Hello, we have a Angular4 web application running with keycloak.js that works great. We are now trying to put this application into a cordova container running on iOS, but in the login function of the keycloak cordova adapter var loginUrl = kc.createLoginUrl(options); var ref = window.open(loginUrl, '_blank', o); ref is always null, so adding the event listener fails ?!? We are bootstrapping (main.ts) our angular application like this: function bootstrapKeyCloak() { KeycloakService.init({ 'url': environment.keycloakConfig.url, 'realm': environment.keycloakConfig.realm, 'clientId': environment.keycloakConfig.clientId, }, { onLoad: 'login-required', flow: 'standard' }).then(() => { platformBrowserDynamic().bootstrapModule(AppModule); }).catch((e: any) => { alert(e); }); } if (typeof window['cordova'] !== 'undefined') { if(document) { document.addEventListener('deviceready', () => { bootstrapKeyCloak(); }, false); } } else { bootstrapKeyCloak(); } Any ideas why window.open fails and how to fix this? -- Kind Regards, Jens Schliesser
