Usage considerations

Suggestions and permissions

Suggestions are based on the fields used in the record title. This is equivalent to the search functionality in a feed-style record list.
- If you are having trouble getting your record picker to work for an expression-backed record, make sure the record list search is working correctly. See the Expression-Backed Record Tutorial for an example of how to configure this.
Only records that the viewing user has permissions to see appear in the suggestions list, as determined by the default filters on the record type.

Selections and placeholders

Any nulls in the array passed to selected records are not displayed. A [Not Available] token is displayed for any invalid identifiers in the selected records array.
All selected record tokens include a link to the record.
The component always saves an array regardless of how many selections have been made.
This picker cannot be used to selected records of a rule-backed record type (deprecated).
Whether placeholder text clears on focus or input varies by device and browser.

Examples

Copy and paste an example into the INTERFACE DEFINITION in EXPRESSION MODE to see it displayed.

Record type object references are specific to each environment. If you copy and paste these examples into your interface, they will not evaluate. Use them as a references only.

Select a record from a record type

a!localVariables(
  local!storedRecord,
  a!pickerFieldRecords(
    label: "Choose an Employee Record",
    /* For the "recordType" parameter below, replace the record type reference (recordType!Employee)  
     * with a valid record type reference in your environment. 
     */
    recordType: recordType!Employee,
    value: local!storedRecord,
    saveInto: local!storedRecord
  )
)

Displays the following:

Select a record from a record type with a filter

a!localVariables(
  local!storedRecord,
  a!pickerFieldRecords(
    label: "Choose an Employee Record",
    /* For the "recordType" parameter below, replace the record type reference (recordType!Employee)  
     * with a valid record type reference in your environment. 
     */
    recordType: recordType!Employee,
    filters:{ 
      a!queryFilter(
        field: "department",
        operator: "=",
        value: "Engineering"
      )
    },
    value: local!storedRecord,
    saveInto: local!storedRecord
  )
)

Displays the following:
