[jira] [Commented] (FREEMARKER-12) #return value bubbles through functions

["Daniel Dekany (JIRA)" <ji...@apache.org>]

Daniel Dekany commented on FREEMARKER-12:
-----------------------------------------

While this would be trivial to fix, it can't be fixed as that breaks backward compatibility. I'm afraid this will require the {{incompatibleImprovements}} configuration setting to be set to 2.4.0, hence the fix can't be present in the 2.3.x series.

>          Issue Type: Bug
>    Affects Versions: 2.3.23
>            Reporter: Diogo Kollross

> The documentation says that "if ... there was no 'return returnValue', then the return value of the method is an undefined variable", but the behaviour I'm seeing is that any #return in inner method calls gets returned as if it was the caller's return value.
> In the following example the expected result is an undefined value, but it shows "inner value".
> {noformat}
> <#function inner>
>   <#return "inner value">
> </#function>
> <#function example>
>   <#local temp = inner()>
> </#function>
> ${example()}
> {noformat}
