If you add form fields and give them a name, Foxit assigns an object name but rather than generate a unique string in the normal way, it seems to just add a repeated sequence of 0123456789 to each new object. The first form fields are named:
Helveia01
Helveia012
Helveia0123
Helveia01234
Helveia012345
Helveia0123456
etc
If you add 100+ form fields you end up with object names like this
Helveia0123456789012345678901234567890123456789012 34567890123456789012345678901234567890123456789012 34567890123456789012345678901234567890123456789012 34567890123456789012345678901234567890123456789012 34567890123456789012345678901234567890123456789012 34567890123456789012345678901234567890123456789012 34567890123456789012345678901234567890123456789012 345

If you use a different editor, e.g. the free editor PDFescape, it sensibly names its form fields like this: untitled1, untitled2 etc
