            Description

            As described in ICE-7381, the ExportResource class had to be modified to retain the byte arrays of the files generated by ace:dataExporter. Previously, the Resource object only contained a reference to an input stream, which was was request-scoped. So, in cases when the file download failed at the first try, the data wasn't available after subsequent tries, and the downloaded file had no data. To improve this situation, the ExportResource class will have to be modified to re-invoke the generator to produce a new input stream to serve the file, without having to keep the bytes in memory.
