EmailTemplateSelector Interface

The Support.EmailTemplateSelector interface enables providing default email templates in Case Feed. With default email templates, specified email templates are preloaded for cases based on criteria such as case origin or subject.

Namespace

Support

To specify default templates, you must create a class that implements Support.EmailTemplateSelector.

When you implement this interface, provide an empty parameterless constructor.

EmailTemplateSelector Methods

The following are methods for EmailTemplateSelector.

getDefaultTemplateId(caseId)

Returns the ID of the email template to preload for the case currently being viewed in the case feed using the specified case ID.

Signature

public ID getDefaultTemplateId(ID caseId)

Parameters

caseId: Type: ID

Return Value

Type: ID

EmailTemplateSelector Example Implementation

This is an example implementation of the Support.EmailTemplateSelector interface.

The getDefaultEmailTemplateId method implementation retrieves the subject and description of the case corresponding to the specified case ID. Next, it selects an email template based on the case subject and returns the email template ID.

1swfobject.registerObject("clippy.codeblock-0", "9");

22    global ID getDefaultEmailTemplateId(ID caseId) {
23        // Select the case we're interested in, choosing any fields that are relevant to our decision
24        Case c = [SELECT Subject, Description FROM Case WHERE Id=:caseId];
25
26        EmailTemplate et;
27
28        if (c.subject.contains('LX-1150')) {
29            et = [SELECT id FROM EmailTemplate WHERE DeveloperName = 'LX1150_template'];
30        } else if(c.subject.contains('LX-1220')) {
31            et = [SELECT id FROM EmailTemplate WHERE DeveloperName = 'LX1220_template'];
32        } 
33        
34        // Return the ID of the template selected
35        return et.id;
36    }
