You want to prefill the attachment when it is added to the form?

Thanks jagjeetthukral​

Thanks,The issue which you have mentioned is due to number higher that javascript's limit for numbers being converted to exponentional or scientific notations ex 123.11e26.This issue is at Javascript's end and not at AEM Forms end. You can go to browser's console, create a "var a = 1111111111111111111111111111111111111111111" and then just get alert(a), you will get out put in exponential notation.As a solution, I will suggest you to use text field with pattern validation for number, but bear in...

It allows you to swap the xdp reference to a completely different one though e.g. from Test.xdp to ABC.xdp, that would have the same potential problem of leading to binding errors. I think we both agree that changing things in the JCR manually is a last resort, but given a lack of an alternative in the UI it is the workaround I would use.I would still be keen to get someone from the forms development team's opinion on whether this is something that should be added to the UI.

Glad james was helpful. This is the point of the AEM community. To try and help as much as possible.
