Something I'm missing about application processes in 4.1?

Question

So I'm trying to create a new application in 4.1. I'm starting out with just the basic login page and I've created a custom Authorization scheme and login/logout procedures that work fine. On the home page, I'm trying to create a region that allows the user to create a new password. I can't get the process to fire - no completion message, no error message. It's supposed to fire after validations/page submit. Here's what it looks like:
declare
  v_usrid      NUMBER        := :G_USER_ID;
  v_usr        VARCHAR2(40);
  v_hash       VARCHAR2(40);
  v_old        VARCHAR2(40)  := :P1_OLD_PWD;
  v_new        VARCHAR2(40)  := :P1_NEW_PWD;
  v_newc       VARCHAR2(40)  := :P1_CONFIRM_NEW_PWD;
begin
  select ADMIN_USERNAME, PWD_HASH into v_usr, v_hash
    from APEX_ACCESS_CONTROL
   where ID = v_usrid;
  if HASH_PASSWORD(v_usr,v_old) = v_hash then
    --Old password matches hash, change password
    if v_new = v_newc then
      update APEX_ACCESS_CONTROL
         set PWD_HASH = HASH_PASSWORD(v_usr,v_new)
         where ID = v_usrid;
        --:new.updated_by := v_usr;
        --:new.updated_on := sysdate;
    end if;
  end if;
end;It worked fine in the last app under APEX 3.2 - I'm literally copying it across.
Just to see if I could get ANYTHING to fire, I created a second process that sets an application variable with the user's location. I use this for a lot of items in the application. It won't fire either. It's pretty simple:
declare
begin
  :G_KEY_LOC := :P1_KEY_LOC;
end;P1_KEY_LOC gets set (if null) to a value tied to the user's login (:APP_USER) from my authorization table and that is working fine. It seems like if I put it in a PL/SQL process, it just doesn't fire at all. What am I doing wrong?

Answer 1

BEFORE Page submit? Uh, in 3.2 I can have page processes that fire On Submit, After Validations and they work fine. If I try to do exactly the same thing here, they never fire. I use the validations to check the values in the fields. It's only AFTER the validations fire that I want the Page Process to fire, because I want the validations to do their job.
Right now, I have the process set to fire when a button is pushed. That's what I'm confused about. Did they change everything about how page processes fire in 4.1?
