Most desktop UIs have an undo+redo feature.

The typical way to implement this would be by using the Command pattern (https://en.wikipedia.org/wiki/Command_pattern). However, the trouble with that pattern is that you need to create command objects for every kind of operation.

I'm curious if it would be possible to leverage the transaction log table and use roll-back to undo operations.

Has anyone tried this?

Thanks again for a great tool!

#2 mORMot 1 » Smart Mobile Studio (2.9.9 Alpha) Compatibility » 2017-12-26 19:39:38

I'm trying to use Smart Mobile Studio (2.9.9 Alpha) with mMORMot, but I'm getting compilation errors.

For example, "SynCrossPlatformREST.pas" line 804, which states that a const parameter cannot have a default value.

There are a number of other errors as well.

I've copied the appropriate SynCross*.pas files to the Libraries folder of SMS, so it's finding them correctly.

What am I missing?

Thanks!
