Exception when extending Sightly page component

[salvadorm142499]

Hi all,

Using AEM 6.2, I have created a template /apps/myproject/templates/mytemplate and a page component for that template at /apps/myproject/components/pages/basepage. Set the sling:resourceSuperType of this component to be wcm/foundation/components/page. Create now a page based on this template and it throws an exception:

org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.sightly.SightlyException: org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.sightly.SightlyException: Identifier com.day.cq.wcm.foundation.TemplatedContainer cannot be correctly instantiated by the Use API

The issue appears at body.html when using the Java USE Api at <sly data-sly-use.body="body.js" data-sly-use.templatedContainer="com.day.cq.wcm.foundation.TemplatedContainer"/>

Which is the purpose of templatedContainer object? Why is it throwing the exception? I can not find the source code of TemplatedContainer Java class :(

Cheers,

Salva.

If you want to use a Sightly page component - try using the one built for you when you use Maven 10. See: 

https://helpx.adobe.com/experience-manager/using/first-arch10.html

Use that one as a starting point.

Hi Salva,

As per scott stated, you can use default Sightly Page component using Maven 10 archetype plugin.

See this article which creates the AEM project on maven archetype 10 plugin: https://helpx.adobe.com/experience-manager/using/first-arch10.html - This includes default Sightly page component.

Hope this helps!

Thanks,
Ratna Kumar.

Hi,

Do refer to the documentation of this class @ https://docs.adobe.com/docs/en/aem/6-2/develop/ref/javadoc/com/day/cq/wcm/foundation/TemplatedContai...

templatedContainer will help you to get access the method of this class which I feel are

             

String	getNewResourceType()
List<Resource>	getStructureResources()

try this

 <div data-sly-use.templatedContainer="com.day.cq.wcm.foundation.TemplatedContainer">

        ${templatedContainer.newResourceType}

</div>

It looks like you are using data-sly-use attribute multiple times in a single <sly> tag. Also try using "data-sly-use" in <div> tag instead of <sly> tag.

Hi bsloki,

I think it is possible. Moreover, the sightly page component under foundation contains two data-sly-use in a single <sly> tag.

Hi edubey,

The issue appears when the object is instantiated instead of when the object calls its methods... still throwing exceptions.

Hi smacdonald,

This answer does not really solve my problem as I can not use the capabilities of the 'TemplatedContainer' object but, It works :)

Cheers,

Salva.
