How to get value from sessionscope in radiogroup for XPages

问题

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)
