I have the problem that I am not able to reference document type custom metadata fields.

In Content -> Documents and Media I have defined a new document type (eg MIO) with two metadata fields (eg MIOUsage and MIONotes).

In an asset publisher that displays only MIO document type I was able to define an ADT that displays Name, description and small image; but Iwas not able to reference the two custom fields.

I tried
${assetRenderer.getMiousage()!"xxx"}

which gives an "evaluated to null or missing" error

and
${entry.getMiousage()!"xxx"}

which gives the same error

How can I refer to metadata fields defined for a document type?

One step ahead.
Inserting this code in ADT

<#assign className = assetRenderer.getClassName()!"x" />
<#if className == "com.liferay.document.library.kernel.model.DLFileEntry">

<#assign metaf = stringUtil.split(metadataFields) !"x" />
<#list metaf as metaf1>
    ${metaf1}
<!--#list-->

        <!--#if-->


I can list the metadata thea are enabled in the Asset Publisher configuration

The document is a DLFile so I changed the thread title

Still I don't know how to reference the custom data.

Seems I have to use DLFileEntryLocalServiceUtil but I don't know how

I've found an old article at http://platinumbed-liferay.blogspot.ch/2014/12/application-display-template-documents.html

I've put 
freemarker.engine.restricted.variables=

in portal.properties. Then tried this code:

&lt;#if entries?has_content&gt;
	&lt;#list entries as curEntry&gt;
		${curEntry.getTitle(locale)}
&lt;#assign dlFileEntryService = serviceLocator.findService("com.liferay.portlet.documentlibrary.service.DLFileEntryLocalService")&gt;
<hr>
	<!--#list-->
<!--#if-->


But I receive the error that serviceLocator is not found

The following has evaluated to null or missing:
==&gt; serviceLocator  [in template "20116#20160#66884" at line 5, column 31]


Anyone knows how to manage this error?

A little step ahead.
Trying to follow the instructions at http://platinumbed-liferay.blogspot.it/2014/12/application-display-template-documents.html (that is for LR 6)
and https://web.liferay.com/it/community/forums/-/message_boards/message/73391506?_19_threadView=flat (to enable serviceLocator)

I came up with this adt:
&lt;#if entries?has_content&gt;
	&lt;#list entries as entry&gt;
        &lt;#assign curFileEntry = entry /&gt;
        &lt;#assign assetRenderer = curFileEntry.getAssetRenderer() /&gt;
        &lt;#assign className = assetRenderer.getClassName()!"x" /&gt;
        &lt;#if className == "com.liferay.document.library.kernel.model.DLFileEntry"&gt;
            &lt;#assign dlFileEntryService = serviceLocator.findService("com.liferay.document.library.kernel.service.DLFileEntryLocalService")&gt;
            ${dlFileEntryService  }<br>
            &lt;#assign xx = curFileEntry.getFileEntryId() &gt;
            &lt;#assign dlFileEntry = dlFileEntryService.getFileEntry(xx)&gt;
        <!--#if-->
	<!--#list-->
<!--#if-->


This gives the error
The following has evaluated to null or missing:
==&gt; curFileEntry.getFileEntryId  [in template "20116#20160#66884" at line 9, column 27]

on getFileEntryId

Any hint on how to convert the code in the blog to LR 7?

Another step ahead.

Now the problem is that entry.getExpandoBridge.getAttributeNames() returns an empty string

Here the code I used in the Asset Publisher ADT for a document type called "MIO" with two custom field: MIOUsage and MIONotes.

The code:
&lt;#if entries?has_content&gt;
	&lt;#list entries as entry&gt;
        &lt;#assign assetRenderer = entry.getAssetRenderer() /&gt;
        &lt;#assign entryTitle = htmlUtil.escape(assetRenderer.getTitle(locale)) /&gt;
        TITLE: ${entryTitle} <br>
        &lt;#assign className = assetRenderer.getClassName()!"x" /&gt;
        CLASSNAME: ${className} <br>
        &lt;#if className == "com.liferay.document.library.kernel.model.DLFileEntry"&gt;
            &lt;#assign myyy = entry.getExpandoBridge() /&gt;
            EXPANDOBRIDGE: ${myyy.toString()} <br>
            &lt;#assign yyy = myyy.getAttributeNames() /&gt;
            LIST ATTRIBUTES: ${yyy.toString() } <br>
            &lt;#list yyy&gt;
                &lt;#items as y&gt;
                    NAME ATTRIBUTE: ${y} <br>
                <!--#items-->
            &lt;#else&gt;
                THERE ARE NO ATTRIBUTE NAMES <br>
            <!--#list-->
            &lt;#assign xxx = myyy.getAttribute("	MIOUsage",false) !"FIELD NOT FOUND" /&gt;
            EXPANDOBRIDGE: MIOUsage-fieldname value = ${xxx} <br>
            &lt;#assign xxxl = myyy.getAttribute("	Usage",false) !"FIELD NOT FOUND" /&gt;
            EXPANDOBRIDGE: MIOUsage-label value = ${xxxl} <br>
        &lt;#else&gt;
            It is NOT a DLFileEntry
        <!--#if-->
        <hr>
	<!--#list-->
<!--#if-->


The result for an enty with all fields filled:
TITLE: a_few_oh_sht_situations_640_27.jpg
CLASSNAME: com.liferay.document.library.kernel.model.DLFileEntry
EXPANDOBRIDGE: com.liferay.portlet.expando.model.impl.ExpandoBridgeImpl@aa725
LIST ATTRIBUTES: java.util.Collections$3@3a4ee3aa
THERE ARE NO ATTRIBUTE NAMES
EXPANDOBRIDGE: MIOUsage-fieldname value = FIELD NOT FOUND
EXPANDOBRIDGE: MIOUsage-label value = FIELD NOT FOUND


I tried to get field names and it returns an empty list.
I tried to access the fields with getAttribute using the field name or the field label: nothing is returned

How can I use getExpandoBridge.getAttributeNames() to get the attibute names?
