Guess I didn't step away enough to have it make sense to anyone else....

That said, here's some code:

sub cgiapp_prerun {

   my $self = shift;

   my $dbh     = $self->{DBH} = $self->param('DBH');

   ### let's check for storage;

   my $previousClass = $self->query->param('this');

   my $className = "DataClasses::${previousClass}";

   if ( $className->SUPER::can( 'new' ) 
          and $className->SUPER::can( 'store') ) {
      my $object = $className->new( 
           DBH => $dbh, REQUEST => $request );

      ## the needStorage method allows us to 
      ## have multiple "screens" using the same class 
      ## where not all of them store in the DB

      $object->store() if $object->needStorage();
      }
   }

}

and the store() method ...

sub store {

    my ( $self, %params )_ = @_;

    ### if insert ... 

    $self->query->param( -name => 'whatever', -value => '123');
    $self->param( 'whatever', '123' );

    return 1;
}

both methods of stashing the value until the runmode is executed failed. as i've understood the calling stack:

CGI::App->new() -> prerun -> setup -> "runmode" -> teardown

so i don't see how something set in one mode wouldn't carry into another, because it's the same "run cycle".

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
