@billyrudi , it's a little tricky to even try and help out here because you are not explaining what were yoy trying to do, there is no reference to source code etc.
Are you running the demo or your own app?

 

[billyrudi]

hi, i'm running my own app and the error rise whe i switch quikly from one menu to another withot let that the page ad been loaded.
i think the that error rise in the

Sub Page_ParseEvent(Params As Map)
    Try
    Dim eventName As String = Params.Get("eventname")
    Dim eventParams() As String = Regex.Split(",",Params.Get("eventparams"))
    If SubExists(Me, eventName) Then
        Params.Remove("eventname")
        Params.Remove("eventparams")
        Select Case Params.Size
            Case 0
                CallSub(Me, eventName)
            Case 1
                CallSub2(Me, eventName, Params.Get(eventParams(0)))                  
            Case 2
                If Params.get(eventParams(0)) = "abmistable" Then
                    Dim PassedTables As List = ABM.ProcessTablesFromTargetName(Params.get(eventParams(1)))
                    CallSub2(Me, eventName, PassedTables)
                Else
                    CallSub3(Me, eventName, Params.Get(eventParams(0)), Params.Get(eventParams(1)))
                End If
            Case Else
                ' cannot be called diretly, to many param
                CallSub2(Me, eventName, Params)              
        End Select
    End If
  
      
    Catch
        Log(LastException)
    End Try
End Sub

but this is only an idea. it is hard to give you my code because the project is big and is in production.

@billyrudi , well I guess thats for the masters, thought I could put my 4 weeks know how to use again, lets hope someone will pitch in.

 

[billyrudi]

Erel,
can you help me to solve the problem that occours when a webpage i closed before the server have uploaded all content to a client?
in this situetion the server stop responding to any other requests.
tanks Paolo

 

[Erel]

Have you tested it in release mode?

 

[billyrudi]

yes.
i have tested it.
Alain(alwaysbusy)

write me that "closing the page before it is finished may confuse the jetty server so I will have to see if there is something I can do or if it has to be solved by Erel on the server side.
"

 

[Erel]

When you say that you tested it do you mean that you saw the error message or that it stopped responding?

The error message is expected. It should keep responding. You can test it with the online examples: https://b4x.com:51041/smiley/index.html

 

[billyrudi]

In first post i have reported the log of the server when it go on error and after during a new call from a client.
Erel, this accours often in a centos linux server and with the last release of your b4j.
I use mysql server as database and i connection pool closing all regulary.

 

[Erel]

These logs are in debug mode not in release mode.

 

[alwaysbusy]

I'll be working on a new system to do the reconnect that may have some infuence on this. I will put a small pre-alpha team of donators together to test it out, but more info on this when I got something.
