Make sure that you have registered a class alias for your ActionScript
representation of the Formasi class. You can do so like this:
package bkn.pojo
{
[RemoteClass[(alias="bkn.pojo.Formasi")]
public class Formasi
{
...
}
}
You also need to make sure you have a reference to the Formasi class in your
ActionScript code so that it is linked into the SWF at compile time. There are
several ways to do this. The usual way is to import it and then declare a
private static variable of the type you want to create a dependency. Another
way would be to ensure you're using it in your code somewhere such as a casting
statement or as a type of a function argument etc...

Subject: Re: [flexcoders] Re: DataGrid with labelfunction + POJO
Hi again.
I have tried to make like you told me before :
import bkn.pojo.Formasi;
public function getInstansiNama(item:Object, column:DataGridColumn):String
{
var myPOJOFormasi:Formasi = Formasi(item);
Alert.show("Instansi : " + myPOJOFormasi.instansi);
return "PPP";
}
The value of the instansi : NULL
Here i send to you the source of the function where i get the Formasi List,
because i use that function in dataProvider of my DataGrid:
public Formasi[] getFormasi( String pTahun )
throws ClassNotFoundException, SQLException
{
Formasi[] myFormasi = null ;
try
{
Configuration cfg = new Configuration ();
cfg.configure();
SessionFactory sessions = cfg.buildSessionFactory();
Session session = sessions.openSession();
Criteria crit = session.createCriteria(Formasi.class);
Integer iTahun = Integer.valueOf(pTahun);
crit.add( Restrictions.eq("tahun", iTahun));
crit.setMaxResults(10);
java.util.List formasis = crit.list();
myFormasi = new Formasi [formasis.size()];
formasis.toArray(myFormasi);
//Here the result never is NULL, always have the correct data
System.out.println("+++ Despues de load: " +
myFormasi[0].getInstansi().getNama());
return myFormasi;
}
catch (Exception ex)
{
System.out.println("Exception " + ex.getMessage());
}
finally
{
return myFormasi;
}
}
Thanks in advance

what happens if you cast item to a FormasiFlex, e.g.
FormasiFlex( item).istansi;
