Hallo again!
I have been reading iText in Action, searching for XFA forms.
In 15.5 Summary says:
<<
For the time being, there is only limited support
for forms created with Adobe Designer (XFA forms).
>>
So, after reading this and your answer a question comes to me:
If I am creating a template PDF with Forms (namely XFA), why
iText has access to the form and can iterate it through the AcroFields?
Thank you in advance!

AFAIK there is no such thing as "leading" when talking about AcroFields.
I guess you meant to say XFA Fields.

You're probably editing an XFA form.

iText only fills AcroFields, it doesn't look at the XFA of the form.

I'm 99% sure your interpretation is wrong.

Er... OK. Can you tell me what this has to do with AcroFields?
(12.7.4.3 of ISO-32000-1).

iText doesn't have to interpret anything!
iText has no problem whatsoever setting the leading.

Indeed: you can't set the leading in a Text field of an AcroForm.
See 12.7.4.3 of ISO-32000-1.

I think you're mixing XFA and AcroForm technology
