Validating form components in a refreshing view
Hi there,
I'm new to wicket and have a problem I can't find out for myself.
Maybe some of you can help me out with this.
I have a refreshingview with input fields each row. I can add new rows
on click of a button, but when I submit the form, I want to validate 2
input fields from different rows. Everything I tried so far hasn't
worked out, because I was only able to validate values from one row.
Is it even possible to do something like this?
Greetings
Tobi

Posted by Paul Bors <pb...@knoa.com>.
For example of how you could validate a form given multiple form fields take a look at how EqualInputValidator is implemented.
You would have to keep references to the form fields that are related and return them as an array via IFormValidator. getDependentFormComponents() of your own IFormValidator implementation. Then you can add as many of those you want to your form.
Wicket form processing:
------- ---------- --------- ---------- -------- ------------
| Start | -> | required | -> | convert | -> | validate | -> | push | -> | onSubmit() |
| | | checks | | input | | input | | input | | |
------- ---------- --------- ---------- -------- ------------
| | | |
fail fail fail fail -----------
| | | | | onError() |
- - - - - - - - - - - - - - - - - - - - - - - - - - -> | |
-----------
I recommend reading "Wicket in Action" (http://manning.com/dashorst/) or any other books listed on Wicket's website (http://wicket.apache.org/learn/books/).

Hi Josh,
you're right,
I haven't put any in this example because I am really not sure how I should accomplish this.
If I choose a FormValidator with the FormComponents textOne and textTwo, I can just compare the values of one row.
I will extend my example later.

Re: Validating form components in a refreshing view
Posted by Tobias Knierim <to...@googlemail.com>.
Hi Josh,
I just created a little example of how my application is working:
I want to compare value2 from Entry1 with value1 from Entry2 and so on.
Any ideas?
Form<Values> form = new Form<Values>("form");
add(form);
RefreshingView<Entry> refreshingView = new
RefreshingView<Entry>("list", values) {
@Override
protected Iterator<IModel<Entry>> getItemModels() {
List<Entry> entryList = values.getObject().getEntryList();
ModelIteratorAdapter<Entry> mia = new
ModelIteratorAdapter<Entry>(entryList.iterator()) {
@Override
protected IModel<Entry> model(Entry object) {
return new CompoundPropertyModel<Entry>(object);
}
};
return mia;
}
@Override
protected void populateItem(Item<Entry> item) {
IModel<Entry> model = item.getModel();
item.add(new TextField<String>("textOne", new
PropertyModel<String>(model, "value1")));
item.add(new TextField<String>("textTwo", new
PropertyModel<String>(model, "value2")));
}
};
form.add(refreshingView);

Tobi ;
May be you can paste some code to show how you are constructing the
forms...
I believe if you just add the validators to the components and then submit
the forms, it just works..

Hi ;
Is the whole listview wrapped in 1 form or there is a form for each row?
