Documentation fixes w.r.t. events
----------------------------------
Key: JBRULES-2785
URL: https://jira.jboss.org/browse/JBRULES-2785
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-docs
Affects Versions: 5.1.1.FINAL
Reporter: Wolfgang Laun
Assignee: Mark Proctor
Priority: Critical
Fix For: 5.2.0.M1
Correct the documentation:
(1) Explicit expiry time by @expires() in declare has precedence over implicit, dervide from rules. (Critical, because right now is documented the other way round.)
(2) Document that declare without any fields must refer to an existing, imported type.
(3) Document the semantics of timer, and that timer() can only be used in a STREAM session. Also, document that "int:" (as in "timer(int: 0 1m)") is optional.
(4) Make it clear that window:length( N ) is also satisfied if there are less than N events.

Drools: Unable to load session snapshot
---------------------------------------
Key: JBRULES-2681
URL: https://jira.jboss.org/browse/JBRULES-2681
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 5.1.0.FINAL
Environment: Windows Server, SQL Server 2005, Tomcat 5.5, Hibernate, Bitronix
Reporter: Gustavo Tenrreiro
Assignee: Mark Proctor
After an event is processed the session fails to load using JPA persistence.
I ve attached a test case.
It uses a Drools flow file, and a drl file. Both very simple..
The flow file has a "Start" then an action that prints a message to the console, then "End"
The Drl has one rule that processes an event:
import com.kgcontrols.services.company.standardsRequests.workflow.events.VoteCreatedEvent
declare VoteCreatedEvent
@role(event)
end
rule "testEvents"
when
VoteCreatedEvent() from entry-point "VoteCreatedStream"
then
System.out.println("--------------------------- YEAH the event got here");
end
I can see the "YEAH the event go here" on the console so I know the rule fired. But after that, if I try to load the session from the database I get:

[JBoss JIRA] Created: (JBAS-8966) Seam 2 Reexplode causes full undeploy + deploy on AS6
by Cody Lerum (JIRA)
Seam 2 Reexplode causes full undeploy + deploy on AS6
-----------------------------------------------------
Key: JBAS-8966
URL: https://issues.jboss.org/browse/JBAS-8966
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 6.0.0.Final
Environment: JBoss AS 6 Final, Seam 2.2.1
Reporter: Cody Lerum
After upgrading an existing seam 2 project which runs on AS 4.2.3 to run on AS 6 I'm seeing an issue where if I run an reexplode from the seam-gen ant build the application server does a full undeploy and then deploy of the app. This kills any development as I should be able to edit an jsf xhtml page and have that reflected immediately without having to redeploy.
Appears the redeploy scanner is too aggressive or seam-gen is copying over something that worked for reexplode in AS4 but not in AS6
