ValidateUpdate/All are no longer called

[bergsj]

Hi,

I have a logout form in place for quite a long time. Now all of a sudden this does not work any more. When tracking down the cause, I found out that the embeds ValidateUpdate and ValidateAll on this form are not called.
This form is used to 'logout' the user with the following code in the ValidateUpdate embed (like example 3).

    p_web.SetSessionLoggedIn(0)
    p_web.DeleteSession()
    db.DebugOut('p_web.GetSessionLoggedIn()=' &p_web.GetSessionLoggedIn(),'frmLogout')

The debug is placed to see if this embed is called.

But it doesn't. Also when deleting this form and recreate it again doesn't help.
What am I doing wrong of overseeing here?

[Bruce]

Example 3 has a Logout Form which does I think as you're describing.
When I added a p_web._trace statement in there I see it in Debugview.
So I'm guessing the problem might be in your code, or you need to post an example.

cheers

Just added this debugout:
Just before 'case p_stage' I entered: db.debugout('p_stage=' & p_stage,'frmLogout')

Resulting in this debug output:

[1084] `JeGer2 - frmLogout - p_stage=0
[1084] `JeGer2 - frmLogout - p_stage=16384

No stage is called for updating the form...

[Bruce]

can you duplicate the effect in example 3?

[bergsj]

No that's the pain. I can't. I only goes wrong I my current app.

After more than two years I have same problem as Sjoerd.

My LoginForm does not validate. Simply never reach ValidateUpdate code. I tried to play with debugger but only difference between LoginForm in other application and this loginform is that problematic form never receive value Net:ChangeRecord + NET:WEB:StageValidate.
Why is that it is far to complicated to investigate.

As Sjoerd said, no luck with recreating new one.

Best regards,

Djole

Delete Session could be bad option.

you are doing a Logout in the procedure, and on the WebServer, Security tab you have set it to "Delete Session on Logout".

That combination will not work, because your session is deleted half-way through processing the Login form. So the login form will fail.

Just curious...
If I have set  "Delete Session on Logout".
What code must I use in the logout form to logout?
Thanks

[Bruce]

you can logout fine on a "logout page". What you can't do is log out on the _Login_ form. (If you are deleting the session).

Incidentally you probably should not delete the session on a logout. That is for high-security situations, and comes with some inconveniences (specifically not being able to do it inside the login form.)

Then is it ok to code:

p_web.SetSessionLoggedIn(0)
p_web.DeleteSession()

In de Validate Update of a LogOUT form?

Or just coding

p_web.SetSessionLoggedIn(0)

and having set  "Delete Session on Logout". is enought?

[Bruce]

Then is it ok to code:

p_web.SetSessionLoggedIn(0)
p_web.DeleteSession()

Absolutly - as long as you are not in the middle of doing something which is storing things in session variables. For example you can't do the above on a form, especially a LoginForm because the form sets some variables when it opens, and needs those variables in order to work later. Deleting the session while the form is alive will by definition break the form.

If in doubt just call;

p_web.SetSessionLoggedIn(0)


You do not need to manually delete sessions - they are deleted for you when necessary.
