thanks. .No the file names match..
That is how the code looks..

VS::Payload
has 'obj_templates', is => 'rw', isa => 'HashRef';

VS::Payload::Postal
has '+obj_templates', is => 'rw',  default => sub{{
....
}};
[download]

It works if I change it to this :

VS::Payload
#has 'obj_templates', is => 'rw', isa => 'HashRef';

VS::Payload::Postal
has 'obj_templates', is => 'rw',  default => sub{{
....
}};
[download]

i.e. it behaves as if I have not declared anything in the parent class.
