[jira] Commented: (OPENJPA-862) Wrong id-parameter used for prepared statement when fetching a collection

["Arne Limburg (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENJPA-862?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12664876#action_12664876 ] 

Arne Limburg commented on OPENJPA-862:
--------------------------------------

When analyzing the executed sql of the test-case, I recognized that OpenJPA uses the wrong Pet-ID during selection of the visits for the second pet. It uses the ID of the first pet instead.

>From this observation I guess this is a caching problem. As a new entity-manager is used for every query (doing this within one entity-manager seems to work fine) the caching problem must be somewhere in the entity-manager-factory.

> When fetching a collection that is a property of an entity that was fetched through a collection, too, under some (reproducable) circumstances the collection is empty instead of filled with the correct entities.
