Typeahead from ExtensibleForm not Filling With Patched Value

[erdemcaygor]

Description

Typeahead input in abp-extensible-form is not updating properly when a patched value is applied through patchValue() or form initialization.

Reproduction Steps

• Initialize a form with abp-extensible-form, including a Typeahead field.
• Observe that the Typeahead input remains empty during the data update process

Expected behavior

• The Typeahead field should display the patched value as soon as the data is updated.

Actual behavior

• The Typeahead input stays empty while the data is updating

Hi, are there any recent developments or updates regarding this issue?

Hello,

If you are using a Typeahead-typed field in your form, you also need to add another field with the same name but with the suffix _Text to store the selected key from the Typeahead field. This field is automatically populated when the Typeahead selection changes.

Here’s an example usage:

  {
    type: ePropType.Typeahead,
    name: 'state',
    displayName: '::State',
    id: 'state',
    options: data => {
      return of([
        {
          key: 'Active',
          value: 'active',
        },
        {
          key: 'Passive',
          value: 'passive',
        },
      ]);
    },
  },
  {
    type: ePropType.String,
    name: 'state_Text',
    displayName: '::State',
    id: 'state_Text',
    visible: data => false,  // Hidden field to store the selected key
  }

Thanks for the tip. Is this a work-around or a definitive solution? Can it be used right away or will it only be available in a future patch? I tested it on my project and it still didn't work

Hello,
Yes, you can use it right away, and this is the definitive solution. Could you please share your form props, the save request body, and the detailed response body?

Hello

The issue is that your response does not include the organizationUnitId_Text field, which is required for the Typeahead field to work correctly.

Could you please add the organizationUnitId_Text field to your response?

While the solution functions, it appears to introduce unnecessary complexity compared to the streamlined behavior of the abp-lookup-typeahead component. Optimizing this implementation to achieve similar efficiency and simplicity is desirable
