Subject [jira] Resolved: (SHALE-360) NPE in shale on GlassFish
Date Fri, 13 Apr 2007 00:30:52 GMT

     [ https://issues.apache.org/struts/browse/SHALE-360?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Craig McClanahan resolved SHALE-360.
------------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: TBD)
                   1.1.0-SNAPSHOT

Added a test such that Shale Remoting will not try to serve resources if someone else has
already completed the response for the current request.  Thanks to Ken Paulsen for the patch
(and the nag to actually get this integrated into the code).

> The following are the stack traces I received.  It seemed to be intermittent.  I think
another bug occurred in Dynamic Faces related to GlassFish restoring session state across
server restarts.  After deserialization, transient variables were not restored... I don't
know if something similar is happenning here, but could be.

> I had accidentally missed the Dynamic Faces init parameter... I thought it was related
to that (note standard lifecycle above).  But after installing the init-param, clearing the
generated directory in GF, and restarting the whole server... I still had an exception from
shale:

> I had it working at one point, I don't know if I did something to break it or if it's
intermittent.  It might not be shale's fault, it may be Dynamic Faces or the app server which
has an error message on startup w/ the init-parm for Dynamic Faces in place:
