One discrete value disappears

[Alison Givens]

I have the following problem.
(VB.NET 2003 with CR)

I have a report with a multiple-value discrete value and a rangevalue.
The report shows fine in the viewer, but when I hit the export to pdf
button, it only uses one of two discrete values.

This is the code:
Dim BeginPeriode As String
Dim EindPeriode As String

BeginPeriode = Request.QueryString("BeginPeriode")
EindPeriode = Request.QueryString("EindPeriode")

Dim myReport As New RapportAIRCOStoringen

Dim paramFields As New ParameterFields
Dim paramField As New ParameterField
Dim discreteVal As New ParameterDiscreteValue
Dim rangeVal As New ParameterRangeValue

paramField.ParameterFieldName = "FiliaalKeuze"
discreteVal.Value = "2044"
paramField.CurrentValues.Add(discreteVal)

discreteVal = New ParameterDiscreteValue
discreteVal.Value = "2344"
paramField.CurrentValues.Add(discreteVal)

paramFields.Add(paramField)

paramField = New ParameterField

paramField.ParameterFieldName = "Periode"

rangeVal.StartValue = BeginPeriode
rangeVal.EndValue = EindPeriode
paramField.CurrentValues.Add(rangeVal)

paramFields.Add(paramField)

crViewer.ParameterFieldInfo = paramFields
myReport.SetParameterValue("Periode", rangeVal)
myReport.SetParameterValue("FiliaalKeuze", discreteVal)
crViewer.ReportSource = myReport

As you can see I use myReport.SetParameterValue to feed the pdf.
It goes wrong with the discrete value. It only sees the second value I
entered and not the first.
How can I get this going?
Kind regards,
Alison
