Hello, I'm updated teneo version to 0.8.0.v200707121518,
I want to use new version in order to correct
https://bugs.eclipse.org/bugs/show_bug.cgi?id=185717 bug.
Casused exception:
org.hibernate.MappingException: Foreign key
(FKF8C83C375882C2E:dtsadd_paymentdescription [dtsadditionalpaymentst_id]))
must have same number of columns as the referenced primary key
(dtsadditionalpaymentstype
[dtsadditionalpaymentst_id,dtsadditionalpayments_idx])
at org.hibernate.mapping.ForeignKey.alignColumns(ForeignKey.jav a:90)
at org.hibernate.mapping.ForeignKey.alignColumns(ForeignKey.jav a:73)
....
Should I use some persistence options?
I tried to use PersistenceOptions.JOIN_COLUMN_NAMING_STRATEGY with "unique"
options, but it was useless.
code:
....
final Properties persisence=new Properties();
persisence.put(PersistenceOptions.JOIN_TABLE_NAMING_STRATEGY , "ejb3");
persisence.put(PersistenceOptions.MAXIMUM_SQL_NAME_LENGTH, "25");
persisence.put(PersistenceOptions.INHERITANCE_MAPPING, "JOINED");
// persisence.put(PersistenceOptions.PERSISTENCE_XML , "persistence.xml");
// used earlier
persisence.put(PersistenceOptions.JOIN_COLUMN_NAMING_STRATEG Y, "unique");
hbds.setPersistenceProperties(persisence);
I used to use persistence mapping file, but now it doesn't help.What wrong?

Can you post the part of the generated hbm which covers this assocation?

Thanks, yes I found the ecores.
>> Scale
The scale is read from the annotation meta data (fractionDigits), this should be okay.
>> Different Date mapping
It was the other way around the latest Teneo release now correctly identifies the date types,
therefore it does not use typedef's in the top of the hbm anymore. This also means however that the
mapping to the database has changed (it uses a date column instead of a string column).
>> The Exception
I tested this and the exception was caused by the following bug (or feature):
The latest release of Teneo now also computes the table name for list of primitive types. This table
name computation also does truncation if the name is too long (according to the options).
The problem with truncation logic is that it can result in non-unique naming (as the unique part is
truncated away).
This resulted in a eclass and a list of primitive string to be placed in the same table. You can
search the new hbm for the text table="`dtsadditionalpaymentstype`" and then you will see it appear
twice.
The primitive list causes this table to have two columns in the pk (the id and the idx).
I solved this by changing the truncation logic (there was a bug in it actually which caused it to
truncate away the wrong part). This will be in the next build.
Note that the new join table naming logic for primitive lists means that the generated hbm is not
backward compatible with the old db schema (only if the names are too long). So you need to use
jointable annotations to force Teneo to use the old tablenames (or transfer to a new db-schema).
Btw, the latest Teneo release offers an easier method to extend or override the sql naming strategy
(see extensions on the elver.org website).
