Craig McClanahan commented on SHALE-360:
----------------------------------------
Ken, do you have any concrete reproducible example for this? Without anything
more to go on, it's going to be basically impossible to debug this.
The NPE at line 300 of MappingImpl could happen only if the "mappings" instance
variable had been corrupted. In turn, the only way that can happen is if
someone calls setMappings(null) after the mapping configurations have been
loaded -- the framework's only call to setMappings() is guaranteed to have a
non-null parameter, or an exception would have been thrown. Is there anything
in your code that ever calls this?
By the way, the last stack trace ("Cant create Lifecycle for id:
com.sun.faces.lifecycle.PARTIAL") is definitely not related to Shale.

> Project: Shale
> Issue Type: Bug
> Components: Remoting
> Affects Versions: 1.0.3
> Environment: GlassFish v2 build 28
> Reporter: Ken Paulsen
>
> 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
