Apex 4.1 Login Page 101 Branching Issue

Question

Branching Issue from P101 based upon P101_USERNAME value entered..Please Help!
I'm having the following code on Page101 main 'login' process. The goal is to go to page 100 if the user is a normal V_USER or go to page 200 if the user is V_ADMIN. For the P101_USERNAME value, I'm determining whether the user or admin variable in my login process. However, I'm NOT branching correctly to the expected page.
The function calls to determine whether V_USER or V_ADMIN work correctly in my tests outside of APEX.
To prove the following, I hard-coded the page no. to either 100 or 200 and both of them direct to the right page, upon login, in such instances. However, when I'm determining the branching path with the below function call, the branching fails and Always goes to Page 100..I'm totally perplexed. Please help.
The thread on the forums was helpful but the user who potentially got his answer didn't show the final example as to how it worked for him.
Re: Apex 4.1 Redirect after login
My login process on P101 main apex login page..

BEGIN
IF v_ret IS NULL THEN
BEGIN
v_user := LTRIM(RTRIM(HTF.ESCAPE_SC(v('P101_USERNAME'))));
--//Tested these calls outside of apex and work as expected perfectly.
          IF (my_pkg.is_user(v_user) = 'Y' AND my_pkg.is_admin(v_user) = 'N') THEN
v_ret := 'V_USER';
ELSIF (my_pkg.is_user(v_user) = 'N' AND my_pkg.is_admin(v_user) = 'Y') THEN

END IF;
EXCEPTION WHEN OTHERS THEN NULL;
END;
END IF;
RETURN (v_ret);
EXCEPTION WHEN OTHERS THEN RETURN v_ret;
END getUserRole;
BEGIN
--//Set page path for user/admin. if not use default page 100

--//Hardcoding works as expected. but the above line getUserRole doesn't compute properly
--//The my_pkg.is_user, my_pkg.is_admin work and return values as expectd.

Answer 1

There is a simpler method to accomplish this.
On your home page (typically page 1) create a branch with the branch point "on load before header"
Set the action to your desired target page.
Create a condition based on your user's role .
Which I see are similar instructions to those suggested in your linked message.
