Questions about dataface features/capibilities

[walterbyrd]

I read the features list, but there are a few things I'm not sure about.
- can dataface output grid be easily setup to sort on multi-keys: primary key, secondary key, etc?
- can dataface output grid be easily setup to hide specified fields?
- does dataface provide for rollbacks, even when using mysql (I don't think mysql has that feature built-in)?

1. Yes. All list views allow for sorting by clicking on any of the column headings.
2. Yes. visibility:list = hidden, visibility:browse = hidden -- or using permissions.
3. Yes and no. You can enable history in dataface which will effectively allow you to restore records to previous versions - and see the changes in records from version to version. Alternatively, you can use a mysql database engine that supports transactions (e.g. InnoDB) and use dataface triggers to implement your transaction support.
