Template examples and FreeMarker

fouellet — Thu, 01 Dec 2005 17:34:18 GMT

I was trying the template samples and got errors with the <#list> directive while trying to product a list of objects. I am new to FreeMarker, but it seems that the variable assigned with "as" cannot be used… For example, even simple stuff like: <#list ["one", "two", "three"] as n> ${n}

Hello,

I tried the simple template code you mentioned:

<#list ["one", "two", "three"] as n>
${n}
</#list>

and it worked just fine. We are using much more complex templates than this without any problems.

Can you tell me more about your setup?

Thanks,

Kevin

I am using the RC1 distribution for Tomcat on Fedora Core 3, all plain vanilla settings. The only customizations made were a few language packs, everything else is original.

I am not sure where to look, it seems like a variable scoping or namespace issue. I tried using the global directive but the variables don't seem to "stay" in the namespace after they get created. I can get all the values from the repository objects, but cannot use variables of my own. The ftl file is in the repository, as a Content Template. I did not try using an outside file.

CLASSPATH is defined as /opt/alfresco/tomcat/webapps/alfresco/WEB-INF/lib

Here is the complete output:

===========================

<#list ["one", "two", "three"] as n>

Expression n is undefined on line 1, column 283 in workspace://SpacesStore/c12bdd80-5546-11da-9a4d-db39df59542d.

The problematic instruction:
