5.80 problem with Catalyst::Model::DBIC::Schema

So, I just tested 5.7099_02 to great success (bravo!) so I decided to
try 5.80 too.

When using SVN rev 8136, I get the error
"->config->{schema_class} must be defined for this model"
I am indeed setting that field (following the instructions in
Catalyst::Model::DBIC::Schema 0.20 to the letter) but it looks like
the schema_class is not getting propagated from the config to the
Catalyst::Model::DBIC::Schema instance via Catalyst::Component::new.

Is this a known problem? Do I need any blead packages other than
Catalyst::Runtime for a proper test?

Chris

I haven't looked at this specific issue, but I'd be prepared to bet
it's a known issue, which I have looked into.

http://dev.catalyst.perl.org/repos/Catalyst/Catalyst-Runtime/5.80/
trunk/lib/Catalyst/Model.pm

See the commented out #__PACKAGE__->meta->make_immutable();

(and the comment below it) - that's the known bug.. You'll *also*
notice that this statement is replicated at the bottom of the file,
not commented out (which is what causes your issues).

There *is* a failing test in Moose for this issue:

http://code2.0beta.co.uk/moose/svn/Moose/trunk/t/600_todo_tests/
003_immutable_n_around.t

However it'd be good if we could just comment out the make_immutable
lines in 5.80 trunk in the short term until this actually gets fixed,
as I'm also chomping at the bit to start testing Catamoose.. Having
said that, I've been getting round to writing a test in Catalyst for
this issue for weeks, so my grumbles about it not working (when
Catalyst doesn't have failing tests) can at best be considered
bikeshedding at this point..

Cheers
t0m

FYI, this issue has now been fixed.

Would be grateful if you could retest, and let us know if this fixes
the problem that you were seeing.

Yep, that error is gone (tested 8171). The next error I see is:

[error] Caught exception in engine "Can't use an undefined value as
an ARRAY reference at /Users/chris/Work/Catalyst/Catalyst-Runtime/
5.80/trunk/lib/Catalyst.pm line 1244."

where line 1244 is:
push( @{ $c->stack }, $code );
and "stack" comes from
has stack => (is => 'rw', default => sub { [] });
That looks pretty straightforward...

Email me off-list if I can provide any more helpful information about
my environment.

Chris

That's ... fucking odd.

Could you make sure you have latest of everything matching qr/^Moose/
and if it persists see if you can post a small example app that explodes
with this error?
