Jo Desmet created OWB-1246:
------------------------------
Summary: CDI Event are not observed across SessionScoped beans
Key: OWB-1246
URL: https://issues.apache.org/jira/browse/OWB-1246
Project: OpenWebBeans
Issue Type: Bug
Components: Core, Events
Affects Versions: 1.7.3
Reporter: Jo Desmet
I have a simple setup with just one single Session that backs a JSF xhtml file.
Within that I fire an event, expeting that both the same session, and any other
session will receive the event on submitting.
However, oddly enough, I can see that during the firing of the event, only the
current session receives it, not any other sessions. I am making sure I have
two different sessions by using two different browsers (Safari and Firefox in
this case).
