------------------------------------
Summary: Support pseudo nested JPA transactions and pre/post
commit hooks
Key: TAP5-2553
URL: https://issues.apache.org/jira/browse/TAP5-2553
Project: Tapestry 5
Issue Type: New Feature
Components: tapestry-jpa
Affects Versions: 5.4.1
Reporter: Kalle Korhonen
Plain JPA does not support nested transaction but by keeping track of
@CommitAfter stack, we can support "pseudo nested" transactions. The concept
was first demonstrated in https://github.com/satago/tapestry-jpa-transactions.
@kaosko started an effort to merge the codebase to T5
(https://github.com/satago/tapestry-jpa-transactions/pull/5) but because of
fundamental limitations in the original design (no support for multiple
persistence units, pre/post commit hooks were only available for the last
transaction), @kaosko refactored the implementation for more general use
(https://github.com/kaosko/tapestry-jpa-transactions). The original code was
under Apache license with support from the original authors to merge the
codebase to T5 and the refactored implementation was solely made by @kaosko.
This issue is about merging the refactored implementation to T5.5 and replacing
the existing JPA classes (mainly class workers, advisors) by the those provided
by the new implementation.
