Error using SaveCSV

splatt · Mar 9, 2011

I'm trying to write some persistant values to a CSV file:

B4X:

Sub SaveValues
   Dim su As StringUtils
   Dim table As List
   Try
      table.Initialize
      table.AddAll(Array As String("ExtDir",ExtPegDir))
      table.AddAll(Array As String("CatFile",PegSet))
      table.AddAll(Array As String("BGDir",ExtBGDir))
      table.AddAll(Array As String("BGFile",CurrentBG))
      table.AddAll(Array As String("Side",LeftOrRight))
      su.SaveCSV(File.DirRootExternal&"/Android/data/encoded.b4a/files", "encoded.csv", ",", table)
   Catch
      Log("SaveValues - "&LastException.Message)
   End Try
End Sub

I'm getting this error:
SaveValues - java.lang.ClassCastException: java.lang.String

The values I'm adding are these:
ExtDir - /mnt/sdcard/Android/data/encoded.b4a/files/encoded/Alternate Pegs/Numbers
CatFile - Numbers.cat
BGDir - ""
BGFile - wood_grain.gif
Side - Right

Any suggestions as to what may be causing the cast error?

I have rewritten my SaveValues and ReadValues routines using Maps. These work very well.

However, I would still like to try and resolve the cast error above, as I have tried using SaveCSV a few times now and have always had the same problem.

Any advice greatly appreciated.

In order to debug it please comment the Try Catch statements. It will print the stack trace to LogCat when the error happens. Please post the stack trace.

i get the same error, here is the LogCat

The list that needs to be written to a csv file is in a module named FService.

Code:

Dim su As StringUtils 'in future use CSV2 that includes a settings header line(from a list)
su.SaveCSV(DumFolder,DumFile,",",FService.DataSetService) 'adds .csv to make a new file
ToastMessageShow("Data Saved To .csv File", False)

The list should hold arrays of strings. Seems like your list holds arrays of floats.
