Add Subform dynamically,on click of Button, in Interactive form generated by Adobe Document Services

Question

HI,
I have an XDP file designed by Adobe Designer 7.1 with the following hierarchy of elements:
-form1(root)
--Button
--tmpForm (subform - Repeat subform for each data entry )
---ST (Text)
Now, this XDP file generates an Interactive PDF form with Reader Rights enabled by the Adobe Document Services.
On click of button, the following javascript is executed on client side:
var df = _tmpForm.addInstance(1);
df.ST.rawValue = "HI" ;
xfa.host.messageBox( "Instances" + tmpForm.all.length ) ;
On clicking the button, i get the length of the instances of the subform and the size increases on each click, but no element is added "visibly" to the pdf.
But when i try to do the same by saving the XDP file as Dynamic PDF form for Acrobat 8.0,and open it using Adobe Acrobat PRO 8.0, it works fine.
My question is,I s it not possible to add subforms dynamically in PDF's generated by Adobe Document Services with Reader Rights enabled?
Or, is there something that i am missing?
Please guide.
Thanks.
Regards,
Siddhartha

Hi,
you can't change the behavior of the save button in the browser nor in Reader/Acrobat.
You can add a custom button within your form which calls a custom script from a folder level script using the browserForDoc method.
The browseForDoc methos is the only one whcih can change the name in the saveAs dialog.
Here's an example., you can run from Acrobat console.
You need to combine it with the solution from the other thread to make it work with your form.

var oRetn = app.browseForDoc({
    bSave: true,
    cFilenameInit: "MyForm.pdf",
    cFSInit: "",
if (typeof oRetn !== "undefined") {
    this.saveAs({
        cFS: oRetn.cFS,
        cPath: oRetn.cPath,
        bPromptToOverwrite: false
