Item1224: Underscores in topic name with WebTopicCreator are not possible

TWiki bug topic: Item6209 ( src - history )

--

You cannot create topics with underscores in the names like Foo_Bar_Fooo with WebCreateTopic..even if you check "AllowNoWikiWord"...while you later still can rename it to have this name.

Seems like its simpy a JS validation problem, which does not respect the checkbox and simply converts the name to a WikiWord all the time

This has just been reported again as Item9195

There's some rather over-enthusiastic Javascript at work.

This is really crap; confirmed, and raised to Urgent status for 1.1 release.

Yes - this has come up multiple times in support questions as well. The JavaScript validations ought to match the same transform that is done by core when converting a bracketed spaced link into a valid topic name, allowing underscores, and some other limited punctuation permitted by core. It should also pick up $Foswiki::cfg{NameFilter} so that local preferences are uniformly enforced.

I've added a new PREFERENCE variable NAMEFILTER which copies the cfg{NameFilter} regex and passes it through EXPORTEDPREFERENCES to javascript. Added a new function filterPunctuation in addition to removePunctuation and changed webtopiccreator.js to follow the same rules as Render.pm. If the allow non-WikiWord checkbox is checked, then it Converts filtered punctuation to spaces, then remove spaces capitalizing the following letters to build a wiki word. If allow nonWikiWord is not checked, then the spaces and punctuation are all stripped as before.

I found one issue probably with our defaults. NameFilter default does not include #. But # is interpreted as an anchor and the Topic name is always truncated prior to the #. So we should probably add # to the NameFilter regex by default.

So...how would I access those changes you've made and incorporate them back into my site?

The changes are all listed at the bottom of this page, and can be reached by clicking on the "checkins". Unfortunately the changes are based upon other changes to version 1.1 of Foswiki and would need quite a bit of rework to fit them onto 1.0.9. 1.1 is getting close to a beta release.
