Well, gnarly is a pretty subjective term .. you might save some typing by...

my (%org, %group);
@org{qw/id name/}   = @hashref{qw/org_id org_name/};
@group{qw/id name/} = @hashref{qw/group_id group_name/};

slashDisplay( 'group_edit', {
      org => \%org ,
      group => \%group
    });
[download]

You might extend that further and replace those {qw/in name/} parts with a predefined array like...

@slash_org_fields=qw/id name/;
@db_org_fields=qw/org_id org_name/;
# Then just use them in place
@org{@slash_org_fields} = @hashref{@db_org_fields};
[download]

Which may or may not present you with greater gnarlyness. I can see the advantages of filling those two temporary hashes together, rather than in the call to slashDisplay()

If I missed the point I apologise - there's a war on you know

I can't believe it's not psellchecked
