Finding the submitted UICommand in a PhaseListener

["Vahdat, Navid (external)" <Na...@external.t-mobile.de>]

I'm writing my own, little optional validation framework. In my first
approach I added a <f:param> to a command to mark validation as optional if
this command has been submitted. 

I am migrating to ADF Faces. The ADF components seem ignore <f:param>s.
Thus, I'd like to use <f:attribute>. 

Attributes are part of the UIComponent. Thus I need to find out, which
UICommand has been submitted.

Does anyone know how to find out which UICommand has been submitted from
within a PhaseListener? Basically I have access to the FacesContext and
everything it provides. 

I know that the UIViewRoot holds the list of events, which, in case of the
relevant ActionEvent, have the submitted UICommand  as their source. But I
don't know how to reach the list of queued events. They are not part of the
API.

I have tried the Decorator Pattern for the UIViewRoot, trying to extend it
by a getEvents method, by wrapping the Application and the ViewHandler.
Unfortunately this breaks everything. Either the components or the framework
must be using instanceof to see, if things are of the expected subclass.

Any suggestions would be appreciated.
Cheers,
Navid
