Is is possible to validate a form in a workflow?

Question

I have  an .xdp form and .xml file with some data. Using renderPDFForm2 Operation I convert these two files into the pdf document. All this happans in a workflow/process, which is used by some external system. And after convertation a system receives the result pdf document.
So, the question: is it possible to validate pdf document in a workflow? For example, my validation script in a form contains some code for checking if a client age is above 18 y.o. So, if the input data contains client age = 17, i want to return to the system some sort of error, but not the resulting pdf.
An ideal solution which i want to find is some way to validate pdf form without dublicating validation code. Cause i have an idea how to check the age, using variables and expresions in a process. But in that case i'll have this validation both in pdf document (for example, to prevent users from printing not valid pdfs) and in a workflow.

Hi Victoria,
I have a validation script for PDF forms, you can use this script to validate the whole form to verify if any field returns null. This script is only to check if all fields are filled in. There is an exception array which you can insert field's names which you don't want it to be validated. You can then make your own validation for those fields included in the exception array.
So as an example, if your field age is named : txtAge
you would insert the name txtAge in the exception array:
var tabException = new Array("txtAge", "txtAnyOtherField");
var strFirstField = objValidate.getFirstField(form1, tabException);//form1 to be the top most subform or any subform to validate
var boValidate = true;
if (strFirstField != ""){
     boValidate = false;
if (boValidate){
     if (parseInt(txtAge.rawValue) < 18){
          boValidate = false;
          strFirstField = txtAge.somExpression;
     if (boValidate){
          //Any specific validation to be put here before printing
if (!boValidate){
     xfa.host.setFocus(strFirstField);
     xfa.host.messageBox("Error, please make sure data is valid.");
} else{
    xfa.host.print(1, "0", (xfa.host.numPages -1).toString(), 0, 0, 0, 0, 0);
You can use this template form to see how the function works:
Validation / Reset Functions, easy to manipulate and to change Forms!!!!
Hope this helps.
