I solved the problem using a Converter. I used this Ilya Shaikovsky's example in this thread as a starting point:  http://community.jboss.org/message/57921#57921 http://community.jboss.org/message/57921

in faces-config.xml:

{code}
 <converter>
  <converter-id>calendarTimestampConverter</converter-id>
  <converter-class>my.client.CalendarTimestampConverter</converter-class>
 </converter>
{code}

CalendarTimestampConverter.java:

{code}
package my.client;


import java.util.Date;


import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.ConverterException;
import javax.faces.convert.DateTimeConverter;


import org.apache.log4j.Logger;


public class CalendarTimestampConverter extends DateTimeConverter {

          private Logger logger = Logger.getLogger(getClass()); 

          @Override
          public Object getAsObject(FacesContext arg0, UIComponent component,
                              String dateString) {
                    logger.debug("getAsObject(): " + dateString);
                    Object result;
                    try {
                              result = super.getAsObject(arg0, component, dateString);
                              if (result instanceof Date) {
                                        //make it a Timestamp, because that is what jBPM will make of it anyway
                                        result = new java.sql.Timestamp(((Date) result).getTime());
                              }
                    } catch (ConverterException ex) {
                              return null;
                    }
                    return result;
          }


          @Override
          public String getAsString(FacesContext arg0, UIComponent component,
                              Object dateObject) {
                    logger.debug("getAsString(): " + (dateObject == null ? null : (dateObject.getClass().getSimpleName() + " " + dateObject.toString())));
                    String result = null;
                    try {
                              result = super.getAsString(arg0, component, dateObject);
                    } catch (ConverterException ex) {
                              return null;
                    }
                    return result;
          }
}
{code}

Then I simply add converter="calendarTimestampConverter" to my rich:calendar, and presto! No more jBPM problems.

Still, this is a hack and should be fixed in jBPM, IMO.
