> Key: CSV-264
> URL: https://issues.apache.org/jira/browse/CSV-264
> Project: Commons CSV
> Issue Type: Bug
> Components: Parser
> Affects Versions: 1.8
> Reporter: Sagar Tiwari
> Priority: Major
> Time Spent: 3h 40m
> Remaining Estimate: 0h
>
> I'm trying to parse to parse a csv like this:
>
> {{CSVFormat.DEFAULT}}
> {{ .withHeader()}}
> {{ .withAllowDuplicateHeaderNames(false)}}
> {{ .withAllowMissingColumnNames()}}
> {{ .parse(InputStreamReader(FileInputStream(fl)))}}
>
> One would expect this code to throw an error if the following csv is given as
> input:
>
>
> {{"","a",""}}
> {{"1","X","3"}}
> {{"3","Y","4"}}
>
> But it doesn't, and asking for `record.get("")` gives the value from the
> second column. The first column is ignored.
