Invoke Flow From Lightning Component With Input Variables

Using lightning:flow component, we can invoke a flow in Lightning runtime. This component requires API version 41.0 and later. Here is an example to delete all Contact records from an Account using a flow.

Here I’ve created a flow and the flow is invoked by a lightning component, and that lightning component is configured with a QuickAction on Account object.

1. Go to Setup | Quick Find – Search Flows | New Flow

2. Create a variable as “AccountId”

3. Create a sObject Collection Variable as “CollectionOfContacts”

4. Create a Fast Lookup to get Contacts with Account Id

5. Create a Decision to check Account has contacts.

6. Default Outcome in Decision

7. Create Fast Delete to delete Contacts

8. Set the Fast Lookup as a starting element, indicated by the green down arrow. Then, connect the flow element “Fast Lookup” to “Decision” and “Decision” to “Fast Delete”.

9. Create a Lightning Component to invoke the flow.

Lightning component:

<aura:component implements="force:lightningQuickActionWithoutHeader,flexipage:availableForRecordHome,force:hasRecordId">
    
    <!--Custom Styles for Modal Header and Footer--> 
    <aura:html tag="style">
        .cuf-content {
        padding: 0 0rem !important;
        }
        .slds-p-around--medium {
        padding: 0rem !important;
        }       
        .slds-modal__content{
        overflow-y:hidden !important;
        height:unset !important;
        max-height:unset !important;
        }
    </aura:html>
    
    <!--Declare Attributes--> 
    <aura:attribute name="hasError" type="Boolean" default="false"/>
    
    <!--Modal Header-->  
    <div class="modal-header slds-modal__header slds-size_1-of-1">
        <h4 class="title slds-text-heading--medium">Delete Contacts</h4>
    </div>
    <!--End Modal Header-->  
    
    <!--Modal Body-->   
    <div class="slds-modal__content slds-p-around--x-small slds-align_absolute-center slds-size_1-of-1 slds-is-relative">
        <form class="slds-form--stacked">
            <aura:if isTrue="{!!v.hasError}">
                <div class="slds-align_absolute-center">
                    Do you want to delete all contacts?
                </div>
                <aura:set attribute="else">
                    <div>
                        <div class="slds-text-color_error">Error on Contact record deletion.
                            Please forward following error message to your admin:</div>
                    </div>
                </aura:set>
            </aura:if>
            <div>
                <!--Lightning Flow Attribute-->
                <lightning:flow aura:id="deleteContactFlow" onstatuschange="{!c.statusChange}"/>
            </div>
        </form> 
    </div>
    <!--End of Modal Body--> 
    
    <!--Modal Footer-->
    <div class="modal-footer slds-modal__footer slds-size_1-of-1">
        <lightning:button variant="Brand" class="slds-button" label="Confirm" onclick="{!c.handleConfirm}"/>
        <lightning:button variant="Neutral" class="slds-button" label="Cancel" onclick="{!c.handleClose}"/>
    </div>
    <!--End of Modal Footer-->
</aura:component>

Lightning JS Controller:

({
    //Confirm 
    handleConfirm : function(component, event, helper) {
        //Find lightning flow from component
        var flow = component.find("deleteContactFlow");
        //Put input variable values
        var inputVariables = [
            {
                name : "AccountId",
                type : "String",
                value : component.get("v.recordId")
            }
        ];
        //Reference flow's Unique Name
        flow.startFlow("Delete_Contact_From_Account", inputVariables);
    },
    
    //Close the quick action
    handleClose : function(component, event, helper) {
        $A.get("e.force:closeQuickAction").fire();
    },
    
    //Flow Status Change
    statusChange : function (component, event, helper) {
        //Check Flow Status
        if (event.getParam('status') === "FINISHED_SCREEN" || event.getParam('status') === "FINISHED") {
            var toastEvent = $A.get("e.force:showToast");
            toastEvent.setParams({
                title: "Success!",
                message: "Contacts deleted successfully!",
                type: "success"
            });
            toastEvent.fire();
            $A.get("e.force:closeQuickAction").fire();
            $A.get('e.force:refreshView').fire();
        } else if (event.getParam('status') === "ERROR") {
            component.set("v.hasError", true);
        }
    }
})

10. Configure above created lightning component on Account object Quick Action.

11. Add created quick action on Account object page layout.

12. Here is the quick action to delete all contacts.

Inherited Sharing in Apex Class

Now you can specify the Inherited Sharing keyword on an Apex class, which allows the class to run your apex code with or without sharing settings, depending on the class that called it.

  • An Apex class with Inherited Sharing enables you to pass security review and ensure that your privileged Apex code is not used in unexpected or insecure ways.
  • An Apex class with Inherited Sharing runs as with sharing when used as a Visualforce page controller, Apex REST service, or an entry point to an Apex transaction.
  • An Apex class with Inherited Sharing is being called from some other class which is having without sharing setting, then it will run in without sharing mode.

Here is an example of an Apex class with Inherited Sharing and a Visualforce invocation of that Apex class. Here the running user sharing access contacts will be displayed. If the declaration Inherited Sharing will be omitted, even contacts that the user has no rights to view will be displayed due to the insecure default behavior of omitting the declaration.

Apex Class:

public inherited sharing class InheritedSharingClass{
    public List<Contact> getAllContacts(){
        return [SELECT Name FROM Contact];
    }
}

Visualforce Page:

<apex:page controller="InheritedSharingClass">
    <apex:repeat value="{!AllContacts}" var="record">
        {!record.Name}
    </apex:repeat>
</apex:page>

Identify Salesforce User Experience Theme in Apex Class

We can use UserInfo.UITheme() and UserInfo.UIThemeDisplayed() in Apex class to determine User Experience Theme.

UserInfo.UITheme() : Returns the theme that is supposed to be used.
UserInfo.UIThemeDisplayed() : Returns the theme that is actually being used.

UserInfo.UITheme() and UserInfo.UIThemeDisplayed() will return following values.

  • Theme1—Obsolete Salesforce theme
  • Theme2—Salesforce Classic 2005 user interface theme
  • Theme3—Salesforce Classic 2010 user interface theme
  • Theme4d—Modern “Lightning Experience” Salesforce theme
  • Theme4t—Salesforce mobile app theme
  • Theme4u—Lightning Console theme
  • PortalDefault—Salesforce Customer Portal theme
  • Webstore—Salesforce AppExchange theme

Sample Code:

String themeDisplayedType = UserInfo.getUIThemeDisplayed();
String themeType = UserInfo.getUITheme();
