server side error when file field inside group

[pwkip]

there is a bug when a file field is inside a hidden group.

This will not work (throws 500 ERROR server side):

[text a]
[group g]
  [file file-2]
[/group]
[submit]

Temporary workaround for now:

Change file fields inside groups to required file fields, like this:

[text a]
[group g]
  [file* file-2]
[/group]
[submit]

Then it will work.

Additional problem when file field inside nested repeater.

Required file field is not marked as invalid when empty if it's inside a nested repeater.
