Getting following error while seeing the preview of the mashup.
Something messed up in selected rows ... we have selected rows, but subscriberInfo.selectedRows_anySelectedRows !== true
What will be the causes? I have no idea.

When you saying you're using a nested collection widget, can you verify that you mean you've configured a collection widget within a collection widget? If so, have you validated that it is working at the inner most level?
