My approach is I get component resource by resourceType after I get InheritanceValueMap of the component. I have a problem when I get InheritanceValueMap, I don't get child node properties.
I think if multifield save by JSON array, I can get the inheritance of multifield properties.
@Model(adaptables = { SlingHttpServletRequest.class, Resource.class }, adapters = { FooterModel.class,
ComponentExporter.class }, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL, resourceType = FooterModelImpl.RESOURCE_TYPE)
