Session Variable no longer found

[RhinoSmith]

Hi-
I'm moving along with my first A5 app, following Steve Workings videos on log-in and session variables. So I have it working, the user logs in and I have a top where the company name and user fullname is displayed as well as a log out link. So all this works and I'm off to start on the first filtered component but come back to test it by logging and now it will not "see" my session variables and produces an error. My intermediate process code is below.

<%a5

dim session.CompanyID as N=0 'set to zero so there cannot be a company primary key with this value.
dim session.SubCompanyID as N=0 'also set to zero
dim session.IsLogixLink as L=.f. 'if the user is from LogixLink, show all data.
dim session.IsLicenseOwner as L=.f. 'if the user does not own the software, make sure they only see their data
dim session.CompanyName as C="" 'to display the company name.
dim session.FullName as C="" 'to display the user's name.
dim session.User as C=""
'Get the Company ID of the current user.
dim GetCurrentUser as C

GetCurrentUser=a5ws_getcurrentuser()
if GetCurrentUser<>"" 'This should never happen at this point.
session.user=a5ws_getcurrentuser()
dim args as sql::Arguments
args.Set("Username",GetCurrentUser)

'Get the Company ID for use throughout program to display proper inventory.
session.CompanyID=sql_lookup("::name::LogixDBLink","LicenseOwners","UserName=:UserName","LicenseOwners_PK",args)

'Get the name of the company for display purposes.
session.CompanyName=sql_lookup("::name::LogixDBLink","LicenseOwners","UserName=:UserName","CompanyName",args)

'Get the full name of the user for display purposes.
session.FullName=sql_lookup("::name::LogixDBLink","LicenseOwners","UserName=:UserName","FullName",args)


end if
response.redirect("Index.a5w")
%>

The code in my "page top" looks like this:
<%a5
If a5ws_getcurrentuser() <> ""
?"Company Name: "+session.CompanyName+" User: "+session.FullName+" <a href=\"Logout.a5w\">(Logout)</a>"
end if
%>

The error that shows up if I hit the "back" button on the browser is:
Script Error
Error:Script:PageTop.a5w line:44
?"Company name is :"+session.CompanyName+"<a href=\"Logout.a5w\">(Logout)</a>"
Property not found
session.CompanyName subelement not found

This is on my developement laptop obviously. Any ideas where I start to track this down. As I said, it worked and I don't think I did anything else to make it stop working. I moved on to creating a simple grid based on a session id. That did not work and that made me go back and look at the log in.

Thanks

Re: Session Variable no longer found.

Probably your session timed out while you were building the grid. Default is 15 minutes unless you change it. If on laptop, see Web > Application Server and then the Sessions tab to increase it. But also, having the session time out should never be allowed to cause a problem like this. Your code should regenerate the session variable if needed.

The code below can cause a problem because a user being logged in does not mean the session has or has not timed out. Said differently, a5ws_getcurrentuser() can return a value (meaning someone is logged in) but the session may have already timed out.

If a5ws_getcurrentuser() <> ""
?"Company Name: "+session.CompanyName+" User: "+session.FullName+" <a href=\"Logout.a5w\">(Logout)</a>"
end if

Re: Session Variable no longer found.

Thanks Steve,
The session timeout is set to 45 minutes and I have recreated the same problem with "test" pages and have been working on it for two days now trying to track it down. The really nasty thing is that it worked for a day just fine. How do you debug something that works and then suddenly doesn't? It has to be some change but I have recreated with clean slate pages and the same problem occurs. I can load the page fine without session variables but when you try to load and use the variables, it doesn't work.

Re: Session Variable no longer found.

Are you deleting or republishing anything out of the webroot while your session is active? What browser and version are you working with? Does the same problem happen in another browser? Are you accepting cookies?

Re: Session Variable no longer found.

Jeremy-
I'm use IE8 and I have tried it in Google Chrome with the same result. Both browsers return with "session.CompanyName subelement not found". I have gone so far as to clear all publishing history and then re-published everything in the project. I can eliminate the variables and put something like the current user and it willl load fine and display that along with the logout page. I have added, removed, attempted to give the variable a hard coded value, whatever to see if it would load and it won't. As I said before, it worked initially just fine and I moved on to something else so I'm at a loss.

Re: Session Variable no longer found.

When you first login does it set the session variable and show it on the page? Once you have done that and you refresh the screen what happens? Do you have any script that you have added since you started that is running and might be clearing any of your session variables?

[jthornton]

Re: Session Variable no longer found.

Try dropping the... If a5ws_getcurrentuser() <> "" .. part of the script on your page top.

Try this to see if it holds.

<%a5
? "Company Name: "+ session.CompanyName +" User: "+ session.FullName + %> then add your logout html link here.

Let me know if that works.

Re: Session Variable no longer found.

Jeremy-
No, it does not set the session variable. As soon as it goes to my processing page, it returns the error. I have not added anything else to it. Right now, I just return to the index page. Later on, I'll redirect to a page based on the user. For now though, it just appears that it will not "see" my variables. As I said, it was working and I did not change anything after it began working that I know of.

Re: Session Variable no longer found.

I'm still not getting this to work. I believe it is some lack of understanding regarding the session time. I have now spent two days on it and really need to move along. To make sure other things worked I created some test pages and hardcoded the "current user" value. My lookup's worked fine and the session variables were set properly and were read correctly on a page redirect including a grid set to filter on a session variable. All that works unless you actually 'log' a person in. Then the variable cannot be found according to the error script on the page. The AS session was orignally set to to 45 minutes. I have tried resetting it to 1 minute, logging out and logging back in. That does not work.
So, do I need to "close" a session on logout? If so, I tried "session.reset()". That did not work.
I have tried changing the security settings on my pages and compenents and that did not make a difference. I currently have them set for "allways allow" for developement purposes but did change them to "login required" to see if that helped and it did not.
Not that I have much wit but I'm at it's end. If anyone can point me in a direction I would apprecieate it.

Re: Session Variable no longer found

I suggest create a short video showing all of the details, code and operation where it fails. Seeing how it works/fails will help. Or if that fails, I offer to remote into your application and debug it. It is likely something simple.

[RhinoSmith]

Re: Session Variable no longer found

Well after a couple more hours here is what it LOOKs like. It looks like when you log in, the security re-direct never re-directs. No matter what page I put into the redirect after login, the page it comes back to is the index page (login). So it never runs my code in the intermediate page. I have enabled security and published the security files (multiple times). Have you ever seen that type of problem before?

Thanks

Re: Session Variable no longer found

It all depends on how you prorammed it, why a video will help. Also, it might skip your intermediate page if you initially target a specific page other than your home page. For instance, if your URL tried to open a secure page, and it kicks you back to Login, then you login - it will go immediately to the originally page targeted in the URL, and will skip any redirection to your intermedate page. Easy to spot if you look at the URL when it hits the Login page, it will have an np=xyz in the URL.

Re: Session Variable no longer found

This is from the Index page where I'm starting with my login component. I've only added the "top page" lines into this.

Re: Session Variable no longer found

This is the 'top page'. There are several lines which are commented out as I'm testing. It will show up fine with just the 'log out' line.

Re: Session Variable no longer found

Hi

I was under the impression that session variables could only be c type, not n or logical ?
