Using java.util.Calendar with the calendar form element

[jsp]

Alot of our date related fields use java.util.Calendar instead of java.util.Date.

<p:calendar id="blah" value="#{myBean.myObject.myDate.time}" />

I get errors at runtime if field myDate (which is a java.util.Calendar) is null.

Is there a way around this?

Just set a default value in your bean. [something like Calendar.getInstance();]

[jsp]

The date/calendar fields are stored in the database. Null is a valid value for many of the date/calendar fields so providing a default value isn't really an option.

I had to add a custom converter allow the primefaces Calendar component to convert to and from a java.util.Calendar.

While not ideal, I used the code that primefaces uses to convert to and from java.util.Date after getting or setting the date from the java.util.Calendar object.

It would be nicer if primefaces either supported this natively or if there at least was a primefaces DateTimeConverter that I could extend.

Oh yeah, I also changed my page:

From this:
<p:calendar id="blah" value="#{myBean.myObject.myDate.time}" />

To this:
<p:calendar id="blah" value="#{myBean.myObject.myDate}" converter="primefacesCalendarConverter"/>
