TemplatedResource binding to Resource

[venkiiitk]

Hi,

In what scenarios  below code can inject TemplatedResourceImpl  Instead of JcrNodeResouce Object 

@inject
protected Resource resource;

we have upgraded from AEM 6.4 to 6.5 latest SP and seeing this kind of issue. 

Thanks,

Venkat

Hi @venkiiitk,

TemplatedResourceImpl is generally injected when a resource is resolved in the context of editable templates. If the resource being requested is wrapped due to editable template logic, AEM may adapt it to TemplatedResourceImpl.

I tested it on my page created by Editable Template (/conf/myproject/settings/wcm/templates/blank-page/structure/jcr:content/root/container). Below you can find my editable template as example and screenshot from the debugger:

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
    jcr:primaryType="cq:Page">
    <jcr:content
        cq:template="/conf/myproject/settings/wcm/templates/content-page"
        jcr:primaryType="cq:PageContent"
        sling:resourceType="myproject/components/page">
        <root
            jcr:primaryType="nt:unstructured"
            sling:resourceType="myproject/components/container"
            layout="responsiveGrid">
            <container
                jcr:primaryType="nt:unstructured"
                sling:resourceType="myproject/components/container"
                editable="{Boolean}true"
                layout="responsiveGrid"/>
        </root>
    </jcr:content>
</jcr:root>

Here you can see a proof:

Hi konstantyn_diachenko,

Thanks for the reply and interesting. 

Let me explain our issue little bit more detailed.

we are using same template and same Core Image component before and after upgrade from 6.4 to 6.5.

In 6.4, Resource resolving to JcrNodeResouce and in 6.5 Resolving to TemplatedResource and in AEM core image component we have some logic like this : 

Resource file = resource.getChild(DownloadResource.NN_FILE);
if (file != null) {
mimeType = PropertiesUtil.toString(file.getResourceMetadata().get(ResourceMetadata.CONTENT_TYPE), MIME_TYPE_IMAGE_JPEG);
hasContent = true;
} 

So that means, it should fail in both versions and also another observation is , when i verify same in New 6.5 instance then again getting JcrNodeResouce when i use image component under we retail Men pag. 

So not sure what happened as part of In-place upgrade. 

Thanks,

Venkat

Hi @venkiiitk,

Could you please provide more details about your editable template structure and content structure?

Okay, this image resource is not a part of structure. What core components version do you use? How do you use your Sling model or is it Core Component Model? What is the path to image resource?

[venkiiitk]

Hi,

it is AEM core Image V2 component and version is 2.2.2

and image path like this : /content/we-retail/us/en/demo/jcr:content/root/responsivegrid/image/file/jcr:content 

Attached like image file and it is trying to resolve extension and due to TemplatedResource , it is returning default JPEG extension.

Thanks,

Venkat

Hi, 

I see that 2.2.2 version of Core Components is not compatible with AEM 6.5: https://github.com/adobe/aem-core-wcm-components/blob/main/VERSIONS.md Could you please try to install latest compatible version on Core Components and test with it?

I tried to put image in the same location for page created with an editable template. ImageImpl model injected TemplatedResource as well and rendered image with correct extension. I think you need to update Core Components version according to your AEM version.
