To reference the arrayed values, the first entry is referenced with the property name. Subsequent values are referenced by specifying three underscores and then a number, beginning with 1, after the property name.
For example:
The first version of a work item contains the keys:
name=“John Doe”, age=“37”, company=“Enterworks”.
The second version contains the keys:
name=“Jane Doe”, age=“36”, company=“Enterworks”.
In the TaskManager, the merge activity produces the following properties:
name= “John Doe”, age=“37”, name__1=“Jane Doe”, age__1=“36”, company=“Enterworks”.
Note: There is no guarantee that the indices for each arrayed property will correspond with the other arrayed properties. With the above example, it is possible to have:
age=“36”,age__1=“37”.
In the Design Console, the Array Index column inside the Properties tab of the Work Item Version editor displays the index of the values of the work item versions that have the same property names that were merged. The work item version obtaining the first index is the work item version who arrived first. In the example, the work item property key age with the value 36 received the index 0, while the work item property key age with the value 37 received the index 1.
