Using the latest version, when trying to launch a session file (either with LogExpert not running or already launched) leads to a crash:

Invalid Content: ActiveContent must be one of the visible contents, or null if there is no visible content.

I can load the session just fine by using the File -> Load Session ... menu.

This problem does not exist with 1.5 / 4446.

Any ideas?

first of all thanks for the message, but I struggled to reproduce this behavior, could you please give some infos e.g.
  • OS
  • How many open files
  • Any filter created tabs
  • Large files?
  • Some files missing?
  • Columnizer
  • Version (I assume you use 1.6.0?)
  • Wich version you created the session file?
Steps to reproduce (Assuming, please correct me if something missing/wrong)
  1. Open some files
  2. Save Session
  3. Close Logexpert
  4. Start logexpert with doubleclick on lxj
  5. Error

Sure, here are the answers:
  1. Win 7 - 64-bit fully patched.
  2. No open files originally; one file to be opened by the session via UNC share.
  3. No filter created tabs.
  4. No large files (one file ~800k).
  5. No missing files.
  6. Columnizer is the RegEx Columnizer, built 8/27/2012 (maybe by me)?
  7. Version 1.5 / 5493
  8. Session file was saved using 1.5 / 4446 but resaved using 1.5 / 5493.
Reproduction 1
  1. Open a file via UNC path (\server\share\logfile.log).
  2. Change columnizer to use the regex columnizer with custom details (I can send this to you if needed.)
  3. Save session.
  4. Close LogExpert.
  5. Double click on lxj.
Error in first comment of this thread.

LogExpert stays running but the log file/session is not loaded; you are just left with a blank LogExpert window after the error dialog.

Same thing happens with the 1.6 alpha.

thanks for the infos, I will try to reproduce this behavior or if this doesn't work check the history of the changes. I hope to get started at the weekend. There waits a busy week for me ...

After some hours of testing and swearing I have a scenario that leads in all my tests to the error ...

So my steps to reproduce this error are:
  1. Remove or rename following folders:
    • %appdata%/logexpert
    • c:\Users\<user>\Documents\LogExpert\
  2. Open a file
  3. Activate Regex Columnizer
  4. Save Session e.g. test01.lxj
  5. Close Logexpert
  6. Remove extra lxp file in c:\Users\<user>\Documents\LogExpert\ created for the session
  7. Open session file (Logexpert open with blank window)
  8. Open same file
  9. Save session e.g. test02.lxj
  10. There opens another "Logwindow" focus this one (could be the file wich failed to load on first attempt)
  11. Save session e.g. test02.lxj
  12. Close Logexpert
  13. Open Session file
  14. Error
Next step will be to trace down the bug and fix it ;) One of my candidates to check is this "ghost log window" that appears after saving the session.

not that good updates, this problem got me some serious headcaches. I found some more problems that need to be fixed first. Before I can start with this problem.

Thanks for the update. I'm sticking with the older version for now.
