I don't understand. Vendor.state and SelectOption.state are both Strings.
I cut down my form to only have state on the form so I can post all the
code. The code pulls the correct data from the database and displays it on
the form but when I save it is gives me the following error.
java.lang.UnsupportedOperationException: Model class
com.myprepress.pages.vendor.profile.VendorEntry2$1 does not support
setObject(Object)
<html>
<form wicket:id="vendorEntryForm2">
<select wicket:id="state">
<option></option>
</select>
<input type="submit" wicket:id="save" value="Save"><br>
</form>
</html>
public class VendorEntry2 extends BasePage {
@SpringBean
VendorDAO vendorDAO;
private long tblId;
private Integer oldVersionNumber;
public VendorEntry2(long id) {
tblId = id;
// get the version number to ensure that the object hasn't been
saved to
// the database by another users
// -1 is a new object
if (id != -1) {
Vendor vendor = null;
try {
vendor = vendorDAO.load(id);
oldVersionNumber = vendor.getVersionNumber();
} catch (DataObjectNotFoundException donfe) {
getSession().error("Object not found");
throw new RestartResponseException(new
ErrorObjectNotFound(new
VendorList()));
}
}
// load the object to be displayed to the screen
// make it LoadableDetachableModel so it is not stored in the
session
// -1 is a new object
IModel vendorModel = new LoadableDetachableModel() {
protected Object load() {
if (tblId == -1) {
return new Vendor();
} else {
return vendorDAO.load(tblId);
}
}
};
// add form
Form form = new Form("vendorEntryForm2", new
CompoundPropertyModel(vendorModel)) {
protected void onSubmit() {
Vendor updatedVendor = (Vendor)
getModelObject();
try {
vendorDAO.save(updatedVendor,
oldVersionNumber);
setResponsePage(VendorList.class);
} catch (DataObjectModifiedException dome) {
// try again");
setResponsePage(new VendorEntryError(
"Data changed by
another user. Please refresh and try again.",
tblId));
}
}
};
add(form); // must add form before adding other components
// add state
ArrayList<SelectOption> states = new ArrayList<SelectOption>();
states.add(new SelectOption("AL", "Alabama"));
states.add(new SelectOption("OH", "Ohio"));
states.add(new SelectOption("NY", "New York"));
ChoiceRenderer choiceRenderer = new ChoiceRenderer("display",
"state");
DropDownChoice stateFC = new DropDownChoice("state",
vendorModel, new
Model(states),
choiceRenderer);
form.add(stateFC);
// add submit button
form.add(new Button("save"));
}
}
