You’re awesome. Keep doing this great work!
Thanks!
I agree. Great job. I am hoping that the date input will be one of the next components on the list. I know you guys are building out the most important base pieces first. That component is almost a necessity for our forms.
There is already a datepicker in jQuery UI.
Keep the great job. You already rule JSF2, now you will rule jQuery UI Widgets !!!
