lombok delegation pattern not returning all methods in model.json(Json Exporter) for Tabs component - aem

Question

I am using delegation pattern using lombok - hoping all getter method of parent super type will be exported in model.json
This is the sling model I wrote for Tabs component
package com.test.internal.models;
import com.adobe.cq.export.json.ComponentExporter;
import com.adobe.cq.export.json.ContainerExporter;
import com.adobe.cq.export.json.ExporterConstants;
import com.adobe.cq.wcm.core.components.internal.models.v1.TabsImpl;
import com.adobe.cq.wcm.core.components.models.Component;
import com.adobe.cq.wcm.core.components.models.Container;
import com.adobe.cq.wcm.core.components.models.ListItem;
import com.adobe.cq.wcm.core.components.models.Tabs;
import com.adobe.cq.wcm.core.components.models.datalayer.ComponentData;
import lombok.experimental.Delegate;
import org.apache.commons.lang3.StringUtils;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.models.annotations.*;
import org.apache.sling.models.annotations.injectorspecific.Self;
import org.apache.sling.models.annotations.injectorspecific.ValueMapValue;
import org.apache.sling.models.annotations.via.ResourceSuperType;
import javax.inject.Inject;
import java.util.List;
#Model(
adaptables = {Resource.class, SlingHttpServletRequest.class},
adapters = {Tabs.class,ComponentExporter.class, ContainerExporter.class, Container.class},
resourceType = Accordion.RESOURCE_TYPE
)
#Exporter(
name = ExporterConstants.SLING_MODEL_EXPORTER_NAME,
extensions = ExporterConstants.SLING_MODEL_EXTENSION
)
public class Accordion implements Tabs {
static final String RESOURCE_TYPE = "test/components/accordion";
#Self #Via(type = ResourceSuperType.class)
#Delegate(types = Tabs.class,excludes = DelegationExclusion.class)
private com.adobe.cq.wcm.core.components.models.Tabs delegate;
#Override
public String getActiveItem() {
return "test";
}
private interface DelegationExclusion { // Here we define the methods we want to override
String getActiveItem();
}
}
I am trying to override the getActiveItem method for Tabs component. But it's not populating the items properly - they are empty in the json - just returning the overridden method in the json -
"accordion": {
"items": [],
"activeItem": "test",
":itemsOrder": [],
":items": {}
}
when I remove this Sling model from the bundle - the OOTB sling model comes into picture and returns everything -
"accordion": {
"id": "accordion-5248ba2449",
"activeItem": "item_1",
":itemsOrder": [
"item_1",
"item_2",
"ctabutton"
],
":items": {
"item_1": {
"gridClassNames": "aem-Grid aem-Grid--12 aem-Grid--default--12",
"columnClassNames": {
"backbutton": "aem-GridColumn aem-GridColumn--default--12"
},
"columnCount": 12,
"allowedComponents": {
"components": [],
"applicable": false
},
":itemsOrder": [
"backbutton"
],
":items": {
"backbutton": {
":type": "test/components/backbutton",
"btnLabel": "View More"
}
},
":type": "test/components/container",
"cq:panelTitle": "FAQ 1"
},
"item_2": {
"gridClassNames": "aem-Grid aem-Grid--12 aem-Grid--default--12",
"columnClassNames": {},
"columnCount": 12,
"allowedComponents": {
"components": [],
"applicable": false
},
":itemsOrder": [],
":items": {},
":type": "test/components/container",
"cq:panelTitle": "FAQ 2"
},
"ctabutton": {
":type": "test/components/ctabutton",
"btnAlignment": "left",
"lightboxId": "sadasdasdasdasdas",
"btnType": "cta-primary",
"btnLabel": "View More",
"openLightbox": "true",
"cq:panelTitle": null
}
},
":type": "test/components/accordion"
}
can someone please let me know what is missing in sling model that it's not returning the items properly

Here is working example from project, should help you.
#Model(
adaptables = SlingHttpServletRequest.class,
adapters = { Tabs.class, ComponentExporter.class, ContainerExporter.class },
resourceType = absModel.TABS_RESOURCE_TYPE,
defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL
)
#Exporter(
name = ExporterConstants.SLING_MODEL_EXPORTER_NAME,
extensions = ExporterConstants.SLING_MODEL_EXTENSION
)
#JsonSerialize(as = TabsModel.class)
public class TabsModel implements Tabs {
protected static final String TABS_RESOURCE_TYPE = "myproject/components/tabs";
#Self
private SlingHttpServletRequest request;
#Self
#Via(type = ResourceSuperType.class)
#Delegate(excludes = Excludes.class)
private Tabs tabs;
#Override
public String getExportedType() {
return this.request.getResource().getResourceType();
}
private interface Excludes {
String getExportedType();
}
}
