Hi I'm trying to handle a callback filter in a catalyst application.
In my form, I have the following especification:
---
action: /test/foo
indicator: submit
auto_fieldset: 1
elements:
- type: Text
name: user
filters:
- type: Callback
callback: foo::Controller::test::bar
However, Catalyst always dies with the "Can't use string
("foo::Controller::test::bar") as a subroutine ref while "strict
refs" in use".
Can you explain me how can I run a sub of mine to filter an element?
At the moment, callback() only accepts a subref, such as \&foo;
meaning it can't be set in a yaml file.
It would probably be reasonable though, to change it so that if it's
given a string, to call that as a subroutine name.
I "fixed" that by editing Filter/Callback.pm and adding
no strict 'refs'
before the actual call to the sub... I'm not properly sure if this is
a cool hack or not..
