Nested hash date and date format

Hi,

We have : 

   Form_A / Table_A With

       Field_A1 : id of Table 1

       Field_A2 : date format yyyy-MM-dd  (date picker, no hour)

   Form_B / Table_B   With

       Field_B1 : id of Table 2

       Field_B2 : FK = id Table 1

Purpose : display on the Form B the date Field_A2 with a hashtag with “dd/MM/yyyy” format, in a html field.

With the hash #binder. Form_A.Field_A2[{binder.Form_B. Field_B2}]#  -> the result is : date display with  “yyyy-MM-dd ” format.

I try : #binder. Form_A.Field_A2[{binder.Form_B. Field_B2}].dd/MM/YYYY#  -> the result is always with “yyyy-MM-dd”.

Is it possible to display this hash with “dd/MM/yyyy” format ?
