property converting model

[Tom Eugelink]

I've got a form bound to a CompoundPropertyModel. One of the properties contains a XML document. In order to edit that property, I've added a TextArea to the form (with the CodeMirror javascript XML editor bound to it), but I need to convert the XML document property to string and back again. I've implemented this by creating an anonymous model, like this:

             lForm.add(new TextArea<>("services", new IModel<String>()
             {
                 @Override
                 public void detach()
                 {
                 }

                 @Override
                 public String getObject()
                 {
                     return JAXBUtil.extractAndSerializeServicesElement(lLicenseJAXB);
                 }

                 @Override
                 public void setObject(String s)
                 {
                     try
                     {
                         JAXBUtil.parseAndSpliceServicesElement(lLicenseJAXB, s);
                     }
                     catch (Exception e)
                     {
                         lErrorOccurredAtomicBoolean.set(true);
                         slf4j.error("Error during submit", e);
                         error(e.getLocalizedMessage());
                     }
                 }
             }).setOutputMarkupId(true).setMarkupId("codemirror"));

There are a few question I have:
1. Is this the right way to add such a conversion?
2. Will this model be persisted to the session as well? I of course do not want that, it just needs to convert.
3. If there is an exception in setObject, I use an AtomicBoolean to register that, so that the Form.onSubmit knows that something is amiss. Otherwise I get a big fat exception on the screen or the ssubmit just continues. Is there a better way?
4. If there is an error, I would like getObject to return the value that was submitted by the form, so that the user can correct his mistake. Now it always returns the value before the edit. How to do that?

Hi,

Use a custom IConverter instead - override TextArea#getConverter(Class) method.
Conversion of data is part of form submit process and if it fails with
org.apache.wicket.util.convert.ConversionException then the model of
that component is not updated and Form#onError() will be called. Point
4) below will be automatically handled for you by Wicket.

The converter correctly converts, but if there is an error in the converter, I'm getting a exception dump on screen.

Root cause:

org.xml.sax.SAXParseException; lineNumber: 4; columnNumber: 3; The element type "notificationx" must be terminated by the matching end-tag "</notificationx>".

"... and if it fails with

try/catch your code and wrap the original exception in
ConversionException and rethrow

My understanding of this class must be faulty. When Wicket calls my
onSelectionChanged(), the argument is the display string, not the id
value. For example, I'm expecting a milepost value like "123.456", but
instead I get "End (123.456)" (the display value). Here's the code. can
anyone see what I'm doing wrong?

private RadioChoice<String> createMilepostChoice(final String id, final
TrackModel track) {

        final Milepost     startMP = track.getStartMP();
        final Milepost     endMP   = track.getEndMP  ();
        final List<String> choices = Arrays.asList(new
String[]{format(START, startMP), format(END, endMP), OTHER});
        final ChoiceRenderer<String> renderer = new
ChoiceRenderer<String>() {
                private static final long serialVersionUID = 1L;
        @Override public Object getDisplayValue(final String model) {
            return model;
        }
        @Override public String getIdValue(final String model, final int
index) {
                String value;
                switch (index) {
                        case 0:
                                value = startMP.toString();
                                break;
                        case 1 :
                                value = endMP.toString();
                                break;
                        default :
                                value = "";
                }
                return value;
        }
        };
        final RadioChoice<String> choice = new RadioChoice<String>(id,
choices, renderer) {
                private static final long serialVersionUID = 1L;
                @Override protected void onSelectionChanged(final Object
new selection) {
                        final String selection = (String)newSelection;
                        if (track == primaryTrack) {
                                primaryMpChoice = selection;
                        } else {
                                secondaryMpChoice = selection;
                        }
                }
                @Override protected boolean
wantOnSelectionChangedNotifications() {
                        return true;
                }
        };
        return choice;
}

Your RadioChoice is working on string choices so it will hand you the
selected string.

I'd suggest to let your RadioChoice work with ints or preferably
directly on the Milepost objects:

     final RadioChoice<Milepost> choice = new RadioChoice<Milepost>(...);

Ok, I tried changing it to RadioChoice<MilepostModel> (code below).
However, the onSelectionChanged() method STILL gets a String argument, as
verified by the printf() output "New selection is a class
java.lang.String: End (538.200)." But following that output, an exception
is now thrown. I REALLY don't understand what's going on here. I've
studied the Javadocs for RadioChoice, but they seem awfully sketchy, and
don't shed any light on this.

Oops. Got it figured out. The page class was trying to store the choice in
a String variable instead of a MilepostModel variable. All is well now.
Thanks!
