I have two different selectItems which fetch data from the same datasource, but something is not working:
table.ds.xml
When you press the button, only one of the selectItems is correctly set (the second one, while the first one remains empty), and you get this error:
Using SmartGWT Power (v9.1p_2014-09-06/PowerEdition Deployment (built 2014-09-06)) with MSSQL 2014.
Code:
public void onModuleLoad() {
DynamicForm df1 = new DynamicForm();
final SelectItem field1 = new SelectItem();
field1.setValueField("f_schueler_id");
field1.setDisplayField("f_name");
field1.setAutoFetchData(false);
field1.setOptionDataSource(DataSource.get("table"));
df1.setFields(field1);
DynamicForm df2 = new DynamicForm();
final SelectItem field2 = new SelectItem();
field2.setValueField("f_schueler_id");
field2.setDisplayField("f_name");
field2.setAutoFetchData(false);
field2.setOptionDataSource(DataSource.get("table"));
df2.setItems(field2);
VLayout vlayout = new VLayout();
vlayout.addMember(df1);
vlayout.addMember(df2);
IButton button = new IButton("Click me");
button.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
field1.fetchData(new DSCallback() {
@Override
public void execute(DSResponse dsResponse, Object data,
DSRequest dsRequest) {
if (dsResponse.getData().length >= 1) {
field1.setValue(dsResponse.getData()[0]
.getAttributeAsInt("f_schueler_id"));
}
}
});
field2.fetchData(new DSCallback() {
@Override
public void execute(DSResponse dsResponse, Object data,
DSRequest dsRequest) {
if (dsResponse.getData().length >= 2) {
field2.setValue(dsResponse.getData()[1]
.getAttributeAsInt("f_schueler_id"));
}
}
});
}
});
vlayout.addMember(button);
vlayout.draw();
}Code:
<DataSource ID="table" serverType="sql" tableName="t_schueler"
>
<fields>
<field name="f_schueler_id" type="sequence" primaryKey="true" />
<field name="f_name" type="text" required="true" />
</fields>
