Hi all,
I have three tables, with the following structure:

The three objects I'm dealing with are here:
http://dl.dropbox.com/u/2586403/ORMIssues/Objects.zip
I need to be able to get a PartObject, and then pull all of its Attributes, sorted by the AttributeName in the Types table. Here are the problems I'm running into:
I can't sort the Attributes property in PartObject by its Attribute.AttributeName property
I can't add the Attribute.AttributeName property to the ObjectAttribute entity because I get an error regarding column names. Hibernate is putting the ID on the wrong side of the join
Here's the hibernate log file showing the bad query
10/14 16:36:39 [jrpp-12] HIBERNATE DEBUG - select objectattr0_.ID as ID1116_, objectattr0_.AttributeValue as Attribut2_1116_, objectattr0_.AttributeID as Attribut3_1116_, objectattr0_1_.AttributeName as Attribut2_1117_ from ObjectAttributes objectattr0_ inner join Attributes objectattr0_1_ on objectattr0_.ID=objectattr0_1_.AttributeID
10/14 16:36:39 [jrpp-12] HIBERNATE ERROR - [Macromedia] [SQLServer JDBC Driver][SQLServer]Invalid column name 'AttributeID'.
10/14 16:36:39 [jrpp-12] HIBERNATE ERROR - [Macromedia] [SQLServer JDBC Driver][SQLServer]Statement(s) could not be prepared.
Here's the offending section of the query:
from ObjectAttributes objectattr0_
inner join Attributes objectattr0_1_ on objectattr0_.ID=objectattr0_1_.AttributeID
It should be:
from ObjectAttributes objectattr0_
inner join Attributes objectattr0_1_ on objectattr0_.AttributeID=objectattr0_1_.ID
The AttributeName property on the ObjectAttribute.cfc is the one causing the problem:
component output="false" persistent="true" table="ObjectAttributes"
{
property name="ID" column="ID" generator="native" type="numeric" ormtype="int" fieldtype="id" unsavedvalue="0" ;
property name="AttributeValue" type="string" ;
property name="Attribute" fieldtype="many-to-one" cfc="Attribute" fkcolumn="AttributeID" fetch="join";
property name="AttributeName" table="Attributes" joincolumn="AttributeID" ;
}
I've also tried using a formula to get the AttributeName on the ObjectAttribute entity, like so:
component output="false" persistent="true" table="ObjectAttributes"
{
property name="ID" column="ID" generator="native" type="numeric" ormtype="int" fieldtype="id" unsavedvalue="0" ;
property name="AttributeValue" type="string" ;
property name="Attribute" fieldtype="many-to-one" cfc="Attribute" fkcolumn="AttributeID" fetch="join";
property name="AttributeName" type="string" formula="(SELECT A.AttributeName FROM Attributes A WHERE A.ID = AttributeID)";
}
This works, but I can't sort by that computed column. If I then adjust PartObject.cfc like so:
property name="Attributes" cfc="ObjectAttribute" type="array" fkcolumn="ObjectID" fieldtype="one-to-many" orderby="AttributeName";
I get the following errors in the hibernatesql log:
10/17 16:51:55 [jrpp-0] HIBERNATE DEBUG - select attributes0_.ObjectID as ObjectID2_, attributes0_.ID as ID2_, attributes0_.ID as ID244_1_, attributes0_.AttributeValue as Attribut2_244_1_, attributes0_.AttributeID as Attribut3_244_1_, ((SELECT A.AttributeName FROM Attributes A WHERE A.ID = attributes0_.AttributeID)) as formula25_1_, attribute1_.ID as ID246_0_, attribute1_.AttributeName as Attribut2_246_0_ from ObjectAttributes attributes0_ left outer join Attributes attribute1_ on attributes0_.AttributeID=attribute1_.ID where attributes0_.ObjectID=? order by attributes0_.AttributeName
10/17 16:51:55 [jrpp-0] HIBERNATE ERROR - [Macromedia][SQLServer JDBC Driver][SQLServer]Invalid column name 'AttributeName'.
10/17 16:51:55 [jrpp-0] HIBERNATE ERROR - [Macromedia][SQLServer JDBC Driver][SQLServer]Statement(s) could not be prepared.
Here's a dump without that property to show that the rest of the relationships are working properly:

I have no idea how to fix this issue. Any help you can provide would be greatly appreciated.
Thanks,
