Magritte description for a file on the server's FS ?

Hi, I'd like to describe a field that should point to a file on the server's disk. The precise use-case is that I have a seaside component to displays bibliographies in Pier, and I would like to have it display the contents of a .bib file, which is under SVN or similar version/replication control (so it will be updated sometimes without going through Squeak). Currently I'm using MAFileDescription new kind: MAExternalFileModel; ... but that makes Pier ask for a file to upload, when I'd like to specify a server-specific file path. I was thinking of subclassing MAFileModel but now I suspect that defining MAServerFileChooserComponent is the way... correct ? PS. why does MAFileUploadComponent>>#isMultipart actually mean "no file yet"? -- Damien Pollet type less, do more [ | ] http://typo.cdlm.fasmz.org
