Hello All,
I'm extremely new to lightning components and trying to replace some of our custom javascript buttons with lightning compatible options.  One button takes ownership of a lead.  I found a post that does something similar for cases and tried to modify it for my purpose: https://learnownlightning.blogspot.com/2018/01/change-owner-update-record-using.html

It seems to be doing the record update based on apex code, but it launches a quickaction screen with a cancel button that doens't go away.  I've seen it posted that you can use 

$A.get("e.force:closeQuickAction").fire();

It is not working for me.  I'm not sure if I'm not puting that code in the right place but I'm hoping someone can help me figure out a way to click the quick action button, have the lead change ownership, and that's it.

Here is my code so far:
Component:

<aura:component implements="force:lightningQuickAction,force:hasRecordId" controller="LightningComponent_MoveToMarketing" access="global" >
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>    
</aura:component>

Controller:

({
 doInit : function(component, event, helper) {
        var leadId = component.get("v.recordId");
        var action = component.get("c.changeOwnerMethod");
        action.setParams({
            leadId : leadId
        });
        action.setCallback(this, function(response) {
            if(response.getState() === "SUCCESS") {
                console.log("Lead Owner Changed To Current login User");
             var rec = response.getReturnValue();
             console.log(rec.OwnerId);
            }
        });
        $A.enqueueAction(action);
$A.get("e.force:closeQuickAction").fire();
        $A.get('e.force:refreshView').fire();
 }
})

Apex Class:

public class LightningComponent_MoveToMarketing {

    @AuraEnabled
    public static Lead changeOwnerMethod(Id leadId) {
        if(leadId != null) {
            Lead l = [SELECT OwnerId FROM Lead WHERE Id = :leadId];
         l.OwnerId = UserInfo.getUserId();
//update case Ownerid with loggedin userid.
            update l;
            return l;
        }
        return null;
    }

}

Any ideas?
 

Hello, I'm seeing a lot here in the forum and in Salesforce documentation about offline (store and sync) functionality not being available in HTML5 mobile applications using the API unless they are hybrid mobile apps.  

However, this example application written using only HTML5 techology provides just that:  
https://github.com/ForceDotComLabs/mobile-ui-elements 

Example running on Heroku here:  https://sfdc-sobject-editor.herokuapp.com/  

The documenation for this application says it uses smartsync and smartstore for secure offline storage and sync but like I said I've seen everywhere else that this isn't possible. Can someone provide some insight on this?

Thanks
