in my project, i have a report ( report1.rdlc)  a standard straframe form  who contain a reportviewer and  a bindingsource named  

BusinessBindingSource1titres

a made the same code like the example SampleCRMApplication

look

Private Sub cmdReport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdReport.Click

If Me.TitresBO1.Count > 0 Then

Using loForm As New Form1()

'-- Retrieve the customer record

loForm.BusinessBindingSource1titres.BusinessObject.FillByPrimaryKey(Me.TitresBO1.identifiant)

'-- Show the form

'-- Close the form

End Using

Else

MicroFour.StrataFrame.Messaging.MessageForm.ShowMessage("You must first select a customer.")

End If

End Sub

I don"t know why, but when i execute this code

an error is on the line 

loForm.BusinessBindingSource1titres.BusinessObject.FillByPrimaryKey(Me.TitresBO1.identifiant)
the error is

the NullReferenceException was not managed by user code.

I dont know whu because i made the same code than the example.

Have I forget something ??

Have you an idee .

Thank's

Best regard
