How to init WPS in 'admin_init' to use get_post_types?

Thanks

Solution: move $this->wpsf = new WordPressSettingsFramework( $this->plugin_path . 'settings/settings-general.php', 'prefix_settings_general' ); to add_settings_page function. But Im not sure add_filter($this->wpsf->get_option_group() . '_settings_validate', array(&$this, 'validate_settings')); work.
