I created this really simple macro parameter whicn is a dropdownlist that read it's value from a xml file and it appears to be working. The only problem is after save the macro and load it again, the previows saved value won't appear selected.

So, everytime i load the macro to change something i have to remeber to set this parameter again.
Could somebody tell me what I missed?

    Public ReadOnly Property ShowCaption As Boolean Implements umbraco.interfaces.IMacroGuiRendering.ShowCaption
        Get
            Return True
        End Get
    End Property

    Public Property Value As String Implements umbraco.interfaces.IMacroGuiRendering.Value
        Get
            Return Me.SelectedValue
        End Get
        Set(ByVal value As String)
            Me.SelectedValue = value
        End Set
    End Property

#End Region

#Region "Events"

    Private Sub RssChannelPicker_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
        If Me.Items.Count = 0 Then
            Dim helper As New SharedFunctions
            helper.LoadSettings("RSSChannels.config", Me)
        End If
    End Sub

#End Region
