  16          *  fmObject -- If available, the object being edited.  This will be used
  17          *      to set the value of the widget.
  18          *  fmClass -- Class name (not required if idlField or fmObject is set)
  19          *  fmField -- Field name (not required if idlField)
  20          *  parentNode -- If defined, the widget will be appended to this DOM node
  21          *  dijitArgs -- Optional parameters object, passed directly to the dojo widget
  22          *  orgLimitPerms -- If this field defines a set of org units and an orgLimitPerms
  23          *      is defined, the code will limit the org units in the set to those
  24          *      allowed by the permission
  25          *  orgDefaultsToWs -- If this is an org unit field and the widget has no value,
  26          *      set the value equal to the users's workstation org unit.  Othwerwise, leave it null
  27          *  selfReference -- The primary purpose of an AutoFieldWidget is to render the value
  28          *      or widget for a field on an object (that may or may not link to another object).
  29          *      selfReference allows you to sidestep the indirection and create a selector widget
  30          *      based purely on an fmClass.  To get a dropdown of all of the 'abc'
  31          *      objects, pass in {selfReference : true, fmClass : 'abc'}.
  32          *  labelFormat -- For widgets that are displayed as remote object filtering selects,
  33          *      this provides a mechanism for overriding the label format in the filtering select.
  34          *      It must be an array, whose first value is a format string, compliant with
  35          *      dojo.string.substitute.  The remaining array items are the arguments to the format
  36          *      represented as field names on the remote linked object.
  37          *      E.g.
  38          *      labelFormat : [ '${0} (${1})', 'obj_field_1', 'obj_field_2' ]
  39          *      Note: this does not control the final display value.  Only values in the drop-down.
  40          *      See searchFormat for controlling the display value
  41          *  searchFormat -- This format controls the structure of the search attribute which
  42          *      controls the text used during type-ahead searching and the displayed value in
  43          *      the filtering select.  See labelFormat for the structure.
  44          *  dataLoader : Bypass the default PermaCrud linked data fetcher and use this function instead.
  45          *      Function arguments are (link class name, search filter, callback)
  46          *      The fetched objects should be passed to the callback as an array
  47          *  disableQuery : dojo.data query passed to FilteringTreeSelect-based widgets to disable
  48          *      (but leave visible) certain options.
