[jboss-jira] [JBoss JIRA] Commented: (AS7-789) JPA subsystem: empty default DS

[Heiko Rupp (JIRA)]

    [ https://issues.jboss.org/browse/AS7-789?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12602276#comment-12602276 ] 

Heiko Rupp commented on AS7-789:
--------------------------------

I don't know which default is right. But "" means "nothing set" which contradicts the "required=true" from the description. 

I'd rather see required=> false and default-datasource => undefined / null

> But reading the resource shows an empty value
> This looks wrong, as an empty value is for sure no valid data source name.
