JBoss Seam actually extends the JSF EL allowing multiple input parameters

Thanks for your reply Lucas. I haven’t read anything you wrote that is completely useless.
You might also want to take a look at “A Second Example” in “Enterprise Java Technologies Tech Tips” of January 2007:

It is about “… the custom ELResolver extends EL to allow the invocation of bean methods.”

You are right that it introduces complexity in the page – programming of a sort where you would not want this to happen. I was looking for the trick in order to be able to use a generic bean that I do not have the source code for. However, perhaps I would be better of introducing just a wrapper between that bean and my page. Let’s say I found this trick to work and posted it to elicit some reactions from people like yourself. If I am misguided and this so-called trick is really utterly useless, I will happily accept that and move on to other useless stuff. That seems to be my forte.

I am not sure yet whether you have been really clever or are suffering from a twisted mind.
It was an interesting read Lucas, but I’m not sure I understand why you want to work like this. Does this reduce complexity in your applications? Does this increase productivity in your applications?
It also looks like this approach introduces code/complexity in places that are not intended to have such code/complexity in JSF and as such “short circuit” the JSF lifecycle, not?
