Hi all,
Our new application is not configurable, despite implementing the MVC portlet like described in the 7.1 documentation, https://portal.liferay.dev/docs/7-1/tutorials/-/knowledge_base/t/making-applications-configurable.
We made a configuration interface, a bean declaration and configuration category like mentioned in the docu.
But we can not see the an entry in the system settings section "other".
We debugged the portal an saw that the bundle didn't have a categoryPid / pid in the MetaTypeInformation, see

ConfigurationModelRetrieverImpl.collectConfigurationModels()

How this can happen?
Is there a new documentation for 7.2 or do we have to implement someting additionally? We found nothing ...
Does anybody know what's the problem here?
Thank you very much!
Tested with CE 7.2.1 GA2 and DXP 7.2.10 GA1.
Handling of the configuration interface in general works, because the default value is fetched correct in the configuration.jsp of the portlet.

Implementation:
configuration interface:

@ExtendedObjectClassDefinition(
	category = "facility-references", factoryInstanceLabelAttribute = "ddmStructureName",
	scope = ExtendedObjectClassDefinition.Scope.SYSTEM
)
@Meta.OCD(
	factory = true,
	id = "com.company.portal.facility.references.web.configuration.FacilityReferencesConfiguration",
	localization = "content/Language",
	name = "facility-references-web-configuration-name"
)
public interface FacilityReferencesConfiguration {

	@Meta.AD(deflt = "Facility-Reference", name = "ddm-structure-name", required = false)
	String ddmStructureName();

}

bean declaration:

@Component(service = ConfigurationBeanDeclaration.class)
public class FacilityReferencesConfigurationBeanDeclaration implements ConfigurationBeanDeclaration {
     
	@Override
	public Class<!--?--> getConfigurationBeanClass() {
		return FacilityReferencesConfiguration.class;
	}
	
}

configuration category:

@Component(service = ConfigurationCategory.class)
public class FacilityReferencesConfigurationCategory
	implements ConfigurationCategory {

	@Override
	public String getCategoryIcon() {
		return _CATEGORY_ICON;
	}

	@Override
	public String getCategoryKey() {
		return _CATEGORY_KEY;
	}

	@Override
	public String getCategorySection() {
		return _CATEGORY_SECTION;
	}

	private static final String _CATEGORY_ICON = "web-content";

	private static final String _CATEGORY_KEY = "facility-references";

	private static final String _CATEGORY_SECTION = "other";

}

configuration form renderer:

@Component(immediate = true, service = ConfigurationFormRenderer.class)
public class FacilityReferencesConfigurationFormRenderer
    implements ConfigurationFormRenderer {

    @Override
    public String getPid() {
        return "com.company.portal.facility.references.web.configuration.FacilityReferencesConfiguration";
    }

    @Override
    public void render(HttpServletRequest request, HttpServletResponse response)
            throws IOException {
            
        String formHtml = "<input name="\&quot;ddmStructureName\&quot;">";

        PrintWriter writer = response.getWriter();

        writer.print(formHtml);

    }

    @Override
    public Map<string, object> getRequestParameters(
            HttpServletRequest request) {

        Map<string, object> params = new HashMap&lt;&gt;();

        String ddmStructureName = ParamUtil.getString(request, "ddmStructureName");

        params.put("ddmStructureName", ddmStructureName);

        return params;
    }
}
</string,></string,>

portlet:

@Component(
	configurationPid = "com.company.portal.facility.references.web.configuration.FacilityReferencesConfiguration",
	immediate = true,
	property = {
		"com.liferay.portlet.display-category=category.applications",
		"com.liferay.portlet.header-portlet-css=/css/main.css",
		"com.liferay.portlet.instanceable=true",
		"javax.portlet.display-name=FacilityReferences",
		"javax.portlet.init-param.template-path=/",
		"javax.portlet.init-param.view-template=/view.jsp",
		"javax.portlet.name=" + FacilityReferencesPortletKeys.FACILITYREFERENCES,
		"javax.portlet.resource-bundle=content.Language",
		"javax.portlet.security-role-ref=power-user,user"
	},
	service = Portlet.class
)
public class FacilityReferencesPortlet extends MVCPortlet {

	@Activate
	@Modified
	protected void activate(Map<object, object> properties) throws Exception {
		configuration = ConfigurableUtil.createConfigurable(FacilityReferencesConfiguration.class, properties);
	}
</object,>
