Adding and deleting an attachment gets disabled once the document is signed.

Good morning All,

I have a problem with signed signature. I noticed that Adding and deleting an attachment gets disabled once the document is signed. What is a work around, so, that documents could still be added after it has been signed.

Indeed, I added the following piece of code on the click event on the Signature field, but it does not work.

app.execMenuItem("AddFileAttachment");

Thanks

Tammy
