[jira] [Commented] (QPID-7221) [Java Broker] On VirtualHost creation ManagedAttribute queue.deadLetterQueueEnabled should be initialised by context variable instead of referencing it

    [ https://issues.apache.org/jira/browse/QPID-7221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15322303#comment-15322303 ] 

Keith Wall commented on QPID-7221:
----------------------------------

Add an parameter to ManagedAttribute to indicated to the ACO framework that the default value should be materialised as the child is created.

> Currently, {{VirtualHost._queue_deadLetterQueueEnabled}} defaults to {{$&#123;queue.deadLetterQueueEnabled&#125;}}.
> This context variable is not materialised when the VirtualHost is instantiated. This can cause surprising behaviour when either the context var changes or a VH configuration is migrated to a different broker where the context variable might be different.
> In addition the UI does not resolve the context variable leading it to not correctly display the state of the checkbox (QPID-7227).
