BuddyPress Theme compatibility not working properly when default_subnav_slug is not specified for a component

[sbrajesh]

BuddyPress allows registering a component(nav) without specifying the default_subnav_slug. In the current implementation if you do not specify default_subnav_slug, the theme compatibility does not work properly.

It treats the component page as members directory instead of user section. The reason is the condition check in class-bp-members-theme-compat.php

Intstead of checking for directory first, It should test for the user first. I other words, changing the order of conditions in is_members() fixes the issue.
The code

	public function is_members() {

		// Bail if not looking at the members component or a user's page.
		if ( ! bp_is_members_component() && ! bp_is_user() ) {
			return;
		}

		// Members Directory.
		if ( ! bp_current_action() && ! bp_current_item() ) {
			bp_update_is_directory( true, 'members' );

			/**
			 * Fires if looking at Members directory when needing theme compat.
			 *
			 * @since 1.5.0
			 */
			do_action( 'bp_members_screen_index' );

			add_filter( 'bp_get_buddypress_template',                array( $this, 'directory_template_hierarchy' ) );
			add_action( 'bp_template_include_reset_dummy_post_data', array( $this, 'directory_dummy_post' ) );
			add_filter( 'bp_replace_the_content',                    array( $this, 'directory_content'    ) );

		// User page.
		} elseif ( bp_is_user() ) {

			// If we're on a single activity permalink page, we shouldn't use the members
			// template, so stop here!
			if ( bp_is_active( 'activity' ) && bp_is_single_activity() ) {
				return;
			}

			/**
			 * Fires if looking at Members user page when needing theme compat.
			 *
			 * @since 1.5.0
			 */
			do_action( 'bp_members_screen_display_profile' );

			add_filter( 'bp_get_buddypress_template',                array( $this, 'single_template_hierarchy' ) );
			add_action( 'bp_template_include_reset_dummy_post_data', array( $this, 'single_dummy_post'    ) );
			add_filter( 'bp_replace_the_content',                    array( $this, 'single_dummy_content' ) );

		}
	}

needs to be changed to this

	public function is_members() {

		// Bail if not looking at the members component or a user's page.
		if ( ! bp_is_members_component() && ! bp_is_user() ) {
			return;
		}

		// User page.
		if ( bp_is_user() ) {

			// If we're on a single activity permalink page, we shouldn't use the members
			// template, so stop here!
			if ( bp_is_active( 'activity' ) && bp_is_single_activity() ) {
				return;
			}

			/**
			 * Fires if looking at Members user page when needing theme compat.
			 *
			 * @since 1.5.0
			 */
			do_action( 'bp_members_screen_display_profile' );

			add_filter( 'bp_get_buddypress_template',                array( $this, 'single_template_hierarchy' ) );
			add_action( 'bp_template_include_reset_dummy_post_data', array( $this, 'single_dummy_post'    ) );
			add_filter( 'bp_replace_the_content',                    array( $this, 'single_dummy_content' ) );
		// Members Directory.
		} elseif ( ! bp_current_action() && ! bp_current_item() ) {
			bp_update_is_directory( true, 'members' );

			/**
			 * Fires if looking at Members directory when needing theme compat.
			 *
			 * @since 1.5.0
			 */
			do_action( 'bp_members_screen_index' );

			add_filter( 'bp_get_buddypress_template',                array( $this, 'directory_template_hierarchy' ) );
			add_action( 'bp_template_include_reset_dummy_post_data', array( $this, 'directory_dummy_post' ) );
			add_filter( 'bp_replace_the_content',                    array( $this, 'directory_content'    ) );


		}
	}

It will be nice to have a fix in 3.0
Thank you.
