      I'm trying to use the SPA demo in the new 6.2 page app but getting an exception - I think due to 
      transformerClass: info.magnolia.ui.form.field.transformer.multi.MultiValueSubChildrenNodePropertiesTransformer

      Caused by: java.lang.ClassCastException: info.magnolia.ui.field.ConfiguredSwitchableFieldDefinition cannot be cast to info.magnolia.ui.field.ConfiguredFieldDefinition
	at info.magnolia.ui.form.field.definition.migration.MultiValueFieldDefinitionConverter.convert(MultiValueFieldDefinitionConverter.java:67) ~[magnolia-ui-framework-compatibility-6.2-SNAPSHOT.jar:?]

	at info.magnolia.ui.form.definition.DefinitionConverter.lambda$static$2(DefinitionConverter.java:155) ~[magnolia-ui-framework-compatibility-6.2-SNAPSHOT.jar:?]

      You can see the dialog definition here:
      https://git.magnolia-cms.com/users/czimmermann/repos/website-spa-demo/browse/magnolia/light-modules/spa-website-lm/dialogs/components/Cards.yaml
       
      See attached image for appearence in 6.1
       

      I tried changing the transformer to

      `info.magnolia.ui.form.field.transformer.multi.DelegatingMultiValueFieldTransformer`

      but I still got an exception and the dialog does not open:

      Caused by: java.lang.ClassCastException: info.magnolia.ui.field.ConfiguredSwitchableFieldDefinition cannot be cast to info.magnolia.ui.field.ConfiguredFieldDefinition
