Ok, but how do you handle generated errors.
If the validate finds an error in an input field, it will display the form
again, without going through any action.
So how can you set the setted variables back again to their states. I
encountered this when I was using a list with values from a database passed
on the parameter a user passed in combination with an input form. 
If the validate encountered an error, I got a no collection found.
I solved this by saving the formbean in the session and if validate
generated errors I retrieved the formbean from the session again in a temp
bean and copied the list values from the previous bean back in the new one.
