Quick PDF explanation.
First, there are two types of forms technologies in PDF, AcroForms and XFA.
Each has a checkbox “type”
Second, each form field “type” in PDF has a set of “appearances” associated
with it – up, down, etc. These can look like ANYTHING YOU WANT.
Third, the values of a checkbox has no explicit meaning. You can call it “On”
or “Fred” - PDF doesn’t care. You simply need to match it up with the
appearances.
For more details – see ISO 32000-1.

Hi,
I have two kinds of Check Boxes in Pdf document.
One check box display X (cross ) sign on click while the others dispaly ✓ (
right sign ).
Itext report both as check boxes as field type. But only the earlier one (
with Cross Sign) are displayed on form as market when i set to 'On'. The others
remain un-checked but when I read the values programmtically using iText they
are also changed to 'On' but not visually.
Any idea,
Regards
Zeeshan
