HiddenField doesn't work with Timestamp, Time or java.sql.Date

[Bob Schellink]

When setting a HiddenField's valueClass to Timestamp, an exception is 
thrown in HiddenField#bindRequestValue:

java.lang.IllegalArgumentException: The value.getClass(): 
'java.util.Date' must be the same as the HiddenField valueClass: 
'java.sql.Timestamp'
  at 
org.apache.click.control.HiddenField.setValueObject(HiddenField.java:239)
  at 
org.apache.click.control.HiddenField.bindRequestValue(HiddenField.java:295)
  at 
org.apache.click.control.HiddenFieldTest.testTimestampCopy(HiddenFieldTest.java:66)


An easy fix is to add extra checks for #bindRequestValue:

  else if (valueClass == Timestamp.class) {
    long time = Long.parseLong(aValue);
    setValueObject(new Timestamp(time));

  } else if (valueClass == java.sql.Date.class) {
    long time = Long.parseLong(aValue);
    setValueObject(new java.sql.Date(time));

  } else if (valueClass == Time.class) {
    long time = Long.parseLong(aValue);
    setValueObject(new Time(time));

  } else if (Date.class.isAssignableFrom(valueClass)) {
    // catchall check
  }
