I have a drop down choice component, and when the selection changes, I udpate
various form fields by Ajax, in the form as follows:
*public HistoryDropDown(final String id, final Map<K, ?> map, final
Component dateField, final
TrackDetailModel model, final TrackAttribute attribute) {
super(id, map);
final String originalValue = model.getOriginalValue(attribute);
add(new AjaxFormComponentUpdatingBehavior("onchange") {
private static final long serialVersionUID = -1;
@Override
protected void onUpdate(final AjaxRequestTarget target) {
// When
selection changes
final String newValue =
model.getAttributeValue(attribute); // What the
new choice?
if (newValue.equals(originalValue)) {
// If back to original value
dateField.setEnabled(false);
// Disable date field
model.restoreOriginalDateAndUser(attribute);
// Restore original data
} else {
// If changing to new
value
dateField.setEnabled(true);
// Enable date field
model.setDefaultDateAndUser(attribute);
// Effective date = today
}
// User =
current user
target.addComponent(dateField.getParent());
// Re-render fields
}
});
}
*
The updates work fine (the screen re-renders properly), but if I then click
the form's Reset button, nothing happens. I saw some other posts that said I
have to do a form.modelchanged(), but that didn't any effect.
