[xwiki-users] scripting - attachment combined with object

[I'm hoping that scripting belongs here an not in the dev list] I'm trying to tie an attachment to an object. Say, I want to create several TrackingClass objects on a page. But one of the properties I'd like to be a PDF and link. (Or fake it to look like it) I know the properties of a class are primitives plus a few like DbList etc. The table would have these headings: Tracking Date | Description | PDF Link At the bottom of the page I'd have an Add object form: Tracking Date: Description: Attach PDF: [Add Button] This is like the "Creating a FAQ Application" example, but with an attached file in the same form submit. I'm wondering how one might solve this problem? Thanks, Scott
