Jiwa

Hi There

Am getting the attached error and then Jiwa crashes while I'm trying to send an email via the plugin. The error doesnt come up straight away but it takes sometime trying to send the email and then errors and crashes if I say OK. The code chunk is as below

Code: Select all

Private Sub EmailInvoice(ByRef SalesOrderForm As JiwaSalesUI.SalesOrder.SalesOrderEntryForm, candidateReportsToEmail As JiwaApplication.JiwaCollection(Of JiwaApplication.PrintGroup.SalesOrderReports.SalesOrderReport), Optional ByVal ExportFormatType As CrystalDecisions.Shared.ExportFormatType = CrystalDecisions.Shared.ExportFormatType.PortableDocFormat)      
      Try
'      SalesOrderForm.Save()
        If salesOrderForm.GetAbstractPermission("sales order - email invoices") <> JiwaApplication.Security.UserGroup.AccessLevels.Allow Then
            Throw New System.Exception("You do not have sufficient priveleges to email an invoice.")
        End If

        If salesOrderForm.SalesOrder.SalesOrderReports.Count = 0 Then
            If Microsoft.VisualBasic.Interaction.MsgBox("No sales order reports have been defined." & System.Environment.NewLine & System.Environment.NewLine & "Would you like to set some up now ?", Microsoft.VisualBasic.MsgBoxStyle.YesNo , "No Sales Order Reports Configured") = Microsoft.VisualBasic.MsgBoxResult.Yes Then
                salesOrderForm.PrinterSetup()
            Else
                Throw New JiwaApplication.Exceptions.ClientCancelledException
            End If
        End If

        If candidateReportsToEmail.Count = 0 Then
            Throw New System.Exception("There are no reports that are applicable to this particular invoice.  Are there lines to deliver?")
        End If
        ' load print selection dialog       
      Dim emailReportDialog As JiwaSalesUI.SalesOrder.EmailReport = JiwaApplication.Manager.Instance.DialogFactory.CreateDialog(Of JiwaSalesUI.SalesOrder.EmailReport)(New Object() {candidateReportsToEmail}, SalesOrderForm, "Sales Order Entry")
      emailReportDialog.Visible = False
        emailReportDialog.NameToGiveAttachment = "Your invoice-" & salesOrderForm.SalesOrder.InvoiceNo    '<-  You may want to change this attachment name
        emailReportDialog.EmailTo = GetEmailAddress(salesOrderForm.SalesOrder.Debtor.RecID, "Email Invoice")
      emailReportDialog.CC = GetEmailAddress(salesOrderForm.SalesOrder.Debtor.RecID, "CC Email Invoice")
'      emailReportDialog.BCC = "[email protected]"      
        emailReportDialog.From = Microsoft.VisualBasic.Strings.Chr(34) & Microsoft.VisualBasic.Strings.Replace(JiwaApplication.Manager.Instance.Staff.EmailDisplayName, "@", " ") & Microsoft.VisualBasic.Strings.Chr(34) & " <" & JiwaApplication.Manager.Instance.Staff.EmailAddress & ">"
        emailReportDialog.Subject = "Your invoice - " & salesOrderForm.SalesOrder.OrderNo   '<-  You may want to change the Subject text
        emailReportDialog.SelectedReport = candidateReportsToEmail(1)   '<---   This selects which report to email from the list of CandidateReports passed into the Sub.
         
      emailReportDialog.Message = "Dear customer," & System.Environment.NewLine _
                        & "Please find your invoice attached." & System.Environment.NewLine _
                        & System.Environment.NewLine _
                        & "Sent on Processing Sales Order, " & System.Environment.NewLine _
                        & "The Sales Team"
                        
         If emailReportDialog.ShowDialog(salesOrderForm) = System.Windows.Forms.DialogResult.OK Then
'               salesOrderForm.SalesOrder.Email(emailReportDialog.SelectedReport, emailReportDialog.NameToGiveAttachment, emailReportDialog.From, emailReportDialog.EmailTo, emailReportDialog.RequestReadReceipt, emailReportDialog.Subject, emailReportDialog.CC, emailReportDialog.BCC, emailReportDialog.Message, ExportFormatType)
           End If

         Catch ex As System.Exception
         MessageBox.Show(ex.Message+ex.StackTrace)
      End Try
    End Sub

That code snippet has the part which sends the email commented out - so that's not being executed. This indicates to me it's the call to SalesOrderForm.Save() throwing the exception. If that is the case, then your problem is as the message reports - you've got a network connection issue.

After looking closer at your message, it's coming from the Email object - but that part doing the sending is commented out... so the code you've provided isn't the code which generated the error.

Without having an accurate representation of code causing your error, it's not possible for me to provide an explanation for the error or how to avoid it.

Hi Mike

I had commented out that line due to that issue, I have uncommented it and have attached the entire plugin.

This is what happens, when we press the SEND button on the email popup, Jiwa gets struck, left it even for 15 mins and then we had to End Task from Task Manager, and then we get that error. So the main issue is its getting stuck while sending email. The SMTP server, login etc are correct as we can send via the Email button successfully.

Hi Mike

Can you pls kindly advise on this?

I can't get to your error - I think I get another one first (well, technically two errors - your plugin depends on a custom stored proc not provided, but I worked around that).

I get an error processing a sales order for a debtor which is Cash Only because line 51 of your plugin is invoking the Save() method of the sales order within the event handler for the Processed event. It's failing because the sales order had not been re-read at that point so the optimistic concurrency control prevents the update of the SO_Main table.

I note non Cash-Only debtors follows a different branch in your code - so I'm testing that now - but I suspect it will be a similar issue.

Attached is the plugin with some changes made to prevent the error.

What was happening was Crystal Reports was reporting a broken connection after giving up on reading the data because it was being told to generate the report in the event handler for the ProcessingEnd event - which is whilst there are uncommitted changes to the database, so a blocking scenario was caused.

The first change was to handle the Processed event instead of the ProcessingEnd event - so from this:

Code: Select all

AddHandler salesOrder.ProcessingEnd , AddressOf salesOrder_Processed

To this:

Code: Select all

AddHandler salesOrder.Processed, AddressOf salesOrder_Processed

Because you named your method salesOrder_Processed I think you did intend to handle the Processed event, but ended up choosing the ProcessingEnd event by mistake.

Next was to Read the sales order before trying to email, as emailing causes a save. You had a Read in there for *some* scenarios, but if was wrapped in a condition to only read if the ChangeFlag was set (which would have effectively discarded pending changes and likely not what you want).

So, try the revision attached.

And next time if you do provide a plugin to demonstrate an issue, please make sure if it depends on custom tables or stored procs, that they be provided - or the plugin dependency on them removed.

Ideally we want to be able to import your plugin straight into demo data and be able to repro the issue - the easier you make it for us to help you, the quicker our responses will be!
