Hi,

what about adding a new method to FormUtil, similar to 
FormUtil.repopulate(FormMap fm, BComponent bc) but with a slightly 
different signature :  FormUtil.repopulate(Map pm, BComponent bc)

pm would be a plain map containing key / value instead of FormElement. 
This would allow to have a generic (re)population, either from 
previously typed in values (from a FormMap), but also initially from a 
plain map (say a value object coming from the business tier).

The code could be as in the file attached.

Any comments on that ? (maybe there is a much better approch ?)

Regards,

Franck

     * to locate the appropriate form element and repopulate the component based on the 
     * form element value.
