org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active contexts for scope type javax.faces.flow.FlowScoped

问题

I´m trying to develop a simple example of new functionality of JSF 2.2, @FlowScope, I develop it with eclipse luna, glassfish 4.0, I guess the code is right cause I caught it on the web, probably the error is with the configuration of the project. Could anyone give me an Idea of what could be? Pleas ask me further information if it´s hard to understand with these few information but actually I don´t know what more I can write to help and this is my first question on stackoverflow.

public class NestedFlowBuilder implements Serializable {

    private static final long serialVersionUID = 1L;    
    @Produces
    @FlowDefinition
    public Flow defineCallingFlow
    (@FlowBuilderParameter FlowBuilder flowBuilder) {
    String flowId = "secondJavaFlow";
    flowBuilder.id("", flowId);
    flowBuilder.viewNode(flowId, "/java-calling-flow/start-page.xhtml")
    .markAsStartNode();
    flowBuilder.viewNode("results", 
    "/java-calling-flow/results-page.xhtml");
    flowBuilder.returnNode("return").fromOutcome("/return-page-for-java-calling-flow");   
    flowBuilder.returnNode("home").fromOutcome("/index");
    flowBuilder.flowCallNode("go-to-nested")
    .flowReference("", "thirdJavaFlow")
    .outboundParameter("paramForNestedFlow", 
    "#{javaCallingFlowBean.param1}");
    return(flowBuilder.getFlow());
    }



    @Produces
    @FlowDefinition
    public Flow defineNestedFlow
    (@FlowBuilderParameter FlowBuilder flowBuilder) {
    String flowId = "thirdJavaFlow";
    flowBuilder.id("", flowId);
    flowBuilder.viewNode(flowId, 
    "/java-nested-flow/start-page.xhtml")
    .markAsStartNode();
    flowBuilder.viewNode("results", 
    "/java-nested-flow/results-page.xhtml");
    flowBuilder.returnNode("return-to-previous-start")
    .fromOutcome("secondJavaFlow"); 
    flowBuilder.returnNode("return-to-previous-results")
    .fromOutcome("results");
    flowBuilder.inboundParameter("paramForNestedFlow", 
    "#{javaNestedFlowBean.param3}");
    return(flowBuilder.getFlow());
    }
