Subject Re: inputCalendar not saving value into backing bean
Date Wed, 07 May 2008 12:57:58 GMT

Have you got the correct scope on your backing bean data?
If the bean is reset to the initial value, this is often because it is a new
instance of the bean.
If the bean has only request scope, the bean when you look at the value may
not be the same instance of the bean where you set the value.
