DatForm and floating point data

MaximSpikin

Hi

I try to use FeatureDataForm to edit FeatureLayer.
Everything works fine (Geometry, string Fields, Data field edit and saved),
but if I edit an existing layer the data in floating point (type Double) - no data is saved.
As I understand, the problem is in the system regional settings - system decimal separator

ArcGIS 10, Silverlight API 2.2 (build 629), system decimal separator = ","

example: 
              72.1 => data is not saved and Commit button not enabled
              72,1 => data is stored as 721

if I change the system decimal separator on "." all OK, but I can not change the settings for all clients
How do I save floating point data?

Thanks

Can someone please define what "Floating Point Data" is and an example?
