If your children are articles, there are two mistakes here :

1. xar:data-view only works with "complete" objects (with a primary key
etc.), not extensions of some articles pubtype.

For articles, you need to :
a. call DD getitems() to retrieve the itemids
b. call articles getitemlinks() to retrieve the article titles and links
[or call articles getall() if you want more]

2. (module + itemtype) determines which DD object we're talking about,
so typically for articles extensions you would have something like

module="articles" itemtype="$ptid"

In your example, the child object belongs to the dynamicdata module,
itemtype 126, not to articles pubtype 2 (or whatever).

Of course, if your children are not articles but a separate dynamic
object, then you might use that approach :-)
