B4J Question Splitting an empty TextField.Text

    'TextField1.Text is empty - just loaded the layout.
   
    Log("*" & TextField1.Text & "*")
    'Logs zero.
    Log("TextField1.Text.Length = " & TextField1.Text.Length)
   
    TextField1.Text = "some text without a comma"
   
    Dim str() As String = Regex.Split(",", TextField1.Text)
    Dim lst As List = Regex.Split(",", TextField1.Text)

    'Logs 1 instead of zero.
    Log("str length = " & str.Length)
    Log("list size = " & lst.size)
    Log("*" & str(0) & "*")
    Log("*" & lst.Get(0) & "*")

Dim TestCases() As String = Array As String( _
    ",,,"      , _
    ",,"       , _
    ","        , _
    ""         , _
    ",,, ,,,"  , _
    ",, ,,"    , _
    ", ,"      , _
    " ,"       , _
    ", "       , _
    " , "        _
)

For Each S As String In TestCases
    Log("""" & S & """" & TAB & Regex.Split(",", S).Length)
