Hi Frank. I read developer guide but this is detail and if you can help ... thanx in advance.
I put code ... in my bean ... I need to insert row in table and commit. Please if you can answer me what`s wrong?
code:
FacesContext fc = FacesContext.getCurrentInstance();
Application app = fc.getApplication();
//Find corresponding object where variable "bindings" reside
DCBindingContainer binding =
(DCBindingContainer)app.getVariableResolver().resolveVariable(fc,
"bindings");
//Find the data control by name from the binding container
DCDataControl dcCtl =
binding.findDataControl("TMFStudServiceDataControl");
//Retreive application module
TMFStudServiceImpl am =
(TMFStudServiceImpl)dcCtl.getApplicationModule();
ViewObject vo = am.getGetIdStudentAnketaPitanje();
ViewObject studentAnketaOdgovor = am.getStudentAnketaOdgovor();
while (j < my_list.size()) {
t = (Object)lista.get(j);
System.out.println("IdOdgovora: " + t.toString());
vo.setNamedWhereClauseParam("p_id_odgovora", t.toString());
vo.executeQuery();
Row currRow = vo.next();
System.out.println("IdStudentAnketaPitanje: +currRow.getAttribute("IdStudentAnketaPitanje"));
//am.insertStudentAnketaOdgovor();
Row newStudentAnketaOdgovor = studentAnketaOdgovor.createRow();
studentAnketaOdgovor.last();
studentAnketaOdgovor.next();
newStudentAnketaOdgovor.setAttribute("IdStudentAnketaPitanje", 1);
newStudentAnketaOdgovor.setAttribute("IdOdgovor", 2);
studentAnketaOdgovor.insertRow(newStudentAnketaOdgovor);
am.getDBTransaction().commit();
}
