Matt, That seems to have been the issue. I am surprised that it was null, since I had converted the same method to return a String, and everything was working (and displaying content).

To test my hypothesis, try adding the default value operator (the ! character) after your collection, thus replacing xxx?size with xxx!?size and see if it still throws the exception. If it doesn't then there's a good chance that your collection is null. For more info on this and different approaches to handling null objects, check out the documentation for the has_content built-in here: http://freemarker.sourceforge.net/docs/ref_builtins_expert.html#ref_builtin_ has_content You can also have a look at handling missing values and the default value operator documentation here: http://freemarker.sourceforge.net/docs/dgui_template_exp.html#dgui_template_ exp_missing HTH, Matt From: Jan Haderka <[email protected]> Reply-To: Magnolia User-List <[email protected]> Date: Wed, 30 Jun 2010 16:45:49 +0200 To: Magnolia User-List <[email protected]> Subject: Re: [magnolia-user] Use standard FTL directives on page? You should be able to iterate over the list just fine in freemarker. You might want to check their documentation if you are not sure about the syntax. If you are sure that the syntax is fine, please postthe snippet of the code causing the problem and full exception message and stacktrace to pastebin.com <http://pastebin.com> or similar service and post here the link to it.
