Process Variables stored as Date have problems...here's reso

Process Variables stored as Date are returned as Timestamp(at least in Hypersonic SQL). DateToLongConverter does not support that.

Since Date are stored as Timestamps....the DateInstance and DateToLongConverter class need to be able to support them. Right now they only support Date.class.

Change DateInstance.java and DateToLongConverter.java's support function to be:

protected boolean supports(Class clazz) {
return Date.class.isAssignableFrom(clazz);
}

This will allow conversion from any implementation of date...rather than just date itself.

OK, I have the same problem but has not fully understand this message.

After some investigation I understand the problem:

Some Hibernate Dialects (HSQL, Oracle9, ...) return a java.sql.Timestamp, instead of a java.util.Date. That's OK, because Timestamp is a subclass of Date.

But because of the DateInstance implementation

protected boolean supports(Class clazz) { return (Date.class==clazz); }

The Timestamp is not recognized as Date from jbpm. So the implementation must be changed to

protected boolean supports(Class clazz) { // fixed Bug with jbpm and Oracle // see http://www.jboss.com/index.html?module=bb&op=viewtopic&t=70042 return (Date.class.isAssignableFrom(clazz)); }

Then it works fine.

But I have wondered how this Bug made it into 3.0.2....

I hope, it will be fixed with 3.1?

I'm pretty sure I once changed this, but It could have been on the trunk and not the 3.0 branche. In that case this bug has been there from the start of 3.0. If it was not even on the 3.1 branche than I'm totally flabbergasted
