Lukasz Lenart created WW-5731:
---------------------------------
Summary: JasperReport7CsvExporterProvider sets the record
delimiter to the field delimiter
Key: WW-5731
URL: https://issues.apache.org/jira/browse/WW-5731
Project: Struts 2
Issue Type: Bug
Components: Plugin - JasperReports
Reporter: Lukasz Lenart
{{JasperReport7CsvExporterProvider.createExporter}} in
{{struts2-jasperreports7-plugin}} configures the CSV exporter with
{code:java}SimpleCsvExporterConfiguration config = new
SimpleCsvExporterConfiguration();
config.setFieldDelimiter(reportDelimiter);
config.setRecordDelimiter(reportDelimiter);
{code}
so records are separated by the field delimiter ({{,}} by default, or whatever
{{struts.jasperReport7.csv.defaultDelimiter}} /
{{JasperReport7Aware.getCsvDelimiter}} returns) instead of a newline. The
exported CSV comes out as a single line.
The 6.x plugin ({{JasperReportsResult}}) only sets
{{JRCsvExporterParameter.FIELD_DELIMITER}}, so this looks like a copy-paste
slip from WW-5455. Dropping the {{setRecordDelimiter}} call restores
JasperReports' default record delimiter ({{\n}}).
{{JasperReport7ResultTest.testExportToCsv}} does not catch it because it only
asserts that the output contains the report title; an assertion on the line
count would.
Affects every release since 7.1.0.
