Using custom datatype from another module/add-on

Hi,

I have the same problem with the custom datatypes as described by @bank. Here’s the use-case I have:

The entity soft reference addon: GitHub - mariodavid/jmix-entity-soft-reference at cuba-compatability · GitHub (branch cuba-compatability).

There I have two modules:

The CUBA compatibility module jmix-entity-soft-reference-cuba has a dependency on the entity-soft-reference module as you mentioned:

@Configuration
@ComponentScan
@ConfigurationPropertiesScan
@JmixModule(dependsOn = {
        EclipselinkConfiguration.class,
        UiConfiguration.class,
        SoftReferenceConfiguration.class
})
@PropertySource(name = "de.diedavids.jmix.softreference.cuba", value = "classpath:/de/diedavids/jmix/softreference/cuba/module.properties")
public class SoftReferenceCubaConfiguration {

// ....
}

Additionally, I added the JPA entity enhancing information in the cuba module:

    entitiesEnhancing {
        jpaConverters = ['de.diedavids.jmix.softreference.entity.SoftReferenceConverter']
    }

In the jmix-entity-soft-reference module there is a custom datatype SoftReference and the jmix-entity-soft-reference-cuba module has the old CUBA custom datatype: EntitySoftReference.

Now I have set up an integration test in the cuba module, that has a Document entity that contains now references to both datatypes.

The test fails as the application context cannot be started:
