LWC within omniscript not refreshing based on value changes in omniscript

@track osData captures the omniJsonData reference ONCE at initialization When you change the form dropdown in Omniscript, it updates this.omniJsonData But this.osData still points to the old object reference Your getPortalUrlFromApex() uses stale data > No refresh!

3 lines to change

Replace your tracked property with a GETTER:

Original (WRONG): @track osData = this.omniJsonData; // WRONG Fixed (RIGHT): get osData() { //
return this.omniJsonData; } That's it! Now when Omniscript changes the value:

Omniscript updates this.omniJsonData LWC's getter always returns the current value Your getPortalUrlFromApex() gets fresh data

Here is the corrected code fo ryour component

import { LightningElement, api, track } from 'lwc'; import { OmniscriptBaseMixin } from "omnistudio/omniscriptBaseMixin"; import getPortalUrlFromApex from '@salesforce/apex/MNRF_NewPermitComponentCTRL.getPortalUrlFromApex'

export default class MnrfOSStartSubHelpUrl extends OmniscriptBaseMixin(LightningElement) {

@api record;
portalUrl;
portalTitle;
@track aggFormId;

//  FIX: Replace @track osData with getter
get osData() {
    return this.omniJsonData || {};
}

connectedCallback() {
    console.log('Inside MnrfOSStartSubHelpUrl: connectedCallback - record:', this.record);
    console.log('Inside MnrfOSStartSubHelpUrl: connectedCallback - omniJsonData:', JSON.stringify(this.omniJsonData));
    
    this.aggFormId = this.osData.FormSelection?.AggForm;
    console.log('Inside MnrfOSStartSubHelpUrl: connectedCallback - aggFormId:', this.aggFormId);
    this.getPortalUrlFromApex();
}

renderedCallback() {
    console.log('Inside MnrfOSStartSubHelpUrl: renderedCallback - record:', this.record);
    console.log('Inside MnrfOSStartSubHelpUrl: renderedCallback - omniJsonData:', JSON.stringify(this.omniJsonData));
    
    //  Check if form selection changed
    const newAggFormId = this.osData.FormSelection?.AggForm;
    if (newAggFormId !== this.aggFormId) {
        console.log('FormSelection changed from', this.aggFormId, 'to', newAggFormId);
        this.aggFormId = newAggFormId;
        this.getPortalUrlFromApex();  // ← Re-fetch portal URL
    }
}

getPortalUrlFromApex() {
    console.log('Inside MnrfOSStartSubHelpUrl - getPortalUrlFromApex - record:', this.record);
    
    getPortalUrlFromApex({ templateId: this.record })
        .then(result => {
            console.log('Inside MnrfOSStartSubHelpUrl - getPortalUrlFromApex:result:', result);
            let resString = result.split(";");
            this.portalUrl = resString[0];
            this.portalTitle = resString[1];
            console.log('Inside MnrfOSStartSubHelpUrl - Portal URL retrieved:', this.portalUrl);
        })
        .catch(error => {
            console.error('Error in getPortalUrlFromApex:', error);
        });
}

} ⚡ OPTIONAL: ADD POLLING FOR GUARANTEED UPDATES If the above fix alone doesn't work, add this polling mechanism:

connectedCallback() { // ... existing code ...

//  Add polling as fallback
this._refreshInterval = setInterval(() => {
    const newFormId = this.osData?.FormSelection?.AggForm;
    if (newFormId && newFormId !== this._lastFormId) {
        this._lastFormId = newFormId;
        this.aggFormId = newFormId;
        this.getPortalUrlFromApex();
    }
}, 500);  // Check every 500ms

}

disconnectedCallback() { // Clean up polling if (this._refreshInterval) { clearInterval(this._refreshInterval); } } Omni Configuraiton (Right side panel)
Make sure your LWC property binding in Omniscript is correct:

Property Name: record Property Source: ={FormSelection.AggForm}

OR if you need the entire FormSelection object:

Property Name: record Property Source: ={FormSelection}

Important: Use ={} syntax, not % syntax!
