Using Default Script Base in a Value Set Provider attribute

0
Gustavo Monti Rocha (25●13●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.
