Error handling & redirecting from BB constructor possible ?

[Cote . Mark]

Does anybody know how to go about redirecting to an error

page from the constructor of a backing bean.

 

For example:

 

class BBean
{
     Data someData;
    
     public BBean ()
     {
           try
           {
            someData = getData();
           }
           catch(Throwable t)
           {
            // What is the code here to redirect to an error page ?
           }
     }
    
     ....
}

 

I tried using FacesContext.getCurrentInstance().getExternalContext().dispatch("error.jsp");

but I got a response already rendered error.

 

Thanks
