Can't return from Flow

I created a simple flow in JSF but I can't exit at the 2. page or 3. page. I use @FlowDefinition to specify start page and end/return page.

Error message: Unable to find matching navigation case with from-view-id '/flowname/step3.xhtml' for action 'exit' with outcome 'exit'

I use WildFly 16 on Ubuntu 18.04

    <body jsf:id="body">

            <h:commandButton value="Click here!" action="flowName"/>

FlowName.java

public class FlowName {
    public static final String NAME = "flowName";
    public static final String EXIT = "exit";

    private static final String START_PATH = "/flowname/start.xhtml";
    private static final String EXIT_CMD = "/home";

    @Produces
    @FlowDefinition
    public Flow defineFlow(@FlowBuilderParameter FlowBuilder flowBuilder) {

        flowBuilder.id("", NAME);
        //start the flow
        flowBuilder.viewNode(NAME, START_PATH).markAsStartNode();

        //exit from flow
        flowBuilder.returnNode(EXIT).fromOutcome(EXIT_CMD);

        return flowBuilder.getFlow();
    }
}

I tried to exit at start page and that was successful.

Solution

It don't work well, because the name of the flow pages don't start with the flow name. (With same config)

flowName/
    flowName-start.xhtml (or flowName.xhtml the default start page)
    flowName-step2.xhtml
    ...

The default return page e.g.: flowName-return.xhtml Don't need any config (xml or annotated method) for default start or default return page. See more
