Need equivalent of Oracle Forms Row-Level LOV

Question

I came very close, but I am stuck on the last item.
I am trying to build an update form. I have a select box at the top, and when I select a new value, I want it to change all of the values on the form (for update) to the record associted with the value I chose in the Select Box.
I did this with the Master Detail wizard, although I believe that a "Form with a Report ", would work too. With the Master Detail Wizard, I choose "Edit detail on separate page", which creates the page that I am after, then I just delete the others. I then go to the last page (i.e., edit detail), and change the non-displayed primary key to a "Select List with Redirect" and then associate the desired LOV.
It works pretty nicely one I select a value, and it performs the redirect. However; I can't seem to get the form to pre-populate upon startup.
I tried defaulting the Select List, it does not pull in the detail data, unless I select something with the selct box.

Answer 1

Just three last questions.
1) If I want to call another similar form and have it start on the same item that I currently have selected in the select box, how would I pass that parameter, and how would I receive that parameter? I currently create a link on the first page, and use the following to call the second page:
LinkName
2) Is there an easier way to do what I am trying to do other than using a Master Detail Wizard, or Form with a Report. When I use the wizrd to create a single form, it seems to default to an Insert Form, and is missing the necessary function to do what I like.
3) In my first two forms, a record will always exist before I navigate to it. However; I have another class of form, that may not have a record yet. Do I need to create this form differently, or will the approach I've taken above still work if I need the form to do an insert rather than an update into the associated detail table?
