I have a form I've been using on my SMW installation for a while, but I
recently broke it. I would like to figure out how to un-break it, but so
far I've been unsuccessful. This is pretty high priority for me, so any
help would be appreciated.
The error message can be seen
here<http://stg.ropewiki.com/index.php/Special:FormEdit/Canyon/asdf>;
it is:
Notice: Undefined property: stdClass::$mParent in /var/www/
stg.ropewiki.com/extensions/SemanticResultFormats/formats/tree/SRF_Tree.phpon
line 146 Notice: Undefined property: stdClass::$mParent in /var/www/
stg.ropewiki.com/extensions/SemanticResultFormats/formats/tree/SRF_Tree.phpon
line 146 Catchable fatal error: Argument 2 passed to
SRFTree::printElement() must be an instance of SRFTreeElement, instance of
stdClass given, called in /var/www/
stg.ropewiki.com/extensions/SemanticResultFormats/formats/tree/SRF_Tree.phpon
line 156 and defined in /var/www/
stg.ropewiki.com/extensions/SemanticResultFormats/formats/tree/SRF_Tree.phpon
line 162
When things were working properly, I was on some unknown changeset of the
master branch of Semantic Results Formats because the way I obtained SRF
was to simply do a git clone
https://gerrit.wikimedia.org/r/p/mediawiki/extensions/SemanticResultFormats.gitand
nothing else. I recently changed SRF versions by doing a git checkout
on the REL1_21 branch because I thought that might fix a different problem.
Unfortunately, by the time I noticed this problem, I had lost any
indication as to what changeset I used to be on. I've tried switching to
the 1.8.x branch, the REL1_21 branch, and the master branch. The first two
have the same problem and the master is totally fubar (as expected, because
my MW and SMW versions are too low for the latest).
The problem appears to be a format=tree #ask query I have in the form
input. The pertinent line is:
{{#ask: [[Category:Regions]] |format=tree |parent=Located in region
|limit=1000 }}
When I change that line to:
{{#ask: [[Category:Regions]] |format=list |parent=Located in region
|limit=1000 }}
...the problem resolves. You can see the results of the latter query
here<http://stg.ropewiki.com/index.php/Sandbox>,
but it seems I can't save a page containing the former query (though it
already exists embedded within the Form:Canyon page).
Any ideas would be greatly appreciated.
Thanks!
