I'm getting the error "java.lang.reflect.InvocationTargetException". Spent hours trawling through forums. The produce the FXML code I used Scene Builder and everything SEEMS to be in working order. Where is the issue coming from? and how can I stop it in the future?
Thanks for the help!

Answer 1

If you check the list of imports in your FXML file you have:
<?import com.gluonhq.charm.glisten.control.TextField?>
<?import javafx.geometry.Insets?>
...
So unless you are creating a Gluon Mobile project, your JavaFX application will not include the Gluon Mobile library, and it will fail to find the com.gluonhq.charm.glisten.control.TextField control, throwing the InvocationTargetException.
You just need to use the JavaFX built-in control, from the Controls tab:
