Tried to install it on MW 1.31 and SMW 3.0. If I enable it, the extension does not recognize that SMW is installed. It displays that it needs SMW and quits.
Topic on Extension talk:Semantic Tasks/archive 2
I believe one of the reasons is that SMW switched to extension registration while this one expects "classic" registration. However even if this would not happen I am pretty sure that this extension will not work either due to other breaking changes in SMW 3.0
Indeed. If I remove the registration check, the extenson shows up in Special:Version without errors. But if I try to use it, the following error appears:
/index.php?title=Vorlage:Neuigkeit&action=submit Error from line 424 of .../extensions/SemanticTasks/SemanticTasks.classes.php: Call to private method SMW\DataValues\PropertyValue::makeUserProperty() from context 'SemanticTasksMailer' Backtrace: #0 ../extensions/SemanticTasks/SemanticTasks.classes.php(166): SemanticTasksMailer::getQueryResults(string, array, boolean) #1 ../extensions/SemanticTasks/SemanticTasks.classes.php(39): SemanticTasksMailer::getAssignees(string, string, User) #2 ../includes/Hooks.php(177): SemanticTasksMailer::findOldValues(WikiPage, User, WikitextContent, string, integer, NULL, NULL, integer, Status) #3 ../includes/Hooks.php(205): Hooks::callHook(string, array, array, NULL) #4 ../includes/page/WikiPage.php(1618): Hooks::run(string, array) #5 ../includes/EditPage.php(2214): WikiPage->doEditContent(WikitextContent, string, integer, boolean, User, string, array, integer) #6 ../includes/EditPage.php(1506): EditPage->internalAttemptSave(array, boolean) #7 ../includes/EditPage.php(652): EditPage->attemptSave(array) #8 ../includes/actions/EditAction.php(60): EditPage->edit() #9 ../includes/actions/SubmitAction.php(38): EditAction->show() #10 ../includes/MediaWiki.php(500): SubmitAction->show() #11 ../includes/MediaWiki.php(294): MediaWiki->performAction(Article, Title) #12 ../includes/MediaWiki.php(861): MediaWiki->performRequest() #13 ../includes/MediaWiki.php(524): MediaWiki->main() #14 ../index.php(42): MediaWiki->run() #15 {main}
It would have been nice to be proven wrong.
