How do I get a selector from a Sling Resource

[kramer2718]

I have two Sling Models:

    @Model(adaptables = {SlingHttpServletRequest.class, Resource.class}, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
    public class VideoGridItem {
      @SlingObject
      private Resource resource;
      @SlingObject
      private SlingHttpServletRequest slingHttpServletRequest;
      @PostConstruct
      public void initVideoGridItem() {
        String[] selectors = slingHttpServletRequest.getRequestPathInfo().getSelectors();
        insideGrid = selectors == null || selectors.length == 0 ? false : Arrays.stream(selectors).anyMatch("grid"::equals);
        url = URLUtils.addHTMLIfPage(resource.getResourceResolver(), linkUrl);
      }
    }

and

    @Model(adaptables = SlingHttpServletRequest.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
    public class VideoListing {
      private List<String> videoResourcePaths;
      @PostConstruct
      final void init() {
      }
    }

I call the VideoGridItem component (technically the resource which references the model) from the video-listing component using HTL:

      <sly data-sly-list.videoResourcePath="${model.videoResourcePaths}">
        <sly data-sly-resource="${videoResourcePath @ wcmmode='disabled', addSelectors='grid'}" data-sly-unwrap="true"></sly>
      </sly>

Now, when I debug the code, inside initVideoGridItem, slingHttpServletRequest is null. Fair enough, this resource isn't being directly requested, but I still need to be able to access the selector "grid". Is there a way I can do this from the VideoGridItem.resource?

Hi,

Same is working for me.

HTL code -

<sly data-sly-resource="${'/content/AEM63App/en/products/help/dialog-even/jcr:content/par/dailogevents' @ wcmmode='disabled', addSelectors='grid'}"></sly> 

Java code -

this.message += "Request Path: " + request.getRequestPathInfo().getResourcePath() + "\n";

  this.message += "Selectors  " + request.getRequestPathInfo().getSelectorString() + "\n";

  String[] selectors = request.getRequestPathInfo().getSelectors(); 

          boolean insideGrid = selectors == null || selectors.length == 0 ? false : Arrays.stream(selectors).anyMatch("grid"::equals); 

  this.message += "inside grid  " + insideGrid + "\n";

Output -
