Rather than String, try using Long for your accessors.
By default, accessors for literals must either be String or Long or Double.
#{1} is a new Long(1), not a new Integer(1).
Yes, a converter will work automatically, so if you were to provide
#{something that evaluates to an integer}, then everything would work
as you expect. But the problem is that you're not generating
Integers.
But, again, El returns Longs "#{1}", Strings "1", and Doubles "#{1.1}"
for literals, not Integers or any other type.
So if you had a facelets toInt() method, you could do:
"#{myFunction:toInteger(1)}"
Your other option is to do what Rene suggests and provide a method
that returns SelectItem<Label:String,Value:Integer> select items from
your java code
