I have implemented a lightning app in which I have 2 components
- A modal window component to create an opportunity record
- A summary window component which displays the total number of opportunities along with Total Amount and Expected Amount(based on probability)

Below are the two components 

**************Modal Component***************

<aura:component controller="OpportunityController">

    <!-- UpdateOpptyEvent Sender -->
    <aura:registerEvent name="UpdateOpptyEvent" type="c:UpdateOpptyEvent" />


    <!-- Component Attributes -->
    <aura:attribute name="modalSectionClass" type="String" description="This attribute is used to set class for the modal section" default="slds-modal" />
    <aura:attribute name="backgroundClass" type="String" description="This attribute is used to set class for the background section" default="slds-backdrop" />

    <aura:attribute name="newOpportunity" type="Opportunity" default="{ 'sobjectType': 'Opportunity',
                'Name': '',
                'CloseDate': '',
                'StageName': ''
                }" />

    <!-- slds-fade-in-open-->
    <div aura:id="modalSection" class="{!v.modalSectionClass}" aria-hidden="false" role="dialog">
        <div class="slds-modal__container">

I have a requirement where I want to refresh/reload/update just the summary window component as soon as the user creates an opportunity record (and it is successful) using the modal component(which is implemented for record creation).

PLEASE NOTE : This is a standalone app and it is not in one.app container. So I can't use the force:refreshView thing.  Also I don't want to refresh the whole page. Just the summary component.

As you can see I am already trying to send an application event on the click of "Save" button in Modal component and then handling it on the Summary component. But after handling it I don't know how to refresh that individual component.

Please help!!
 

Hi everyone.
Problem with scroll to top in Salesforce1 (Lightning component).

I have the Salesforce1 app with the content which height much more then display area.  If  scroll down to the bottom is this posible put the button "Top" and if user press this button then the content automatically scrolls up?

Thanks.
