In CX2, attempting to publish an article with invalid characters in the title (Help:Page_name#Restrictions) will not result in any error messages:
CX1 will helpfully inform users about errors during publishing:
- "An error occurred while publishing the translation. Please try to publish the page again. Error: The requested page title contains invalid characters:..."
- "An error occurred while publishing the translation. Please try to publish the page again. Error: error"
The page will be stuck in "Publishing..." state. The Console displays the following error:
[CX] Invalid target title mw.cx.TranslationController.onTargetTitleChange oo.EventEmitter.emit ve.init.mw.CXTarget.onTargetTitleChange oo.EventEmitter.emit oo.EventEmitter.emit OO.ui.InputWidget.setValue (anonymous) setTimeout (async) OO.ui.InputWidget.onEdit dispatch elemData.handle
