[JBoss-user] [JBoss Seam] - Re: SeamExtendedManagedPersistencePhaseListener
Well, SEMPPL seems work fine to me in JBoss 4.0.4GA + Seam 20060520 + jsf-facelets 1.1.4. It has still a drawback, anyway: when an exception occurs in a page, it leaks the serving transaction which is left active in the thread and may eventually be propagated to other servlets. For the very same reason, an exception in a page may led to a unusable application: the user often can't just avoid the wrong page and do something else. Do you experience the same?

[JBoss-user] [JBoss Seam] - Re: resume parent conversation in @End method
This is an interesting new feature. Do you think there would be any usefulness in enhancing it (or perhaps extending it) to the case in which one is popping and redirecting from the topmost conversation? I guess it could be usefull in many cases. In example, a logon issued by a login interceptor could start a conversation which, when ended, resumes to the point were it was started. This would get a logon on demand function implementation simpler, in example. I mean, the conversation return point should be saved in the conversation itself, not in its parent conversation. This would allow a non-null return value when ending and redirecting the topmost conversation.

[JBoss-user] [JBoss Seam] - Re: SeamExtendedManagedPersistencePhaseListener
I found a (very) temporary workaround to the transaction-still-there: don't use
the SeamExtendedManagedPersistencePhaseListener.
I had somewhere a servlet filter adding transactional behaviour to http
requests. It basicly wraps a transaction begin/commit around an http request,
rolling the transaction back on exceptions. I just put this servlet on top of
the SeamServlet and used SeamPhaseListener instead of the extended one. It
works more or less (didn't try with jBPM), but please don't ask me exactly why.
Gavin, I see there is a SeamTransactionManagedPersistencePhaseListener, which
sounds close the the temporary kludge I applied. I would like to give it a try,
but it seems to me that's not referenced in any doc. Defining it as a
PhaseListener in my app, I got this:

What about the following? After restarting jboss and the app and accessing this
page from the main one, the page is correctly shown but the request ends with a
RollbackException, which mean someone marked rollback-only the transaction.
Please note that no place in the involved application code deals with marking
the transaction rollback-only. The only place in which I could eventually do it
is in the ImageServlet, but the two pages (the main one and the one for which
I'm reporting this log) does not actually make use of it.

[JBoss-user] [JBoss Seam] - SeamExtendedManagedPersistencePhaseListener
I'm having a bad time with it. I'm developing a webapp in which I have conversations (and plan to use jBPM) and some custom servlet for handling images. The problem is that, sometime, my image servlet throws an exception by which I'm told that a UserTransaction is already active. The image servlet has to access the db (by its own means: no seam or whatever), so it obtains a UserTransaction, and EntityManager and begins a transaction. Using SeamPhaseListener everything was fine, but with SeamExtendedManagedPersistencePhaseListener it seems that transactions are now not committed/rolled-back once opened when a conversation is started. Now, I know that a transaction as well as an EntityManager or Hibernate Session object is something tied to a thread, so I suppose that when my image servlet fails it is because the thread it is running into is the very same hosting a previous seam request. Well, I'm not really shure this is the right seam behaviour, anyway: UserTransaction, EntityManager and Session instances should be closed or (somehow) detached from the thread at the end of a request, isn't it? Did I find something wrong in seam, or it's (again) just me? How I'm supposed to mitigate the two needs (transactions with seam conversations and servlet decoupling)? Regards.

Well, it may be. But why it happens on finalizing a component and not when injecting EMs? Also, if it is a classpath problem, I would expect to see it everytime, not in few, exact conditions. Isn't that there is a classloader problem somewhere? Like, say, the tomcat's thread pool is grown from a different classloader then the one that creates the initial pool. (NOTE NOTE: just guessing). Or... I have this in jboss-app.xml: | jboss-app | loader-repositoryseam.jboss.org:loader=mywebapp/loader-repository | moduleservicelogin-service.xml/service/module | /jboss-app | Is it this the problem?

[JBoss-user] [JBoss Seam] - Re: @In, @Out and @Factory. It's me or...
Almost: splitting the MyClass in two classes, one outjecting idCat and one outjecting currentCategory, as well as emulating the behaviour of @Factory through @Out(s) on getters solved the problem. It is not that elegant, but works. After changes I thought that retrieving idCat in initCurrentCategory() using Component.getInstance(...) could have possibly forced the idCat factory invocation, but I didn't try it. Do you have any suggestion to spare?

[JBoss-user] [JBoss Seam] - @In, @Out and @Factory. It's me or...
Dears,
I have something like this in a Seam component of mines:
| @Name(myComp)
| @Scope(ScopeType.EVENT)
| @Intercept(InterceptionType.ALWAYS)
| public class MyComp {
| @In(create = true)
| private HibernateEntityManager theDatabase;
|
|
| @RequestParameter
| private String p;
|
| @In(create = true) @Out
| private Integer idCat;
|
| @Factory(idCat)
| public void initIdCat()
| { idCat = Integer.valueOf(c); }
|
|
| @In(create = true) @Out
| private Cat currentCategory;
|
| @Factory(currentCategory)
| public void initCurrentCategory() {
| currentCategory =
(Cat)theDatabase.getSession().createCriteria(Cat.class)
| .add(Restrictions.idEq(idCat))
| .uniqueResult();
| }
|
|
| // Etc, etc...
| }
|
Now, when I ask for the idCat value from a JSF page, I get a correct result.
When I attempt from that page to get the value of currentCategory, I get a
NullPointerException in which it is said that idCat in initCurrentCategory() is
null.
Is it a Seam issue or a Giampaolo's one?
Regards,
Giampaolo

Well, context demarcation happens in component code, not in jsf page... However, actually I don't use it at all. I will for some pages, but not yet. @Out with @Factory always works to me when the outjected value is asked by jsf pages. It never works to me when it is used from inside the same component supplying it, as in the example provided.

[JBoss-user] [JBoss Seam] - Re: @In, @Out and @Factory. It's me or...
Ok, my brain was elsewhere while writing my previous post... Now I got your
point.
I think there shouldn't be any difference in grabbing an attr at context or
from component level: after all, in any case there is an underlying faces
context triggering the (in my case cascaded) bijections...
Also, Seam doesn't have to adhere to any (more or less silly) standard, so,
taken I'm not the only dumb here to feel a feature like this useful, I wouldn't
say that we misunderstood the concept of seam component. Maybe that seam
developers relied too much on the example Hotel app?
Also, calling the idCat property means I have to trash the Factory-based
design, which I don't dislike at all. I would need to wrap my attrs within
| if(attr == null) {
| // Build attr
| }
|
| return(attr);
|
constructs. Not a big problem, but... oh my!
There is probably another way to let this work, which is to retrieve the idCat
attribute in initCurrentCategory from a FacesContext. But, again, it's right
few lines above! Why one would need to do that? Anyway, I'm going to try it...

[EMAIL PROTECTED] wrote : Yes, it does seem to fix the bug in all cases. You have to return an outcome and trigger a navigation rule from faces-config.xml. I have this problem, too. But I don't (yet) have any interceptor triggered: I'm actually prototipizing a site and have only navigation links between pages (through h:outputLink). When I click on a link, sometimes I get the _id0 duplicated messages, which gets fixed simply by reloading the page in the browser. I have a two-level template nesting, however, which would cost me a bit to flatten. But I suspect that this may be the cause in my case. Did anybody of you experienced this problem with nested templates? Also, days are passed by the time of the last reply to this issue. So, I would like to know if there had been any advance in definitely fixing it.

However, you were right, Gavin: upgrading the MyFaces core library (api+impl) to the 1.1.3-SNAPSHOT dated march 27, 2006, solved this issue at least for me. To whom it may concern, the MyFaces core's 1.1.3 nightly snapshots may be downloaded from http://cvs.apache.org/builds/myfaces/nightly/. An upgrade of the commons-codec, commons-collections and commons-digester libraries in the jsf-libs directory is also needed, as well as a copy of the commons-lang one, which wasn't needed at all in 1.1.1. These dependency libraries are shipped with the snapshort archive as well.
