To attach a filled copy of your form to an email you have to add usage Rights to the form first.
You can add those rights with Acrobat XI under File > Save As Other > Reader Extended PDF > Enable More Tools.
You can add those rights with Acrobat X (mac) under File > Save As Other > Reader Extended PDF > Enable Adittional features
Of course this is ridiculous....
Can anyone tell me how i do this in ES4???
Your answer is correct, unless you have the LiveCycle Server Reader Extensions module, then it can be automated.
var SbjtStr = "Property file for " + Page1.BC.rawValue; (Page1.BC.rawValue is a field in my PDF form)
var bdymsg = "The attached property form (" + Page1.BC.rawValue + ") is sent for your disposition.";
event.target.mailDoc(false, "Fb@whateverdomain", "", "", SbjtStr, bdymsg);
