Hello, I am new to adf and EJB/EclipseLink, so I have a question
May be my question is not the same as a topic starter had, But I have quite close issue with Stateful session beans and related bean life exceptions.
I have app with Model and ViewController parts (as created using default Jdev master for Fusion Web Applications). In Model I have a Stateful bean running some businesses logic. On View I have one of the Statful ejb bean methods exposed through data control as adf form with input field and button action like "#{bindings.fireMdxQuery.execute}", so in some cases this method can throw exception, and Stateful bean will be removed.
Method signature for local bean interface looks like:
public void fireMdxQuery(String query) throws ConnectionException, OperationException;
For first call example I could achieve first - normal exception stacktrace, and then on second bean call -      
java.lang.reflect.InvocationTargetException
Bean has been deleted.
Caused by: javax.ejb.NoSuchEJBException: Bean has been deleted.
Could you please provide,what is the best way to determine, that statefull bean has been removed, to have ability to redirect user to some special place or running some businesses logic in such case? Am I expected to use managed bean, use code like
OperationBinding method = getBindings().getOperationBinding("exposed_stateful_ejb_method_name");
method.getParamsMap().put("param", value);
method.execute();
List<Exception> list = method.getErrors();
and every time checking for javax.ejb.NoSuchEJBException?
Thank you.
