Transfer-ORM: The property 'siteID' could not be found in the object 'siteUsers.siteUsers'

Question

I'm getting the following Coldfusion error when using Transfer-ORM to map to my Microsoft SQL database. I believe it's caused by a misconfigured transfer.xml file that maps out my linking table. I'm not sure I entirely understand the nuances of the composite id. Do you see the error?

Error:

The property that was searched for could not be found The property 'siteID' could not be found in the object 'siteUsers.siteUsers'

Answer 1

Possible reason is that you define both o2m and m2o for same relationship. As I remember, this is not allowed.

Answer 2

To properly configure Transfer-ORM, there are three things to validate about the configuration file:

1. Is it properly formed XML?

2. Does it conform to the transfer.xsd schema file?

3. Do the relationships in your transfer.xml match the relationships in your database?

I passed validation on #1 and #2, but was using the wrong relationship tags in #3.
