Does this site look broken?. Use the LitterTray web for test cases.

(Copied from TWiki:Codev.HeaderRenderingWithWikiWordsBroken)

Headers with WikiWords don't render correctly in Dakar. This behavior seems to have appeared before the MultiLevelWikiWebs merge.

Test case

This code:

---+++ WebPreferences will break this header

Currently renders like this:

WebPreferences will break th"> WebPreferences will break this header


TWiki version: TWikiAlphaRelease
TWiki plugins: DefaultPlugin, EmptyPlugin, InterwikiPlugin
Server OS: OS X 10.3
Web server: Apache 1.3.33
Perl version: 5.8.1-RC3
Client OS: OS X 10.3
Web Browser: Firefox 1.0.4

Follow up

Looks like WikiWords are getting expanded inside header markers (the <a name="header text"></a> thingy):

---+++ WebPreferences will break this header

produces this:

<h3><a name="<a href="http://g5/dakar/bin/view/Sandbox/Test2/WebPreferences 
class="twikiLink">WebPreferences</a> will break th"></a> <a 
class="twikiLink">WebPreferences</a> will break this header </h3>

Thanks Peter. Looks like TOC is proken on Cairo too, judging from the TOC at the top of the page.

BTW, could you report problems to the Bugs web rather than here, please? It saves them getting lost. Thx

I think it's just picking up the H3 tag I used in the test case. I'll re-file in the bugs web.

Double-bracket links are not being filtered from the anchor name, and are subsequently rendered. Removing the double-brackets from the anchorName seems to fix the problem. Here's a patch for Render.pm

This patch passed necessary testing and has been applied to the DEVELOP branch.
