Can you provide a simplified test case that shows this behaviour, or

That output's being generated by CGI::Application::Dispatch, which is
calling Data::Dumper:Dumper on the $args that are about to be passed
to new().
It'd be interested to fire the server up under the perl debugger,
break at that line, and see what's up with $args.
Hi George,
Well I've managed to narrow it down a bit - the problem was caused by
defining the path/to/templates twice - once in TMPL_PATH => [
$path_to_templates ] in my Dispatch \%args_to_new hashref, and again in
the webapp.cfg tt_config TEMPLATE_OPTIONS. As I can't avoid passing
path/to/cfg in args_to_new, the fix is of course to omit TMPL_PATH.
I suspected this might be the case from the very simple demo app I put
together for you (mailed separately), where I could see that the first
request after server-start generated 2 '/path/to/templates' entries, the
second request generated 4, third request generated 8, then 16, 32, etc.
With my own app, the multiplication came much faster - the first request
generated 8 '/path/to/templates' entries, second generated 64, and I
didn't count the 3rd but would predict it was 512. There's probably a
simple reason for this, but it's not that I've defined path/to/templates
8 times in my App!
However, the curious thing is - afaict, there is only one definition of
path/to/templates in the demo app (and that's in the Dispatcher not the
WebApp), so I've mailed it to you so you can investigate the phenomenon.
Failure to include TMPL_PATH in the demos' Dispatcher is fatal as the
WebApp can't find the templates, confirming that there is only a single
source of templates path info. My guess is that the problem lies in the
definition of TMPL_PATH in args_to_new() in the Dispatcher rather than
in the webapps' config file. I'd also take a guess that it's something
pretty simple to trace if you're handy with perl -d.
