I am attempting to build a button that will close a modal, I have tried multiple different ways. I have attempted to close it using the promises or component.find('overlayLib');

I have a component where I'm building out an overlay

<lightning:overlayLibrary aura:id="overlayLib" />

I built it in my controller in a button click it opens.

showModal: function(component, event, helper) {
    var modalBody;
    var modalFooter;
    modalBody = component.get("v.modalBody");
    modalFooter = component.get("v.modalFooter");
        header: "Add",
        body: modalBody,
        footer: modalFooter,
        showCloseButton: true,
        cssClass: ""
    }).then(function (overlay) {
        component.set("v.modalPromise", overlay);

And then I try to close with this this logic, and fire an event..

handleSave: function(component, event, helper) {  
    var value = component.find("inputTextAreaID").get("v.value");
    var row = component.get("v.row");
    var dataTableID = component.get("v.datatableID");   
    var column = component.get("v.column");

    var overlayPanel = component.get("v.modalPromise");


    var cmpEvent = component.getEvent("cellChangeEvent");
        "value": value,
        "rowIndex": row.rowIndex,
        "row": row,
        "fieldName": column.fieldName,
        "dataTableID": dataTableID


My console then spits out the details

I've checked out all the solutions that have been posted here.. Does anyone have a surefire way of solving this?

  • i think there might be an issue with the component, i tried the example in the documentation, and when using notifyClose() method with the latest API version, it throws "Exception: TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them at", which is a bummer

    Attribute v.modalPromise is not defined or not included in your code snippet?

I finally figured it out, I was creating the promise incorrectly, I needed to do the var declare

var modalPromise = component.find("overlayLib").showCustomModal({
        header: "Add",
        body: modalBody,
        footer: modalFooter,
        showCloseButton: true,
        cssClass: ""

Then set it

component.set("v.modalPromise", modalPromise);

Then when ever I needed to close it I called

        function (modal) {

There is an answer here https://salesforce.stackexchange.com/a/193928/4726 which I thought I tried but must of implemented it incorrectly

  • What does your attribute definition look like for modalPromise? Aug 14, 2021 at 20:00
