Zip files are ingested in EngageOne Vault using the collections method. While rendering those files via the Perl client, prompted to save them as a zip file that is named "<File Name>.zip". However, while rendering through Java ServiceWeb2 Vault client, it is prompted to download file with "render.do" name.
Some rendering output (i.e. collection mode), while downloading as a file, the ServiceWeb2 doesn't create a file name for it (account + date + file + ...), so the browser will use the servlet name (render.do) as the default file name. This is a known defect in releases prior to EngageOne Vault 7.0M2p0021
ResolutionUPDATED: January 28, 2020
Upgrade to EngageOne Vault 7.0M2p0021 and later releases.
