Limitations of upgrading from ERP 2004 to 2005

Question

We are evaluation completing an upgrade from ERP 2004 to 2005. However, we found a limitation in note 879335 regarding upgrading the portal.
We have an Enterprise Portal instance that is separate from the SAP ECC J2EE add-in. The ESS components including XSS run on the J2EE add-in.
According to this note, we cannot upgrade the XSS component on the J2EE add-in because it
is not running on EP. Does this mean we need to undeploy the XSS components and then upgrade the J2EE and then install the XSS component? or Do we need to import the XSS component on EP and then
upgrade?
Why is this a limitation?

Answer 1

I have isolated the issue further. In the following code fragment the event is being fired twice the first time and never again:
          If pVal.FormType = 133 And pVal.EventType = SAPbouiCOM.BoEventTypes.et_FORM_LOAD Then
               '// get the event sending form
               'SBO_Application.MessageBox("Hello world")
               oForm = SBO_Application.Forms.GetFormByTypeAndCount(pVal.FormType, pVal.FormTypeCount)
               oNewItem = oForm.Items.Add("Button1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
               oNewItem.Left = 285
               oNewItem.Top = 382
               oNewItem.Width = 100
               oNewItem.Height = 19
               oNewItem.FromPane = 0
               oNewItem.ToPane = 1
               oButton = oNewItem.Specific
               oButton.Caption = "New Button"
          End If
End Sub
The code is an adaptation of the SDK VB.NET sample ('11.SystemFormManipulation'), which is supplied with the latest version of the SDK installation.
The big question is why is the event being fired twice.
