Please give a brief summary of your issue:
PDFTron is displaying a white screen when signature field is not signed
Please describe your issue and provide steps to reproduce it:
We’re currently using a custom “Sign Here” image to sign and create the signing modal (using a TextField component). Some users have reported an issue where they can sign the modal but are able to click outside the signing modal which closes the modal and does not sign the field.
By not clicking “Create” after signing, when you try to reopen the signature dialog box then it will white screen.
We think we could solve the issue we’re seeing if we could prevent the user from closing the modal by clicking outside of it and only closing the modal based on saving the signature (using the create button on the modal) or cancelling.
Please provide a link to a minimal sample where the issue is reproducible:
