Problem using x:radio with the RI

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

Peter

The MyFaces implementation also returns a Long value for #{0}. The JSF 
spec refers to the JSP 2.0 spec which suggests the value could be a Long 
or BigInteger as the result of an integer expression. Therefore this 
suggests that the cast should be to Number in both HtmlRadio and 
HtmlCheckbox. I will raise a bug.

Don't know since I haven't tried it with either.  Why don't you try it
with MyFaces impl to see if it works as you expect?  If it doesn't
then report it as a bug in JIRA and someone will take a look.  I'd
also check the spec to see if this isn't the specified behavior.
