A
complex data type used by the
Modify Signature Field operation
operation provided by the Signature service.
It contains information about the signature fields in a PDF document.
The information includes which signature fields are locked when
the signature field is signed, and constraining information that
is used at the time the signature is applied.
For information about data that can be accessed using Xpath Expressions,
see
Data items
.
For information about configuring default properties, see
Datatype specific settings
.
Data items
The data items that
PDFSignatureFieldProperties
variables
contain.
fieldMDP

The locking action that occurs when the signature field is
signed.
-

Sets a comma-separated list of field names
that indicate which fields the action is applicable or not applicable
to. This option is available when Field Locking Action option is
set to a value of Include Fields or Exclude Fields.
Seed Value Options Spec
Properties for the document signature.
For the properties that are formatted as an editable list, use
the following buttons to manage the list:
-
Add
A List Entry:
-
Adds an entry to the list. Depending on the option, type the
information, select an item from a drop-down list, or select a file
from a network location or computer. When you select a file from
a location on your computer, during run time, the file must exist
in the same location on the LiveCycle server.
