Issue while using adaptto of a custom Model that implements a Core interface in a different Sling Model

Hi

Some context I have a SlingModel that implements the Accordion core interface that is mapped to a AEM component lets call it component X
I have another AEM component lets call it Component Y with a corresponding Sling Model that needs some info from the other component (component X).

When I want to adapt in the Sling model of component Y a Resource to the Sling model of Component X with AdaptTo method.
All my "own" fields are mapped correctly  but the accordion variable is null after the adaptTo().
If I open Component X the mapping is correct and I see the correct data.

@Getter
@Model(adaptables = {SlingHttpServletRequest.class, Resource.class},
        resourceType = {ExperienceZoneScreenModel.RESOURCE_TYPE},
        defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class ComponentXModel implements Accordion {

    @Self
    @Via(type = ResourceSuperType.class)
    private Accordion accordion

 @ValueMapValue
private String title;


public List<PanelContainerItem> getConfiguredItems() {
 return accordion.getChildren();
}
...


}

@Model(adaptables = {Resource.class, SlingHttpServletRequest.class})
public class ComponentYModel {

 public String getItems() {
   ....
 ComponentXModel cmp = child.adaptTo(ComponentXModel.class);
 cmp.getTitle(); // Provide the right title
cmp.getConfiguredItems(); // accordion is null
