Nope.. The higher the number the longer it will take tp expire. Picture this. Each form has a view state. Durring a PPR, the view state is altered for the form your submitting, but not for the other one. When that form is submitted, the page thinks you're using a form from a long time back. Picture someone hitting the back button 20 times and the. Resubmitting a form..
Generally it's considered bad form JSF, especially one involving AJAX, to have multiple forms.
