FileField overwrite existing value with empty one

[pierpaolodf]

Since revision 9766 editing in admin will cause overwriting existing value in FileField with blank value.

1) create a new record setting FileField to some file and save it

2) edit the previous record in some field other than the FileField (or just save with no change)

3) check the record to find out that FileField is now empty

This has been already reported in #10121, although it was about ImageField I'm closing this as a duplicate because ImageField is a sublcass of FileField

... this as a duplicate because ImageField is a sublcass of FileField

This is why it is better to leave this one open not #10121

Convention is to keep the first ticket opened for a problem and close subsequent ones as dupes (though sometimes it is not always realized there is an older ticket already covering a new report, so it is not a convention always 100% followed), noting in the original if necessary anything pertinent. It's been noted the in #10121 that the problem is not specific to ImageField, that's good enough. We only need one ticket to track the problem and it's not particularly critical which one is used.

Ok, thanks for explanation. I'm removing my e-mail from cc then.
