Question

When I create a threaded discussion in another web it appears correctly at first but when I click on edit or comment. Things start to go down hill. Firstly the edit button takes me to the new page but the text area doesnt contain the text i want to edit. when I click save it pretends like its working but the content of the page changes to the following:

No permission to read topic "TopicName" - perhaps you need to log in? "EditedText".

the errors in the apache log are:

Note that the plugin works correctly when used in the Main web.

Any help would be much appreciated.

Answer

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

From the error messages I can see that you are using a relative path to search for the libraries. This can cause all sorts of issues. Please specify an absolute path in twiki/bin/setlib.cfg

Hi Peter.

I changed the setting in twiki/bin/setlib.cfg

Asim changed: $twikiLibPath = '../lib'; to $twikiLibPath = 'c:/twiki/lib';

I still got the error messages:

It seems as though the plugin works in any Web that does not use the viewauth script. But on inspection the viewauth script and view script are exactly the same except that viewauth is listed in .htaccess

-- AsimKhan - 31 Jan 2006

if ( ($TWiki::Plugins::ThreadedDiscussionPlugin::postxt eq "") && ($TWiki::Plugins::ThreadedDiscussionPlugin::pretxt eq "") ) {

this is the line it is crashing on in editthread. Line 68

-- AsimKhan - 08 Feb 2006

For some reason it seems as thought the variables in ThreadedDiscussionPlugin.pm are not being initialised when operating within an authenticated web.

-- AsimKhan - 10 Feb 2006

I fixed the bug by changing the source code of editcontrib.

Could you please post your change to the ThreadedDiscussionPluginDev topic?
