  Error Object Specs
  Each object represents a field, and contains all the active validation issues for that field
  {
    show: yes/no - whether or not the message displaying in the UI
    autoHideAfter: Int - ms to hide the error after
    direction: 'left/right/above/below' - defaults to below - direction of the message pvr
    messages: [] - array of error message strings
  }
