Even though I don't understand why someone would need a listener
for the If component, you can have something like:

<span jwcid="@InvokeListener" listener="..." parameters="..."/>
<span jwcid="@If" condition="..."/>

Re: Is it possible to pass parameters to the If listener ?

I guess he means something else, which is the listener embedded in the 
if component.
I guess also you don"t need any parameters there, beacuase the listener 
can get all the information from the current state of the 
component/object. the listener is not deferred, and thus will be called 
just before the rendering of the if. any parameter you could gain access 
to any parameter the if could have accessed.
The only use I could think of using such a parameter is if you want to 
use the same listener for several if's.
so don"t :)
Cheers,
Ron
