Error: Unable to process the case:Unknown type. class BAObjectOutputStream, method: writeObject, parameter: System.Byte

Hello,

Since two days I've trying to see the values of my virtualized master entity in the form without any satysfying effect.

I've created the virtualized entity "INWENTARYZACJA_KABLE", which in Oracle Database has 20 rows. In the modules view in Bizagi Xpress I can see every rows clearly.

In Data Model this entity is related to the Process Entity as a Collection (my Process Entity can have many rows of "INWENTARYZACJA_KABLE").

In the form however I can't see any rows of this Collection.

I've tried to see the rows by adding an expression OnStart to the task, in which the form with this collection is located. Here is the body of this expression:

lista = CEntityManager.GetEntity("INWENTARYZACJA_KABLE").GetEntityList("","","","");

for (count = 0; count < lista.Length; count++)

{

w = Me.addRelation("ProcesDec.DostepneKable");

w.setXPath("ADRES_PUNKTU_POCZAT", lista[count].Attributes["ADRES_PUNKTU_POCZAT"].Value);

w.setXPath("ADRES_PUNKTU_KONC", lista[count].Attributes["ADRES_PUNKTU_KONC"].Value);

w.setXPath("TYP_KABLA", lista[count].Attributes["TYP_KABLA"].Value);

w.setXPath("LICZBA_UDOSTEP_WLOKIEN" , lista[count].Attributes["LICZBA_UDOSTEP_WLOKIEN"].Value);

w.setXPath("ID_KABLA", lista[count].SurrogateKeyValue);

}

But in the Web Application I get such an error message:

Error: Unable to process the case:Unknown type. class BAObjectOutputStream, method: writeObject, parameter: System.Byte

Could you help me? What I'm doing wrong and what I should do to see this 20 rows of my wirtualized entity in the collection in the form?

Thank you very much for any help,

Blessings,

Marta
