[jira] [Commented] (GEODE-2349) Region.values() doesn't work properly inside JTA

Eric Shu commented on GEODE-2349:
---------------------------------

This is fixed now (as of Geode 1.4.0) by making region set operation transactional even if it is the first operation. See GEODE-3521.

> I experienced rather strange error invoking Region.values() within JTA transaction: {{java.lang.IllegalStateException: The Region collection is not transactional but is being used in a transaction}}.
> Doing some investigation I think I understand what is the cause of this error. Everything works if {{Region.values()}} invoked alone in transaction but failed if you invoke, say, {{get()}} on another (or the same) region before starting iteration over the collection returned by {{values()}}. I think that the reason of this error is the absence of {{discoverJTA()}} in {{values()}} method. So, when {{values()}} invoked first time {{EntriesSet}} is created with {{myTX = null}} since no transaction is determined (as soon as {{discoverJTA()}} is not invoked). If you are iterating immediately everything works as soon as there are no transaction on a region still ({{EntriesSet.myTx = null && topRegion.isTX() = false}}). But as soon as you invoke {{get()}} (or any other method where {{discoverJTA()}} is invoked) than all regions became transactional and next execution of {{EntriesSet.iterator()}} failed ({{EntriesSet.myTx = null && topRegion.isTX() = true}}).
