.

    This behaviour has been observed in the WPF forum, using the hierarchical thread view.

  • Hi Ed,

    by the way, I experienced the same problem posting my reply to Naomi's post. Here are some more steps to reproduce, including a test I did in order to follow the idea that it might be related to stale caches:

    1. I read the thread by expanding it in the "my threads" view.

    2. I tried to post a reply using the reply link in Naomi's post

    3. The first try failed with the error message "undefined!" (that's another problem, though), so I copied what I had written to the clipboard and clicked the title of the thread in order to open it in thread view.

    4. I clicked reply again in thread view and posted the reply.

    5. I switched back to forum view following the breadcrumb link in the top navigation area.

    6. The thread summary showed me as the last contributor to the thread, now; it had shown Dave Patrick before.

    7. I expanded the thread using the arrow down icon next to the summary.

    8. My post was missing

    9. In order to check whether that had to to anything with caching, I signed out and closed all browser windows (I'm uisng IE 9, German, with current updates)

    10. I opened the browser again, signed in again and switched to "my threads"

    11. I expanded the thread with the arrow icon, as always.

    12. The post was visible, though out of logical sequence (It was at the end of the thread instead of under Naomi's post)

    I also noticed that the second time I click on the "expand thread" icon for a given thread in forums view, there is no "loading" animation, even though the thread and thread summary have changed meanwhile.

    Without knowing the internals, I'd recommend checking through the code that is responsible for loading / reloading and caching thread contents for display in forum view. Since you don't seem to have the same problem, it might be related to my browser's language version (yours is en-US, I assume), which would point into the direction of non-compatible time formats or something like that... however, without knowing more, that's all speculation.

    Anyway, thanks for following through so far,

    Regards,

    Hans

    I noticed the same behavior.
    One time my own reply didn't shown (and suspected an error on my side):
    http://social.msdn.microsoft.com/Forums/de-DE/vbasicexpresseditionde/thread/0d66571f-0c5a-457b-9ac5-09faa35aab84

    My first reply was shown after the second was made.

    Another one some minutes ago for user reply:
    http://social.msdn.microsoft.com/Forums/de-DE/vcsharpexpresseditionde/thread/ed9a71ac-9dfe-400f-bfa6-822bab624b29

    The notification arrived and the post was also visible in the NNTP-Bridge.
    But in the forum the message wasn't visible an hour later.
    After a test message by myself it came up.

    I think this may be a syncronization thing between brandings. ex Someone replies to post under technet and sometimes there's a delay in having it show up in same thread under msdn (or other) brand.

  • Hi,

    I don't think it's connected to different brandings, since I only use MSDN forums... I observed the problem several times during the last weeks. If I experience another example, I'll post here. However, since it seems to be transient in nature, it's probably hard to debug...

    Anyway, thanks for looking into this.

  • Hi,

    it's happening right now with the previous post. I wrote it in thread view. Then I switched back to forum view, using the breadcrumb link on top of thread view. The thread summary showed that the last reply was by me, however, when I clicked on the down arrow in order to expand the thread in forum view, the new post was missing.

  • I actually experience this problem when I post into the thread. I don't usually see replies that were posted while I was writing my reply. I need to re-load the thread to see all replies.

    Is it the behavior you're seeing?

  • That's interesting. It seems to come and go for me even reloading thread.

  • Hi,

    no, I dont't think that's it, either, since I am experiencing the problem mostly with my own posts, and I never write more than one at a time. Somehow, I have the feeling the problem might be related to stale caches for thread contents in forum view. (remember, the problem is distinctly related to forum view, in thread view, the missing posts show up). However, I don't know enough about the forum application's architecture to make educated guesses.

    Sounds like the server delay and synchronization problems Answers is having.   There at least we now have a diagnostic to let us know which server is involved...

    (Do a Find (e.g. Ctrl-F) for  next time   Answers does not allow us to capture arbitrary post Message-ID using right-click Copy Shortcut like this forum and the one I want to link to is older than 40 into the thread's unsubscribed RSS feed.)

  • Hi,

    yes, would be nice to have that here, too.

    Though, since closing the session and signing in again is a workaround, this here looks to me more like a client script problem than like a server side problem.
