I have a major problem. I cannot figure out what is the problem with my session. I did use session object in dnn 5.0 and it works. There aren't giving me errors on session object. But when upgraded to 5.4 it causes a problem. The session seems to lost or just not so stable. cos' it sometimes return nothing sometimes it does return the object i stored in session.

Does anyone of you know what is the problem and solution to it? Any response really is appreciated.

Thank You

p/s: sorry that I do not know where to post my question and post in here.

Yes. All the keys are match. This was able to run on 5.0, but it cannot run on 5.4. I am thinking maybe there are some configuration over the server or dotnetnuke. I am not sure what are the things different between 5.0 and 5.4. in 5.4 there isn't anymore html folder in app_code folder; that's the only different I know.

Thank for the reply. Any idea?

Thanks

Yes. It is Null.

These are the example code. I wrote them in vb
Private newfiletype as List(of FileType)

Private sub page_load() .....
....
If Not Page.ispostback then
'Session is remove and reassign...
'but this only happen when the page is first loaded.
'when postback this will not be executed
end if

End Sub

Private sub Add() ... ...handler
Session("ProductCategory.newfiletype") = newfiletype
end sub

Private sub Save ...handlers ..
newfiletype = Session("ProductCategory.newfiletype")
end sub

I think the session is some how late or lost. This is very hard. For what I feel this is like hide and seek. Most of the time, I clicked the session return nothing. from most time of one or two time, it return the object....very strange...it is related to postback maybe ,

Thank You
