Daniel Dekany commented on FREEMARKER-21:
-----------------------------------------
Yeah, it's familiar... I guess it should be {{<#if
(someVariable.someMethod.someProperty as value)??>}}, because then the
condition can be arbitrary, like {{<#if (x.y as value).z + u != 0>}}.
> Reference to the object in condition - avoid repeating the same in #if and
> ${...}

> Key: FREEMARKER-21
> URL: https://issues.apache.org/jira/browse/FREEMARKER-21
> Project: Apache Freemarker
> Issue Type: New Feature
> Components: engine
> Reporter: Ondra Žižka
> Fix For: 2.3.23
>
>
> Repeating stuff is annoying, especially in programming.
> Therefore this is annoying:
> {code}
> <#if someVariable.someMethod.someProperty??>
> <div>${someVariable.someMethod.someProperty}</div>
> </#if>
> {code}
> This would be better:
> {code}
> <#if someVariable.someMethod.someProperty?? as value>
> <div>${value}</div>
> </#if>
> {code}
> Not talking about the fact that it could only be evaluated once.
