way to undo those changes without further changing the document illegally. Do the following:
Contact the sender to resolve the problem. Secure the workflow so that illegal changes are

7.5.2.1 LiveCycle Dynamic Forms and the Warning Triangle

Document Integrity Checks for 8.0
Acrobat 8.0 considers all scripts executed during document construction to potentially modify the
document even if it's designed with a read-only query or some other "no change" action. The presence
and detection of those scripts would trigger Acrobat to display the yellow warning triangle, thereby
indicating that the document may have changed. Scripts that invalidate certification would be prevented
from executing so it would not be possible for such scripts to invalidate certifying signatures.
Document Integrity Checks for 8.1
Acrobat 8.1 does not consider all scripts executed during document construction to potentially modify the
document, and the detection of a script does not cause Acrobat to flag the document as changed. The
application compares the digitally signed and current document versions to determine if the current
version has been modified. If there is a change, then a warning triangle appears on the approval signature.
For example, the following changes are detected:
Changes to the value of an LiveCycle form field (including clearing it).

Changes to the properties of an LiveCycle form field.

