I am converting a legacy D2W application to Modern style. In the old application the create page for a given entity was frozen and then hand edited. The application implements something similar to ERAttachment and in the frozen edit page there is a plain WOFileUpload button. All the files go into the same directory (unlike with ERAttachment, where the files are stored in a multi-level subdirectory structure).

I want to do as much as possible without custom components (at least no page level components). I can easily do the Create/Edit/List page configuration for the given entity, but I am struggling with the file upload. I don't think I can use ERAttachment, or can I? My data model is Product <-->> Attachment (yes, the name already maches). Attachment has just a to-one relationship to product and a file name attribute (path is "hard coded" via properties file. It is is certainly possible to extend the existing Attachment entity with more fields, but how wold I handle the differing way of storing the attached files? This is a legacy application where I cannot just simply alter the file system layout. And there are already several 1000's of attachments.

No takers? I have been playing with and studying the source of ERAttachment and things (including ERMD2WEditAttachment) but I cannot make sense of these things (yet). This is a legacy application that needs to be brought over to the modern D2W world but the data structures and file names are a given and cannot be changed (and don't fit with what ERAttachment needs)
