Hi Stephen
Thank you for your answer, I was on holiday and did not get time to replay you befor.
View columns are sorted (ascending) but as view contains only alias code (not real text).
I uploaded a picture of the design view and xpages result.
Here is the rest service code :
viewName="(xLanguage)" contentType="application/json" var="entry">
}}]]>
var key = "LANGUAGE~" + entry.getColumnValue("language") ;
var lookup = @DbLookup("", "(keyWordsView)", key, 2) ;
return lookup ;
}]]>
var key = "LANGUAGE-LEVEL~" + entry.getColumnValue("speak") ;
var lookup = @DbLookup("", "(keyWordsView)", key, 2) ;
return lookup ;
}]]>
