J'ai modifier le transformer de wikitty qui transforme un modele en un autre. Il étendait ObjectModelTransformerToJava, mais comme il ne génère pas de java, il est mieux d'étendre seulement ObjectModelTransformer. Autre point, pour utiliser un simple ObjectModel au lieu d'un JavaGenerator, j'ai du copier/coller beaucoup beaucoup de code. Essentiellement toutes les méthodes cloneXXX() Je pense qu'il y aurait une factorisation possible sur un transformer qui fait de la copie, mais pas typé Java...
