Load errors are already handled in the MobileFrontend part of the
mobile visual editor, by this code:
66c55573e5/src/mobile.init/editor.js (L375-L387)
// Wait for the data to load before we show the editor overlay
overlay.getLoadingPromise().then( function () {
...
}, function ( error, apiResponse ) {
// Could not load the editor.
(1) overlayManager.router.back();
if ( error.show ) {
// Probably a blockMessageDrawer returned because the user is blocked.
document.body.appendChild( error.$el[ 0 ] );
error.show();
} else if ( apiResponse ) {
(2) mw.notify( editorOptions.api.getErrorMessage( apiResponse ) );
} else {
mw.notify( mw.msg( 'mobile-frontend-editor-error-loading' ) );
}
} );
Compared to our code:
ve.init.mw.MobileArticleTarget.prototype.loadFail = function ( code, errorDetails ) {
...
(1) this.overlay.onExitClick( $.Event() );
(2) mw.notify( this.extractErrorMessages( errorDetails ) );
};
The lines marked with (1) and (2) do basically the same thing. And
the function parameters "error, apiResponse" and "code, errorDetails"
are actually the same objects, just with confusingly different names.
This causes the popup with error message to appears twice (although it
isn't too obvious, since the two popups appear in the same place, so
only one is visible), and also causes bogus data to be sent in event
logging (T237063).
