Hello.

I am trying to migrate my code from RF 3.3. I have a popup panel with dynamically generated content.

ValueExpression okButtonValueExpression = expressionFactory
        .createValueExpression(
                elContext,
                "if (#{facesContext.maximumSeverity==null}) "
                        + "#{rich:component('popup')}.hide();",
                String.class);
okButton.setValueExpression("oncomplete",
        okButtonValueExpression);
                    
ValueExpression cancelButtonValueExpression = expressionFactory
        .createValueExpression(elContext,
                "#{rich:component('popup')}.hide();",
                String.class);
cancelButton.setValueExpression("onclick", cancelButtonValueExpression);

I get the following exception:

Caused by: javax.faces.el.EvaluationException: javax.el.ELException: Function 'rich:component' not found

    at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:102)

    at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:102)

What is the right way to do that with RF 4?
