[jwt-dev] Re: A question about extension custom model in JWT

[Marc Dutoo <marc.dutoo@xxxxxxxxxxx>]

Hi Kim

Welcom to the Java Workflow Tooling community !

I urge to send your questions to the mailing list ( Java Workflow 
Toolbox <jwt-dev@xxxxxxxxxxx> ), so everyone can see them.

As I understand, you are using EMF to extend the model rather than JWT's 
Aspects model extensions. So the following excerpts of 
http://wiki.eclipse.org/JWT_Metamodel_Extension apply in your case :

"

   * extend an existing type of the model with your own type. This is
     only interesting to create well identified subtypes, i.e. that
     could have been provided in the base model beforehand. If it is
     the case, please consider contributing it to JWT's core metamodel.
     To enable child extenders, extensibleProviderFactory="true" has to
     be set on the genModel package of the EMF class you want to extend
     (OK for jwt-we-conf-model, TODO 20100112 regenerate JWT
     metamodel), and on your side you have to set
     childCreationExtenders="true" on the genModel package of your
     extending EMF class. See an example in
     jwt-we-plugins/jwt-we-sample-aspectchildextenders and Ed Merks'
     blog at
     http://ed-merks.blogspot.com/2008/01/creating-children-you-didnt-know.html
     .

Hoping this last link will help you.
