Sub Menu Items Problem

[Aggie85]

Howdy All!

If a root menu item (top) has submenu items, opening the root item causes a NEW SESSION INSTANCE!!! This also happens in the JQueryDemoIW_V2 y'all supply.

How can I fix this? I need to keep within the same active session.

Thanks in advance!

Hi Aggie85,

We can't confirm it!
Check your code, maybe you have OnClick assigned on that menu item with Ajax = False.

Best Regards.

we noticed that

Intraweb creates a new session if the links are invalid, but thats not our responsability.

Also

We found out that in these cases, Intraweb creates a temporary session, that is destroyed immeadiatelly after the request for a unexistent file is created

And also, that's why we've in our demos the following in ServerController.OnNewSession

procedure TIWServerController.IWServerControllerBaseNewSession(ASession: TIWApplication; var VMainForm: TIWBaseForm);
begin
if GSessions.IsValidSession(ASession) then
ASession.Data := TIWUserSession.Create(ASession);
end;

end;

All of this only happens in IW12

Thanks for the quick answer but I still think this is a bug somewhere.

Just do the following:

1) Compile and run your demo JqueryDemoIW14_V2.
2) Set a break point in the ServerController's OnNewSession event.
3) Click on the Menu item in the accordion panel.
4) Click on any of the root items #2 to #4 to drop down the submenu.

You will see a new session started. This cannot be right or it honestly makes the submenu feature practically useless for most session based apps!

If you client to open Root 1 submenu on your demo, it does NOT cause a new session to open!

Again, this is y'alls UNMODIFIED / RUNNING demo application (no changes by me)!

Thanks,

Ok

Final conclusion:

Both in IW12 and IW14, if we set ServerController.AllowMultipleSessionPerUser = True

It creates new sessions when the link to be served is invalid, any link, any control

In IW12, it creates a temporary session, and we can use not GSessions.IsValidSession to determine that it's a temporary session, and the session is destroyed immeadiatelly after the bad link request is processed.

IW14, doesn't have the concept of temporary sessions anymore, so it creates a normal session that will be only destroyed when it's timeout period is reached.

The follow demos were submitted to our friend Alexandre Machado @ Atozed.

I rest my case!

I will try in my code to have an event set... I was just experimenting when I noticed the new session. That is why I went and ran the unmodified version of y'alls demo. If I can fix it with a valid OnClick event, then great. If not, I will have to come up with a different solution for the short time because I can't be creating new sessions that will eventually time out for what I am trying to use it for.

Thanks for the help and explanation.

Now about the Menu Items

The problem is that when you don't define an image, it's setting itself a link to /blank.gif

Please copy wwwroot/css/blank.gif to wwwroot/blank.gif while you wait for a next release

However we've indications from Atozed that they already fixed this for the next new version.

Funny how things work! I was just getting ready tell tell you how to "fix" the problem as I have been experimenting and found that if a submenu item's image didn't have any value, it caused the problem!!!

Well, like I said before, as long as I know how to fix a problem, I am happy to be able to move on!

Thanks,
