Exception: Cannot get DefaultSlingScript while dragging component in Editable Templates

[sunitac70336244]

Dear All,

In my current project , we are converting static templates to editable templates in AEM 6.5 SP1 by using modernization_tools

Before converting we are creating editable templates. So I have created editable template and created the policy. Now I want to use the existing component Top Navigation.

While I am using the existing component in my editable template then I am getting below error.

 

*ERROR* [0:0:0:0:0:0:0:1 [1572429882269] GET /conf/sunita/settings/wcm/templates/thank-you/structure/jcr:content/root/topnav1.html HTTP/1.1] com.day.cq.wcm.core.impl.WCMDebugFilter Exception: Cannot get DefaultSlingScript: Identifier com.sunita.global.core.models.SiteUrlsModel cannot be correctly instantiated by the Use API

org.apache.sling.api.SlingException: Cannot get DefaultSlingScript: Identifier com.sunita.global.core.models.SiteUrlsModel cannot be correctly instantiated by the Use API

Can anybody please help me on this?

Thanks in advance

Did you try using the same component on static template?

Its nothing to do with static or dynamic templates its issue with ir sling model class its not available.

check these models through system console.

Dear All and Ka,

By going through some of the AEM forum posts above issue fixed after I changed from @Model(adaptables = SlingHttpServletRequest.class) to @Model(adaptables = Resource.class) .

But now I am getting the below error.

Dear All,

The issue is fixed now. I was getting null pointer exception in my TopNav JAVA class. So changed like below and it is working fine.

if (currentPage != null) {

            Page homePage = currentPage.getAbsoluteParent(SiteConstants.HOMEPAGE_PARENT_DEPTH);           

            if (homePage != null)

            {

            locale = homePage.getLanguage(true);

            }

        }

    }
