Summary0005558: fix for TJvCsvDataSet add fields from csv
DescriptionWhen the definition of a csv dataset is changed (with field additions), when loading an older version of the csv file you cannot modify the value of the new fields (the component raises an Exception with the message 'GetCsvRowItemData: Column index values are corrupt.').

To fix this message, when loading a csv file new fields must be added to all records. This is already 99% implemented in the current (3.40) version of the component, but it was missing the actual appending of the new fields to a record during parsing. This is done in jvCsvData.pas, in the method

procedure TJvCustomCsvDataSet.InternalOpen()

around line 3770 change

if FUtf8Detected then
  ProcessCsvDataRow(Utf8ToAnsi(CsvLine), Counter)
  ProcessCsvDataRow(string(AnsiString(CsvLine)), Counter);


if FUtf8Detected then
  ProcessCsvDataRow(Utf8ToAnsi(CsvLine+AppendStr), Counter)
  ProcessCsvDataRow(string(AnsiString(CsvLine+AppendStr)), Counter);
TagsNo tags attached.
