I generated with Texo project to connect to database with EntityManager - hibernate.

The problem is that Texo generated my list as FeatureList:

private List<ListTypeGroupFeatureGroup> group = new ArrayList<ListTypeGroupFeatureGroup>();

There are no assigned annotations and then:

EntityManagerProvider.getInstance().setPersistenceUnitName("MyManager");
EntityManagerProvider.getInstance().initialize();
cause an error:

Caused by: org.hibernate.MappingException: Could not determine type for: java.util.List, at table: ListType, for columns: [org.hibernate.mapping.Column(group)]

Where is the problem? In Texo or in my configuration?

I attach my model files and persistence to test.

I will add here some more details:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns="http: //creconfigdir.model" targetNamespace="http: //creconfigdir.model" xmlns:xs="http: //www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:complexType name="listType">
<xs:sequence minOccurs="1" maxOccurs="unbounded">
<xs:element name="file">
<xs:complexType>
<xs:attribute name="valid_from" type="xs:dateTime" use="required"/>
<xs:attribute name="name" type="xs:string" use="required"/>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
<xs:element name="list" type="listType"/>
</xs:schema>

The list type is translated to code:
@Entity(name = "ListType")
public class ListType extends Identifiable {
//here I think there are missing some annotations
private List<ListTypeGroupFeatureGroup> group = new ArrayList<ListTypeGroupFeatureGroup>();
...

And later:
public class ListTypeGroupFeatureGroup {
...
@ManyToOne(cascade = { CascadeType.ALL }, optional = false, targetEntity = FileType.class)
@JoinColumns({ @JoinColumn() })
private FileType file;

I think there is something wrong with the schema...

Hi Olaf,
The xsd:choice results in a featureGroup. Currently featureGroups are not automatically mapped to the database. I have
not spend time there yet. It should be doable as the java code is correctly generated and only consists of pojos. But
the featuregroups need some attention. You can enter a feature request for it though... It will be a few weeks before I
have time probably (but you never know...).

Saw your other post, for completeness also a repeating sequence is handled as featuregroup and needs new automatic ORM
mapping behavior...

Hi Olaf,
Sorry I am not able to fullfill your request.

Fyi, many people (including myself) are independent consultants. We do not receive direct payment for our support on
this forum. I am afraid that your last request does not fall within 'free' support.. I am sure you understand, ofcourse
if you are interested in direct paid support then feel free to contact me ;-).

Can you enter a feature request for automatic mapping of feature groups?

gr. Martin

OK Martin, I understand. Where should I enter the feature request? In bugzilla?
