You have to do something like caret-1, and do some logic to detect if the current line contains at least one character, and if it doesn't do a line++, something along those lines.
My suspicion (which I just confirmed) was that the caret isn't actually counted as a character in the textField, therefore when you do getLineIndexOfChar(caret) caret is always 1 number higher than the array getLineIndexOfChar is referencing to do the lookup.
