We're working on a module that uses GridfieldBulkEditingTools to edit data. However we've found that we're unable to edit file fields on the Bulk Edit page. That is, we can't replace existing files with new ones, or upload new files. The text attributes of the data object are editable just fine.
Can someone please tell me if this is simply a limitation of the module or is there something we can do in our code to sort it out?
Thanks.
