Hy, We are getting DummyTransactionExceptions when we are invalidating a session when a non-transient conversation is still open. I just give in the forum a complete guide how to reproduce our problem. Maybe somebody has time to look on it: https://developer.jboss.org/message/909561#909561 Here the resume of the forum: I just tried out with https://ci.jboss.org/hudson/job/WildFly-latest-master/1470/ We are getting the same exception DummyTransactionException We are working in the "full-ha" profile. What we are to reproduce the problem:. - downloading WildFly-latest-master #1470 [Jenkins] - added an management user for the console with "add-user.bat" - changing in %JBOSS_HOME%\domain\configuration\domain.xml the "cluster-password" to a real password - starting up with "domain.bat" and loading the console ( http://localhost:9990) - changed the "main-server-group" to "full-ha" profile with "full-ha-sockets" binding - restarted the WildFly support to get it running in "full-ha" - deplayed the convTest.war (latest version with sources is attached in the forum thread) to the main-server-group and enabled it - doing the test: - opening http://localhost:8080/convTest/step1.jsf - starting a conversation by clicking on "startConversation" button - clicking the "logout" button to invalidate the session => DummyTransactionException What are we doing wrong? Thanks. Tom
