Jorge Quiroga commented on TAPESTRY-2055:
-----------------------------------------
After a year. the problem is still there, Is someone working in this
issue?. some of us cannot migrate to Tap5 and this problem is critical and
having an application Server for each tapestry application isn't a real
solution. When 4.1.7 will be released?, some temptative date with this
problem resolved?. thanks.
Problem when running 2+ tapestry web apps in same application server
--------------------------------------------------------------------
Key: TAPESTRY-2055
URL: https://issues.apache.org/jira/browse/TAPESTRY-2055
Project: Tapestry
Issue Type: Bug
Affects Versions: 4.1.3
Environment: JBoss 4.2.x, Tapestry 4.1.3, MySQL5
Reporter: Eduardo Magdalena
Assignee: Jesse Kuhnert
Fix For: 4.1.7
I have an enterprise Java Bean which feeds multiple tapestry apps. I can
open a session on two apps but when I open a second session on one of them
and enter on a page not previously loaded (in the first session) I get:
On browser:
java.lang.NullPointerException

On JBoss Console I get a thousand of stack traces (sometimes infinite),
being the most relevant:

So it fails: Tapestry, Hivemind, OGNL, JavaAssist ...
The only solution I got so far is have a JBoss instance for each
WebApp...
