MDB activated too early to use Seam components as a standard EJB
----------------------------------------------------------------
Key: JBSEAM-2286
URL: http://jira.jboss.com/jira/browse/JBSEAM-2286
Project: JBoss Seam
Issue Type: Bug
Affects Versions: 2.0.0.GA
Reporter: Siarhei Dudzin
Priority: Critical
As specified in the forum reference I have an MDB which uses a SLSB (also declared as Seam component) with business logic. If I deploy the application and there are already messages in the queue I get the following exception:
javax.ejb.EJBTransactionRolledbackException: java.lang.IllegalStateException: Attempted to invoke a
Seam component outside the an initialized application
at org.jboss.ejb3.tx.Ejb3TxPolicy.handleInCallerTx(Ejb3TxPolicy.java:87)

at $Proxy111.onMessage(Unknown Source)
Looks like the MDB processing the message before Seam is initialized?
This forces me to undeclare the SLSB as a Seam component and (potentially) duplicate business logic if I want to re-use the same functionality of the SLSB in Seam.
I could use the solution from http://www.jboss.org/?module=bb&op=viewtopic&t=100946 but then it would force me to use vendor-specific API.

6.12.2. Enabling Seam exception handling : web:exception-filter in components.xml
---------------------------------------------------------------------------------
Key: JBSEAM-4693
URL: https://jira.jboss.org/browse/JBSEAM-4693
Project: Seam
Issue Type: Task
Components: Documentation Issues
Reporter: simon lebettre
this does not make sense :
"
6.12.2. Enabling Seam exception handling
To enable Seam's exception handling, we need to make sure we have the master servlet filter declared in web.xml:
"
==> Of course the master filter is in web.xml !
this would be more relevant :
"we need to make sure that <web:exception-filter url-pattern="*.seam" /> is declared in components.xml"
I m not being picky about the doc, it's been 7 months I have a bad user experience or loose some exception feedback because I forgot this line in components.xml !

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-4487) Concurrent requests; one invalidates the session, results in recursive loop of session creation

Concurrent requests; one invalidates the session, results in recursive loop of session creation
-----------------------------------------------------------------------------------------------
Key: JBSEAM-4487
URL: https://jira.jboss.org/jira/browse/JBSEAM-4487
Project: Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.2.0.GA, 2.2.0.CR1, 2.1.2.GA, 2.1.2.CR2, 2.1.2.CR1, 2.1.1.GA
Environment: Jboss 4.2.2 with shipped Tomcat on Linux.
Reporter: dave atkins
I noticed that we had an massive number of sessions on one of our tomcat nodes that hosts our modest Seam app. After some investigation I discovered this in the log
2009-11-25 17:38:02,521 INFO [org.jboss.seam.contexts.Contexts] starting up: org.jboss.seam.web.session 2009-11-25 17:38:02,522 INFO [org.jboss.seam.contexts.Contexts] starting up: org.jboss.seam.security.identity 2009-11-25 17:38:02,522 INFO [org.jboss.seam.contexts.Contexts] starting up: org.jboss.seam.web.session 2009-11-25 17:38:02,522 INFO [org.jboss.seam.contexts.Contexts] starting up: org.jboss.seam.security.identity 2009-11-25 17:38:02,522 INFO [org.jboss.seam.contexts.Contexts] starting up: org.jboss.seam.web.session
This is repeated for thousands of lines. After digging around the seam code I realised that if you have two concurrent requests and one invalidates the session before the other is finished, seam goes into an recursive loop of session creation (normally ended by stack overflow). Here's a stack trace showing two recursions.

This problem is partially documented here - https://jira.jboss.org/jira/browse/JBSEAM-2888, unfortunately this bugfix didn't solve the root cause of the problem.
The problem is caused by the SessionMap used by ServerConversationContext. Internally the session map uses HttpServletRequest.getSession(true) to retrieve the session, which creates a new session if the one defined on the HttpServletRequest is invalid or null. Unfortunately, when the new session is created session listeners are informed before the session has been set on the HttpServletRequest. Seam is one of these session listeners and creates a new Identity on session creation, which in turn accesses the SessionMap, still before the new Session has been set on the request. This leads to an infinite recursive loop.
The SessionMap used is returned by externalContext.getSessionMap(). One solution could be to implement our own SessionMap that doesn't attempt to create a new session if the current session is invalid or null, although I've no idea how this would impact on other Seam code.
The problem is relatively easy to create. In our application we have a search page that can take quite a while to complete a request. If we log out of the application in another tab before the search has completed the problem arises.
We are using seam 2.1.1.GA. I've looked at the source code for the latest release and it appears that the problem will still occur due to use of SessionMap.
Out current workaround is to add a ThreadLocal to Identity.create that counts recursive calls. If more then two recursive calls are detected an IllegalProcessState exception is thrown. This isn't definitely isn't a permanent solution, but stops our server creating 100,000 sessions.

java.lang.IllegalStateException: BaseTransaction.checkTransactionState - thread is already associated with a transaction!
-------------------------------------------------------------------------------------------------------------------------
Key: SEAM-99
URL: https://issues.jboss.org/browse/SEAM-99
Project: Seam 3 Distribution
Issue Type: Bug
Affects Versions: 3.0.0.Final
Environment: JBoss 7
Reporter: Markus Dahm
we sometimes get this exception - especially when clicking fast in the application.
It won't go away until the server is restarted...!
I'm not sure whether this bug is related to AS 7 or Seam...
