Bug in write_fillable_pdf in fillpdfs.py

[jbergma1]

Hi,

starting on line 207, the code currently reads:

                if target and annotation[SUBTYPE_KEY] == WIDGET_SUBTYPE_KEY:
                    key = target[ANNOT_FIELD_KEY][1:-1] # Remove parentheses
                    target_aux = target
                    while target_aux['/Parent']:
                        key = target['/Parent'][ANNOT_FIELD_KEY][1:-1] + '.' + key
                        target_aux = target_aux['/Parent']

Line 211 should be:

key = target_aux['/Parent'][ANNOT_FIELD_KEY][1:-1] + '.' + key

As currently implemented, the code will fail to find fields in the corresponding data_dict if their parents have parents (no proper loop up the ladder of parents).

Apart from that, thank you for your very helpful library!

Kind regards,
Johannes Bergmann
