Signature field corruption problem



I have a dynamic form which is digitally signed when complete. The user can save the signed form on his/her local machine (using a save button on the form).

My problem is: When I open the signed and then saved form again, the signature becomes corrupted. Is it something expected to happen?

I have some initialization scripts which set some fields visible and others invisible depending on the data in the form. Could this be a reason?

I heard something about delta objects, but I am clueless how to use those.

any example would be very helpful.


Any help/guidance would be highly appreciated. Thanks
