I have a custom servlet in my application where I'd like the conversation to
span the whole session.
I want all my entities managed for the duration of the http session. I'd use
@PersistenceContext(EXTENDED), but this would only work if I merged all entity
references that I got from other
Sorry, I meant, ScopeType.SESSION instead of STATEFUL

Also, I understand that the SMPC is conversation scoped, but then what should I
use in a Session scoped Session bean where there is no natural conversation
Do you have a @Local or @Remote annotated interface with int getValue(); in
it?

Make sure you have the following in components.xml
component name=org.jboss.seam.ui.EntityConverter
| property name=entityManager#{entityManager}/property
| /component
Incidentally, I think this component should have a lowerCamelCase name
(entityConverter rather than EntityConverter) as
I just recently moved my project to JBoss 4.2.2 from 4.2.0. I've noticed many

Anyone have any ideas / suggestions?

Is my understanding correct:
One should use a SMPC in Seam components that are *not* session beans.
@In EntityManager
I've also noticed that if I find an entity using a EJB PersistenceContext EM,
then I get LazyInitializationExceptions when trying to fetch a property of that
entity in another bean that uses the SMPC EM.
The only way I've found around this is to re-fetch the entity using the current
EM.

I've used the jboss-app.xml from the Registration example. I've since merged

In case this helps someone else...
If I remove jboss-app.xml from app.ear/META-INF/ then the messages.properties
file in each WAR is loaded for the appropriate context.
With jboss-app.xml included, only one of the messages.properties files is
loaded, the others are ignored.
I'm not certain
I have an EAR that contains 2 WARs. I have different messages.properties for
each WAR. I've not been able to get them both to work. The message bundle first

In other words, if I go to localhost:8080/a/ then the messages from

Hi Pete, I'm very grateful for your reply. I've significantly paired down the
jars that I'm packaging:
| asm-2.2.jar
| asm-attrs-1.5.3.jar
| commons-beanutils-1.7.0.jar
| commons-digester-1.8.jar
| commons-el-1.0.jar

How should EARs with multiple WARs be packaged? How'bout if they share the same

After adding a jboss-app.xml file to my ear/META-INF/ dir I've started seeing
the following error when starting jboss 4.2.2:

Pete,
Thanks for the reply. I'm creating a test app now, and will submit it to JIRA.
Is there anything you suggest I try, in order to isolate the issue? I've only
noticed this behavior because the following stopped working:
security:identity authenticate-method=#{authenticator.authenticate} /
Ok, it's starting to make more sense (though the behavior has changed since
since moving to seam 2 from 1.2)
I have several components.xml files, each of which configure the Identity
authenticate-method to use a different auth component method:
a.war:
security:identity
It looks like seam needs to be loaded multiple times - once for each web module
- to configure the built in components differently. I had mostly the same
structure using seam 1.2 and this worked, so I'm not sure what's changed.
If I only have one module then it correctly invokes the

I've filed a JIRA issue:
http://jira.jboss.org/jira/browse/JBSEAM-2523
From what I've found it looks like the Identity component is not scopped to
the appropriate WAR. If you have an EAR with multiple WARs it's not clear
which Identy component (which components.xml configuration) will apply.
I'm in the process of migrating from seam 1.2 to 2.0.1CR1 and I've run into a
problem. My application is packaged as an ear, with multiple web modules (each
with their own components.xml, pages.xml, etc). The java classes used by all
web modules are packaged in a single jar.

Ugly workaround:
Everything works as expected if I:
1) start Jboss as normal
2) undeploy my ear (move it to a temp dir)
3) redeploy it (move it back into the deploy dir)
Note. for this to work I must also package those extra dummy jars (they only
have 1 file - seam.properties).
But, if I just
i had this exact same problem. You can somewhat improve things by adding a
delays or queues as you've done but it is not a good solution as the problem
can still occur - just less frequently, or under more rare circumstances.
This can also occur if a user clicks on an a4j:commandButton too
Don't have any information for you, but I'm also going to be thinking of
clustering shortly and would appreciate any insight.

This problem does not happen on non-conversational pages. I'm hoping there's a

The problem with that approach is that the proper value for requestDelay
