I've deployed the Movie Rating dapp from the wiki
to my private network.
Now I can open Mist and browse to my localhost to access the frontend. On the upper right corner in Mist I activated 1 account. While it works to query for "Titanic" and getting a result, it has no effect when I enter another rating and click save. There's no (obvious) error neither at JS console nor geth nor mist console.
Have you experienced the same? And what could be wrong?
