Reproduction steps:
1) Set language to Italian
2) Create a document type "Test" with a ddm-decimal field.
3) Create a "Test" document
4) Insert in ddm-decimal field a value with comma separator (that is correct for italian locale).
5) Publish document
6) Edit the document and open "information"

Actual result: The value save is "0.0"
Expected result: The value is the numer that we wrote
