    You cannot use the vairable directly you may want to extract something from the attributes e.g. SMSESSIONID or look at the example over here

    I got this Ronald,

    but what if we may want to extract all the values from siteminder.smcontext.attributes? (as this a multi-valued thing)

    Which version of Gateway are you using. if you are using version 9.4 you can actually get the information from mutivalued variable using JavaScript assertion. extract attribute and then traverse for response.
    var multiValues= context.getVariable('request.http.parameters.multiparam'); //Reading multivalued variable
    for(var i in multiValues) {
    // iterating through multi valued variabes.
    }

    We are currently using CA API Gateway 9.2.

    can we follow this approach (incomplete) to achieve extracting all the values :

    But, thanks for letting us know that we can use JavaScript in 9.4

    Ok Try this
    This basically join all multivalued variables
    Then log the variable smcontext this will give you # seperated values
    Can you send me the output. I can provide you feedback from then

    Option 2:
    • When the content is not a string type, it is generally necessary to add the following text to the end of the context variable in the audit assertion: .mainpart
    • Example:
      • When the error shown in the audit viewer is Variable 'attribute.current' is not a String and cannot be converted to one. (Actual type: com.ca.siteminder.SiteMinderContext$Attribute) the audit assertion logging it should be changed from having a context variable named ${siteminder.smcontext.attributes} to a context variable named ${siteminder.smcontext.attributes.mainpart}
