Hi.
I have a ComboBox with items add from query:
(...)
final ArrayList<NombreConceptoSelectItem<Integer>> nombreConceptos = new ArrayList<NombreConceptoSelectItem<Integer>>();
(...)
if (modelLocator.conceptoList != null) {
for (ConceptoVO concepto : modelLocator.conceptoList) {
nombreConceptos.add(new NombreConceptoSelectItem<Integer>(concepto.getNombre(), concepto.getId()));
}
}
NombreConceptoSelectItem:
public class NombreConceptoSelectItem<T> {
String caption;
T value;
public NombreConceptoSelectItem(String caption, T value) {
super();
this.caption = caption;
this.value = value;
}
public String getCaption() {
return caption;
}
public void setCaption(String caption) {
this.caption = caption;
}
public T getValue() {
return value;
}
public void setValue(T value) {
this.value = value;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((caption == null) ? 0 : caption.hashCode());
result = prime * result + ((value == null) ? 0 : value.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
NombreConceptoSelectItem other = (NombreConceptoSelectItem) obj;
if (caption == null) {
if (other.caption != null)
return false;
} else if (!caption.equals(other.caption))
return false;
if (value == null) {
if (other.value != null)
return false;
} else if (!value.equals(other.value))
return false;
return true;
}
}
I have a table with a column of type ConceptoVO and a form with field for add/change its value.
The form implements com.vaadin.ui.FormFieldFactory:
partidaForm.setFormFieldFactory(new FormFieldFactory() {
(...)
@Override
public Field createField(Item item, Object propertyId, Component uiContext) {
AbstractTextField field;
boolean enabled = true;
if ("numeroFactura".equals(propertyId)) {
(...)
} else if ("concepto".equals(propertyId)) {
ComboBox nombreConcepto = new ComboBox("Concepto");
nombreConcepto.addValidator(new NombreConceptoValidator());
nombreConcepto.setEnabled(enabled);
nombreConcepto.setNullSelectionAllowed(false);
Property.ValueChangeListener listener = new Property.ValueChangeListener() {
public void valueChange(ValueChangeEvent event) {
saveButton.setEnabled(partidaForm.isModified());
discardChanges.setEnabled(partidaForm.isModified());
}
};
nombreConcepto.addListener(listener);
nombreConcepto.setImmediate(true);
for (NombreConceptoSelectItem<?> tc : nombreConceptos) {
nombreConcepto.addItem(tc.getValue());
nombreConcepto.setItemCaption(tc.getValue(), tc.getCaption());
}
nombreConcepto.setItemCaptionMode(ComboBox.ITEM_CAPTION_MODE_EXPLICIT);
nombreConcepto.requestRepaint();
return nombreConcepto;
} else {
field = null;
}
(...)
return field;
}
});
My table has a ValueChangeListaner:
public void onChangePartidaSelected(ValueChangeEvent event) {
// in multiselect mode, a Set of itemIds is returned,
// in singleselect mode the itemId is returned directly
Set<PartidaVO> value = (Set<PartidaVO>) event.getProperty().getValue();
Iterator<PartidaVO> valueIt = value.iterator();
PartidaVO partidaVO = new PartidaVO();
if (valueIt.hasNext()) {
partidaVO = valueIt.next();
}
(...)
addItemInForm(partidaVO);
}
But when I select a item in table the value of comboBox not selected correctly.
I have other view with the same table and form but items in comboBox are “static” and work correctly:
final ArrayList<TipoConceptoSelectItem<?>> tipoConceptos =
new ArrayList<TipoConceptoSelectItem<?>>(
Arrays.asList(
new TipoConceptoSelectItem<Integer>("Ingreso", 1),
new TipoConceptoSelectItem<Integer>("Gasto", 2)));
Any ideas?
Thanks
