Attached is a patch to allow Ajax.InPlaceCollectionEditor to load the
collection using AJAX.
It adds a new option, loadOptionsURL, which is the URL used to load the
values over the interweb. It expects the server to return
<option></option> values. If one of them has a selected="selected"
attribute, it will probably be pre-selected. Not tested that though.
Also only tested in FF, however the only actual new code is a line of
Element.update(), so I don't foresee any X-Browser problems.
As usual, development site, can't show the example to the world.
Yet another patch that will never know what CVS is. Enjoy people.
