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.
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
