B4X: 
' Select a new file
Sub buttonOpen_Action
    Dim fc As FileChooser
    fc.Initialize
    fc.InitialDirectory = File.DirApp
    fc.InitialFileName = "ronoteritems.txt"        '<-- exception
    fileNotes = fc.ShowOpen(MainForm)
    Log(fileNotes)
End Sub

Thank You

Works for me. You need to post the stack trace from the logs pane so we can see what the actual exception is. Take a screenshot or right click on the Logs pane to copy to the clipboard.

I can't reproduce that error, it works fine for me although I note that InitialFileName is only displayed in a Save dialog and not an Open dialog.

The error is a MissingMethod error. Make sure you have Java 7 update 6 or later on your system, although if it were an earlier version I wouldn't have thought it would have successfully compiled that code in the first place.

Upgrading to a newer version of Java should solve this error.


The code is already compiled so the compiler doesn't "touch" it.

Upgraded to JDK1.7.0_45 (from _25) and same for JRE.
The file chooser dialog pops up now, but the filename inputfield remains empty, although
B4X: 
fc.InitialFileName = "ronoteritems.txt"
