Does this site look broken?. Use the LitterTray web for test cases.

In a plugin topic (ThreadedDiscussionPlugin, but that is not relevant) I had set an ICONTOPIC flag. In this topic, suddenly TWiki::mapToIconFileName would mess up.

It appears that the plugin specific variables are not isolated in their own name space, as in that topic a call to getPreferencesValue from TWiki in getIconUrl ends up finding the plugin variable.

To test, just set a variable in a plugin topic (say ICONTOPIC) to something. In my case, I used

  • Set ICONTOPIC = %PUBURL%/%TWIKIWEB%/TWikiDocGraphics

Actually, it is relevant. As you know, plugin preferneces get the name of the plugin prepended, so when viewing from another topic, your ICONTOPIC setting would be THREADEDDISCUSSIONPLUGIN_ICONTOPIC. Onyl when viewing the actual plugin topic is there a clash, because the setting is identified as a TOPIC level setting of ICONTOPIC.

My advice is (unless Cairo compatibility is a primary concern) to move all settings out of plugin topics and into LocalSite.cfg, where they can be set from configure. There is an interface available to installers to support this (though I confess poorly documented at the moment).

It works as per spec. Discarding. if you want to change the spec, raise a topic in Codev.
