Certain Web/Topic configurations appear to break Prefs::HASH as called by WorkflowPlugin.

  • Create a "Template" web beneath a real web. (ie. cp -a _default Sandbox/. )
  • Attempt to view the topic. =bin/view/Sandbox/_default/WebHome

With WorkflowPlugin enabled, Foswiki crashes in Frefs.pm. With WorkflowPlugin disabled, Foswiki issues an "oops". Access Denied - Attention - The "(Missing or illegal web)" web does not exist

Not sure if this is a bug in the Prefs that WorkflowPlugin exposes, or a bug in the plugin itself.

This happens if you have an invalid WebName (must start with capital letter), because the pushTopicContext / popTopicContext combo will fail.

You can insert a "return undef unless Foswiki::Func::isValidWebName( $web );" before line 95 in WorkflowPlugin.pm to disable the workflow in such webs.

Michael, Crawford. Can you review the suggested fix? I don't do much with WorkflowPlugin.

-- GeorgeClark - 24 Oct 2012

it was treating the symptoms, and not the cause. The cause was a lot more complex and involved.
