Is it possible to use a JavaScript value provider to automatically set an enumeration list attribute with a list of values (calculated according to some conditions)?
I am working with RTC 6.0.3.

Hi Don, the discussion does not really answer my question. I need to know ho to set the values a multi-value attribute using a JavaScript value provider. To set a single-value attribute, the script must return its (scalar) value. What kind of variable must be returned when the attribute to set is a multi-value list?

 As Don mentions from the https://jazz.net/wiki/bin/view/Main/AttributeCustomization documentation does state what is supported and list type attributes are mentioned nowhere. I think the list types appeared in RTC after the main JavaScript work was done.


I have never been able to set any list attributes in JavaScript.

Actually, I suspected that JavaScript was not able to set list attributes. I will write a Java extension, instead.

Try to set up a Script Based Value Set. And you need to set the attribute using this value set depend on the "condition"/attribute.

Donald, actually I am no trying to set a Value Set. I am trying to set the values of an attribute, an enumeration list attribute. If I want to insert 3 values into the attribute, what should I do? I mean, the js Calculated Value script must return a variable containing the value to set. For a scalar attribute, it is a scalar variable. What kind of variable can set  a multi-value attribute? Perhaps this is not possible using JavaScript, and I should instead write a Java extension using the server-side SDK.

Ah...sorry for misunderstanding your question. Now you reminds me. IIRC I also had a hard time setting a value of an Enumeration List attribute. I tried CSV, JSON and other imaginable formats but all failed. You don't use a variable, the Calculated Value provider returns a "value" directly. I may give it another crack a bit later. Edit: Have another look at the API spec. Even Enumeration is "limited support", and Enumeration List is not mentioned at all. So I think it's no go for JavaScript.
