Problem using x:radio with the RI

[Peter Mahoney]

There seems to be a problem using the x:radio component with the RI. I 
am using a dataTable to list each of the options, one per row. I 
therefore need to use an expression to provide the index attribute. The 
RI resolves the value of the expression to a Long, however HtmlRadio 
casts the value of the expression to an Integer. The RI returns a Long 
value for the expression #{0}. As a fix, I have changed the cast to Number:

       Number v = vb != null ? (Number)vb.getValue(getFacesContext()) : 
null;

Is this a bug with the RI or MyFaces?
Thanks
