Lightning Aura Components – Identifying Functions Used with Overwritten New Standard Button

button-overrideslightning-aura-componentsnew

I have successfully overwritten the "New" and "Edit" behavior of a custom object with a lightning aura component. Everything is working fine and if the user clicks the related list new button of the parent Account, I can prepopulate the Account in the component using the AccountId of the URL. So good so far.
Unfortunately, if the user clicks the New record shortcut from the object tab, my component prepopulates the Account too. I need to distinguish if the user has clicked the related list "New" or the "New" of the Object tab.
Any ideas how to achieve this?

Solution: Create a custom Quick Action "New" that will be placed on the related list on the Account object. This custom Quick Action can pass parameters into the LWC and due to this, the LWC can distinguish between a click on the custom Quick Action and the Object "New".

Button Overrides – Lightning New Case Action Override

There is a solution that does indeed work, but it's a bit fragile because it's parsing the entire URL (assuming a structure that could change): https://developer.salesforce.com/forums/?id=9060G000000UaqdQAC (look at Pascal Le Clech's answer).

However, we can build on this idea and make it more structurally sound by using https://developer.salesforce.com/docs/component-library/bundle/lightning:isUrlAddressable to grab the new inContextOfRef which gives us a URL Addressable Base 64 encoded string. Here's a slightly more stable solution to Pascal Le Clech's solution:

aura:component

<aura:component implements="lightning:actionOverride, force:hasRecordId, lightning:isUrlAddressable">
    <aura:attribute name="recordId" type="Id"/>
    <aura:handler name="init" value="this" action="{!c.init}"/>
</aura:component>

controller.js

({
    init : function(cmp, event, helper) {
        var pageRef = cmp.get("v.pageReference");
        var state = pageRef.state; // state holds any query params
        var base64Context = state.inContextOfRef;

        // For some reason, the string starts with "1.", if somebody knows why,
        // this solution could be better generalized.
        if (base64Context.startsWith("1\.")) {
            base64Context = base64Context.substring(2);
        }
        var addressableContext = JSON.parse(window.atob(base64Context));
        cmp.set("v.recordId", addressableContext.attributes.recordId);
    }
})
