Problem set dateformat Exporter

[SopaSeca]

There is a problem with setting the setting of the dateformat of the exporter.
The dateformat is used in the fileBuilder but when you initialise the exporter with the data container the filebuilder is created and the method 'setDateFormat' does not update this filebuilder, thus this dateformat is not used.
ex.

This will not work:
excelExporter = new ExcelExporter(table.getContainerDataSource(), table.getContainerDataSource().getContainerPropertyIds().toArray());
excelExporter.setDateFormat("dd-MM-yyyy");

This works:
excelExporter = new ExcelExporter();
excelExporter.setDateFormat("dd-MM-yyyy");
excelExporter.setContainerToBeExported(table.getContainerDataSource());// here the fileBuilder is created and the dateformat of this builder is set!!!
excelExporter.setVisibleColumns(table.getContainerDataSource().getContainerPropertyIds().toArray());

Kind regards,
Erik
