Hi There! I'm using standard events to create, edit, navigate and delete functionality. The Create, Edit and Navigate functions are working perfectly but when I come to deleting the record, I get an error saying cannot read property 'setParams' of Undefined. Can anyone tell me why it is throwing this error. I dont understand why its not working for delete. below is the js function for delete. I've printed out the recordId when I click on delete button and it is showing the correct recordId. If this is not working then I might have to pass the recordId to apex controller and delete it in a method, But I wanted to use the Salesforce Standard Event for Deleting the record as well. 
Thanks

DeleteRelation : function(component, event, helper){
        
        //Calling the Salesforce defined Standard Event for deleting Record.
        var ACRId = event.currentTarget.dataset.value;
        console.log("deleterecord"+ACRId);
        //Calling the EditRecord Event.
        var deleteEvent = $A.get("e.force:deleteRecord");
        //Setting the Params for the deleteEvent Action.
        deleteEvent.setParams({
            entityApiName : "AccountContactRelation",
            recordId : ACRId 
        });
        //Firing the Event.
        deleteEvent.fire();
        
    },   

Hi There,  I have a junction object that links Contact and my Custom Object. With Standard functionality (Lookup) I can link only one custom object record to Contact. My requirement is to be able to select multiple custom object records and link them to Contact record. For this I'm using a lightning Datatable to display list of custom object records. I'm successfully creating the junction object record with ContactId but I'm unable to get the Id's of selectedRows from the datatable. Below is my CMP code:- Any help is much appreciated.

Winter 19 release has brought this new tag - lightning:map to show google maps in lightning maps. I am trying to implment below example in my dev org, but the map marker is not showing up on the org.

Example given here:https://developer.salesforce.com/docs/component-library/bundle/lightning:map/example

When I check the broswer console, I can see below error:

util.js:218 Google Maps JavaScript API warning: NoApiKeys https://developers.google.com/maps/documentation/javascript/error-messages#no-api-keys
lw.j @ util.js:218

(anonymous) @ stats.js:1
util.js:218 Google Maps JavaScript API warning: InvalidKey https://developers.google.com/maps/documentation/javascript/error-messages#invalid-key

Question1: Do we need to explicitly add google map api key? Only then the map would work? I am assuming that Salesforce should automatically take care of this?
Question 2: If the answer to above question in yes, then how do we add the api key? I have a developer key, but not sure how to add it.

I created a lightning component which is a form for editing a related list on an object. I created a lightning action for the component in the object record details page in salesforce. My problem is that the modal the component shows in when the action is clicked has a small width, and the details for each list item become squished/truncated. Is there a solution/alternative for increasing the width of the modal the lighting component appears in?
