JavaFX and Scene Builder clip scene edges despite specifying USE_COMPUTED_SIZE

I'm using Scene Builder (v11.0.0) to create FXML files for scenes in JavaFX (v12) but, despite instructing all containers to USE_COMPUTED_SIZE for the preferred widths and heights, the rendered scenes (as seen in Scene Builder and also when run as a JavaFX application which loads those FXML files) are being clipped at the right and bottom edges so that bits of nodes are chopped off.
And in Scene Builder it seems that the renderer must know that the scene won't fit the allowed bounds because the editor shows blue boundary markers which are clearly some way beyond the rendered rectangle.
View in Scene Builder
The view in Scene Builder shows that more space is needed at the bottom in order to give the buttons sufficient space (their bottom edge, and the lower edge of the TitledPane is missing). And more space is needed at the right in order to fit the right edges of the DatePicker and TitledPane. The blue boundary markers show clearly where the actual content ends, so it's not clear why the display area is being calculated to be several pixels shorter than this.
View of running Java application
Once the FXML files are used to populate a window in a JavaFX application, the same thing is seen: the calculated size for the window is a number of pixels too few to fit the whole scene correctly.
If the blue boundary markers have correctly been calculated to show that extra display area width and height are needed, how do I tell the FXML to require this additional space when rendering?
Is this a known bug/limitation in Scene Builder, FXML, or JavaFX. Or is there something more I need to do beyond just selecting USE_COMPUTED_SIZE for the preferred dimensions?
In order to make this explicit, see the example FXML below which displays the problem illustrated.

<children>
<Label text="Label" />
<DatePicker />
</children>
</VBox>

This does appear to be a bug in JavaFX, specifically DatePicker, as this simple example can reproduce the problem:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.DatePicker;
import javafx.scene.layout.Region;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
VBox root = new VBox(new DatePicker());
// Problem shows up when using USE_COMPUTED_SIZE (the default) as well
root.setMinSize(Region.USE_PREF_SIZE, Region.USE_PREF_SIZE);
root.setMaxSize(Region.USE_PREF_SIZE, Region.USE_PREF_SIZE);
primaryStage.setScene(new Scene(root));
primaryStage.show();
}
}
Resulting in:
Note: It does not seem to matter what parent the DatePicker is put in. Nor does the problem appear with other controls.
A workaround to this issue appears to be calling Window.sizeToScene() after calling show(). I don't understand why that would make a difference, but it does. Unfortunately, this will only help in the real application, not in Scene Builder.

FXML: ImageViews showing up in SceneBuilder but not in the actual app

I'm trying to write a simple Java app for modifying and visualizing logic circuits by dragging gates and connections about. I'm using SceneBuilder to put the interface together. Right now, I'm stuck at getting the available basic logic gates to display in their proper bar and respond to being interacted with. More accurately, I'm trying to get one gate to just display some console output, to confirm that the GUI-logic connection is working.
The biggest problem I'm having is that the ImageViews of the gates, possibly along with some other FXML elements, refuse to display in the actual compiled app for some reason, even though they work and react correctly in SceneBuilder and in its "Preview" feature.
I had to do some experimenting with wrapping them in various other FXML elements which I didn't really understand because apparently ImageWiew doesn't have a onDragDetected() method, even though the text input field for it is available in SceneBuilder. The intended work-in-progress app layout can be seen plainly enough directly from SceneBuilder on the first picture. Compare with the second one, which is of the actual running application.
Possibly relevant code:
Main.java
package main;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("RootLayout.fxml"));
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(root, 640, 450));
primaryStage.show();
}
public static void main(String[] args) throws Exception {

I thus need to know:
Why are those gates(or at least one) not displaying as intended? And what's with the ScrollPane, why is it not displaying its sliders as it is in SceneBuilder? What things do I need to set up differently or wiggle with to get those gates to show up and interact correctly?

After a bit of random crapshooting, I found a solution.
First, I looked into View->Show Sample Controller Skeleton. There, I noticed that the handleDragDetectedNAND() method does not have any modifier, whereas mine had private, copied early from some tutorial or the other. I removed the modifier and the application now works. If anyone who passes by cared to explain why this is the case(I have no idea and no time to research, deadline's fast approaching), the value of this answer would rise significantly.

Be sure all images inside of src folder. (tested)

JavaFx SceneBuilder 2.0 not resolving custom controls

I have a custom JavaFx control that renders in my application. But, I can't get SceneBuilder to understand it.
I have CustomTextField.java / CustomTextField.fxml. CustomTextField inherits from UserControl, as defined here, but my scene builder problem happens with any custom control that I create.
First, I had to change my import statement to be a wildcard. From
<import sample.CustomTextField>
to
<import sample.*>
otherwise, scenebuilder threw an exception / showed a stacktrace indicating that the source file couldn't be found. I have no idea why this was necessary, but it seemed to work, so I kept moving.
I had read that you to specify a scenebuilder-classpath-element in the fxml file as well. So, i tried every combination I could think of:
<?scenebuilder-classpath-element ../../bin?>
<?scenebuilder-classpath-element ../../out?>
<?scenebuilder-classpath-element ../../../out?>
<?scenebuilder-classpath-element ./?>
<?scenebuilder-classpath-element ../../../../../target/classes?>
My issue is that the custom control does not render in Scene Builder. SElecting it in the hiearchy tree, it indicates "Selection contains unresolved reference". If I can't drag/drop the custom control around, that's acceptable. However, I really want to render this in Scene Builder and lay out other stuff.
I am using IntelliJ IDEA 14, and Scene Builder 2.0
sample.fxml:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import sample.*?>
<?scenebuilder-classpath-element ../../bin?>
<?scenebuilder-classpath-element ../../out?>
<?scenebuilder-classpath-element ../../../out?>
<?scenebuilder-classpath-element ./?>
<?scenebuilder-classpath-element ../../../../../target/classes?>

</children>
</Pane>

I'm able to load custom classes. We got it to work by building a .jar with the custom classes, then in SceneBuilder, go to the settings icon next to searching the library and import custom library. Then find your .jar. Maybe you could do the same thing with .class files?
Here's the import statement in the .fxml:
<?import com.rlsciences.autoredact.view.ItemsTableView?>
Here's where I'm using it in the .fxml:
<ItemsTableView id="searchResultsTableView" fx:id="searchResultsTableView" fixedCellSize="20.0" styleClass="compact-table" VBox.vgrow="ALWAYS">
Here's the class definition:
package com.rlsciences.autoredact.view;
public class ItemsTableView<S> extends TableView<S>

Getting an FXML window to open when running a java file

I am currently trying to build a picture viewing program using java and an FXML window. I have had a fiddle about - getting to know FXMLs and accessing them from a program and was able to get buttons to disappear and reappear - but upon adapting said code for this picture viewer, I found that the FXML panel wouldn't open upon running the file. There are no errors/warnings besides warnings about (as yet) unused libraries being declared. Upon start up, there's no error messages, no text boxes and no outputs to the terminal so I can't supply anything from there. The code is as follows:
package practice1;
import javafx.application.Application;
import javafx.stage.Stage;
import java.io.IOException;
import javax.imageio.*;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.io.*;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.*;
import javafx.scene.image.ImageView;
import javafx.scene.image.*;
import java.awt.image.BufferedImage;
public class MainProgram extends Application{
public void start(Stage stage) {
try {
FXMLLoader fxmlLoader = new FXMLLoader();
String viewerFxml = "WindowPanel.fxml";
AnchorPane page = (AnchorPane)fxmlLoader.load(
this.getClass().getResource(viewerFxml).openStream());
Scene scene = new Scene(page);
stage.setScene(scene);
stage.show();
} catch (IOException ex) {
Logger.getLogger(this.getClass().getName()).log(Level.SEVERE, null, ex);
System.exit(1);
}
}
public static void main(String args[]) {
launch(args);
System.exit(0);
}
}

</AnchorPane>
The file "Picture1.png" is located in the workspace with the position being:
WorkspaceA/Practice1/scr/practice1/Picture1.png

Background
The # notation is used in JavaFX to specify a relative location which is "assumed to be located at a path relative to the current FXML file".
What is Wrong
You load the FXML as a stream using the following code:
AnchorPane page = (AnchorPane)fxmlLoader.load(
this.getClass().getResource(viewerFxml).openStream());
A steam is not a location, so there is no concept of locations relative to the stream.
If I run your application locally, I will get a stack trace where it cannot find the picture file (here is just the last portion of it):
Caused by: java.lang.IllegalArgumentException: Invalid URL or resource not found
at javafx.scene.image.Image.validateUrl(Image.java:1081)
... 18 more
How to fix it
Set the location in the loader prior to loading the FXML:
fxmlLoader.setLocation(getClass().getResource(viewerFxml));
AnchorPane page = fxmlLoader.load();
The loader will then be able to resolve the relative reference to your picture file.
Check your directory structure and build output
This may or may not be an issue for you.
You specify your image using the location specifier:
<Image url="#Picture1.png" />
Which tells the FXMLLoader to look for Picture1.png at the same location it got the FXML from; e.g. if you loaded the FXML from the filesystem, the image would be in the same folder on the filesystem as the FXML - similarly if you load the FXML from a jar, the image should be on the same path within the jar as your FXML was retrieved from.
You state that you place your picture at: WorkspaceA/Practice1/scr/practice1/Picture1.png. I'm not sure what that location is, but if it is the same location as your MainProgram.java source, your MyController.java source, WindowPanel.fxml and if your build system is set to copy the image and fxml over to the compile and packaging target directory, then it will work fine - if it's not, you will need to move the image to the appropriate source location.
