Re: Form and PageParameters
Is it a must that you use PageParameters for RequestPage?
Do you need an access to it also from a URL (after mounting it in your
Application).
I think that a nicer way is to add a constructor that accepts the values.
Even better, I would have created a POJO model.
Use a CompoundPropertyModel with the form, and pass this object to the
RequestPage.

Hi,
I have created a RequestPage html page containing a form (= search
criteria) and a list (= Data View where the result set of data retrieved in
a DB according to search criteria is displayed). When the user clicks on
the
search criteria button of this page, the request is redirected to the
RequestPage where we extract the search criteria values and pass them to
the
service in charge to retrieve the data. In the java class accompagning this
page, I have overrided the onSubmit method of the submit button to pass
the value of the form fields
public RequestPage(final PageParameters parameters) {
...
Form form = new Form(searchCriteriaRequest);
// Add fields
fRequestId = new TextField(fRequestId, new Model());
fFileName = new TextField(fFileName, new Model());
form.add(fRequestId);
form.add(fFileName);
// Add buttons
button = new Button(button) {
@Override
public void onSubmit() {
parameters.add(requestId, fRequestId.getValue());
parameters.add(fileName, fFileName.getValue());
setResponsePage(RequestPage.class, parameters);
}
};
form.add(button);
add(form);
In the constructor of this RequestPage, I call a populate method with
PageParameters
// Populate list with search criteria values
populateList(parameters.getKey(requestId),
parameters.getKey(fileName));
Questions :
1) Is it the good way to handle PageParameters and Form in Wicket ? If this
is not the case, can someone point me to a good example ?
2) The fields filled in the previous post of my page are not removed when I
repost a new request on my page. How can I reset these fields from the
request of the new post ?

Re: Form and PageParameters
Thx for the reply.
You are right, it is not a must to use PageParameters but as this is my
first Wicket project, I have started to work with simple things.
In the meantime, I have had a look to the formInput example where a
CompoundPropertyModel is used. I have adapted the Form to work with it.
My question is now :
When I call the first time my page, the url is : http://localhost/request.
Wicket receives this request and the constructor RequestPage(PageParameter
pageParameter) is called. Next, after filling my form in the page and
clicking on the onSubmit button, the request is submitted to the same page.
How can I retrieve the values of the CompoundPropertyModel from my form in
this case ? Do I have to do something particular in the
setResponsePage(RequestPage.Class) to pass the compoundPropertyModel ? Do I
need to create two different constructors : one for PageParameters and the
other to handle CompoundPropertyModel ?

Re: Form and PageParameters
you can call YourForm.this.getModelObject() in your forms onSubmit or
the buttons onSubmit method.
that would return the model object bound to your CompoundPropertyModel
and you model object would have all the updated values

Re: Form and PageParameters
back to my original question, do you actually need this page to have a
constructor with PageParameters?
hint - if you want a user to get it with nice URL, then yes.
You can call one constructor to the other (sometimes tricky in situation
like yours), or you can have an init() method that does everything and call
it from each constructor.
everything

Many thanks for your help.
With the modifications you propose, everything works fine
Here is what I changed in the onSubmit method of the button
public void onSubmit() {
setResponsePage(new RequestPage((RequestModel)
this.getForm().getModelObject()));
}
Question : Do I have need to duplicate the code between the two
constructors
? I mean Do I need to have in double ?
final FeedbackPanel feedback = new FeedbackPanel(feedback);
add(feedback);
RequestForm requestForm = new RequestForm(requestForm);
add(requestForm);

You can have two constructors in your page.
If you work 'internally' then you can use the one that accepts a pojo. If
you work with URL, then the one that accepts PageParameters will be used.
the setResponsePage can accept a Page and not only a class, so what you
can
do is create your page: new RequestPage(myPojoModelObject), and then put
it
in the setResponsePage parameter.
IllegalArgumentException: A child with id 'requestList' already
means that you added it already to your page. AFAICS you don't go to a
new
page in the button submit so you add the list over and over again.
if you want to update a list, use a dynamic model for the content and
update
it.
