Subject [jira] Commented: (OPENJPA-1843) error in subquery sum is null
Date Wed, 20 Oct 2010 13:37:23 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1843?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12922956#action_12922956
] 

Andre commented on OPENJPA-1843:
--------------------------------

i found a workaround for this issue, by replacing [(select sum(cogsd.quantity) from id.costOfGoodsSoldDetails
cogsd) is null] with [id.costOfGoodsSoldDetails is empty]

But I think it should be allowed

> It worked on Hibernate, i tried replacing is null with '= 0' and its fine but dunno whether
the result is correct or not. Because OpenJPA do not support writing to embbeddables i have
to rewrite some of my code 1st in order to test.
