Hi,

I may not fully understand your use case, but
typically the stash is used for a particular context,
not as a global thing.

You can alway pass the context to methods that need
it.  I know it seems cumbersome, but the reason is to
make you really think if you need it, the idea being
that you should try to decouple your context as much
as possible.

If you need some global information there are a few
ways I can think of:

1) put it into the configuration file.  This is great
for static stuff, like admin email address, etc.
2) Create a model that provides the information you
need.  If this information is based on the current
context you can inherit from
"Catalyst::Component::ACCEPT_CONTEXT" to build it.
3) Create a base controller with a method that gets
the information you need.  The have the controllers
that need this information inherit from that.

You might get the suggestion to make this a catalyst
plugin, but that's no longer recommended best
practices.  Plugins should be reserved for when you
are trulying enhancing/extending the basic Catalyst
features.

Please share with us the details of the use case and
maybe we can help.
