[JBoss Seam] - Re: Named conversation and new instance redirected to Home?

by enda

So imagine a scenario that you have one entity lets say people. You will provide a table of all people. You can edit people and add new people. Now you want to use jPDL and natural conversations (mix jPDL and pages.xml because jPDL does not offer you to specify conversation name). (note: I used to use deprecated method annotation for begin(id="foo.id")) You start a conversation whenever you click on a person from table or a new person button. You also want to join conversations with the same id. Scenerio 1: (problem join) you will click on person and will start conversation. In pages.xml is defined | <conversation name="personHome" | parameter-name="personName" | parameter-value="person-#{empty person.id ? 'new' : person.username}"/> | | <page view-id="/private/search/people/personHomeView.xhtml" | conversation="personHome" | conversation-required="true" | no-conversation-view-id="/private/home.xhtml"/> | so your natural conversation has id==person.id Problem 1. raises when you want to join conversations with the same name (same person). Because the behavior is: start conversation, redirect to the page personHomeView.xhtml and name the conversation id==person.id as defined in pages.xml. The thing is that <conversation name="personHome" | parameter-name="id" | parameter-value="#{empty person.id ? 'new' : person.id}"/> should have parameter join. You cannot use annotation (join) on your selection method in session bean. Because at that time the new conversation has id=random and named id is made later from pages.xml. The main point is that I can use join at the time when I do not know which object is selected! so conversation has id=random which is renamed later in pages.xml, but if such a conversation id already exists it throws an error instead of joining. Note: this does not help because you do not know person instance at the time (otherwise as SeamBay) <h:commandButton ..action="select(person)" > | <s:conversationName value=".."/> | .. | (SeamBay does not show this, it has passing id via get, but it seems like very un-maintainable and hacked solution) Scenerio 2: (problem conversation rename) Problem 2: you want to create a new person and then redirect to person home (jPDL). <page view-id="/private/search/people/personHomeEdit.xhtml" | conversation="personHome" | conversation-required="true" | no-conversation-view-id="/private/home.xhtml"/> So you click on the button and call method that creates new object Person and starts new conversation. Then after method is done it redirects you from table to personHomeEdit and conversation is named id=new(note conversation id definition). Ok you fill out the form and saves the person. Then you are redirected to a page personHome. BUT now the Person instance has id now!!! so definition of conversationName evaluates it as conversation id=person.id and not id=new. personHome now expects conversation name id=person.id but such a conversation does not exist! so I am redirect to a default page. (Now I can manually check it in my method and in case of join redirect, but it is hack too and seam should have something better) What about make an clear example in your documnetation pages doing exactly this: one entity and two pages (Home and HomeEdit). You will use natural conversations (No hack as in SeamBay or maybe I did not look at it carefully). You can edit table entry(redirect to Home and then to HomeEdit and then HomeEdit) and create new (redirect to HomeEdit then to Home) Thanks for answer Tomas ;D View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125965#4125965 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4125965

What's the problem of using the default constructor? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125964#4125964 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4125964

[JBoss Seam] - Re: s:formattedText fails with dynamic content being null

by pete.muir＠jboss.org

Not reported afaik. Please file an issue and we'll see if we can get rid of the spurious error message. In generate SeamText is quite picky about syntax.

[JBoss Seam] - Re: the best way to maintain search conditions?

by pete.muir＠jboss.org

You probably want to use session scope to store the conditions rather than conversation if you want to want them to be remembered whilst the user is on the site.

[JBoss Seam] - Re: Standard JAAS security domain not getting picked up

by shane.bryzak＠jboss.com

I just tried this with the jmx-console config and was able to login successfully. On a side note, jaas-config-name and authenticate-method are mutually exclusive, if you specify an alternate jaas config then you don't need to write your own authenticator. I suggest that you set a breakpoint in Identity.getLoginContext() to see why the correct LoginContext isn't being returned.

[JBoss Seam] - Re: Unwanted datamodel update on action cancel

by pete.muir＠jboss.org

Use manual flushmode and use the none conversation propagation. I wouldn't do what javichi_fer suggests -thats pretty ugly.

[JBoss Seam] - Re: jbpm timer transaction issues

by pete.muir＠jboss.org

I don't really know what the problem is here. I'm a bit overloaded atm. But if you can create a JIRA issue, and attach a simple example to reproduce with steps, then hopefully someone can take a look soon. With the first exception - what is the NPE from Hibernate about? You might want to cross post to the jbpm forum, as I'm not sure exactly what is Seam and what is JBPM here.

[JBoss Seam] - Re: EVENT_LOGIN_SUCCESSFUL handled twice

by joeyxxx

Thanks Shane. I'm a bit confused here. Why is my overridden method invoked twice? If the addLogin.. in the super class is registered in addition to my overridden addLogin.., I would expect one invocation in the super class and another in the sub class. I'm I missing something?

Put a breakpoint in SeamLoginModule.login and see why the authenticate method isn't being used. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125956#4125956 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4125956

[JBoss Seam] - Re: Seam & JBPM (WebConsole)

by brombie

There's a book published by Apress called Practical Seam Project (or something like that) that has more about Seam and jbpm integration. For the jbpm console, just find the war file in the jbpm package that you've downloaded and plop/explode it inside your jboss deploy folder. If you're using JBoss 4.2, you'll need to tweak the war file or you'll get errors. See the jbpm wiki for it. What I found work for myself is building it from the code. The jbpm wiki has this covered too.
