How to get value from sessionscope in radiogroup for XPages - xpages

Question

We have an XPages application that is setup with help of Notes keyword documents. These keywords are made available via sessionScopes. An example of a scope variable is:
name scope: key_customer_sv
values:
default
values [Yes, No]
For the values I am using a LinkedHashSet to guarantee the insertion order:
var values:java.util.LinkedHashSet = new java.util.LinkedHashSet();
var iterator = keyValues.iterator();
while (iterator.hasNext()) {
var itemvalue = iterator.next();
values.add(itemvalue);
}
map.put("values",values);
The values are stored as as HashMap and the pair names are default and values.
For my xp:radioGroup control I want to read the scope variable and return the values of the value entry.
How must I do this?
Here is what I tried:
var language = "_" + context.getLocaleString();
var languageDefault = "_" + "sv";
var key = "customer";
var values;
try{
values = sessionScope.get("key_" + key + language )['values'];
}catch(e){
print(e);
}
if (null == values){
values = sessionScope.get("key_" + key + language Default)['values'];
}
return values

This works for me:
var language = "_" + context.getLocaleString();
var languageDefault = "_" + "sv";
var key = "customer";
var values;
try{
values = sessionScope.get("key_" + key + language ).get('values');
}catch(e){
print(e);
}
if (null == values){
values = sessionScope.get("key_" + key + languageDefault).get('values');
}
return values==null?"":values.toArray();
It is important by getting values using .get('values') instead of ['values'] , because it returns something different.
I tested is by filling sessionScope with this code:
var key_customer_sv:java.util.HashMap = new java.util.HashMap();
var values:java.util.LinkedHashSet = new java.util.LinkedHashSet();
values.add("Yes");
values.add("No");
key_customer_sv.put("values",values);
key_customer_sv.put("default", "Yes");
sessionScope.put("key_customer_sv", key_customer_sv)
