Exceptions throw when trying to use JFXTextField in Scenebuilder 16

[ghost]

Trying to use in scenebuilder and the jar analysis report includes this:

Not a fix but helps maybe: I had other problems using Scene Builder 16 and switched back to 15.

This is a problem with scenebuilder, you have to downgrade.

What I tend to do when SceneBuilder doesn't support a custom component is create and initialize those components in code instead of FXML... not ideal but it does let you continue to use SB for other stuff.

[CTaszus]

Sometimes, SB is missing a library for a custom component. I think SB cannot resolve dependencies. My SOP is:

1. Make sure a zero-argument-constructor exists
2. Check any static and default constructor lines against uncommon objects

Edit: But as I wrote above this is a different problem. For this thread, a SB downgrade should to the job.
