PDF/A's Checkbox - iText 2.1.7

I need to print a PDF/A document with my Java App, which implements iText 2.1.7. When I use a PDF Templates, my app works fine and print the checkbox checked if they satisfy the conditions.

But, when I use PDF/A Templates, my app doesn't fill these checkbox, but they receive the values correctly.

Can anyone help me? I dont know if this problem is in the template or in the code.

Can you describe in more detail what you are doing?

thesis I: If you have a (non PDF/A) PDF with form fields and then you programmatically change a checkbox value with iText then the change is visible in the PDF (e.g. you can see it in adobe reader and on printed paper) Correct?

thesis II: If you have a PDF/A compliant PDF and change the value of a checkbox then the change is not visible in the PDF (neither in adobe reader nor on printed paper) Correct?

In the PDF format you need to differentiate between the appearance of a field and the (data) value of a field. Normally PDF/A documents are made for long term archiving and not to change values. If you still do that you need to ensure that you also update the appearance of a form field.

Try to update the appearance of the field you change (after you set the new value). You can do that with the following method:

AcroField fields;
boolean success = fields.regenerateField(String yourCheckboxFieldName);
