How to refer to VO data in controller's processFor Request method

Question

Hi
This is my scenario.
On my page, I have a table with a check box against each row.
In the processRequest method of controller, I am able to execute the VO query and display the data in the table.
In processFormRequest, I want to identify which rows have been selected by the user. In other words, I want to read/manipulate the VO rows inside the controller.
I tried importing the voImpl class in the controller, but got compilation error. What is the way to read the VO data into controller's processFormRequest method?
Thanks

Here is an Example Code, code which will identify the rows selected. If it's a multi-selection, then use an array or collection to return the selected rows if controller need to access them.
You can also, find an example of this in OAF Dev guide. Search for "Classic Tables"
public String getSelectedRow() -- This has been coded to use for single row selection.
StringBuffer strRowText = new StringBuffer("");
int fetchedRowCount = getFetchedRowCount();
if (fetchedRowCount > 0)
{  // Save the original range size and range start.
int savedRangeSize = getRangeSize();
int savedRangeStart = getRangeStart();
// Alter the range size and start in this order to prevent any
// accidental row fault-in from the database.
setRangeStart(0);
setRangeSize(fetchedRowCount);
Row[] rows = getAllRowsInRange();
for (int i = 0; i < fetchedRowCount; i++)
if (rows[i] != null && "Y".equals(rows.getAttribute("SelectFlag")))
strRowText.append("customerAccountNum="+rows[i].getAttribute("AccountNumber"));
strRowText.append("#customerPartyName0="+rows[i].getAttribute("PartyName"));
break; //Only one row will be selected. If Multi-Selection, delete this line.
// Restore the range size and start. Do in the following order to
// prevent any accidental row fault-in. Reverse order upon
// restoring to a potentially smaller range size.
setRangeSize(savedRangeSize);
setRangeStart(savedRangeStart);
return strRowText.toString();
