Question

[[EMAIL PROTECTED]]

I have this bit of code:

            GenericValue payment = delegator.findByPrimaryKey("Payment",
UtilMisc.toMap("paymentId", paymentId));
...
            GenericValue paymentMethod =
payment.getRelatedOne("PaymentMethod");

The javadoc for getRelatedOne sez:

Parameters:
    relationName - String containing the relation name which is the
combination of relation.title and relation.rel-entity-name as specified in
the entity XML definition file.

I did not quite understand this statement as it does not seem to make sense
in this context.  Is this parameter a concatination of "Payment" and
"Method" where Payment is the relation.title and Method is the
relation.rel-entity-name?

I kinda dont think so.  I looked in the entitydef file containg Payment and
found this:

      <relation type="one" fk-name="PAYMENT_PMETH"
rel-entity-name="PaymentMethod">
        <key-map field-name="paymentMethodId"/>
      </relation>

So, I am assuming that this particular getRelatedOne call is going to open
the PaymentMethod entity and find the related "paymentMethodId" record.

Is this correct?

Also, if I see a yyy.getRelatedOne(xxx), can I assume that xxx is the entity
name to look in and xxxId is the key name in xxx always?

Thanks
