B4J Question [jTableViewExtended] unexpected behavior in release

[Lahksman]

Getting some strange behavior (dunno if it's my behavior or the tableview).

If i run following code in debug mode, everything works as expected but in release (not obfuscated) i'm getting a NullPointerException.

Sub Row_MouseClicked (EventData As MouseEvent)
    If EventData.ClickCount > 1 Then
        Try
            Log("EventData: " & EventData)
            SQL1 = mDBaseConnector.ConnectToDBase("com.mysql.jdbc.Driver","jdbc:mysql://...")
            Dim cur As ResultSet
            Dim objGame As cGames
            objGame.Initialize
            Dim Row As TableRow = Sender
            Log("Row: " & Row)
            Log("Row index; " & Row.Index)
            Dim Items() As Object = exttvDocknode1Games.Items.Get(Row.Index)
            Log("item 0 :" & Items(0))
...

This gives me the following log in release

EventData: (MouseEvent) MouseEvent [source = TableRow@42f4026e[styleClass=cell indexed-cell table-row-cell]'null', target = Text[text="07/01/2017", x=0.0, y=0.0, alignment=LEFT, origin=BASELINE, boundsType=LOGICAL_VERTICAL_CENTER, font=Font[name=System Regular, family=System, style=Regular, size=15.0], fontSmoothingType=LCD, fill=0xffffffff], eventType = MOUSE_CLICKED, consumed = false, x = 206.0, y = 14.0, z = 0.0, button = PRIMARY, clickCount = 2, pickResult = PickResult [node = Text[text="07/...Sender: null
Row: null

and following log in debug

EventData: (MouseEvent) MouseEvent [source = TableRow@400915ee[styleClass=cell indexed-cell table-row-cell]'null', target = TableColumn$1$1[id=null, styleClass=cell indexed-cell table-cell table-column]'20', eventType = MOUSE_CLICKED, consumed = false, x = 311.0, y = 18.0, z = 0.0, button = PRIMARY, clickCount = 2, pickResult = PickResult [node = TableColumn$1$1[id=null, styleClass=cell indexed-cell table-cell table-column]'20', point = Point3D [x = 39.0, y = 18.0, z = 0.0], distance = 1974.2548...Sender: flm.b4j.tableviewextended.RowWrapper@541e767a

Comment out the Try / Catch and post the full error message.

It doesn't look like the best design to connect to the database from the click event.

The database connector was only in there for testing purpose.

Removed the try / catch (did it before already) but still the same result. This in in the log (release mode).

[Informatix]

"Dim Row As TableRow = Sender" should be the first line in your code. What's the result once moved?
Sender should not be read after calls to functions because they may trigger events or perform a Callsub and thus Sender could not have the expected value.

Thx @Informatix that was it.
Sound perfectly logical once you know it.
