Hi,
If `$('eventform').oid` is the *ID* of a form field, then you get the
element via `$($('eventform').oid)`. To set a form field's value, you
don't use `update`, you use `setValue`. So:
$($('eventform').oid).setValue(li.id);
I emphasized *ID* above because `$` looks things up by ID, not by
name. So you need to use the `id` attribute on the field's element,
not `name`. From the property name, I'm guessing that's what you're
doing, but if you're using `name` instead, that's also easy: You'd use
Element#down on the form element with an attribute selector:
var form = $('eventform');
form.down("[name=" + form.oid + "]").setValue(li.id);
