Description Dirk Beetstra 2006-10-21 14:21:43 UTC
Error message when calling either $wgTitle or $wgOut->addWikitext (but not addHTML!):

$wgTitle results in: Call to a member function escapeLocalUrl() on a non-object in e:\\my 
homepages\\ChemWiki\\extensions\\Chemistry\\SpecialListPage.php on line 74

disabling this line gives:

Internal error

Created attachment 2530 [details]
the files giving the error

both SpecialListPage.php and SpecialChemicalsources2.php must be activated in
localsettings.php.  Calling the new specialpage (special:Chemicalsources2)
should result in the error.

Did you intend to resolve this as LATER?
Comment 3 Dirk Beetstra 2006-10-22 09:01:06 UTC
I'd still like to try and generalise the extension (see chemistry extensions in svn, the specialpage) 
further than I am currently capable of, but this seems not to be the way, problems in inheritage of 
classes, I guess.  Shortly, the thing has not been resolved, I don't know where or why it exactly breaks, 
and yes, I will try again and make it work, later.  I'll repost if I know whát goes wrong, and how to 
work around.
Comment 4 Aryeh Gregor (not reading bugmail, please e-mail directly) 2006-10-22 18:19:40 UTC
LATER is more for "it's not possible to do at present", because
standards/browsers don't support or whatever.  Like a bug opened asking for
routine inline SVG display or something.

Fixed in r40724
