Parent Child Table Selection

Hi,

I have created a custom BO with 0 to n multiplicity nodes (3 level) and intend to display it in Parent Child table manner. See the first screen shot.

In the data model tab, I've bind it to the datalist. See the second screen shot.

It works fine in the desktop silverlight mode. See the third screen shot.

However, when i tried in responsive UI mode, the second node is not shown. Same thing applied in IPad Cloud4CustEx. See the last screen shot.

Any idea?
