Returning an ArrayList back to Freemarker

[bengrah]

Hi guys,

I've wrote a Java-backed webscript that's returning an ArrayList<String> collection which I can easily print on screen in the freemarker template

<#list list as children>
${children}
</#list>

What I want to do is return an ArrayList of NodeRefs, so that way I can reference properties of nodes on the Freemarker side. So here's my code

…
unlockedFilesArray.add(row.getNodeRef());
model.put("unlockedNodes", unlockedFilesArray);
return model;
…
‍‍‍‍‍‍‍

Then in the Freemarker template:

<#list unlockedNodes as children>
${children.properties["cm:name"]}
</#list>

But this throws an error:

freemarker.template.TemplateException: Expected hash. child evaluated instead to freemarker.template.SimpleScalar on line 10, column 55 in org/example/javadir.get.html.ftl.
‍‍‍

I'm sure the problem lies with the reference to the ArrayList or the syntax I'm using. Any ideas?

Thanks,
Ben.

Hello,

the error does not appear to relate to the Freemarker Snippet you've provided. Somehwere in your template you are accessing a variable "child" where the object referenced by that variable is not a hash (object / map). If you can provide more of your template, we might be able to point it out to you - otherwise, the error already states the line and column of the incorrectly access variable.
