Check the calendar widget and the tooltips on the credit card fields.
The form uses Ajax-based validations to redisplay server-side errors without refreshing the entire page.
The booking bean backing the form is a flow-scoped object (see <strong>booking-flow.xml</strong>).

Di sini saya mencoba mendapatkan beberapa nilai dari hello.xhtml dan mencoba mengevaluasinya di main-flow.xml.
Jika nilai yang saya coba baru maka harus menavigasi ke halaman1 atau harus membawanya ke halaman2.xhtml. Sekarang saya kasus saya bahkan saya memasukkan yang baru di kotak teks masukan saya hanya perlu ke halaman2. Ada yang bisa bantu saya.
