Display document name upon uploading the document in the editable grid.

Unfortunately since we still can't access the file properties within the saveInto of a!fileUploadField(), this use case is difficult / impossible to accomplish using only out-of-box functionality.

I will offer that the "content object details by ID" function within the Content Tools plug-in, can access the document's (full) name, though it's a bit of a pain because it by default includes the document's name and extension concatenated together in a longer string that you must extract it from.  But if you're desperate to accomplish this, you should be able to build it using this as a starting point.
