[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-4454) HibernatePersistenceProvider.init() and PersistenceProvider.init() not executing

[Flavio Costa (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBSEAM-4454?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12495615#action_12495615 ] 

Flavio Costa commented on JBSEAM-4454:
--------------------------------------

I came across the same bug and was introduced due to another bug here: JBSEAM-4093. / r10535.

The WILDCARD_AS_COUNT_QUERY_SUBJECT really stopped working, using Hibernate does not make a difference, because, like Arsen said, the init() method is never called.

My workaround was to create a component with the same name, the "correct" annotation (javax.annotation.PostConstruct) and a higher precedence.

Solutions are reverting revision 10535 (breaking Websphere), advise Websphere users to drop the needed jars with the correct annotations or create a different component that only gets installed when Websphere is detected (worst solution imho).

> Method org.jboss.seam.persistence.PersistenceProvider.init() (including its subclass' method HibernatePersistenceProvider.init()) never gets executed, because it is annotated with @org.jboss.seam.annotations.intercept.PostConstruct instead of @javax.ejb.PostConstruct.
> BTW, this is the root cause why EntityQuery breaks on MySQL when counts entities with composite keys. The method EntityQuery.validate() should setUseWildcardAsCountQuerySubject according to the HibernatePersistenceProvider.supportsFeature(Feature.WILDCARD_AS_COUNT_QUERY_SUBJECT), but the latter always returns false, because HibernatePersistenceProvider.init() that sets the feature flag is never executed.
