Usage of Tiles 2 Velocity tags for attribute lists

[Xabier Burgos Gimeno]

Hi Everyone!,

First of all let me express my most sincere gratitude to all the developers and 
contributors to the Tiles project, it's a great tool. Now the questions; I've 
been trying to use tiles attribute lists with velocity but so far no luck. I've 
looked for information on this particular topic and It seems the documentation 
on how to use the tiles 2 velocity tags is a bit scarce.

I have this declaration in the template definition file:

<put-list-attribute name="metaKeywords">
    <add-attribute value="keyword1" type="velocity"/>
    <add-attribute value="keyword2" type="velocity"/>
    <add-attribute value="keyword3" type="velocity"/>
    <add-attribute value="keyword4" type="velocity"/>
</put-list-attribute>

And this code in the velocity template file:

<meta name="keywords" content="#foreach($keyword in 
$metaKeywords)$tiles.getAsString({"name":"$keyword"}),#end"/>

But no keyword is printed, neither do I get an error, so, what am I doing wrong?

Thanks in advance,

Xabier Burgos.
