Custom component and access to backing bean

Question

Is it possible in JSF2 from a custom component (in method encodeBegin) to access to the FacesContext and managed beans?

Thanks you.

Answer 1

Yes. Even more, the FacesContext is available as method argument of encodeBegin() method.

Then, to access managed beans, use Application#evaluateExpressionGet().

Bean bean = (Bean) context.getApplication().evaluateExpressionGet(context, "#{beanName}", Bean.class);
