Is it possible to access pageProperties from a datasource?

[alvarof55440963]

Hi folks. Hope you are doing great.

So this is my problem. I need to dynamically load the options for a select item in a component dialog based on a page property. So I was planning to create a datasource that would read the page properties and then set the select options based on the value of the property. The problem is that if I try to access pageProperties or currentPage it is always null.

Is there a way to actually read page properties from a datasource?

I have my select in the component dialog like this:

<options
           jcr:primaryType="nt:unstructured"
           sling:resourceType="granite/ui/components/coral/foundation/form/select"
           fieldLabel="Options"
           name="./options">
           <datasource
                  jcr:primaryType="nt:unstructured"
                  sling:resourceType="examples/datasources/test"/>
</options>

And my datasource:

<%@page session="false" import="
                  com.day.cq.commons.inherit.HierarchyNodeInheritanceValueMap,
                  com.day.cq.commons.inherit.InheritanceValueMap,
                  com.adobe.granite.ui.components.ds.DataSource,
                  com.adobe.granite.ui.components.ds.EmptyDataSource,
                  com.adobe.granite.ui.components.ds.SimpleDataSource,
                  com.adobe.granite.ui.components.ds.ValueMapResource,
                  org.apache.sling.api.resource.Resource,
                  org.apache.sling.api.resource.ResourceMetadata,
                  org.apache.sling.api.resource.ResourceResolver,
                  org.apache.sling.api.resource.ValueMap,
                  org.apache.sling.api.wrappers.ValueMapDecorator,
                  java.util.ArrayList,
                  java.util.HashMap,
                  java.util.Iterator,
                  java.util.List"%>
<%
%><%@taglib prefix="cq" uri="http://www.day.com/taglibs/cq/1.0" %><%
%><cq:defineObjects/><%
     //pageProperties always null here 
%>

I'm using AEM 6.4

Thanks

I would use Java and HTL. You can read the page props using Page Manager API.

Using a Page object - you can obtain a lot of information about a given page.

Page ("The Adobe AEM Quickstart and Web Application.")

Then you can put that into a MAP on which a DataSource is based.

See this to learn how to use Java to create a DataSource to populate a Select:

Hi,

You can get the Page Property by getting page path and adapt to Node

Example :

  ResourceResolver resolver = request.getResourceResolver();

  String pagePath = request.getRequestPathInfo().getSuffix().replaceAll("/jcr:content/.*$", "");

  Node pageNode = resolver.getResource(pagePath).adaptTo(Node.class);

  String pageTitle= pageNode.getProperty("jcr:title").getString();
