You're using the wrong model object, this should be:
final Integer newSubdivision = dropdown.getModelObject();
or:
final Integer newSubdivision = PointLocationPanel.this.subdivision

I have a drop down choice in a FormComponentPanel, and & need to update
other parts of the panel when the user changes the selected value in the
drop down. My panel class is defined as:
PointLocationPanel extends FormComponentPanel<PointLocation>
Its constructor begins like this:
public PointLocationPanel(final String id, final IModel<PointLocation>
model,
final String boxTitle, final MapURL mapURL) {
super(id, model);
setType(PointLocation.class);
...
This is the method where I create the drop down.
private SubdivisionDropDown createSubdivisionDropdown() {
final SubdivisionDropDown dropdown = new SubdivisionDropDown
(SUBDIVISION, new PropertyModel<Integer>(this, SUBDIVISION
));
dropdown.add(new AjaxFormComponentUpdatingBehavior(ONCHANGE) {
private static final long serialVersionUID =
-1285532100134482101L;
/*
* When the user picks a different subdivision, update the
segment
* drop down list to show segments in the newly chosen
subdivision.
*/
@Override protected void onUpdate(final AjaxRequestTarget
target) {
final Integer newSubdivision =
getModelObject().getSubdivision();
smrDropdown.update(newSubdivision);
target.addComponent(smrDropdown);
}
});
return dropdown;
}
However, when the onUpdate() method is called & I call
getModelObject.getSubdivision(), it returns the old value, not the newly
selected one. Can anyone see what I'm doing wrong?
