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

You can use the ?? test operator:

This checks if the attribute of the object is not null:

<#if object.attribute??></#if>

This checks if object or attribute is not null:

<#if (object.attribute)??></#if>
