"Session Not Found" in Working Preview

[psamuels56]

Hi Everyone-

I'm puzzled by an error I'm getting and I hope you can help. I've used this concept several times before, but, this time, I'm getting an error. I'm sure I'm missing something simple, but, right now, I'm stumped:

In a simple grid that collects "Payments," I set a session variable called "Session.mySessionVariable" in the "on Summary Section Render"... Here's what it looks like:
getTotal2 = e.summaryValues.AmountReceived.Total
Session.myNewSessionVariable = getTotal2
e.javascript = "alert(" + Session.myNewSessionVariable + ");"


The alert works like a charm and gives me the correct total.

In my XBasic code, I have these commands:
Dim PayTotal as n
Dim JobNum3 as n
JobNum3 = e._currentRowDataNew.Job_ID
PayTotal = Session.myNewSessionVariable


In "debug" mode, when I step to the "PayTotal" command, I get this error:
Session.jpg

As I said, I've used this method before without errors, but I'm obviously missing something.

If you have any thoughts, I'd appreciate them.

Phil

Re: "Session Not Found" in XBasic

the session is in the server, therefore in the preview mode when you debug the session variable is not set.
you can simply assign a session variable value and run the test (to see all other things are working well)or publish ,if you want to be safe, to your local webroot and test it before going to production.

Re: "Session Not Found" in XBasic

may be you have a special need, why you need the session variable to send it to the browser?
are you keeping the data for some other use?

Hi Gandhi-

Well, as it turns out, the simple answer is that I was trying out my code in "Working Preview" instead of "Live Preview" (which is what you were implying in the first response) and that's why the session variable wasn't set. Actually, I realized that when after I was done for the night and turned off my computer (that's what I get for working late at night).

FYI, the reason I need a session variable is that I've created a "Payments" Pop-up Grid for my application. After the payments are updated/inserted/deleted, I need to update the Parent Grid with the new "total" of all of the payments. I created a session variable for the "total" (as shown in the first group of code) and then I can easily update the "total received" field (with XBasic) in the Parent Grid/UX.

As always, thank you so much for your help and input. You're terrific.

Re: "Session Not Found" in XBasic

very good, but you can also do the update without depending on session variable and xbasic which means a call to the server.
you could do something like this in the child grid:
var po = {grid.object}.getParentObject();
po.setValue(name,value);
if there is row involved that can be added to the setValue method.

Re: "Session Not Found" in XBasic

Hmm... That makes sense. I'm trying to decide which is "better."

I'll have to think about it. If I do an update to the "parent" grid, the user will have to do another "submit". With the XBasic, the table will get the update when the user submits the child (payments) grid.

It's probably the same no matter which avenue I choose.

Re: "Session Not Found" in XBasic

It's way better to use Gandhi's suggestion than to use a session variable for this purpose. It's really best to limit session variable use to just variables that are initialized at sign-on time and then never changed.

Re: "Session Not Found" in Working Preview

The problem with the "set value" command is that I need the "Summary Total" of a field in the grid, rather than a "row" field. I don't know how to capture that without using the "e.SummaryValues.AmountReceived.Total" command and setting it as a session variable.

Phil perhaps this thread will help, Ghandi was giving some good advice here as well.
