I am facing an issue. My nintex form supports file uploads.
When it comes to approval ( edit task form) , the tatachments doesn't show up, since i have customized my task form.
it's not because of your customization, it's so by design. your 'nintex form' and 'edit task form' work on different lists so they doesn't see attachments from the other list.
here you can find how you can make list's attachments available on task form collect task attachments in list item and show all attachments in next task
When i dont customize the task form, the attachment does display.
But the moment i move even a single control to re align, the links on the page vanishes, which include link for attachment and link for the list item.
Do you know why ?
