[Jsdc-info] JSDC 1.2: Nested undo/redo (almost like real transactions)

[JSDC u. information. <jsd...@li...>]

Hi!

So, the undo/redo history is now a tree-structure and supports nesting.=20
This is to allow for a better user experience and security,=20
since functionality that implicitly creates a number of actions for each =
user action the functionality can group those actions and rollback in =
case of failure.
Also, when a user edits a tableview value, which in turn affects many =
other values, the user do not expect having to click "undo" 200 times, =
just because some triggered functionality updated 200 other values.

It is not called transactions, which i probably could have and gotten =
away with it, but histories is easier for people that have no database =
experience to understand.
So instead of begin transaction you write application.begin_history() to =
branch a subhistory that can be rolled back in case of failure.

The scope of the history will probably be expanded to encompass most =
objects that are used in web applications. Not only =
JSDC-database-connected ones, that is.
