Problem with Hibernate xml codegeneration

[ghost]

Hi there

As written in https://groups.google.com/forum/#!topic/querydsl/_uUy9vrblrg this is a new bug report.

With QueryDSL 2.7.0, the Hibernate to XML code generator generates not compileable sources.

he problem is the following mapping in customer.hbm.xml:

    <set name="contacts" cascade="all-delete-orphan" order-by="value" fetch="join">
        <key column="customer_id"/>
        <one-to-many class="CustomerContact"/>
    </set>

This is generated in QCustomer.java as

public final SetPath<Contact, Path> contacts = this.<Contact, Path>createSet("contacts", Contact.class, Path.class);

This is leading to compiler errors, as the Path class does not extend the SimpleExpression class, it is just an interface. What about the following:

public final SetPath<Contact, SimplePath> contacts = this.<Contact, SimplePath>createSet("contacts", Contact.class, SimplePath.class);

Could you post the sources of Customer, Contact and CustomerContact? I need probably also the mapping parts of these classes to be able to reproduce the problem.

Hi there

Here are the sources:

Customer.java

public class Customer extends Person<CustomerContact, CustomerHistory> implements UDFSupport {

private Map<String, UserDefinedField> udf = new HashMap<String, UserDefinedField>();

}

    return udf;
}

public void setUdf(Map<String, UserDefinedField> udf) {
    this.udf = udf;
}

}

I checked every Version from 2.5 to 2.7. The problem can be reproduced with every version.

I need all the mapping files for the files you provide. Also there seem to be some type parameters for Person missing.

Looks like incomplete mapping information, but I really need more data to provide a definite answer.

Hi there

The sources and mapping files can be downloaded here:

http://mogwai.svn.sourceforge.net/viewvc/mogwai/trunk/mogwai/jee-ddd/

See the domain maven module for java classes, the infrastructure module for mapping files. You can compile it out of the box using mvn clean to reproduce the problem.

Mirko

Could you point me directly to the HBM files and post the error you get when building mogwai? I couldn't find Hibernate mapping files in the infrastructure project and the build succeeded.

[timowest]

Any progress on this issue from your side?

[mirkosertic]

Please check again, i forgot to commit some stuff.. Just run mvn clean compile on the parent pom.

Released in 2.7.3
