Problem configuring webviewer properties with WebSVN

Hello,

I have been trying to configure the webviewer: properties to work with WebSVN. I have configured the following two properties on my directory:

webviewer:pathrevision
/websvn/psi/listing.php?repname=psi&path=%PATH%&rev=%REVISION%
Added: webviewer:revision
/websvn/psi/listing.php?repname=psi&rev=%REVISION%

Subversion and WebSVN share the same hostname.

When I open the Log Messages viewer, from the revisions pane I can select:

* View revision in webviewer - this takes me to the root of my repository at the specified revision.
* View revision for path in webviewer - this takes me to the parent directory from which I opened the Log Messages viewer (e.g. if I clicked on ^/DirA/DirB, then WebSVN opens in DirA.

However, if I select a file from the lower pane (as in the attached screen capture) and select 'View revision for path in webviewer', nothing happens.

Any help with reviewing my webviewer: properties or pointing me to some debug resources would be greatly appreciated!

I'm using the latest release of TSVN (1.6.4, Build 16808 - 64 Bit , 2009/08/06 07:26:35).

Thanks,
- Ryan
