My testcase:
This code normally works, (.setValue(523) correctly selects the user with f_schueler_id=523 and the name (f_name) is displayed).
However, when extending the DataSource and injecting a criteria value, nothing is displayed:
table.ds.xml
TestDataSource:
Executing the same testcase now doesn't show any value, and the DSRequests/Responses are very strange:
DSRequest:
DSResponse:
There *IS* a row with f_schueler_id=523 and f_mandant=1, so this should fetch the same row as before.
Log:
WHERE '0'='1' ????????????????????????
Nothing is special about the table used:
Using smartGWT 4.1p power ( v9.1p_2014-10-09/PowerEdition Deployment ) with MSSQL 2014.
Code:
public class TestingModule implements EntryPoint {
private MultiComboBoxItem userSelectItem;
@Override
public void onModuleLoad() {
// ////////////////////////////////////////////////////////////////////////////
DynamicForm userForm = new DynamicForm();
userSelectItem = new MultiComboBoxItem();
userSelectItem.setOptionDataSource(DataSource.get("table"));
userSelectItem.setAutoFetchData(true);
userSelectItem.setWidth("100%");
userSelectItem.setLayoutStyle(MultiComboBoxLayoutStyle.FLOW);
userSelectItem.setValueField("f_schueler_id");
userSelectItem.setDisplayField("f_name");
userSelectItem.setTitle("table");
userSelectItem.setAlign(Alignment.LEFT);
userSelectItem.setTitleAlign(Alignment.LEFT);
userSelectItem.setRequired(true);
userSelectItem.setValue(523);
userForm.setFields(userSelectItem);
userForm.setWidth100();
final VStack layout = new VStack(10);
layout.setWidth(500);
layout.setMembers(userForm);
layout.draw();
}
}However, when extending the DataSource and injecting a criteria value, nothing is displayed:
