Error getting a templated email containing @extends to send.

Essentially, when I make a base template for emails and I try to extend it using @extends..., I get the following error when Nuxeo should send email :

10:56:25,864 ERROR [runtime] 

on line 1, column 1 in modif extends not found.
The problematic instruction:
----------
==> user-directive extends [on line 1, column 1 in modif]
----------

Java backtrace for programmers:
----------

I've read that this seems to be that it can't find the file I'm referring to, which is in the same directory.

I then tried to deploy it to nxserver/nuxeo.war/skin/, which also fails with the same error.

Is it really a file location issue?

To me it sounds like a parser error, as if it didn't know what to do with the @extends directive.

How does your mail template look like ?

baseNotificationTemplate.ftl :

&lt;html&gt;
&lt;body&gt;
&lt;p&gt;
&lt;@block name=&quot;notif_text&quot;&gt;
Une notification a été envoyée pour le document &lt;b&gt;${htmlEscape(docTitle)}&lt;/b&gt;.
&lt;/@block&gt;
&lt;/p&gt;
&lt;/body&gt;
&lt;/html&gt;

modif.ftl :

&lt;@extends src=&quot;baseNotificationTemplate.ftl&quot;&gt;
        &lt;@block name=&quot;notif_text&quot;&gt;
        Le document &lt;b&gt;${htmlEscape(docTitle)}&lt;/b&gt; a été modifié dans Nuxeo.
        &lt;/@block&gt;
&lt;/@extends&gt;

This is obviously a simplified version, but this example still fails. In this case, the reason for the templating is that we want sane defaults for the blocks. But it doesn't even get to a block, it just fails at the first character on the first line…

I guess it's because the <@extends> directive is not available in the ftl rendering engine of the notification service. It will only work in a WebEngine ftl rendering engine. We obviously need to refactor the old notification service…
