Subject: ExceptionHandling with JSF and Tiles

 

Hi all,

 

I am still confused about Exception Handling. I know that this has been discussed on many threads but I don't know how to handle exceptions 

outside Actions/ActionListeners. 

 

My setup is MyFaces 1.1.1 and Tiles with the JspTilesViewHandlerImpl.

 

I can create FacesMessages and forward to any outcome page when an exception occurs in an action/actionListener. This is working fine and no problem.

  

I don't know how to handle serious errors in BackingBean constructors or setters.

I tried to catch them and re-throw them as FacesExceptions but my error pages (defined in web.xml) are not displayed.  

Instead of the error page the original requested tiles template is partly processed.

A ServletException is displayed in place of the tiles-part that caused the error.

e.g. ServletException in:/xxx.jsp] Cannot get value for expression '#{ABackingBean.aValue}'

   

How do others handle exceptions with myFaces and Tiles?

Are there any best practices?

 

Any help would be greatly appreciated.

Michael
