Use variable in activiti

Question

I am playing around with vaadin and activity, and was wondering how to use a variable, in my vaadin code, in my activiti script. For example my vaadin code is as following

TextField field = new TextField("Enter Name: ");
Button button = new Button("Click Me: ");
button.addClickListener(new Button.ClickListener() {

    @Override
    public void buttonClick(ClickEvent event) {

        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();


        RepositoryService repositoryService = processEngine.getRepositoryService();
        repositoryService.createDeployment()
            .addClasspathResource("hello_world.bpmn20.xml")
            .deploy();

        HashMap<String, Object> v = new HashMap<String, Object> ();
        v.put("name", field.getValue());

        RuntimeService runtimeService = processEngine.getRuntimeService();
        runtimeService.startProcessInstanceByKey("myProcess", v);



    }
});

and my groovy script in activiti is

System.out.println("Hello " + v);

I tried to use the HashMap but the script still does not recognize my variable. How do I use my code variables in an activiti script?

Answer 1

It looks like you're setting up a variable called name

    v.put("name", field.getValue());

But then printing a variable called v

System.out.println("Hello " + v);

If you change this to (making it a bit more Groovy in the process)

println "Hello $name"

It should work!
