The JSF RI 1.1 has poor error reporting. This makes it difficult to
figure out the real problem sometimes. At minimum, you might want to
at least try running it against MyFaces Core. That doesn't mean you
can't switch back to JSF RI once you've determined the problem.
I've had no issues with using inputCalendar pointing to a null backing
bean date.

Hi,
I am having a mind-numbingly frustrating issue with inputCalendar. Hooked
up to a bean with a null date, I am getting a NullPointerException (I am
assuming, of course, that the tag can/should handle it - am I wrong?)
My tag ...
<t:inputCalendar renderPopupButtonAsImage="true" renderAsPopup="true"
value="#{bean.my_date}" />
The exception ...

If the date is non-null everything is fine. If I save a blank date or just
read a blank date from the db, I get the error. As you can see, I am using
the Sun jsf implementation with Tomahawk. Should I abandon Sun and go with
MyFaces implementation?
