Add a note about the duplicate link with OFBIZ-2353
=====================================================
Jacopo,
I just quickly read the 1st lines of your last comment, and I think it should
be noted here the relation with OFBIZ-2353 (SequenceUtil may generate duplicate
IDs in Load Balancing mode). Ha, I just see that this issue is marker as its
duplicate. Not sure it's completly the case because, apart maybe the SELECT FOR
UPDATE solution, the solutions proposed in OFBIZ-2353 do not guarantee enforced
sequences.
Just noticed that [Adrian already reported it in a comment
above|https://issues.apache.org/jira/browse/OFBIZ-3557?focusedCommentId=12870058&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12870058].
Anyway I already removed the duplicate lin

> Key: OFBIZ-3557
> URL: https://issues.apache.org/jira/browse/OFBIZ-3557
> Project: OFBiz
> Issue Type: Bug
> Components: framework
> Affects Versions: Release Branch 09.04, SVN trunk
> Reporter: Wickersheimer Jeremy
> Attachments: OFBIZ-3557-1.patch, OFBIZ-3557-2.patch
>
>
> There is a fundamental issue with enforced sequences (for orders, invoices,
> etc ..) and concurrency.
> For example if two users are creating an order at the same time one of them
> will see the creation fail with a PK error. The problem is that the
> "getNextXXXId" rely on the party accounting preference entity, but there is
> absolutely no guarantee that the last number in the sequence gets updated
> before another service can read it.
> This is at best very annoying when used only internally but may be
> unpractical for e-commerce sites.
