Error since last commits regarding gb.web.gui - WebContainer DeleteChildren

Description
-----------

Hello,

Just after the commit b5ddc041a8169ef0ebc6fd2fd0ef8ffcddf77fec, my application fail now with this error

    Erreur: Null object   Where: [gb.web.gui].WebContainer._CancelChildrenRefresh.233

I think this commit introduced the issue:  Fix WebScrollView and WebContainer 'DeleteChildren()' method.


Function related to the error:

Public Sub WebBtnBienImmo_Click()

  ' Bouton Tab Biens Immobiliers

  If ModVar.CurrentPanel <> "BIENIMMO" Then 

    ModFunction.Creation_Liste_Annee()

    ModVar.CurrentPanel = "BIENIMMO"

    WebContainerTab.DeleteChildren()

    $NewWebBienImmo = New WebformBienImmo(WebContainerTab) As "BienImmoEvent"
    $NewWebBienImmo.Expand = True

    Object.Attach($NewWebBienImmo, WebformMain, "BienImmoEvent")

    ModLogs.EcrireLogs("WebButtonBienImmo_Click() - Bien Immobilier)")

  End If

Catch
  ModLogs.EcrireLogs("Erreur dans WebBtnBienImmo_Click() - Erreur: " & Error.Text & "   " & "Where: " & Error.Where)

End

Olivier
