That's a great question ; Frank;

Earlier this week ,

I posted this
thread<http://forums.oracle.com/forums/message.jspa?messageID=3586332#3586332>at
otn jDev's forum too; but no cookies for me !

As i describe there, to work around this "so many call's" I; early
check if my viewObjects parameter are set and if the value is equal my
current params;

So depending on the target viewObject's parameters; I set or not and
re-execute the viewObject;

Other behavior that I would like to insert here, is how we can
coordnate the execution of onChangeEvent (from any faces component) and
onLoadPage ( or prepareModel ) phase;

if we log this two methods we will have;

on Log window;

Hi there ... from prepareModel (loadPage)
Hi there ... from onChangeEvent
Hi there ... from prepareModel (loadPage)

Do we have some "best pratices" for this ??

Or perhaps i'm missunderestanding something ....

Thanks too;
