Bug with term mappings

[SevKohler]

If i map a code to a coded_text with term mappings.
I cannot work on the output of the coding.
It will simply not take the term mappings then in consideration.
So just the standard code is mapped.
The idea here is map all the stuff and for a specific coding mapping i want to enter it an manipulate it which is not working.
