Hi,
While the id for h:selectOneMenu can be any Object in JSF RI, it has to be a
String value > in myfaces....
This is not the case.
If you have correctly setted up a converter for the value of a
SelectItem you can use any type. In your case this would be converting
from String to Integer and vice versa.
cheers,
Gerald
