File upload (again !!!!)

Question

As someone very new to working with OAF, I need a bit more hand holding to create a new file upload page.
I have created a page with the messageFileUpload item which gives me a file open dialog and I know that I also have to add a submit button but I don't fully understand what code and where I need to process the file. (using fnd_lobs would be fine)
I have looked through the forum but I need the level of the tutorials to get me going
Thanks

I've been trying to get this file upload to work but am still having problems. When I run the code, I get a "oracle.jbo.RowCreateException: JBO-25017: Error while creating a new entity row for FndLobsEO.
and when pressing select "No current row for View (FndLobsVO1)"
In my CO I have the following code:
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
if (!pageContext.isFormSubmission())
am.invokeMethod("createFileUpload", null);
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
if (pageContext.getParameter("Submit") != null)
am.invokeMethod("submit");
In the AM I have:
* Creates a new file
public void createFileUpload()
OAViewObject vo = (OAViewObject)getFndLobsVO1();
// Per the coding standards, this is the proper way to initialize a // VO that is used for both inserts and queries. See View Objects // in Detail in the Developer's Guide for additional information. if (!vo.isPreparedForExecution()) {       vo.executeQuery();     }
Row row = vo.createRow(); vo.insertRow(row);
// Required per OA Framework Model Coding Standard M69
row.setNewRowState(Row.STATUS_INITIALIZED);
} // end createFileUpload()
* Commits the transaction.
public void submit()
getTransaction().commit();
} // end apply()
1) Does there need to be any code that populates the columns or does the control sort that out
2) Once this is actually working, where would I get the ID of the inserted record ?
3) Would the PL\SQL processing code be placed in the AM ?
