Why is this property empty when I added child controls and can seethem?

[shapper]

Hello,

I have a control with the following property:

Private _Sections As New List(Of FormSection)
Public Property Sections() As List(Of FormSection)
Get
If _Sections Is Nothing Then
_Sections = New List(Of FormSection)
End If
Return _Sections
End Get
Set(ByVal value As List(Of FormSection))
_Sections = value
End Set
End Property

FormSection is another custom control. My control inherits from
CompositeContro l and I implement it as follows:

Protected Overrides Sub CreateChildCont rols()
For Each section As FormSection In Me.Sections
MyBase.Controls .Add(section)
Next
MyBase.CreateCh ildControls()
End Sub

Finally I need to run a method from a child control in each section
when a Bubble event is caught:

Protected Overrides Function OnBubbleEvent(B yVal source As Object,
ByVal e As EventArgs) As Boolean

If TypeOf e Is CommandEventArg s Then

For Each section In Me.Sections
For Each field In section.Fields
If Not field.Validate Then

' Stop bubbling for EventArgs
Return True

End If
Next field
Next section
OnCommand(e)

End If

' Let bubbling run for non CommandEventArg s
Return False

End Function

The problem is that Me.Sections has no section in it so the loop does
not run.

But the sections are there! I added them and when I run the page I see
all them.

What am I doing wrong?

Thanks,

Miguel
