ADF create form problem

Question

Hello forum, I know - I am back again. But I am having all kinds of issues developing this ADF BC create form. Given the following scenario, can somebody please explain how he/she would set out to create the following ADF create form?
You a have a db entity call it table with fields1 through 10. During any create transaction, one of field1 or field2 or field3 must be present together with field4 through 10. That is, field1 can be entered along with fields 4 to 10 or field2 can be entered together with fields 4 to 10 or field3 and fields 4 - 10. Field10 can have four exclusive choices (say a, b, c, d) and should default to d (radio button). Field3 should store the name of an uploaded file. At no time can fields 1, 2 and 3 be entered. It is either one or the other.
Here's how I set out to develop this and have been running into all sorts of problems from Row inconsistency issues to 500 Internal errors. I created an unbound select one Radio component with three choices to display either field1 or field2 or field3 depending upon the radio button selected. I used the switcher facet to hide fields 1 and 2, show field 3 if radio button 3 was selected. So whenever radio button 1 was selected, field1 would be displayed, then fields 2 and 3 will be hidden. Initially, I used regular input components to display fields 1 to 3 and then try to map them back to the database but couldn't figure out how to do this. I then followed John's suggestion to use transient entity attributes. I did this but still couldn't figure out how to access their values so I could set the relevant db columns accordingly.
Because of the way this requirement is, I had to drag and drop field1, 2, and 3 in three different single drag and drop operations, then drag and drop the entire collection with the option to include the submit button, delete fields 1 through 3 in another operation. This created 2 different iterators in the pageDef file. I am not an expert yet on ADF but maybe this might be part of my problems. Trying to use two different iterators to insert into a single table during a single DML operation. But then again both iterators are bound to the same entity. I am not sure anymore.
Is anybody kind enough to take a look at what I have so far? John? Frank? Steve? Anybody? I am trying to make that switch from oracle forms to ADF. This is actually my first ADF form and so far it has been very frustrating. I really need help on this guys!!
Thanks

Thanks for the suggestion Frank! Just so I understand you, the ADF Faces text component that I am adding would be in addition to the radio select one component? Then if you click on radio button 1, enter data in the text field, that action should bind it to field1 and similarly for the other fields when radio button 2 or 3 is clicked? In this case I am assuming that I do not have to display the actual db fields1 - 3 on the form?
This would be fine for fields1 and 2 (though field2 would require one to enter a substantial amount of text - on average a 1000 characters as opposed to field1 that has a maximum length of 40 characters). Field3 however is different because it should be an inputFile component in order to download OS files and store in the database. Thus the ADF Faces text component might not be able to handle this without substantial additional java code.
Thanks again for your suggestions. I really appreciate it!
