Create a Lightning Component 'lightningPathExample.cmp' with the following code.

• Note that each li tag represents a path and in our example has three paths hence three li tag's. Also note that each li tag has a aura:id attribute. We will use this in javascript to mark a path as complete or incomplete

Now, let's add some coloring and change the current path to orange. We will also change the complete path to gray.

Add the following CSS code to 'lightningPathExample.css'

Use Case:

Control component visibility on a lightning page. We would like to show a component on a lightning record page only when the user is assigned a specific permission set. We will use custom permissions to achieve this.

What is custom permissions?

Custom permission let you define your own permissions for use within your salesforce environment. You could then assign these permissions to either a permission set or a profile. More details here.

Status transitions:

A most common use case for javascript buttons is a simple field update, onclick of the button a field/fields are updated and the page is refreshed.

With the onset of Lightning javascript buttons are no longer supported and hence have to be replaced. A simple solution would be to use Visualforce which works both in the Lightning UI and classic. However, there is a known issue where the page does not reload/get the updated information when you a do a page redirect using PageReference in Visualforce.

Know Issue: https://success.salesforce.com/issues_view?id=a1p3A0000001C8QQAU&title=data-not-updated-in-ui-after-an-apex-update-in-lightning-experience

I hope the issue gets fixed soon. In the meanwhile, here is a code snippet to replicate the same functionality using lightning components.

LIGHTNING:

Under Buttons, Links and Actions for the object create a new action and link it to the lightning component created above.

CLASSIC:

Use Visualforce or a simple Visual Flow to replicate the field update behavior in classic. Here is a link to get you started with Flows

There is a known issue when customers are unable to post comments through the community.

While the workaround mentioned does address the issue, it should be noted that any email templates associated should be taken care. Make sure you check these areas and move all associated email templates into a public folder.

• Workflow rules and workflow email alerts.
• Process builder and associated email alerts.
• Email templates specified under support settings (Image below)
  

Purpose:

This article will pre-populate a default email template when the user clicks the 'Email' action on case feed layout, or clicks the 'Reply' / 'Reply All' button.

Apex Class:

You will need an Apex Class which implements the QuickActions.QuickActionsDefaultHandler

Please note that you could use the class below to modify the code and pick different templates for different scenarios.

Update Support Settings:

 

Screenshot:

There are quite a few ways content (files) are stored in Salesforce. This article shows you ways to access them through a SOQL query.

EMAIL ATTACHMENT:

Let's consider the scenario where we have attachments against email messages related to a Case. Let's see how to query it in SOQL.

SOQL Query:
 Assuming case number 123

Case cs = [Select Id from Case where CaseNumber=123];
Map<Id,EmailMessage> caseEmails = new Map<Id,EmailMessage>([Select Id from EmailMessage where ParentId=:cs.Id and HasAttachment = true]);
Set<Id> caseRelatedIds = new Set<Id>();
if(caseEmails != null){
     caseRelatedIds.addAll(caseEmails.keySet());
}
List<Attachment> AttachedFiles = [SELECT Id, Name, Body, ContentType FROM Attachment WHERE ParentId IN :caseRelatedIds];

ATTACHMENTS against a Case:

Case cs = [Select Id from Case where CaseNumber=123];
List<Attachment> AttachedFiles = [SELECT Id, Name, Body, ContentType FROM Attachment WHERE ParentId IN =:cs.Id];

Salesforce Files Attached to a Case Feed:

Case cs = [Select Id from Case where CaseNumber=123];
List<CaseFeed> caseChatterFiles = [SELECT Id, Type, Body, Title, LinkUrl, ContentData, ContentSize, ContentFileName, ContentType From CaseFeed where Type = 'ContentPost' and parentId = :cs.Id];

When your delegated authentication fails, you are presented with the error message as in this article title. Below are a few steps to troubleshoot when you face such a issue.

Verify that your internal server hosting the authentication service is up and running. You can identify the server by checking the SSO page under setup.


Do you whitelist Salesforce IP's access to your internal server? If yes, check this page to make sure no new IP's were added to the list.

Check the Delegated Authentication Error section under setup.

















If you see an error message as below, make sure the certificates are updated on your internal server. Here is an article with more details and list of certificates approved by Salesforce - Click here

javax.net.ssl.SSLPeerUnverifiedException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

 

Note: Salesforce has a standard VLOOKUP function but has limited functionality, this approach helps overcome those without code.

Process Builder and Flows are recent automation engines provided by Salesforce, they have been around for a while but haven't been used widely i believe (probably developers tend to stick with Apex Triggers and Workflow rules as they are used to it)

The use case below shows you how you could use these two together to solve a simple scenario which as a developer we tend to solve with Apex Code.

Scenario:

Everytime a Product2 record is updated, i have to query if this product exists in a custom object (Exempted parts) and based on the result update a boolean field on Product2.

Solution:

STEP 1:

Create a Flow (Product2_Validate_Exemption)

STEP 2:

Create a Process and call the flow every time a product2 record is updated.

Reference: This example uses the great search component provided by Avinava Maiti. His blog is here 
http://blogforce9.blogspot.com/

Problem:

Using a standard lookup field on the user object, Salesforce does not allow you to lookup a user who is of the license type 'Chatter Free'.

Solution:

Although you cannot use a standard UI to update the user lookup field with a chatter free user, you can update the field through the API. This means that we could use a visualforce page to populate the lookup field.

Assumptions:
We will use a custom type ahead advanced search component.
We will use a custom field 'Chatter Free user lookup' on the account object.

STEP 1:
Install the autocomplete search component from here

http://blogforce9dev-developer-edition.ap1.force.com/ProjectDetail?id=a0290000009KusM


STEP 2:

Create the following apex class


STEP 3: Create the following visualforce page:democustomlookup

STEP 4: Create a new custom button on the account object.
STEP 5:

Add this custom button to the page layout and you are done.

RESULT:

Lightning Experience / Lightning UI:

• Lightning Experience can be turned ON at the profile level, or for individual users using permission sets.
• ALL standard profiles are lightning UI enabled by default, when you enable Lightning UI for your organization. [Workaround: Replace standard profiles with custom profiles]
• Visualforce pages work as usual in the lightning UI, however you might want to do a sanity check to make sure nothing is broken.
• Visualforce pages open with the old look and feel. The old look and feel is referred to as Salesforce Classic.

Lightning Design System:

Lightning Design system is a front end framework for developing web applications. Using the Lightning Design system you could design visualforce pages or standalone web pages that look and feel the same way as the Lightning UI. A few pointers.

• Lightning Design system could be though of as an equivalent to 'Twitter Bootstrap'.
• To download and start using visit https://www.lightningdesignsystem.com/
• The design system is purely made up of CSS files.
• The design system comes with pre-built components such as pop-up modals, tree structure, buttons etc.
• Lightning Design system focuses mainly on the front end. Data manipulation and processing will still be done using Apex and Visualforce/other desired markup language.

Lightning App Builder:

The Lightning App builder is a drag and drop tool to build lightning pages. Salesforce offers a few components by default, including 'Recent Items', 'Assistant', 'List View' etc. In addition you can create your own custom components using the Lightning Design system, or use third party components supplied by AppExchange applications like SKuid
