[TYPO3-dev] FAL - File record linked in flexform

[Philipp Wrann]

How do i set up a flexform field to store a file relation with uid instead of the path?
I cant work with file_references 'cause i use flexform sections and as i know that is buggy

I simply want to store the files as uid of the sys_file record, instead it is stored like:

3:PATH/TO/FILE

Now - if someone renames a file it wont be found in the system.

My flexform configuration for that field:
image->TCEforms->config:
type: group
internal_type: file
allowed: jpg,gif,png,jpeg
show_thumbs: 1
minitems: 0
maxitems: 1
size: 1

How can i configure the flexform to simply save the files uid?
