Do you know of a way to do this? I understand it's a little outside the scope of the current project. Side note: I am generating this schema for https://angular2-json-schema-form.firebaseapp.com (as opposed to Angular Schema Form). Angular2 supports the same schema format which is why I can use sf-java-ui, but also has a limited implementation of oneOf.\r\n\r\n","author":{"url":"https://github.com/lbispham","@type":"Person","name":"lbispham"},"datePublished":"2018-03-14T16:09:22.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/85/sf-java-ui/issues/85"}
