, and when I run it, I get the following message error:
I know the problem is that function should have been called with an object from Param, but I was expecting that the constructor Param(int , int) would do the job.
What is wrong with my assumption, and how could I fix this problem?
thank you in advance!!

jifty::param
Jifty::Param(3pm) User Contributed Perl Documentation Jifty::Param(3pm)NAME
Jifty::Param - Parameters for Jifty actions
DESCRIPTION
Describes a parameter to a "Jifty::Action" object. Do not construct this by hand -- use Jifty::Param::Schema in the action package to
declare parameters instead.
accessors
Although this class is not derived from Jifty::Web::Form::Field, it does share the accessors from it; see Jifty::Web::Form::Field, for the
list of possible keys that each parameter can have.
In addition to the list there, you may use these additional keys:
constructor
A boolean which, if set, indicates that the argument must be present in the "arguments" passed to create the action, rather than being
expected to be set later.
Defaults to false.
valid_values
An array reference. Each element should be either:
o A hash reference with a "display" field for the string to display for the value, and a "value" field for the value to actually send
to the server.
o A hash reference with a "collection" field containing a Jifty::Collection, and "display_from" and "value_from" fields containing
the names of methods to call on each record in the collection to get "display" and "value".
o A simple string, which is treated as both "display" and "value".
available_values
Just like valid_values, but represents the list of suggested values, instead of the list of acceptable values.
sort_order
An integer of how the parameter sorts relative to other parameters. This is usually implicitly generated by its declaration order.
new
Creates a new Jifty::Param object. Note that unlike Jifty::Web::Form::Field, the object is never magically reblessed into a subclass.
Should only be called implicitly from a Jifty::Param::Schema declaration.
