in example have dropdown field name: mykb , display name: kb. in ws api name shows prepended c_, in c_mykb. however, if use c_mykb error comes up:

uncaught rally.ui.combobox.fieldvaluecombobox._populatestore(): field config must specified when creating rally.ui.combobox.fieldvaluecombobox

use display name of field, without spaces. here screenshot showing app in action: enter image description here
