Subject: [FreeMarker-user] Handling null objects


I haven't found in the doc how to handle the null objects.

I load from the database a user by its id, but it may happen that doesn't
exist. In that case, the "user" variable will be null.

I wanted to evaluate it in a if:

<#if user == null>
	New User
<#else>
	Editing <em>${user.name}</em>
</#if>

But I get this error:

Expression null is undefined


How should I evaluate that object?
