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

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.
