When adv_search_button_apply method is called, x_node is changed to "root" node because we are in explorer screen. BUT there is no root node in My Services! So then @right_cell_text is nil (and it shouldn't be) so it throws an error.
The issue is not present if you apply a filter by clicking on a name of the filter from accordion.
