Re: [Wicket-user] Palette problem with latest snapshot
Ok, here are new details for this.
I was using following form:
from wicket:id=roleForm
input wicket:id=roleName
palette
/form
and java source
EditRoleForm(String str, Role role) {
super(str, new CompoundPropertyMode(role)); ***
add(new RequiredTextField(roleName);
add(new Palette(...);
}
and
class Role {
private int roleId;
private String roleName;
}
Found out that, if I use in line *** instead new PropertyModel(role,
roleName) it works as before.
What I was doing wrong? And why old snapshot accepted my error?
I'm sorry, I did not get to debugging yet, as soon as I'll have some extra
time, I'll do so.
Of course, until someone says, hey it is not worth it ;)

It's easier to diagnose your problem if you provide the
complete source code and markup. But could it be that there
has been a change in the component hierarchy of Palette, and
your own markup is now incompatible with it?
We always use a snapshot of the current day and have
extensive JUnit tests (covering about 90% of the lines).
This makes it a lot easier to notice and fix this kind of
problems, as we can easily see from commits / dev / user
mailing lists what is going on, and just diff the whole
wicket source code when needed. A couple of days of diff is
perfectly readable, but one month not.

Re: [Wicket-user] [Question] wicket.markup.html.form.Radio
Thank you Tong, interesting approach.
I make it work for me by adding AjaxFormSubmitingBehavior to the Radio
component, just to keep in synch the model with the RadioGroup state. But
your solution is more elegant.

Re: [Wicket-user] HomePage url changes when user returns from a second wicket page
Page A has this code in its constructor:
Link b = new Link(b){
public void onClick(){
setResponsePage(B.class);
}
};
add(b);
Page B has a no-args constructor. It has a link to page A. It also has a
form (with a bit of Ajax) which takes some user input. The no args
constructor writes a debug message In constructor of class B.
The user starts on page A, clicks the link to B, enters some data into the
form on B, clicks on the link to A and then clicks on the link on A to go
back to B; all the user's data has disappeared.
In fact, B's constructor has been called twice.
Is it not the case that the setResponsePage(B.class); (as opposed to
setResponsePage(new B());) should use the _original_ instance of B, which
was stored in the user's session (as per the perfectly reasonable post
below)?
How can I achieve the desired effect (ie not losing the user's input on
returning to B) ?
Is the only way to achieve this to manually put the user's input data into
some sort of dumb object, put that dumb object into the session, and then
pass it as a PageParameter when heading back to B ?

No problem. ;-)
Yes, I have a lot to learn about wicket, but I know a lot more than I did
a
few days ago, and I like it so far.
Great!
In my particular case, the page in question is the HomePage, so, since
the
user has already been there on her way to Page2, I suppose I will always
need to create a new instance if I want to show an alert (for example) as
the HomePage is visited from Page2's submit (eg user saved some data
entered
on a Page2 form by hitting submit).
I acheived this, albeit by dubious methods (as you kindly pointed out),
by
including an alert in the head of the HomePage if the constructor that
takes a message (eg HomePage(String successMessage)) is called using a
StringHeaderContributor.
I suppose I need to review this.
On the other hand, it is still a useful learning exercise, either way,
and I
will now study your post in detail before I try again, cheers.
If you wish, you can pass the home page into your Page2.
add(new Link(someId) {
public void onClick() {
setResponsePage(new Page2(HomePage.this));
}
});
And take the Page arg in Page2's constructor.
That way, you have a reference to it, and can link back to that.
It's probably better to do status alert type stuff using Wicket's
FeedbackPanel (if it's for a form) or via some other Session-based
mechanism, though.
Have fun playing.

Al

If you look closely (or using a debugger) you can see that when you do: page.add(new MyPanel(...)); First the constructor is called, and only then the add method. At construction time the parent is not known yet.

If you wish to use a particular page instance, you need to pass it

Re: [Wicket-user] Automatic page history discovery...need direction
I would like to build my own breadcrumb type of navigation widget and I'm looking for some direction as to what I might use to discover what page is currently being served RequestCycle#getResponsePage does a best effort guess for getting the 'current' page. You can only use that method after resolving of the request target (where we determine what kind of request it is). and how I might detect a history of pages leading up to the current one the user is viewing? Would I tap into the page-versioning thing that Wicket does for maintaining the session? That would be possible, but probably not the easiest thing. Do you really want to track all the versions, or would just the plain page requests suffice. In case of the latter, you could work with a base page, and let the constructor register itself for tracking is the session. It might also give you a bit more control of when you actually want to include a page as a bread crumb, and when it is merely an intermediate page. I'm aware that there is a breadcrumb control out there already but I need something a little more simplistic that won't require me creating a bunch of panels. Yeah, the one in extensions works best if you use a lot of component replacements. If you work more page based you might want something else. Please do share if you found a solution you like.

You can try the attribute modifier. Try this:
final Label label = new Label(image);
AjaxLink someLink = new AjaxLink(.) {
public void onClick(AjaxRequestTarget ajaxRequestTarget)
{
AttributeModifier attributeModifier = new
AttributeModifier(src, true, new Model(new path to the file));
label.add(attributeModifier);
label.setOutputMarkupId(true);
.
}
}
I hope it helps. It may not be the best way to do it .. but works for me ;)

Re: [Wicket-user] AjaxLink not updating Image
Also dont forget to :
ajaxRequestTarget.add(label);

Hey Jeremy,
You can try the attribute modifier. Try this:
final Label label = new Label(image);
AjaxLink someLink = new AjaxLink(.) {
public void onClick(AjaxRequestTarget ajaxRequestTarget)
{
AttributeModifier attributeModifier = new
AttributeModifier(src, true, new Model(new path to the file));
label.add(attributeModifier);
label.setOutputMarkupId(true);
.
}
}
I hope it helps. It may not be the best way to do it .. but works for me
;)

I have an AjaxLink link that I am trying to use to update an image, in

also turned off Caching in FireFox. I'm not sure but the XML being sent
doesn't look correct. I'm using 1.2.5. Here are the relevant code

[Wicket-user] how to update component on parent page.
Hi all:
I have scenario:
1) I have a page (say Page1) with a link A and a Image (say img1)
2) On clicking link A, I open a ModalDialog (as a separate page). Say C.
3) There is a AjaxLink on this Page C (ModalDialog), on clicking this link,
I do some processing and close the dialog.
Now the problem is :
I would like to update/redraw the Image img1 (present on the parent
page1).
Issue :
When I do:
AjaxSubmitLink link = new AjaxSubmitLink(someSubmitLink, this) {
/**
* Serial UID
*/
private static final long serialVersionUID = 1L;
@Override
protected void onSubmit(AjaxRequestTarget target, Form form)
{
.(some process)
target.addComponent(the image component img1 passed
to this class);
...(close the dialog)
}
...
The above code does not find the img1 component on this new page and hence
fails to update it.
The ajax debug window shows:
Component with id [[tabs_panel_viewPhotoPanel_zoomLink2_image]] a was not
found while trying to perform markup update. Make sure you called
component.setOutputMarkupId(true) on the component whose markup you are
trying to update.
The img1 has the setOutputMarkupId(true) .
BTW, I am using wicket 1.2.6.
Any ideas?
~Ravi Gidwani.

Re: [Wicket-user] Javascript Error using submit link in 1.3 that didn't happen in 1.2.5
I'm still having this problem on 1.3 snapshot.
Interesting point about the markup (html id attribute). My markup looks like
this:
form wicket:id=formTransaction id=formTransaction
And the generated javascript looks like this:
[a onclick=var e=document.getElementById('formTransaction_hf_0');
e.name='linkAddEntry'; e.value='x';var
f=document.getElementById('formTransaction2');var ff=f;if (ff.onsubmit !=
undefined) { if (ff.onsubmit()==false) return false;
}f.submit();e.value='';e.name='';return false; href=#
wicket:id=linkAddEntry]Add[/a]
the second getElementById always has a '2' appended to it...

That should typically print the stack trace if your logging
configuration is set up properly.

Re: [Wicket-user] how to detect http session expiry - timeout due to no user activity
thats not entirely correct. while the event cannot be pushed to you, you can pull for it. you can set a cookie with expiration null - such a cookie is destroyed when the window is closed. so you can poll for it ad if its gone you know its a new window being opened. in the same manner you can use window.name variable, which is what we do. so when a request comes in and the user has a last_login cookie (set expiratio to 30 mins), but no login_session cookie (which is the one with expiration null) you know they closed the window and are coming back -igor On 6/17/07, Eelco Hillenius [EMAIL PROTECTED] wrote: well, I have a project where the requirement is to do some things when user logs out, otherwise the same user can't use the application for the next 30 minutes.

It would be better than nothing I guess. Eelco - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits.

You might be able to mess with the onbeforeunload event on body.

Re: [Wicket-user] Javascript Error using submit link in 1.3 that didn't happen in 1.2.5

I'm still having this problem on 1.3 snapshot.
Interesting point about the markup (html id attribute). My markup looks like
this:
form wicket:id=formTransaction id=formTransaction
And the generated javascript looks like this:
[a onclick=var e=document.getElementById('formTransaction_hf_0');
e.name='linkAddEntry'; e.value='x';var
f=document.getElementById('formTransaction2');var ff=f;if (ff.onsubmit !=
undefined) { if (ff.onsubmit()==false) return false;
}f.submit();e.value='';e.name='';return false; href=#
wicket:id=linkAddEntry]Add[/a]
the second getElementById always has a '2' appended to it...
It's possible that Igor has just fixed this. Worth trying again, at any
rate.
