Re: T5 Newbie : populate the value of a form in a bean
In my case I think I was running in confusion, the MyObject was already
initialized from a previous page and injected in the page that hold the
form.
Thus initialising it from onPrepareFromForm or setupRender is useless in
this particular case.
Things are working fine now, I really don't see what was wrong before as
I can't see what's better now ...
Newbie bad time. Josh send me good vibes ;-)
I'm going to produce a little wiki tutorial on Basic Crud this weekend
because that really miss me.
Thanks for your help and your explainations.
Howard Lewis Ship a écrit :
Generally, what you want to do is replace setupRender() with
onPrepareFromForm().
void onPrepareFromForm()
{
if (_myObject == null) _myObject = new MyObject();
}
"Prepare" means the prepare event, fired from your Form component.
Prepare event is triggered when the form starts to render AND when it
starts to process a submission. Instantiating and object is exactly
what prepare is intended for.
Tapestry will supply an id of "form" for the component. If
you have multiple forms, they may end up being "form", "form_0",
"form_1". I tend to give an explicit id.
You test page is a little different, in that it displays the contents
of the myObject property as well, so your setupRender() should do the
job (because the _myObject field is persistent).

What error? Make sure your user field is not null when the form is

What error? Make sure your user field is not null when the form is
submited. Also make sure you have public getters and setters, because
otherwise Tapestry cannot access them.

Is it that the user object is null on page load?
If so, see the BeanEditForm's implementation of void onPrepareFromForm()

Re: T5 Newbie : populate the value of a form in a bean
The title property of the video object is updated, I don't have a title
property on my page class.
I can't compile anything right now, but I'll try to put together a small
example tonight, if someone else hasn't posted something by then.

Josh It would be really really nice !!!
If you do so I would make it a small wiki tutorial

Hi Michael,
Thanks Josh, but do you have also a title property with getter and

No, I only have the video getter/setter
And if yes (as I guess) whish value is updated when you submit the form
: MyPage.title or MyPage.video.title ?

You can get this to work. I use the textfield component for editing my
bean
objects. This is from a working emplate:
My page class has a getVideo method which returns an object that has a
getTitle method.
Good luck,

Re: T5 Newbie : populate the value of a form in a bean
The t:id attribute is not meant as a way to tell Tapestry what are you
editing: it's just an id that you can use to refer to it in another
component (Label, for example) or in your page class.
Ok you're right but if I try this
I get a failure because tapestry expect an id
Then if I do this
I have to provide the setter and the getter for name and I still get an
error when I submit.
The only thing that work properly is this
But I comeback to my initial question : I just can't populate the value
to the bean directly from the form
The best thing I can do is this
public String getName(){
return user.getName();
}
public void setName(String name){
user.setName(name);
}
