Filling a Content Taxonomy Field with Exif Data

Hello,

First of all, sorry for this being my second post for a single day.

Now, my problem is that I want to import some of the exif fields as Taxonomy terms, but the field does not get filled and the taxonomy term is not added.

I created a field called field_ifd0_make for the Camera Make, the field type is "Content Taxonomy Field", with the "Autocomplete (freetagging)" widget selected.

My taxonomy is configured as follow:
Vocabulary called "Exifs", with "Tags" the only checkbox selected in its settings. I added a term in it : "Camera Make".

My Content Taxonomy field is configured as follow:
- Allow and insert new terms by the user into the vocabulary
- Extra Parent for new terms: "Camera Make"
- I Selected Save values additionally to the core taxonomy system (into the 'term_node' table).
- Vocabulary: Exifs
- Parent Term: Camera Make

*Additional note: I can import the data of the field_ifd0_make when the field type is a text field.

Thanks in advance for any help!
