Summing Joda Money?

[Marty Pitt]

Is it possible to perform math / aggregate operations on Joda's Money type?

I'm using UserType to provide support, which essentially persists the money as a BigDecimal.

I've tried the following, to no avail:

BigDecimal result = query().from($ledgerPost).singleResult($post.value.castToNum(BigDecimal.class).sum());

(where $post.value is of type Money).

However, this fails with a NullPointerException (see below).  Is there a way to support these operations?  If not in-built, then is there a way to extend QueryDSL to provide support for these user types?  (I understand why you might not want to introduce the JodaMoney dependency)

Cheers,

Marty
