Trouble figuring how to navigate between views in the same window.

[THC Bigshooter]

Hi there!

I've been trying to follow the tutorial number 2 (http://www.guigarage.com/2014/05/datafx-tutorial-2/), but I can't seem to find the method startInStage(primaryStage), how come? I'am having a lot of trouble navigating between views, so if anyone has a simple example, it would be great :-)

Cheers!

What version  of JavaFX are you using? You should use 8.0 that is released at maven central: http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22io.datafx%22

With 8.0 the package name has changed. Now all packages start with io.datafx.* but all the rest should be the same.

[THC Bigshooter]

I use e(fx)clise plugin at the moment, that should be 8.0.

Do you have Datafx include to project?
If you included datafx-controller remove. This libary remove some method from flow.
Hendrik Ebbers this is possible to flow on click table cell, if yes can you take me example?

[Hendrik Ebbers]

Hi,

I created a description how DataFX can be added to an application: http://www.guigarage.com/2015/01/set-datafx-application/

Please check your setup based on this tutorial. Let us know if you still have problems :)

[THC Bigshooter]

I've now done the complete setup, and I am now able to locate the startInStage-method. I've followed the tutorial 2, but it won't seem to function.

public class MainApp extends Application {

private Stage primaryStage;

private AnchorPane rootLayout;

@Override

public void start(Stage primaryStage) throws Exception {

new Flow(RootController.class).startInStage(primaryStage);

}

public static void main(String[] args) {

launch(args);

}

}

@FXMLController("/view/StandardView.fxml")

public class RootController {

@FXML

@LinkAction(AdministrateRentalsController.class)

private Button RentalsAdministration;

}

@FXMLController("/view/AdministrateRentalsView.fxml")

public class AdministrateRentalsController {

@FXML

@LinkAction(RootController.class)

private Button backToStartView;

}

The views should be spot on, I just use the fx:id as the name of the buttons. Right now nothing happens when I click on them.

[THC Bigshooter]

It actually looks like it is rendering the further version. The stage title is still the same, and I can't change it in main. It tell me that there are errors in the project, even it doesn't locate anyone.

Oh, I forgot to clean my solution, now I get this error:

Error: Could not find or load main class application.MainApp

[THC Bigshooter]

Sorry for all the posts. I managed to clean up, and now get this error.

Hi,

as described in the tutorial you need the transitive dependencies for DataFX. In your case javax.inject is missing. You can download it here: http://search.maven.org/#artifactdetails%7Cjavax.inject%7Cjavax.inject%7C1%7Cjar

[THC Bigshooter]

Oh, that's odd. Wasn't it enough to add the injection jar described in the tutorial? I've done that.

[Hendrik Ebbers]

You need the injection jar only if you want to use dependency injection. This is a new feature for DataFX that will be described with the next tutorial. Normally you donÄt need it. But when adding the jar you need to add it dependencies, too.

Now I understand, I see that i'll miss a few more, where can I find them?

Am Donnerstag, 29. Januar 2015 15:19:55 UTC+1 schrieb Hendrik Ebbers:

[Hendrik Ebbers]

You can download them all at Maven Central. Have a look at the pom.xml files of DataFX modules and its dependencies at Maven central. In this files is a section <dependencies>….</dependencies> that include all needed dependencies. All have defined a group-id, artifact-id and version and can be found at maven central.

[THC Bigshooter]

Oh okay, and it's enough just to add them to build path as well?

[THC Bigshooter]

Thanks! Now I am able to see the first stage, but when I click the button nothing happens? I've followed your tutorial completely.

[Hendrik Ebbers]

add the following method to you controllers:

@PostConstruct

public void init() {

System.out.println(„Value of the Button „ + RentalsAdministration);

}

if RentalsAdministration is null you have an problem with the FXML or fx:id.

you can find the original sources of the tutorials here: https://bitbucket.org/datafx/datafx/src/2ce2f5b372a179eb318fae023f13ee74f49544ef/modules/tutorials/?at=default

They should all work. You can compare them with your code

Hendrik

[THC Bigshooter]

Oh, it seems like there a difference in the tutorial compared to the link? Before the class definition of the controller you have @ViewController in the code, but in the tutorial you have @FXMLController? If I try to replace FXMLController with ViewController it can't seem to find it.

[THC Bigshooter]

What are you refering to with RentalsAdministration?

Am Donnerstag, 29. Januar 2015 15:59:00 UTC+1 schrieb Hendrik Ebbers:

[Hendrik Ebbers]

Yes,

Next week DataFX 8 will come and in this version some annotation names changed. Therefore I already changed the tutorials in the last version of the code. The link was wrong. Here is the right one: https://bitbucket.org/datafx/datafx/src/2d65ac12083005354a7517ee14a33d799843e650/modules/tutorials/?at=8.0

[THC Bigshooter]

Still doesn't seem to work, even though I copied every single line of code :/

[Hendrik Ebbers]

Any errors or messages on the console?

[THC Bigshooter]

Nothing at all, the button just doesn't react.

[THC Bigshooter]

I tried to add the postContruct to the View2Controller to make it print something when called, but the button doesn't seem to call it. If you set the View2Controller to the startup view, it work thoug,h.

I've now tried to copy Toturial 3 as well, and same result, no reaction when pressen the button.

Can you create zip and upload it?

There you go, it's the tutorial 3 :)

Will have a look at it later.

[THC Bigshooter]

Thanks! I really appreciate it!

[THC Bigshooter]

I tried to contact one of my professors to look at it, and he couldn't figure it out either, so I'm pretty much relying on you guys :D

[Hendrik Ebbers]

Hi, you are mixing dependencies with different version. When using DataFX you should always use the same version for all DataFX dependencies. 

In your project you have flow-8.0.7 and injection-8.0 for example

Use 8.0 for all DataFX dependencies.

[THC Bigshooter]

Oh thanks! Can you provide me a link for those? I must have mixed up

[THC Bigshooter]

I used this link from the tutorial, that seems to be the 8.0.7: http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22io.datafx%22

[THC Bigshooter]

Thanks! It seems to work now! Why should I use 8.0 instead of 8.0.7 btw?

[Hendrik Ebbers]

8.0.7. is a wrong / broken release and I don't know how to remove it from maven central.
