I creating a Screen Action LWC on Account Record

But I want to launch the Screen Action only if some fields are blank, in our example: Report__c

So I wanted to implement connectedCallback() in order to check before the rendering the fields, and if it's not blank it will close the Quick Action with a Toast Message such as " A report already exist in this account.." I also tried renderedCallback() but it is worse.

getAccountReport.html :

<div class="spinner">
    <template if:true={isLoading}>
         <lightning-spinner class="spins" alternative-text="Loading" variant="brand" size="medium">
    <div class="slds-var-p-around_small">
        <lightning-card variant="narrow">
            <h1 slot="title">Are you sure to Request a Report for this Account ?</h1>
            <div slot="footer">
                <lightning-button class="slds-var-p-around_x-small" label="Cancel" onclick={closeAction}></lightning-button>
                <lightning-button class="slds-var-p-around_x-small" type="submit" label="Get Report" variant="brand" onclick={handleGet}></lightning-button>

getAccountReport.js :

import { LightningElement, api, track, wire } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
import { getRecord } from 'lightning/uiRecordApi';
import NAME_FIELD from "@salesforce/schema/Account.Name";
import REPORT_ACC_FIELD from "@salesforce/schema/Account.Report__c";
import { CloseActionScreenEvent } from "lightning/actions";

import getAccountReport from '@salesforce/apex/WS_Account_Report.getAccountReport';

export default class getAccountReportQALWC extends LightningElement {
    @api recordId;
    @track isLoading = false;
    @wire(getRecord, {
        recordId: '$recordId',
        fields: FIELDS
    handleGet() {
        this.isLoading = true;
        getAccountReport({accId : this.recordId })
            .then((result) => {
                this.isLoading = false;
                if(result != true && result != 'true'){
                    this.showToastMessage(2,'The report was successfully downloaded');
                this.dispatchEvent(new CloseActionScreenEvent());
            .catch((error) => {

    showToastMessage(fromWho, mess, urlToast) {
        var variantToast;
        var titleToast;
        if(fromWho == 1){
            variantToast = 'info';
        else if(fromWho == 2){
            variantToast = 'success';
            titleToast = 'Success'
        const toastMessage = new ShowToastEvent({
            title: titleToast,
            message: mess,
            variant: variantToast,
            messageData: [
                    url: urlToast,
                    label: 'here'

    connectedCallback() {
            //This doesn't work
            //This is working
            this.showToastMessage(2,'A report already exist in this account..');
    closeAction() {
        this.dispatchEvent(new CloseActionScreenEvent());

Why the close action doesn't work in connectedCallback() ?

How can I do to not open a screen action when the account doesn't meet the requirement ?

You can use imperative apex here as your apex calls needs to be dependent.

You can call fire an apex call first to fetch the data for Report__c field and show the toast if Report__c is true and fire CloseActionScreenEvent orelse do your other logic.

  • It's seems a good way ! But where I call my imperative apex ? Because if it's in connectedCallback() I just can't fire a CloseActionScreenEvent

  • Try calling it after the apex has returned the value. Jul 8, 2021 at 6:57
  • But where I call it ? It's not clear, I just want the screen action to not be displayed at all if the account doesn't meet the requirement ?
