I have a lightning-record-edit-form that includes few standard fields few custom fields. I've register onsuccess(event) function that does some stuff with the newly updated record. I'm accessing this data using the event.detail.fields object. I'm referring to the field names using their API names (imported them to the JS file). This works perfectly fine in my dev org.

When packaging this component, it stops working. When saving the record, the event.detail.fields is not filled with the custom fields I have on this object and the code crushes when I'm trying to refer to it (reminder: with the valid API names I imported). The thing is, the data is being saved and if I refresh the page, I see the edits I made for both standard and custom fields. I tried checking permissions but the user has full edit access for both objects and the custom fields.

I tried examining the event.object.fields and see what it contains and it really doesn't have my custom fields :-\ (and in my dev org, it does).

What am I missing here?

Template code:

<lightning-record-edit-form object-api-name="ServiceTerritory" record-id={Id} layout-type="Compact" onsuccess={handleSuccess}>
    <lightning-input-field field-name={apiFieldCustomFieldName}></lightning-input-field>
    <lightning-button class="slds-m-top_small" type="submit" label="Save">

Hand picked JS code (only relevant):

import CUSTOM_FIELD_NAME  from '@salesforce/schema/ServiceTerritory.Custom_Field__c';

apiFieldCustomFieldName = CUSTOM_FIELD_NAME.fieldApiName;

handleSuccess(e) { 

    const fields = e.detail.fields;


    // TRUE in dev org, FALSE in managed package


(don't worry, everything is declared the right place of the file).

When debugging, I do see the namespace on the manage package. And again, it saves fine but the object on the onsuccess is not returned with all the fields

  • Try adding the package namespace to the fields API names on the lightning inputs, also refer the same in onsuccess. May 18, 2020 at 8:41

    @rahulgawale - I did, this why I said I imported the API names. The data loads fine and even saved fine (you can see it only after refresh). The only issue is that the onsuccess doesn't include this data on the updated record (event.detail.fields)

Well, it seems like the fields that are returned in the onsuccess events are the one that are configured in the page layout. After putting all of these fields in the layout - I get the updates in the event.detail.fields as expected.

  • When you say on page layout, you mean referred by lighting-input-field? May 18, 2020 at 12:01

    Nope, the default page layout you have on the object manager
