Is it possible to use Form.Observer on a form that has one or more
additional elements added to it after page load? I have a large page
that I am trying to refactor. Currently, there is a separate form for
each element in a Sortable UL. Each form has its own observer for
changes, so the page remains live at all times and stays in synch with
the db. This works up to a point, but it falls down and dies horribly
when there are hundreds of forms on the page. I'd like to change this
so that there is one parent form, with all of the elements in it, but
still be able to add and remove groups of elements from the parent
form. Imagine this sort of construction:
form (with an observer)
fieldset id="element_1"
input
input
input
fieldset id="element_2"
input
input
input
fieldset id="element_3"
input
input
input
...
fieldset id="element_900"
input
input
input
Now imagine that I need to be able to insert new fieldsets within the
form after load, using Element.insert, or remove a fieldset using
Element.remove. According to my naive read of the Form.Observer, it
scans the form for form elements at initiation, and then polls those
elements for changes on a schedule. Would I need to tear down and re-
build this observer after each such modification?
Thanks in advance,
Walter
