The default behavior for the FDF Toolkit is to return an FDFErcNoValue for the FDFGetValue when the
field exists but has no value.
Whether or not this is truly an error is debateable. It seems to become an issue in documents
created by Acrobat 5 when optional fields are included in a form with required fields since the
default behavior seems to be to populate the HTTP_FDF_DATA with the results of the FDFNextFieldName
enumerator, which would include the fields which have no value.
This would not be a problem except that the PHP function fdf_get_value() does not specifically test
for the FDFErcNoValue condition but, instead, tests for the more general FDFErcOK. If this value is
not the result of the error code, the system issues warnings (the display of which could be turned
off), but the broader question is, should this be a warning condition at all?
Put another way, should a return of FDFErcNoValue for FDFGetValue be considered an event worth
generating a warning?
