Error message

Not yet available

What it means

Thrown in DataHolder.copyToBuffer when a String value is requested from a cursor window but no value is present at that row/column position — a sentinel for a not-yet-populated string value rather than a user-input error.

Solutions

1. Check the value with getString(index) and handle null before copying into the CharArrayBuffer
2. Verify the row and column indices are in bounds and the column holds a string
3. Ensure the DataHolder was fully populated from its cursor before reading
