hi, I try to select group on page
var doc = app.activeDocument;
var myModul = doc.groups.item("modul");
//var myModul = doc.groups[0];
//$.writeln("ID: "+myModul.id);
$.writeln("Constructor: "+myModul.constructor.name);
//$.writeln("typ: "+typeof(myModul));
app.select(myModul);
Why this doesn't work 
?
