Re: [Wicket-user] How do I do this - several similar links to another page
To help reduce some code, why not extend the BookmarkablePageLink class to
form your JavascriptConfirmLink and then no need to write the onclick().
also try
new JavascriptConfirmLink(id, cls, new PageParameters(method=method1),
msg)
and the id will be used here:
span wicket:id=listViewId
a wicket:id=theLinkId href=anotherPage?method=method1method1/a
/span
You can ignore the href, as wicket will insert it for u.
I'm trying to make a page with several similar links to another page:
a href=anotherPage?method=method1method1/a
a href=anotherPage?method=method2method2/a
a href=anotherPage?method=method3method3/a
This would be really easy to put into my html code, but then it
becomes fragile to whether or not I'm mounting my urls. I suppose I
could just make sure to always mount them and make sure to keep these
links in sync with that mapping. But let's for some reason suppose
that I want to inject these from my java code. I'm not sure how to do
this exactly. I was thinking I could do something like I outline
below. Actually, my links are a bit more complicated than displayed
above, since I would like to make sure to have a javascript
confirmation for each click. So I think that for each link what I
would need would be the class of the page they link to, and a map of
the parameters. So I think the code might be something like:
class JavascriptConfirmLink extends Link {
JavascriptConfirmLink(id, pageClass, params, confirmationMessage) {
super(id);
_pageClass = pageClass;
_params = params;
add(new SimpleAttributeModifier(onclick, return
confirm+confirmationMessage+););
}
onClick() {
setResponsePage(_pageClass, _params);
}
}
Then I'd populate my page with several of these links using this code:
add(new ListView(theLinks, theLinks) {
@Override protected void populateItem(ListItem item)
{
Link link = (Link) item.getModelObject();
item.add(link);
}
});
Does this look correct?
Now I have gotten myself a little confused about a couple of things:
- what is the purpose of the id? Since I will be populating the page
with my links using a ListView, I don't see where the id of each link
will ever be referred to.
Finally, creating these links is quite verbose. PageParameters is
final, so I can't create my links like:
new JavascriptConfirmLink(id, cls, new PageParameters() {{
add(method, method1); }}, msg)
like I'd like so I end up having to new a PageParameters for each link
and add to it before creating the JavascriptConfirmLink, which is
seeming quite verbose.
There may be some holes in my approach. Is there a better way to do this?
Thanks,
Lowell

Re: [Wicket-user] How do I do this - several similar links to another page
That looks pretty reasonable to me (though my code is not in front of
me right now). I like how you can pass a String to 'new
PageParameters()'. A little unexpected but nice (I should have read
the javadoc more thoroughly).
So I have another question: How to you set the link's title? That is,
how do you set the text between the a and the /a?

Re: [Wicket-user] How do I do this - several similar links to another page
Why not just add a label to the link.
span wicket:id=listViewId
a wicket:id=theLinkId href=anotherPage?method=method1
label wicket:id=theLabelIdmethod1/label
/a
/span
add(new ListView(theLinks, theLinks) {
@Override protected void populateItem(ListItem item)
{
Link link = (Link) item.getModelObject();
Label label = new Label( theLabelId, Method-xxx );
// label.setRenderBodyOnly( true );
link.add( label );
item.add(link);
}
});

Re: [Wicket-user] How do I do this - several similar links to another page
You may choose to use almost any html tag for labels.
It's just that the wicket examples all use spans :)

you can also factor out the javascript confirmation into a behavior and
reuse it across any links classes like
Link link=new Link(foo) { onclick(){..}}.add(new
LinkConfirmation(sure?));
BookmarkablePageLink link=new BPL(...).add(new LinkConfirmation(sure?));

String onclick = tag.getAttributes().getString(onclick);

Does this look correct?
Now I have gotten myself a little confused about a couple of things:
- what is the purpose of the id? Since I will be populating the page
with my links using a ListView, I don't see where the id of each
link
will ever be referred to.
Finally, creating these links is quite verbose. PageParameters is
final, so I can't create my links like:
new JavascriptConfirmLink(id, cls, new PageParameters() {{
add(method, method1); }}, msg)
like I'd like so I end up having to new a PageParameters for each
link
and add to it before creating the JavascriptConfirmLink, which is
seeming quite verbose.
There may be some holes in my approach. Is there a better way to do
this?
Thanks,
Lowell

Re: [Wicket-user] How do I do this - several similar links to another page
Igor,
I notice that you call detach() on your models in this example. I have
searched, but can not find where it is written when (or if) we should be
calling detach ourselves. I'm using implementations of
LoadableDetachableModel for my models that hold DB-backed domain objects. I
don't want them to be stored in the session between requests at all. How do
I make sure that happens? Should I be calling detach somewhere implicitly,
or is it handled automatically?
Thank you for all your help - it's amazing how helpful all the core team is
on the mailing list!!

You can ignore the href, as wicket will insert it for u.
I'm trying to make a page with several similar links to another page:
a href=anotherPage?method=method1method1/a
a href=anotherPage?method=method2method2/a
a href=anotherPage?method=method3method3/a
This would be really easy to put into my html code, but then it
becomes fragile to whether or not I'm mounting my urls. I suppose I
could just make sure to always mount them and make sure to keep these
links in sync with that mapping. But let's for some reason suppose
that I want to inject these from my java code. I'm not sure how to do
this exactly. I was thinking I could do something like I outline
below. Actually, my links are a bit more complicated than displayed
above, since I would like to make sure to have a javascript
confirmation for each click. So I think that for each link what I
would need would be the class of the page they link to, and a map of
the parameters. So I think the code might be something like:
class JavascriptConfirmLink extends Link {
JavascriptConfirmLink(id, pageClass, params, confirmationMessage) {
super(id);
_pageClass = pageClass;
_params = params;
add(new SimpleAttributeModifier(onclick, return
confirm+confirmationMessage+););
}
onClick() {
setResponsePage(_pageClass, _params);
}
}
Then I'd populate my page with several of these links using this code:
add(new ListView(theLinks, theLinks) {
@Override protected void populateItem(ListItem item)
{
Link link = (Link) item.getModelObject();
item.add(link);
}
});

Re: [Wicket-user] How do I do this - several similar links to another page
only models that are assigned to component's default model slot are detached
automatically.
you can think of it as component doing this
component { ondetach() { imodel model=getmodel(); if (model!=null) {
model.detach(); }}}
if you keep a reference to a model yourself (say in a field) then you have
to make sure it is detached.
class ConfirmAddRoleToUserPanel extends panel {
private IModel role;
public mypanel(string id, imodel user, imodel role) {
super(id, user);
this.role=role;
}
protected void ondetach() {
// here we need to detach role, user model will be detached for us by
component
role.detach();
super.ondetach();
}
}
one thing to do might be to have something like this:
protected void ondetach() { ReflectionUtils.detachModelFields(this);
super.ondetach(); }
that can make life somewhat easier, although i prefer doing it manually.
