DataFX - is a JavaFX frameworks that provides additional features to create MVC based applications in JavaFX by providing routing and a context for CDI.

Hopefully some perspective from my newbie eyes is useful.

I've gone through the tutorials and fixed anything I've seen that could use fixing.

I also suggested where things could be more clear. Thanks for the great work.

This simplifies testing of DataFX controllers a bit as the example below shows. Previously we had no possibility to use startInStage() and fetch the FlowHandler which was used in this method.

Note: <T extends Parent> in void startInStage(Stage stage, FlowContainer<T> container), because Scene's constructor requires a Parent.

This is based on an issue at https://github.com/TestFX/TestFX/issues/207.

@Override
public void start(Stage stage) throws Exception {
    Flow flow = new Flow(ManageCtrl.class);

    FlowHandler handler = flow.createHandler();
    handler.startInStage(stage);

    FlowView view = handler.getCurrentView();
    controller = (ManageCtrl) view.getViewContext().getController();
}

The complete example is here: https://gist.github.com/hastebrot/0d56eae0cae9e76c481b

Please let me know if something needs to be changed in this PR.

hi, when I used actionHandler.navigateBack() to go back to the previous viewController, and press some button to fire some action, but got exception:Can't find an action with id xxx.

I am using the suggested latest version of Datafx:flow from the maven central repository:

https://mvnrepository.com/artifact/io.datafx/flow/8.0.1

.. and try to run this using Gradle 6.0 with a JDK version of 13.0.1

Added a license file allowing other GitHub users to consider this project as Open Source. The license file is the same as specified in the Maven repository

What is the current status of the project? And what is its official site?

I've posted this question about the project's up-to-date information on SO, but haven't received any answers within a month, so I've decided to ask here. Feel free to answer on SO, if you find it more suitable.

How are the private fields of the class FlowHandler

private SimpleObjectProperty<BeforeFlowActionHandler> beforeFlowActionHandler;
private SimpleObjectProperty<AfterFlowActionHandler> afterFlowActionHandler;
private SimpleObjectProperty<VetoableBeforeFlowActionHandler> vetoableBeforeFlowActionHandler;
private SimpleObjectProperty<VetoHandler> vetoHandler;

populated and used in datafx? I would like to fire an event after a flow has taken place having access to the actionId. Are they accessed via reflection or just idle at the moment? Any chance we get some getters/setters?
