Error using a binding to get current row data

Question

Hi, from a previous post ( Calling a stored procedure ) that has been answered i have reached to this point and cant get go on:
i have a method declared on appmoduleimpl that calls to a procedure stored in the database and passes two parameters (one string, and one int)to the stored procedure.I drag and drop the method from the data control pallete to my jspx page.
the problem is that i want to get the value of two rows from the current record and set them as values from the parameters.
My Binding:
${bindings.Module3EmpIterator.currentRow.empno}
${bindings.Module3EmpIterator.currentRow.ename}
Note: Module3Emp its the name of my view
when i use this binding i get this error code
JBO-29000: javax.servlet.jsp.el.ELException: Unable to find a value for "ename" in object of class "oracle.jbo.server.ViewRowImpl" using operator "."
javax.servlet.jsp.el.ELException: Unable to find a value for "ename" in object of class "oracle.jbo.server.ViewRowImpl" using operator "."

Thanks.

Here i store a pl/sql code in a method (At AppModuleImpl Level)
public void callProc1 (String ename,
int empno)
PreparedStatement plsqlBlock = null;
// String statement = "BEGIN p_proc1(:1,:2); END;";
String statement = "BEGIN INSERT INTO p_proc (ID, dato, numero) VALUES (s_proc.NEXTVAL, :1, :2); END;";
plsqlBlock = getDBTransaction().createPreparedStatement(statement,0);
try
plsqlBlock.setString(1,ename);
plsqlBlock.setInt(2,empno);
plsqlBlock.execute();
catch (SQLException sqlException)
throw new SQLStmtException(CSMessageBundle.class,
CSMessageBundle.EXC_SQL_EXECUTE_COMMAND,
statement,
sqlException);
finally
try
plsqlBlock.close();
catch (SQLException e)
// We don't really care if this fails, so just print to the console
e.printStackTrace();
now i expose the method and set the variables in the page definition.
<methodAction id="callProc1"
InstanceName="Module3AppModuleDataControl.dataProvider"
DataControl="Module3AppModuleDataControl"
MethodName="callProc1" RequiresUpdateModel="true" Action="999"
IsViewObjectMethod="false">
<NamedData NDName="ename"
NDValue="${bindings.Module3EmpIterator.currentRow.ename}"
NDType="java.lang.String"/>
<NamedData NDName="empno"
NDValue="${bindings.Module3EmpIterator.currentRow.empno}"
NDType="int"/>
(that does it automatically when i drag and drop the method to the jspx page).
This is the code in the command button inside the jspx page
<af:commandButton actionListener="#{bindings.callProc1.execute}"
text="callProc1"
disabled="#{!bindings.callProc1.enabled}"/>
When i click the button, the method should insert the selected column on a new table that i created But it doesn't. How i can do it, or how i can see the output of those values (bindings.Module3EmpIterator.currentRow.empno... etc.)
Note: when i hardcode the values and put Hello instead of bindings.Module3EmpIterator.currentRow.empno it inserts into the table and works everything fine.
