Android Question Types can't be saved in maps?

Private Sub Button1_Click
    Dim mContainer As Map
    mContainer.Initialize
   
    GetDataType = CreateDataType
    GetDataType.Map1.Put("Index0", "Value0")
    GetDataType.Map2.Put("Index0b", "Value0b")
    GetDataType.List1.Add("List0")
    GetDataType.List2.Add("List0b")

    mContainer.Put("First Data Type", GetDataType)
   
    '-----------------------------------------------

    GetDataType = CreateDataType
    GetDataType.Map1.Put("Index1", "Value1")
    GetDataType.Map2.Put("Index1b", "Value1b")
    GetDataType.List1.Add("List1")
    GetDataType.List2.Add("List1b")
    mContainer.Put("Second Data Type", GetDataType)

    '------------------------------------------------
   
    'Read the container
    Log(mContainer.Get("First Data Type").As(DataType).Map1)     'Log: (MyMap) {Index0=Value0}
    Log(mContainer.Get("Second Data Type").As(DataType).Map1)    'Log: (MyMap) {Index1=Value1}

End Sub

Public Sub CreateDataType As DataType
    Dim t1 As DataType
    t1.Initialize
    t1.Map1.Initialize
    t1.List1.Initialize
    t1.Map2.Initialize
    t1.List2.Initialize
    Return t1
