RE: Get Web Content Structure image values inside an ADT

I guess, the easiest way is to use eval. Try this:
<#assign
data = posterImage?eval
fileEntryId = data.fileEntryId
/>

Get Web Content Structure image values inside an ADT

2019-04-12T17:57:53Z

I am making an Application Display Template that shows different types of Web Content Articles (different Structures). All of the Structures have a field called "PosterImage" (image type).

I am able to get a reference to the image with code like this in the ADT:

&lt;#assign
&nbsp; className = assetRenderer.getClassName()
&nbsp; article = assetRenderer.getArticle()
&nbsp; document = saxReaderUtil.read(article.getContent())
&nbsp; rootElement = document.getRootElement()
/&gt;

&lt;#list rootElement.elements() as dynamicElement&gt;
&nbsp; &lt;#if "PosterImage" == dynamicElement.attributeValue("name")&gt;
&nbsp;   &lt;#assign posterImage = dynamicElement.element("dynamic-content").getData() /&gt;
  <!--#if-->
<!--#list-->

The value of posterImage looks like key/value pairs:

{"groupId":"20126","name":"handshake_0.jpg","alt":"","resourcePrimeKey":"","title":"handshake_0.jpg","type":"journal","uuid":"f02ca676-f6ed-471a-a56c-e9d083b010ac","fileEntryId":"142301","resourcePrimKey":"142311"}

But it seems to be a string (posterImage?is_string?c outputs true, posterImage?is_hash?c outputs false). How can I get these as discrete values, to assign them to Freemarker variables? In this case, I am only interested in the fileEntryId value.
