Handling null values in Freemarker

Question

How to handle null values in Freemarker? I get some exceptions in the template when null values are present in data.

Answer 1

Use ?? operator at the end of your <#if> statement.

This example demonstrates how to handle null values for two lists in a Freemaker template.

List of cars:
<#if cars??>
    <#list cars as car>${car.owner};

List of motocycles:
<#if motocycles??>
    <#list motocycles as motocycle>${motocycle.owner};
