As I mentioned in my prior email, you need to set the value attribute
in the tr:selectOneChoice tag to be an el expression that resolves to
a property in a backing bean.
ie. value="#{myBacking.selectVal}"
selectVal would be defined as a String and would have a getter and
setter. To select a default select item, you would have the value of
selectVal to the desired selected value
ie
String selectVal = "1";
