[Wicket-user] DefaultPageFactory
Could DefaultPageFactory be made Serializable? I'm trying to delay page creation, but for me that includes having a PageFactory in the Session instead of a Page. Am I doing something that probably shouldn't be done?

[Wicket-user] AbstractChoice
It appears there is no way to set the choices in AbstractChoice except via the constructor. Can someone add a setChoices() method or let me know if there is a workaround? My problem is that I have a subclass of DropDownChoice that needs to add a choice to the list of Choices passed into the constructor, however, it doesn't appear that I can do that: super(...) has to be called first.

[Wicket-user] Page expired error
Hi. I'm getting a page expired error and I don't know why. I'm using wicket RC2. Every page expires on 10th reload. This only happens with internet explorer. Mozilla and Opera can reload the page as many times as needed with no problems. No other pages are created or reloaded, but the page still expires. This doesn't happen with wicket examples. I'm kind of confused, as far as I can tell my Application class and Page classes don't do anything differend then classes in wicket example, but the expiration happens no matter what. Any hints? Thanks. -Matej --- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?

Re: [Wicket-user] AbstractChoice
You want it? You got it!
It's in HEAD, but as it will take a couple of hours for ssh cvs to sync
with pserver cvs, I attached the fixed file.

[Wicket-user] new model CachingHibernateObjectModel
I'm not sure how many of you are using the wicket-stuff projects, but I just introduced a new hibernate related model: CachingHibernateObjectModel. For anyone using HibernateObjectModel: consider this model if you have edit pages that work with several roundtrips (working on the object) before actually saving changes to the database. I also introduced parameter 'unproxy' in HibernateObjectModel, that unproxies the loaded object. This solved some cglib issues I had when using Hibernate 3.0.

Re: [Wicket-user] new model CachingHibernateObjectModel
Thanks Eelco. I'm not doing Hibernate, but I noticed that my CayenneQueryModel (which I will commit to wicket-stuff someday) seems to be constantly refetching my query. I'll be curious to see how you do the caching.

Re: [Wicket-user] Frames and AJAX stuff
I think we discussed this before, but isn't there a way to configure
javascript or something equivilent which will notify the server right
before the client window closes?

Hi,
Dan Gould wrote:
Three quick questions getting started with Wicket (I'm sure I'll have
more
later, but I'm glad to document what I learn on the Wiki--I like
documenting what I discover). I've only started playing around but,
assuming that a few things can be handled, I think I'm going to choose
Wicket:
1) In one place, my site needs to use frames. (Yes, I know they're
unpopular, but it is important here). There will only be one nav/control
frame while the other will just contain content). Will this cause any
problems with Wicket? Can I use the existing Models to do this?
Using frames won't cause problems with models etc. It can however cause
problems with 'expired' pages. Wicket holds a list (or actually a map)
of page instances in your session (how many depends on your
configuration, ApplicationSettings.maxPages), but defaults to 10 - which
is problably higher than you need. Anyway, in some cases, like when
working with frames, you want to have seperate lists. This is supported
by Wicket by using the 'pagemap' parameter. If this parameter is not
used, it will use it's default pagemap (that's probably what you want to
use for your 'main' frame).
Here's an example of how you could set up your frames:
!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Frameset//EN
http://www.w3.org/TR/html4/frameset.dtd;
HTML
HEAD
TITLEA simple frameset document/TITLE
/HEAD
FRAMESET cols=20%, 80%
FRAMESET rows=100, 200
FRAME
src=myapp?pagemap=leftframebookmarkablePage=mypackage.MyNavigationPage
FRAME src=myapp?bookmarkablePage=mypackage.MyMainPage
/FRAMESET
FRAME
src=myapp?pagemap=bottomframebookmarkablePage=mypackage.MyStatusBarPage
/FRAMESET
/HTML
That's it. Page maps are created automatically, and all links etc of a
page that was created for a certain page map will keep on refering that
page map.
I'll put this example on our Wiki.
2) I am going to be doing some basic AJAX stuff. I know that Wicket
doesn't yet have formal support for it, but I presume that loading some
mini-pages via XmlHttpRequest from some Javascript in my pgaes won't
break anything? Correct.
I haven't tried this myself, but that should work. Please join our
discussion (on the Wiki/ in issue db) about AJAX :) We'll probably start
working on this in the beginning of June.
3) I want to maintain state for my users when the come back, but I don't
want them to have to register. I assume I should get/set a cookie using
the RequestCycle's WebResponse?
I think Wicket even has a more sophisticated support for cookies.
Juergen knows all about it (but I think he's still in Egypt?), but you
can take a look at the signin panel of wicket-examples, and class
wicket.markup.html.form.persistence.CookieValuePersister.
If I understand and read well, you can persist any form component you
want, using any persistence strategy you want - thus including using
cookies. This is in FormComponent:
/**
* Whether this form component should save and restore state between
* sessions. This is false by default.
*/
private boolean persistent = false;
and this is in Form:
/**
* Gets the form component persistence manager; it is lazy loaded.
*
* @return The form component value persister
*/
protected IValuePersister getValuePersister()
{
return new CookieValuePersister();
}
So, it looks like the only thing you have to do is mark the fields you
want to have persisted with a cookie is setting the 'persistent'
property to true.
[BTW: When you do work on AJAX support, I highly recommend using the
DojoToolkit. It's just getting underway, but it has a huge amount of
support in the Javascript/DHTML world and will probably become the de
facto standard. I also mentioned this on the Issue Tracker.]
Thanks. From what I've seen, I like DojoToolkit.
Thank you very much!
