Hi,

I try to migrate my LTS2019 webEngine app to LTS2021 and I have freemarker code problem .

...
<#function get_date doc modified_date
    <#list doc.children as child>
      <#if modified_date.time?datetime == child.dublincore.modified.time?datetime>
          <#local modified_date = child.dublincore.modified>
      </#if>
      <#if doc.isFolder>
          <#local modified_date = get_date(child, modified_date)>
      </#if>
    </#list>
    <#return modified_date>
</#function>
...

When I try to access docuents, I have this exception :

exception_message : For "." left-hand operand: Expected a hash, but this has evaluated to a date_or_time_or_datetime (wrapper: f.t.SimpleDate):
==> modified_date  [in template "file:/var/lib/nuxeo/server/nxserver/web/root.war/modules/nuxeo-utt/skin/views/Document/index.ftl" at line 21, column 22]

How can I workaround this issue ?
