Sometime I want to do manual editing of values, and I want the actualy edit field to be hidden, allow changes to be made in a text area or by some other means, then use AJAX or some type of DHTML/Javascript to set that value.
In my specific case, I have a document stored in the database. The document is stored by paragraphs and I have an Javascript popup for selecting paragraphs from a Tree. When they make their selection, I want to put a comma delimited string in the database value that has the various paragraph IDs that have been selected. Currently, I have to manually do this through Before Edit Events and such. If I could simply make the edit field hidden, and update it's value using the Javascript popup manually, it would make it MUCH easier.
