BI4.1 html interface and calendar input

Hi,

i'm facing a strange issue with my BI4.1 SP2 Platform.

I'm using the HTML webintelligence interface and i want to define a query with a condition on a date object

- Source database is sqlserver

- Driver used is OLE_DB

When i activate the calendar object to register my input date, it generates a MM/DD/YYYY date format in the query panel but as a SQL it tries to convert it in DD/MM/YYYY format.

If i select 26 of march 2014 i then get an error because the application tries to generate the date as 03 of month 26 2014...

Actually the format proposed in the query panel via the calendar object differs from the format generated as SQL...

I'm ok with the SQL part because i'm french and it respects me local settings.

I'm not ok with the calendar interface because i would like it to propose me with date in french format, e.g. DD/MM/YYYY

Do you know how i can influence the date format in the calendar input object?

Thanks

Xavier
