Dear all,

I currently try to implement the following scenario, I have a page with a 
variable number of components on it. Any of the components may call a backend 
system in its model class "execute()" method.

What I try to achieve is, that if in any of these execute methods an exception 
is thrown the user gets redirected to an error page.

As far as I understand sending an redirect through the HttpServletResponse is 
not possible as the response could possibly be already commited.

I tried to figure out how "early execution" of components works but could not 
get it working, espacially I don't know how to set the appropriate 
"mgnlModelExecutionUUID" request parameter. Has anyone already tried to 
implement a similar scenario and has some pointers for me?


Kind regards

Dominik
