Hi there,

I've a problem with my application (it uses Seam and ICEfaces) in a special use 
case:

There is the possibility to attach files for an entity. Those files are stored 
on disk. The file upload is realized using a component (ice:inputFile) from 
ICEfaces. This component renders an iframe that contains a form. This iframe is 
rendered in the form that is used to display (and to change) the entity. So the 
page contains an "outer" and an "inner" form. Hitting "upload" this inner form 
is submitted and handled by a special Servlet by ICEfaces. It invokes a method 
in a manager bean, passing over a object that contains information about the 
uploaded file. The file is stored by my application.

This works fine. The page is rerendered and the list, that shows all attached 
files, shows the new file. The problem now is that I can click any button or 
link (whether it navigates to a new page or invokes an action), I get this 
exception in the server.log:

to: /error.xhtml

Almost directly after the beginning of the new LifeCycle, a stateful bean can't 
be found. And I don't know why. I assume that it has to do something with this 
upload because all page actions work fine until I upload a file.

I'm pretty sure that I've done a mistake in my application since it worked 
before. So I think I've done something to cause this exception. But I can't 
remember of a change in my application that could cause this.

Perhaps somebody knows or sees a correlation between the upload request and the 
(empty) StatefulCache? BTW: Does somebody know how to find out the name of the 
bean that should be activated? I can't find any information about this bean's 
id in the log.

Thanks in advance
Newlukai
