Folder Schema missing for Assets

Here is a sample AEM fiddle script to add foldermetadataschema to subfolders programatically

package apps.acs_002dtools.components.aemfiddle.fiddle;

import com.day.cq.wcm.api.*;

import com.day.cq.dam.api.*;

import java.util.*;

public class fiddle extends SlingAllMethodsServlet {

    @Override

    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws IOException {

          // Code here

        //response.getWriter().println("Hello from " + request.getResource().getPath());

        Resource resource = request.getResourceResolver().getResource("/content/dam/AEM63App");

Resource res = request.getResourceResolver().getResource(resource.getPath()+"/jcr:content");

ValueMap properties = res.adaptTo(ValueMap.class);

String metaDataSchemaValue = properties.get("folderMetadataSchema", String.class);

response.getWriter().write(""+metaDataSchemaValue);

Session session =  request.getResourceResolver().adaptTo(Session.class);

        if (resource != null) {

           if (resource != null) {

Iterator<Resource> linkResources = resource.listChildren();

while (linkResources.hasNext()) {

Resource childResource = linkResources.next();

try{

Node childNode = childResource.adaptTo(Node.class);

childNode = childNode.getNode("jcr:content");

childNode.setProperty("folderMetadataSchema",metaDataSchemaValue);

session.save();

response.getWriter().write(""+childNode.getProperty("jcr:title").getString());

}catch(RepositoryException re){}

}

}

            response.setStatus(SlingHttpServletResponse.SC_OK);

        } else {

            response.setStatus(SlingHttpServletResponse.SC_INTERNAL_SERVER_ERROR);

            response.getWriter().write("ERROR");

        }

    }

    }
