[Using CM-SHOWCASE on connect-test]
Once the project is open, go to the project settings and change the target platform to 7.2
=> The chains that used Seam.Refresh are broken with the nice red alert: "The operation 'Seam.Refresh' referenced by this chain is not defined".
I suppose this is related to the new names (it's WebUI.Refresh now).
Put it on "Major" because even if it's easy to fix (go to each chain, drag-drop the "User Interface > refresh" operation), it can freak people out.
