Subject [jira] Updated: (OPENJPA-570) Misleading "Found duplicate query" warning message
Date Tue, 15 Apr 2008 03:03:04 GMT

     [ https://issues.apache.org/jira/browse/OPENJPA-570?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Albert Lee updated OPENJPA-570:
-------------------------------

    Attachment: OPENJPA-570.patch

Model after the AnnotationPersistenceMetaDataParser.parsePackageAnnotations(), an extra test
is performed in parseClassAnnotations() method for the Named*Quer* annotations to see if the
MODE_QUERY has been performed before by examining the meta.getSourceMode() before the actualNamed*Queries()
method is invoked.

This is not a functional but serviceability and performance correction.

Albert Lee.

> Even when unique @NamedQuery is defined in application, the following misleading warning
message (sample) is posted in the log:
>     openjpa.MetaData - Found duplicate query "getEmployeeOrdered" in "class employee.list.Employee".
 Ignoring.
> This message should only be used when duplicated @NamedQuery definitions are found.
> The reason this message is posted is because the same entity is being "parsed" twice,
once from:
