That should work... so maybe also try setting your Apache user (usually 'www-data') as the owner of /runtime? Something like:

 chown -R www-data:www-data /var/www/html/demo/protected/runtime

Could be an Apache umask issue also. Check out the Yii forum, which has helpful posts like this one: http://www.yiiframework.com/forum/index.php?/topic/19400-question-about-directoryfile-permissions/

You should NOT have to set your whole project to 777, that is very insecure. I think /assets and /protected/runtime are the only directories that need write permissions (775).
