The compiler then tells me that he can't convert WithTestLayout<ParentCtrl> to const Upp::Value& (I guessed that before compiling but better try)
So my question is: Is there a way to achieve this or do I have to write my own ParentCtrlList?

ColumnList can, at this moment, only contain Values, not widgets.
If multiple columns are not important for you, you might consider using ArrayCtrl and ArrayCtrl::SetCtrl (that puts general widget into ArrayCtrl cell).
