[Sculptor] Reference class in jar

[amphoras]

Hi,

I want to have a domain object that references another class that is:

1.  Not known to Sculptor.
2.  Does not need to be persisted.
3.  Inside a jar.

I know I can put this reference in the hand-coded subclass, but I'd like to map other properties to it (I will extend the DSL) and generate its getter/setter.  How do I create this reference in model.design?  I tried:

com.foo.common.UserInformation userInfo

Which passes validation and even generates correctly in the Base class with an import statement (very cool!), but it throws this exception during generation:

ERROR AbstractExpressionsUsingWorkflowComponent - Error in Component generator of type org.openarchitectureware.xpand2.Generator:
        EvaluationException : java.util.MissingResourceException: Property not found: db.mysql.type.com.foo.common.UserInformation

How do I tell Sculptor to not persist this class?  I tried "!persistent" for the reference, but it doesn't work.

Thanks!

If it was persistent it would be rather easy to add your own type as described in Developer's Guide.
Now it is not, and then I think the easiest is to wrap it inside a not persistent ValueObject like this:

Entity Person {
    - @UserInformationWrapper userInfo
}

ValueObject UserInformationWrapper {
    not persistent
    com.foo.common.UserInformation value
}

An alternative is to use it as you suggested. To get rid of the error you have to add
db.mysql.type.com.foo.common.UserInformation=VARCHAR
in your sculptor-generator.properties
But then you also have to do some special cases to exclude it from from hibernate and ddl generation.

PS. wiki is down, and I don't know why. You have checked out from svn and can read documentation in /fornax-cartridges-sculptor-parent/doc/AdvancedTutorial.pdf

Hmm, looks like I will have to use the wrapper.  The other method requires too much hard coding in advices to skip the generation of Hibernate and DDL snippets.

Is there a way to use inheritance instead of composition for the wrapper class?  I tried this but it doesn't like the qualified class name after "extends":

ValueObject UserInformation extends com.foo.common.UserInformation {
                        !persistent !immutable
}

Also, I see that you've fixed the wiki.  I'll look in SVN for the documentation next time.  Thanks!  :)

extension of a fully qualified class sounds like a rather useful feature. Maybe you can add a change request in jira if you need that.

OK, here is the request:  http://www.fornax-platform.org/tracker/browse/CSC-211

Thanks!

Ability to extend a fully qualified class is now implemented in trunk.
