Item10342: Failure in comparison of users, states and groups

In our Wiki we got the Problem that the states, users and groups cannot be compared. We always get the exception "No action available...". It seems that the Foswiki itself added some whitespaces. I could solve this by trimming the strings: $currentState, $thisUser and $allowed in the Workflow.pm with "s/^\s+//" and "s/\s+$//" -- MarceL - 11 Feb 2011

MarcelL - I recently had to trim whitespace elsewhere, so I'm thinking it's happening in core somewhere.

Can you please post an example of a comparison that (wrongly) fails? Thanks!

Hi Aaron, yes I think you are right. The Problem should be somewhere in the Core functions I think. Let me show you an example: In the Workflow.pm I made a debug output of the variable $currentState after the line: my $currentState = $topic->getState(); and there I get the output " CURRENTSTATE " - please take care of the whitespaces before and after the current state. It doesn't matter which action, state or user, except of the admin, I used. Everytime I got the problem. Therefore I trimmed the strings as mentioned here at this task. I hope you can understand what I mean here.

MarceL - I think this should be fixed as of WorkflowPlugin:3db8c4677cca. Can you try the latest SVN version of WorkflowPlugin, or provide STR so that I can try it?

Hah - looks like we commented at the same time! I committed the improved regex that BryanThale suggested in Tasks.Item10356, which should fix this, I think.

Also, feel free to join #foswiki on irc.freenode.net to discuss.

Thanks - We will check when we do the next update in our Wiki. For the moment it works with my workaround. Thanks a lot for the information and commiting the fix in the repository.
