A4j exception handling.

[quartilan]

Is there a way to handle unchecked exception so I can give an FacesMessage on the page that was responsible for the exception.

I don't want to redirect to an error page. An example would be "OptimisticLockException".

I found for MyFaces that they do something with "ApplicationListenerImpl" but this doesn't exist for richfaces.

I could use try catch for this kind of exception but would prefer an other solution.

Thx in advance.

Hi,

I think you can use MyFaces solution together with RichFaces, or do you need to use RI JSF?

I can't use myfaces. It must all be richfaces :-s

You could try - catch every exception in managed beans, and then add the message you want with FacesContext.addMessage method (these is standard JSF so will work with myfaces and SUN RI implementations). Here is the API:

http://developers.sun.com/docs/jscreator/apis/jsf/javax/faces/context/FacesContext.html#addMessage%28java.lang.String,%20javax.faces.application.FacesMessage%29

Thx but I'm looking for a way so I don't need add a try catch in my beans.

Something like a filter.

But thx for your answer.
