B4J Question MapRead with custom types issue [sorted]

[Terence Agius]

I posted this issue and since then I have reviewed all pertinent videos and there is no explanation why the following code should not work. I only need to understand why, if anybody can help.

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    
    Type mytype  (a As Int, b As Boolean, c As String)
    Private gmapTest As Map
    
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    'MainForm.RootPane.LoadLayout("Layout1") 'Load the layout file.
    MainForm.Show
    
    Private        temp As mytype
    Private     obj As Object
    Private     map As Map

    map.Initialize
    temp.Initialize
    
    temp.a = 1
    temp.b = False
    temp.c = "Hello"
    map.Put( "key1", temp )
    
    temp.a = 2
    temp.b = True
    temp.c = "World"
    map.Put( "key2", temp )
    
    obj = map.GetValueAt( 0 )
    Private type1 As mytype = obj   
    fx.Msgbox( MainForm, type1, "")
    
    File.WriteMap( File.DirApp, "testmap.txt", map )
    
    'gmapTest.Initialize
    gmapTest = File.ReadMap( File.DirApp, "testmap.txt" )
    obj = gmapTest.GetValueAt( 0 )
    Private type1 As mytype = obj
    fx.Msgbox( MainForm,type1, "")
    

End Sub


'Return true to allow the default exceptions handler to handle the uncaught exception.
Sub Application_Error (Error As Exception, StackTrace As String) As Boolean
    Return True

I already answered your question here: https://www.b4x.com/android/forum/threads/map-bug-or-i-am-missing-something.89821/#post-567897
And it is covered in the video tutorial I referred you to.
And it is also mentioned in File.ReadMap documentation. All values in the map will be strings.

Use B4XSerializator instead.

I understand now. ReadMap returns 2 strings only. Took me a while. I am struggling with casting and wanted to be sure I know what I am doing.
Thanks for the help.
