Hi,

We would like that folders and docs in Document Library inherit the same permissions from their parents. It actually happens on wiki, its folders inherit permissions of their ancestors.  In wiki portlet we saw that this mechanism is implemented in the way explained below.

AtPortletConfigurationPortlet.java  it checks if  permissions.propagation.enabled is true at portal-ext.properties. If that portlet has  PermissionPropagator class implemented, then it is triggered whenever permissions are changed:

 ....

    if (PropsValues.PERMISSIONS_PROPAGATION_ENABLED) {
            Portlet portlet = _portletLocalService.getPortletById(
                themeDisplay.getCompanyId(), portletResource);

            PermissionPropagator permissionPropagator =
                portlet.getPermissionPropagatorInstance();

            if (permissionPropagator != null) {
                permissionPropagator.propagateRolePermissions(
                    actionRequest, modelResource, resourcePrimKey, roleIds);
            }
        }

....

Wiki portlet  has PermissionPropagator implemented this way on WikiPermissionPropagatorImpl:

/**
 * @author Hugo Huijser
 * @author Angelo Jefferson
 */
@Component(
    immediate = true,
    property = {
        "javax.portlet.name=" + WikiPortletKeys.WIKI,
        "javax.portlet.name=" + WikiPortletKeys.WIKI_ADMIN,
        "javax.portlet.name=" + WikiPortletKeys.WIKI_DISPLAY
    },
    service = PermissionPropagator.class
)
public class WikiPermissionPropagatorImpl extends BasePermissionPropagator {

    @Override
    public void propagateRolePermissions(
            ActionRequest actionRequest, String className, String primKey,
            long[] roleIds)
        throws PortalException {

        if (!className.equals(WikiNode.class.getName())) {
            return;
        }

        long nodeId = GetterUtil.getLong(primKey);

        List<WikiPage> wikiPages = _wikiPageLocalService.getPages(
            nodeId, QueryUtil.ALL_POS, QueryUtil.ALL_POS);

        for (WikiPage wikiPage : wikiPages) {
            for (long roleId : roleIds) {
                propagateRolePermissions(
                    actionRequest, roleId, WikiNode.class.getName(), nodeId,
                    WikiPage.class.getName(), wikiPage.getResourcePrimKey());
            }
        }
    }

Trying to do it in a similar way at Document Library, it does not work and it is never triggered

@Component(
        immediate = true,
        property = {

                "javax.portlet.name=" + "com_liferay_document_library_web_portlet_DLPortlet",
                "javax.portlet.name=" + "com_liferay_document_library_web_portlet_DLAdminPortlet",
                "javax.portlet.name=" + "com_liferay_document_library_web_portlet_IGDisplayPortlet"
        },
        service = PermissionPropagator.class
)
public class MyCustomDLPermissionPropagatorImpl extends BasePermissionPropagator {
 

        @Override
        public void propagateRolePermissions(
                        ActionRequest actionRequest, String className, String primKey,
                        long[] roleIds)
                throws PortalException {

                System.out.println("---MyCustomDLPermissionPropagatorImpl has been called!! --);
 

        }
 

It seems that we are missing something or this could not even be the way of doing so.

Any tip or help would be geatly appreciatted

TIA
