Syntax

Default(Value)

The Default(Value) function syntax is as follows:

• If the input data of the Default function is either null or undefined, this function returns the value of its argument.

• If the input data of the Default function is neither null nor undefined, this function returns its input data.

Examples

If you want to look up a custom object by Account.Locale__c to implement globalization, you can use the following function example:

{{Cmd_ListToDict(default__messages|FilterByRef(locale__c,EQ,Invoice.Account.Locale__c),key__c,value__c,Message)}}

The preceding function example uses FilterByRef(locale__c,EQ,Invoice.Account.Locale__c) to dynamically filter custom object records by an account custom field. However, if no account custom field is defined, the preceding function example returns empty in the rendered result.

In this case, you can append a Default function that uses a default value en_US in case the account custom field is undefined and the Account.Locale__c field is empty. The function example can be as follows:

{{Cmd_ListToDict(default__messages|FilterByRef(locale__c,EQ,Invoice.Account.Locale__c|Default(en__US)),key__c,value__c,Message)}

If the Account.Locale__c field is undefined, the preceding function example returns en_US in the rendered result.
