Session expired

[ToLong]

Hi,

i have hosted the DocuVieware in an asp.net servercontrol, every time i want to start a customcallback (PostCustomServerAction), the viewer shows me an error:

"GdPicture12.WEB.DocuViewareCore.Requests.CustomActionRequestCtx: session expired."

Can anybody help me?

Here's the code of my servercontrol:

            Dim sb As New System.Text.StringBuilder()
            sb.Append("<script language='javascript'>")
            sb.Append(script)
            sb.Append("</script>")

            ScriptManager.RegisterStartupScript(Me.Page, GetType(Page), "RegisterClientInstanceForUserControl_" + _ClientInstanceName, sb.ToString(), False)
        End If
    End Sub

    Private Sub mcDocuVieware_CustomAction(sender As Object, e As CustomActionEventArgs) Handles mcDocuVieware.CustomAction
        RaiseEvent CustomAction(sender, e)
    End Sub
End Class

Thank you!

Hi,

This means the DocuVieware session timeout has been reached. You can specify a value through the TimeOut property of the control. IE a value of 20 means a timeout of 20 minutes.

Please let us know if you need further information.

With best regards,

Thanks for you're answer - But the error occurs everytime

I'v tested value -1 and 20 without success.

I'm starting the website with visual studio, once it's running, i want start the callback -> Error occurs.

best regards

This is quite strange. Are you on the latest release?

If yes, are you able to reproduce the issue in a standalone application that you can share with our team? Please send it through http://support.orpalis.com

okay i solved the Problem - i had different Versionnumbers of gdpicture in web.config and asp file.

but the Problem is not solved at all

take the following Code, add it to a Project, then add the created Control on a webform and try to post a custom Action with a button on the form

With:
DocuVieware.PostCustomServerAction('DocuVieware1', true, 'test','');

The server-side Event in the Control never gets called - i only get System.NotSupportedException in the Visual Studio Output.

    Protected Overrides Sub CreateChildControls()
        mcDocuVieware.ID = "DocuVieware1"
        mcDocuVieware.Timeout = -1

        mcDocuVieware.Style.Add("width", "100%")
        mcDocuVieware.Style.Add("height", "100%")
