Hello dear Sp 2007 Experts! I have 1 CustomList and 1 Document library. In business logic every document from doc lib is related to specific list item. On editing list item we need the ability to upload document to document library and make relationship betwin uploaded document and current edited list item. Need help, don't know where to start. I have already started with Custom Field Type implementation but, when I adding uploadfield to rendered content of custom field templated it gives me an error when I'm trying to save item with/without selected file to upload. Thank you!

You should find a better answer in the "SharePoint - General Question and Answers and Discussion (pre-SharePoint 2010)" forum. I'll move this thread from "Developing apps for SharePoint" forum to the suggested one.Ricalo
