ACL rules (change order with drag and drop)
URL: https://github.com/apache/cloudstack/pull/2511#issuecomment-386326837
Ok, I see what you did there.
Our goal was not to tackle concurrency problems with that new API method. We
have not had these problems so far. The idea was only to fix the drag and drop
sorting/limitations. I can put this in my backlog, and look for a way to tackle
it as well. However, I would prefer a new method to maintain backward
compatibility of that “update” method.
BTW: can I open a transaction in the service (manager) layer? I really do
not like the idea of putting logic in DAOs. If we were using spring to manage
DAOs and transaction we would have `@Transactional` annotation. I see that in
ACS some parts of the code use `@DB`, will it open a transaction for methods
annotated with it?

> An error is happening in certain conditions, such as when you have only 2 ACL
> rules and you move the last one to the top. There are other conditions, for
> instance, when moving ACLs that are in a sequence of numbers without gaps.
> Example, rules:
> number | rule
> 1 - rule A
> 2 - rule D
> 3 - rule B
> 4 - rule C
> 5 - rule E
> It is not possible to move "rule C" in position 2, 1, and 3.
