[JBoss Seam] - Re: how can I do optimistic locking with crud framework?

by cja987

I was going by the description of page actions in the seam docs, section 3.1.1 anonymous wrote : | The page action method can return a JSF outcome. If the outcome is non-null, Seam will delegate to the defined JSF navigation rules and a different view may end up being rendered. | I took that to mean that a null outcome meant that it would proceed to the "default" view (the one it would land on without a page action). At any rate, using the propagation parameter looks like a much cleaner way of doing it than blank page actions (though it's usually not a bad place to stick application-level audit log messages). Thanks for pointing it out (and for putting up with my endless questions). You rock my small self-centered universe :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3979539#3979539 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3979539

Ah, I forgot to add the exception handling I meant to add :-) I'll do that now. Thanks for making me look into this stuff. Its good to have someone validate the design and code.

anonymous wrote : /** | * An empty outcome list is interpreted to mean any | * outcome except for the null (redisplay) outcome. | */ | String[] ifOutcome() default {}; | All actions are allowed to return void. And Seam treats void differently to null. Null means "problem with input, redisplay page".

Aha, that did it, and I get ... yay, an HTTP 500 .. but the right error on the console. I guess dealing gracefully with the exception means catching it in update() and company. Figuring out how to present a UI to merge changes should be an interesting project. I can't see anything in @Begin's javadoc that tells me about return values, and I assumed page actions had to return either null to proceed to the given view-id, or optionally return a new viewid. Should I should use s:commandLink if I need to defer to a page action instead? I'll eventually move my complex navigation requirements into jbpm, but it's nice to be able to hack it out with actions first.

I have just tested this and it all works. All I did was: (1) Added a version attribute (2) set scope="conversation" on contactHome (actually I will make this the default scope for a Home) (3) put propagation="begin" on the Edit link.

Actually change it to: @Begin | public void beginEdit() { | log.info("Conversation begun by beginEdit()"); | } (This is more elegant.)

[Management, JMX/JBoss] - Re: deploying mbean in ear

by genman

I've used application.xml typically for .sar files. If you have a jboss-service.xml, you must use a .sar. MBeans can be deployed in other ways (programmatically).

Ahah. Read the JavaDoc for @Begin! And then change: @Begin | public String beginEdit() { | log.info("Conversation begun by beginEdit()"); | return null; | } To: @Begin | public String beginEdit() { | log.info("Conversation begun by beginEdit()"); | return "success"; | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3979531#3979531 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3979531

16:32:06,876 INFO [ContactAction] Conversation begun by beginEdit() | 16:32:06,876 INFO [ContactAction] Conversation begun by beginEdit() I don't see any log message from ConversationInterceptor saying "Beginning long-running conversation", so apparently Seam is definitely not beginning the conversation. What does the beginEdit() method look like?
