[FreeMarker-user] Invalid Reference Exception while accessing nested map in freemarker

[Sushrut Bidwai]

Hi,

I have nested map.

Map<String, Map<String, Long>> domains;

When I access it in following manner I get InvalidReferenceException

<#list somelist as item>
<#list domains[item]?keys as key>
${key}
</#list>
</#list>

Expression domains[item] is undefined on line...

I tried using BeansWrapper as well as DefaultObjectWrapper. Also I have
checked contents on the map and none of the values are null.

the same question on SO.

How did you add it to the data root?

Hi Dennis,

Map root = new HashMap();
root.put("domains", domains);

Works for me with both DefaultObjectWrapper and BeansWrapper, so I
guess somelist contains some bad keys. But see the same answer on SO
with test code:
