Hi,
I've installed 2.3.0-rc1 (fresh install, CentOS 5) and it went fine. But when I log in with the admin account and go to view/modify content, I'm getting the following error in the right pane:
Fatal error: Argument 1 passed to DataObjectDecorator::updateCMSActions() must be an object of class FieldSet, called in /www/cms/sapphire/core/Object.php on line 475 and defined in /www/cms/sapphire/core/model/DataObjectDecorator.php on line 166
A 2.2.3 install works fine. Just wonder if this problem has been seen before.
