We need to get the attachments from an email and display on a form created within the Appian forms designer. We save these attachments in a variable and use the documenttable to display them. But within the form is always empty (using a message component). How can we fix this?
We are in version 7.7.

Ps. These files are in a folder created using the component create folders...
