Cannot access ObservableDirtyEntity property for a given entity in JavaFX

Granite 3.0.4

Javafx 8

I'm trying to setup property change listeners for when a given entity goes dirty but it seems the ObservableDirtyEntity is not accessible. I'm getting the following compile error "The type JavaFXDataManager.ObservableDirtyEntity is not visible"

The online documentation said I can either observe changes to entity or on the dataManager with "dataManager.dirtyProperty()"  This does work but this is for DataManager not a specific entity.  Any thoughts on this?  Does the API allow for such an observation?

my code

dataManager.dirtyEntity(del).get();

never mind figured it out.  Had to cast it to ReadOnlyBooleanProperty.
