I don't know enough of JavaFX to tell you for sure how to address this. I'd suggest not removing the caching (fieldValues.get(fields);) and instead deal with the dependencies differently.

  • You can extend StringBinding and use .bind and .unbind to "manually" deal with the dependencies. (this is probably not a good approach)
  • You can extend a different binding (ObjectBinding?) and have it handle changes to the referenced entry. In this scenario, the StringBinding has this ObjectBinding among its dependencies instead of the referenced bibentry's getObservables().
  • At least superficially this seems like a good application for EasyBind because,
    1. You can create an optional binding, e.g., entry.getFieldBinding(StandardField.CROSSREF)
      1. This means you can create an OptionalBinding<BibEntry> referencedBibEntry
    2. It should be possible to keep an observableArrayList with extractor (FXCollections.observableArrayList(BibEntry::getObservables)) updated with the ifValuePresent method of the OptionalBinding<BibEntry> EasyBind.subscribe. That should keep the list up-to-date when the referenced BibEntry is changed/removed and when the observables in the referenced bibEntry.getObservables are modified
    3. This list should now be usable as a dependency

Note that the two last approaches should be used or called from the constructor since they will update on changes to the referenced BibEntry.

I'd appreciate it if someone with more experience of JavaFX chimes in with opinions 😛
