[JBoss JIRA] Created: (JBMESSAGING-604) Duplicate message detection
by Tim Fox (JIRA)
Duplicate message detection
---------------------------
Key: JBMESSAGING-604
URL: http://jira.jboss.com/jira/browse/JBMESSAGING-604
Project: JBoss Messaging
Issue Type: Feature Request
Reporter: Tim Fox
Assigned To: Tim Fox
Fix For: 1.2.1
Whereas JMS requires once and only once *delivery* of messages, there are no such guarantees when sending messages to a queue/durable sub.
This can result in duplicate messages existing in a queue or durable sub.
For some clients this is unacceptable, so we should implement a feature which alerts to the presence of duplicates.
This can be done by keeping a persistent cache of message (or transaction) id on the server. Entries should time out after a period of time.
This will not remove duplicates 100% of the time since we cannot cache the previous values of id for ever, but only for a window.

[JBoss JIRA] Created: (JBPORTAL-1302) supported-window-states ignored ? no limitation to normal window only.

supported-window-states ignored ? no limitation to normal window only.
----------------------------------------------------------------------
Key: JBPORTAL-1302
URL: http://jira.jboss.com/jira/browse/JBPORTAL-1302
Project: JBoss Portal
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Portal Core
Affects Versions: 2.4.1 Final
Environment: portal 2.4.1
Reporter: Antoine Herzog
Assigned To: Julien Viet
In the -object.xml file, remove all window-state elements, but the normal one.
<supported-window-states>
<window-state>normal</window-state>
<!--
<window-state>minimized</window-state>
<window-state>maximized</window-state>
-->
</supported-window-states>
It does not change anything
The min/max icons are still displayed. .
And you can still ask for the maximized or minimized state.
no exception, the portal still works as usual (with the "classic" all three states enabled).
Is it the portal core that should prevent to use these states, if not enabled ?
Or the layout strategy and rendering that should not show the icons ?
(but then, the portal should warn if we type an url that ask a state that is disabled... even it is not by clicking in the window icon).

[JBoss JIRA] Created: (HIBERNATE-50) Embedded Objects get set to null if all its members are null

Embedded Objects get set to null if all its members are null
------------------------------------------------------------
Key: HIBERNATE-50
URL: http://jira.jboss.com/jira/browse/HIBERNATE-50
Project: Hibernate
Issue Type: Bug
Environment: WinXP SP2, JBoss 4.0.4 GA as well as JBoss 4.0.5 GA, installation profile ejb3
Reporter: milan w?lke
Assigned To: Steve Ebersole
When having an embedded object only containing members of non-simple-types (e.g. String) and fetching it with the entity manager the following happens:
If all columns, the embedded objects values are based on, are null the embedded object itself is set to null even if a non-arg-constructor set it to a non-null value before. A valid workaround is to include a member of a simple-type (e.g. int) in the embedded object. Doing this not all the values can be set to null, which results in not setting the embedded object itself to null, too.
