How to send data to server - form submission
Hi all,I wanted to check with you if my reasoning is ok.
I have my model object, bound to some controls displayed in the page using
PropertyModel.
I also have one ajax event (using a simple AjaxLink).
When the user clicks this ajax link, some components in the page are added
to the ajax target in order to be updated.
And the components linked to my model object resets to their original
values.
This is happening because there is no submission of information from
browser, that's ok.
One possible solution to this is to add a form component, surrounding my
components. And replace the AjaxLink with a AjaxSubmitLink.
That would submit information from the form in the browser, update my model,
and finally render the components updated.
Finally, the question: Is there any other option to do this? Does wicket
have some component to send information via ajax without a form?
Form submission is the regular way to send information from browser to
server, in regular (no ajax) pages.
I understand that AjaxSubmitLink doesn't submit the whole page, only the
form, and that's nice.
But i wonder if there is some alternate way to link properties to
components.
Thanks in advance!
Juan

I don't see why having multiple ways to send information is reinventing the
wheel.
My point was that form submission is a standard for send information. Is the
classic way.
Ajax doesn't require this. You are able to send information on any
javascript event. And maybe someone had implemented that.
I agree is simpler to have only one entry point. And has consistency, seems
robust.
Wicket triggers the same "conceptual" event, form submission. No matter how
this is triggered, regular sumit or ajax.
Finally, I will add the form component and send info using the standard way.
Thanks!

Not really - I'd liken that to reinventing the wheel. Wicket provides
easy support for linking the component and the model through an ajax
event - form submission. But, you could probably write your own JS
that takes advantage of the wicket-ajax stuff and manually sends the
form values as parameters on the ajax request, etc...

The html and the object component hierarchy would be simplier.My question is
why stay attached to the HTML standard (use forms to submit), if AJAX
doesn't need to.
I need this inside a form, and only for one or maybe two text fields.
If I can link the component to the model without a form, I think it might be
better.
Do you agree?

Why do you want an alternate way? Is there some advantage you see?
