I have created a multifield component with a sling model. I cannot render the content using sling models.

Error: org.apache.sling.api.SlingException: Cannot get DefaultSlingScript:

=============== SocialShareItemsModel =====================

import org.apache.sling.api.resource.Resource;

import org.apache.sling.models.annotations.DefaultInjectionStrategy;

import org.apache.sling.models.annotations.Model;

import org.apache.sling.models.annotations.injectorspecific.ValueMapValue;

 

@Model(adaptables = Resource.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)

public class SocialShareItemsModel {

 

@ValueMapValue

private String socialicon;

 

@ValueMapValue

private String socialMediaUrl;

 

public String getSocialicon() {

return socialicon;

}

 

public String getSocialMediaUrl() {

return socialMediaUrl;

}

}

import org.apache.sling.models.annotations.DefaultInjectionStrategy;

@Model(adaptables = SlingHttpServletRequest.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)

public class SocialShareModel {

 

@ChildResource

private List<SocialShareItemsModel> mediaitems = new ArrayList<SocialShareItemsModel>();

 

public List<SocialShareItemsModel> getMediaitems() {

return mediaitems;

}

}

      Hi @anilkumar9!

      Would you mind sharing the error/exception including stack traces from the error.log file for this issues? This would help with further analysis and support.

        Hi @anilkumar9 

         

        It looks like there might be a typo in your Sightly code where you're trying to access the socialicon property. The property in your Sling model is named socialicon, but in your Sightly code, you're trying to use item.socialIcon.

         

        <sly data-sly-use.model="com.sample.core.models.SocialShareModel"> <sly data-sly-list="${model.mediaitems}"> <a class="icon-link" href="${item.socialMediaUrl}"> <img src="${item.socialicon}"> <!-- Corrected property name --> </a> </sly> </sly>

         

        Here, I corrected the property name from socialIcon to socialicon to match your Sling model. Make sure to use the exact property names as defined in your model.

        If the issue persists, you may also want to check if the mediaitems list is not null in your Sightly code to avoid potential null pointer exceptions:

        <sly data-sly-use.model="com.sample.core.models.SocialShareModel"> <sly data-sly-list="${model.mediaitems}"> <sly data-sly-test="${item != null}"> <a class="icon-link" href="${item.socialMediaUrl}"> <img src="${item.socialicon}"> </a> </sly> </sly> </sly>
         

        This checks if item is not null before trying to access its properties.

         

         

        Also check your error.log file and share the complete error report so that we can debug it in better way.
