Using Default Script Base in a Value Set Provider attribute

0	Gustavo Monti Rocha (25●11●16) \| asked Jan 27 '15, 8:51 a.m. When a workitem is loaded, we have an attribute called "UG" that is loaded (on click event) with Value Set Provider Script (values is provided from webservice). How can I set a Default Value to this attribute?

You can specify a default literal for an enumeration in general.
You can also define a default value provider for an enumeration or enumeration list similar to the value set provider. See https://jazz.net/library/article/1093 Lab 4.

Ralph,

But How to do that based on fact that attribute isn't loaded yet with value script provider?

If this was loaded on creation, maybe I could get the values...

Read lab 4 above. The default value kicks in when the work item is CREATED.

I read lab 4 in this article ( https://jazz.net/library/content/articles/clm/2012/process-enactment-workshop/workbook/pew-rtc-lab-workbook.pdf ) but I didn't find the awnser.

I saw that we can choose the default value (default script base) if my attribute is a enumeration but my attribute loaded with Value Set Provider Script (values is provided from webservice).

In attribute customization, create default value provider for enumeration list.
Select your enumeration and the default you want
In the work item attributes, select the default value provider now available for your attribute
done

If you load from a web service it is likely script based - and not enumeration based.

I load from a web service.

How can I load the values (from webservice) using getDefaultValue function?

In getFilteredValueSet function we use the context to retrieve data like this:

var connector= context.getDataConnector("HttpConnector");

The problem is the in getDefaultValue we don't have the context variable:

getDefaultValue: function(attributeId, workItem, configuration) {}

I don't know if is the best to do this.

You can try a script based default value using the HTTP filtered value set in the script like explained here: https://jorgediazblog.wordpress.com/2012/06/27/work-item-customization-httpconector-and-oauth-in-rtc-4-0-for-oslc/

But I am not sure if that would work.
