Show pages of specific resourceType in pathfield selection dialog

[FotisMa1]

Hello everyone,

I have recently run into an issue where I want to filter the pages that appear inside of a pathfield's selection dialog, to pages that have a specific resourceType (e.g. "products"). I have tried using a custom predicate to achieve this, but it does not seem to work (predicate gets registered as an OSGi service, but never fires).

Could anybody shine some light on this? Is a predicate even the correct way of approaching this? I will attach the code bellow nonetheless. We are using AEM as a Cloud Service.

Thanks in advance!

Predicate:

// Imports omitted

@Component(
    service = Predicate.class,
    property = { "predicate.name=allowed-article-predicate" }
)
public class AllowedArticlePredicate extends AbstractNodePredicate {

    private static final Logger log = LoggerFactory.getLogger(AllowedArticlePredicate.class);

    private static final String[] ALLOWED_RESOURCE_TYPES = {
        CommonConstants.NEWS_RESOURCE_TYPE,
        CommonConstants.EVENT_RESOURCE_TYPE,
        CommonConstants.PRODUCT_RESOURCE_TYPE
    };

    @Override
    public final boolean evaluate(final Node node) {
        if (Objects.nonNull(node)) {
            try {
                if (node.isNodeType("cq:Page")) {
                    Node contentNode = node.getNode("jcr:content");
                    if (contentNode != null && contentNode.hasProperty("sling:resourceType")) {
                        String resourceType = contentNode.getProperty("sling:resourceType").getString();
                        for (String allowedType : ALLOWED_RESOURCE_TYPES) {
                            if (allowedType.equals(resourceType)) {
                                return true;
                            }
                        }
                    }
                }
            } catch (RepositoryException re) {
                log.error("Unable to read node or property: {}", re.getMessage());
            }
        }
        return false;
    }
}

CQ Dialog:

<article
      jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/form/pathfield"
      fieldLabel="Article Selection"
      name="./article"
      required="true"
      showTitleInTree="true"
      predicate="allowed-article-predicate"
      multiple="false"
      forceSelection="{Boolean}true"
/>

Hi @FotisMa1 

Custom Java predicates don't work in AEM as a Cloud Service with Touch UI `pathfield`. They were supported in Classic UI or older AEM versions but are ignored now. Touch UI only supports predefined client-side filters—no custom OSGi predicate injection.

To filter pathfield options by sling:resourceType in AEM as a Cloud Service, custom Java predicates will not work.

1.Use autocomplete in the dialog:

<article
    jcr:primaryType="nt:unstructured"
    sling:resourceType="granite/ui/components/coral/foundation/form/autocomplete"
    fieldLabel="Select Product Page"
    name="./article"
    multiple="{Boolean}false"
    required="{Boolean}true">
    
    <datasource
        jcr:primaryType="nt:unstructured"
        sling:resourceType="myproject/components/datasource/productpages" />
</article>

2.Create a DataSource Servlet to return pages with specific sling:resourceType:

@Component(service = Servlet.class,
    property = {
        "sling.servlet.resourceTypes=myproject/components/datasource/productpages",
        "sling.servlet.methods=GET"
    })
public class ProductPagesDataSourceServlet extends SlingSafeMethodsServlet {
    @Override
    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response)
            throws ServletException, IOException {
        ResourceResolver resolver = request.getResourceResolver();
        List<Resource> options = new ArrayList<>();

        String query = "SELECT * FROM [cq:PageContent] AS pageContent "
                     + "WHERE pageContent.[sling:resourceType] = 'myapp/components/page/product'";

        Iterator<Resource> results = resolver.findResources(query, Query.JCR_SQL2);
        results.forEachRemaining(res -> {
            String title = res.getValueMap().get("jcr:title", res.getName());
            String path = res.getParent().getPath(); // Get the page path
            ValueMap vm = new ValueMapDecorator(new HashMap<>());
            vm.put("text", title);
            vm.put("value", path);
            options.add(new ValueMapResource(resolver, new ResourceMetadata(), "nt:unstructured", vm));
        });

        DataSource ds = new SimpleDataSource(options.iterator());
        request.setAttribute(DataSource.class.getName(), ds);
    }
}

Replace:

myapp/components/page/product with your actual resourceType.

Hope this helpful.:)

Hi @FotisMa1 

I remember using this with pathbrowser field.
