What happens if asserts are off? Because this assert actually looks like reasonable behaviour to me, in "debug" mode.

-- CrawfordCurrie - 20 Jul 2010

with Asserts off, Foswiki opens the editor on the Main/WebHome topic.

Rather than going to edit with the wrong topic, using an incorrectly formatted webname should probably return the same error as using a correctly formatted, but missing webname.

Web/topic validations:

  • bin/view/asdf/ -> Main/WebHome
  • bin/view/asdf/Blab -> Oops "(Missing or Illegal) web does not exist"
  • bin/login/asdf/ -> Main/WebHome
  • bin/login/asdf/Blab -> Assertion error
  • bin/login/asdf/Blab -> (Asserts disabled) Topic Blab does not exist (in Main web)
  • bin/edit/asdf/ -> Edit of Main/WebHome
  • bin/edit/asdf/Blab -> Oops "(Missing or Illegal) web does not exist"
  • bin/edit/ -> Edit of Main/WebHome
  • bin/attach/ -> Attaches a file to Main/WebHome
  • bin/attach/system/ -> Attaches to Main/WebHome

-- GeorgeClark - 20 Jul 2010

One other observation. Templates should show the explicit WEB.TOPIC in their headings, so the user can catch things like the incorrect attach.

-- GeorgeClark - 20 Jul 2010

Setting this back to New. This is also related to Item9284 and some other items regarding defaulting web/topic when lower case.

-- GeorgeClark - 28 Aug 2010

Note that on 1.1.3 without asserts, it results in the following error logged: 
Use of uninitialized value in -e at /usr/home/foswiki.org/public_html/lib/Foswiki/Store/VC/Handler.pm line 437.

-- GeorgeClark - 21 Sep 2011

Should be OK now

-- CrawfordCurrie - 18 Dec 2012

Some more breakage due to Foswikirev:16240 when saving attachments. Only trunk affected.
