#9262 new defect

Error: Page tree does not exist

Reported by: christoph.ruediger@… Owned by:
Priority: normal Component: TocMacro
Severity: normal Keywords:
Cc: Trac Release: 0.12



Inside every yellow TOC block there is a red square at the bottom containing the error message "Error: Page tree does not exist". The yellow TOC block gets updated every time a change in the wiki occurs, so it seems to work properly on the main focus.

A screenshot is attached.

But what does the error message mean? And, more urgent, how to get rid of it?

Additional information

In the logs on DEBUG level I can find only one line with respect to the TocMacro:

2011-10-13 12:21:52,674 Trac[formatter] DEBUG: Executing Wiki macro TOC by provider <tractoc.macro.TOCMacro object at 0x2afe7e0665d0>

I can reproduce this behaviour in a new trac environment where only the TocMacro is enabled:

tractoc.* = enabled

The only difference to a complete default installation is, that I use MySQL as the DB backend.

My clean demo environment contains only the default wiki pages generated by the initenv command and the following modified/added demo pages:

  • WikiStart
    = MHC =
    [[TOC(MHC/*, tree, heading=Navigation)]]
    Short links:
     - [wiki:MHC]
     - [wiki:MHC/EMF]
  • MHC
    = Detail page for MHC =
    = What's the EMF? =
  • MHC/EMFRelease
    = What to do with an EMF release? =
    Step 1, 2, 3, ...

Currently I recognized that the generated links in the TOC block are sometimes wrong. I don't know how to reproduce this behaviour constantly.

Relating to the demo project above, the generated links are


But the correct links to the pages should be
