Control Bus bug with BenaFactory

[Cleric]

Hello, Mark, Oleg & Dave
I've caught some bugs in Control Bus components.

1. If I using the <groovy:control-bus input-channel="controlBusChannel"/>, GroovyControlBusFactoryBean "scolded" me that I have some abstract beans. So, I think the code of ManagedBeansScriptVariableGenerator.generateScript Variables must be like:

for (String name : this.beanFactory.getBeanDefinitionNames()) {
      BeanDefinition def = this.beanFactory.getBeanDefinition(name); //THIS
      if (def.isAbstract()) continue;                  // AND THIS
      Object bean = this.beanFactory.getBean(name);

2. I cant access to FactroyBeans directly from SpEL. For example:

<transformer input-channel="refreshGlobalSettingsChannel" output-channel="controlBusChannel" expression="'@&amp;globalSettings.refresh()'"/>

Because the SpEL doesn't understand sombol "&". No words...

And some question out of thread:
1. How can I access directly to BeanFactory(ApplicationContext) from SpEL?
2. How can I make my singleton Beans refreshable?
I've wrote some class:

@ManagedResource
class RefreshableFactoryBean<T> implements FactoryBean<T>, InitializingBean {

    @Autowired
    BeanFactory beanFactory

    ExpressionFactoryBean delegate

    volatile T object

    Class<T> objectType

    String expressionString

    EvaluationContext evaluationContext

    @ManagedOperation
    void refresh() {
        if (delegate) object = delegate.object.getValue(evaluationContext)
    }

    boolean isSingleton() {
        return true
    }

    void afterPropertiesSet() {
        if (expressionString) {
            delegate = new ExpressionFactoryBean(expressionString)
            delegate.afterPropertiesSet()
            evaluationContext = new StandardEvaluationContext()
            evaluationContext.beanResolver = new BeanFactoryResolver(beanFactory)
        }
        refresh()
    }
}

But I hope there are some elegant solutions in the Spring...

thanks in advance,

P.S. Sorry for mistake in the name of Thread. Disgraced...
