[JBoss Seam] - Re: Beginning conversations in @Factory methods

by iradix

Ok Gavin, let me try to explain. I have a page that outputs a DataTable of objects. A user can click on an object's name to select it and bring up an update form or use a button below the list to bring up a form for new object creation. When either of these forms is successfully submitted, the user is returned to the page with the DataTable I want to set the conversation that the @DataModel is outjected into as long running so that when the postback occurs for a selection and my @DataModelSelection is injected it will be sure to come from the same @DataModel displayed to the user. When a new object is created, I want to end the conversation so that the @DataModel, which was retrieved using a now stale query and any state associated with it is dropped before the page with the DataTable is redisplayed. So therein lies my problem. If I begin the conversation from the page containing the DataTable and the conversation is ended by an action method that redisplays that page, the conversation will always be restarted, even after issuing a redirect. Make sense? I'm not married to doing things this way, but it's the best I've come up with, so if it can be done differently please point me in the right direction. -Dave View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3957488#3957488 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3957488

[Clustering/JBoss] - Re: New to JBoss Clustering? Please read before you post.

Looks like a temporary problem with the JBoss wiki. I tried various pages and they all failed with the same error.

[JBoss jBPM] - Re: Assigning task instances to logical group

by kukeltje

Simon, AFAIK YUC ;-) A logical group should be possible to afaik, and I hoped it would already work. I did not test it (will do now, but against 3.2-head) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3957483#3957483 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3957483

anonymous wrote : Yes, but if it's in PAGE scope then on 'postback' the datamodel will be available through EL so won't be recreated. Your scenario is a big reason for PAGE scope :) Good point, I wasn't thinking about how page scope worked. Unfortunately, I have tried this in the past and it adds another big problem.... serializing/reconstituting data. Since my lists consist of attached Entity Beans this is problematic. anonymous wrote : A page action would work as well I think. Remember you can disable conversation propogation for actions and therefore @Begin would start a new conversation. This is equivalent to to your 'stripping the conversation Id'. Disabling propogation sounds perfect.... but how do you do it?

Conversation.leave() will leave the current conversation in an orphaned state though. You probably don't want that.

[JBoss jBPM] - Re: async event execution

by KrisHuggins2k6

Hello, The user guide has a TBD for the "JMS for asynchronous messaging" section. I am looking for more information about how to configure/deploy a jBPM process so it will run asynchronously with JMS or MDB. I'm guessing you need to configure which queue is used when you signal an async node and I'm guessing you need some consumer of the queue to continue the bpm instance. Can someone point me to any documentation, examples & sample code pertaining to this. Any help would be appreciated and I will try to help fill in the TBD section of the documentation.

Well, one way is to remove the RedirectFilter. Other than that, you would have to show me a really compelling usecase for why you need some extra functionality to disable conversation-propagation-over-redirect on a per-request basis. You havn't really described your usecase yet.

I actually looked into that and didn't see anything that jumped out at me. I suppose Conversation.leave() would probably be my best bet. If that unassociates the request from the current conversation then maybe the conversationId won't be added to the redirect. I'll give it a shot.
