Re: LoadableDetachableModel and load() method question
Hi Warren,
It should not be called twice. Not within the same request that is.
Possible causes:
- you have 2 model instances instead of 1
- there is a bug in Wicket
If you are sure it the latter, please provide a quickstart and add it to
a new Jira issue.
Regards,
Erik.

I have a page that displays a lot of labels and two text field. It is

protected Object load()
{
// Update last Item
// Retrieve next Item
}
Everything works, but load() gets called twice. I understand why that
happens, but I only need it to be called once. I can use a flag to make the
body of load run once, but this does not seem very clean and I can see it
causing problems. Is there a better way to achieve what I am trying to do?

But if the user is filling up a form for a new entity I think I have two options, one serialize and the other create a kind of dto.

That's why I was speaking up. I like wicket and maybe I could find another way. Those other languages are not magical. They still have serializable and non-serializable objects. An object containing a reference to a file handle or database connection will not be serializable in any language. You just don't get to find out that your object wasn't (safely) serializable until you restore it and it starts failing. Java's Serializable interface is just a marker, a way of telling the serialization code that your object does not contain file handles, database connections, or other such things that can't be safely serialized. Since I never put these things in my entities, I routinely mark all my entities as Serializable. I do not consider it a case of the web tier leaking into my domain model (I assume this is what you meant by modified by the web tier). jk - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

clarification on page versioning
I have a page which displays a [login box] (if not logged in) or an info box
[user name|logout link] if logged in.
I implemented this as follows:
User user = BaseSession.get().getLoggedInUser();
if (user == null)
{
add(new Login(login));
}
else
{
add(new CurrentProfile(login));
}
Both Login and CurrentProfile are subclasses of Panel. When the login
form is submitted or the logout link is submitted, in order to get the page
to re-render, I had to use this code:
setResponsePage(getPage().getClass()); // need to use class so
page is re-rendered
As a new wicket user, I'd like a clarification on why this is necessary. If
I used this code:
setResponsePage(getPage());
... which appears to be the default behavior if setResponsePage() isn't
called ... then the page is simply displayed without re-rendering (e.g.,
after login, the login box is still shown). So, my question is what's the
difference between the two? Is there a way to mark a page as needing
re-rendering? Is my solution the correct way in Wicket?
This also raises the question about how many pages are stored in the page
map. For example, if I were to login and logout 10 times in a row ... would
there be 20 pages in the page map? Is there a way to clear out the page map
for a page?
In my case, I invalidate the session on logout, so the above case isn't an
issue in this exact case. I'm more concerned about someone who navigates my
site and visits hundreds of pages. How do I keep the session from filling
up with old pages?
Finally, is there a best practice to debug/monitor session size and page map
size?
Thanks,
-Doug

Both Login and CurrentProfile are subclasses of Panel. When the login form is submitted or the logout link is submitted, in order to get the page to re-render, I had to use this code: setResponsePage(getPage().getClass()); In this case the page isn't re-rendered, it is re-created, i.e. a new instance of your page class is instantiated, which then does the add(new CurrentProfile()) in its constructor. In the default behavior you're getting the exact same page instance you initially created and in which you said add(new Login()). To replace the login panel with the profile panel, keep a reference to the login panel and in your form submit method do this: login.replaceWith(new CurrentProfile()) This removes the login panel from the page and, as the method name suggests, replaces it with the CurrentProfile instance. Remember the latter in a field too, if you ever want to switch back. This way you only have one page and swap out its components instead of creating new page instances.

Be warned though, the biggest bottle neck in this, is the loading of the
data from database.
So for best performance, you should read only one page's worth data at a
time from your DB
(in your case 500).
If you load the whole data, and use some thing like a list iterator, you
will not get any performance
benefit.
Unfortunately ANSI SQL has no syntax for pagination of results. So you
have
2 choices.
1) Keep an open DB cursor , and retrieve as much data as you want per page
rendering. But this
ties your cursor to the user session. Not a very good idea.
2) Use the vendor specific way to get paginated results. Almost all major
vendors support pagination
of query results in their own idiosyncratic way.
If you go with approach 2, you can even use the
AjaxFallbackDefaultDataTable, which will do all the
pagination etc for you, and with AJAX to boost.
You only need to provide a SortableDataProvider, which implements the
size()
and iterate(int lower, int upper) calls. Your size() call should fetch a
total count of items. i.e. select count(*) and the iterate(int lower, int
upper) should retrieve the query results
between lower and upper limit.
And with sortable data provider, you even get sorting for free. (I mean
the
UI, you do have to write
the back end implementation your self).
For my case, I use iBatis for DB access, so it is really easy to write DB
Vendor specific queries and
yet retain the pagination abstraction. If I need to work with another DB ,
I
can easily swap the
pagination query part.
Hope this has helped.

Re: Can I use LazyLoad or something like it with a modal?
Other thing you can use to alert the user in a gmail mode (loading...) is to add an AjaxCallDecorator to the link that pop ups the modal window, and using javascript to show/hide this message Gerolf Seitz wrote: take a look at AjaxLazyLoadPanel. this might do the trick.

I have a modal that has a lot of information in it and it has to get back a large amount of data from the database and it is taking about 4 seconds to load because of all the data.

Anyway when you click on the button to open the modal it takes about 4 or 5 seconds for the modal window to open. I would like to have something like lazyload has come up and show that the application is working and loading the modal instead of the screen just sitting there. If it just sits there while it is trying to load the user will click the button multiple times thinking the application is broken. So can I Lazy load a modal window? Or is there a better approach to tellign the user to wait for 5 seconds for the modal window to open?

Re: clarification on page versioning

RE: problem with DateTextField in wicket 1.3
i tried to modify the quick start and it works fine there.
it looks like it's conflicting with wicketstuff-yui-1.3.0 which is using yui
2.2.2. i did some searching and it looked that someone was working on porting
wicketstuff-yui to 2.3.0. was it completed, if yes, where can i get the
source? i'm using wicketstuff-yui for dropdown menus, is there anything else i
could use to work around the issue?
Thanks,
Vadim

Re: clarification on page versioning
Probably you should move this code in onBeforeRender() (and use
addOrReplace().
This way every time you'll have the right panel.

I have a page which displays a [login box] (if not logged in) or an info box
[user name|logout link] if logged in.
I implemented this as follows:
User user = BaseSession.get().getLoggedInUser();
if (user == null)
{
add(new Login(login));
}
else
{
add(new CurrentProfile(login));
}
Both Login and CurrentProfile are subclasses of Panel. When the login
form is submitted or the logout link is submitted, in order to get the page
to re-render, I had to use this code:
setResponsePage(getPage().getClass()); // need to use class so
page is re-rendered
As a new wicket user, I'd like a clarification on why this is necessary. If
I used this code:
setResponsePage(getPage());
... which appears to be the default behavior if setResponsePage() isn't
called ... then the page is simply displayed without re-rendering (e.g.,
after login, the login box is still shown). So, my question is what's the
difference between the two? Is there a way to mark a page as needing
re-rendering? Is my solution the correct way in Wicket?
This also raises the question about how many pages are stored in the page
map. For example, if I were to login and logout 10 times in a row ... would
there be 20 pages in the page map? Is there a way to clear out the page map
for a page?
In my case, I invalidate the session on logout, so the above case isn't an
issue in this exact case. I'm more concerned about someone who navigates my
site and visits hundreds of pages. How do I keep the session from filling
up with old pages?
Finally, is there a best practice to debug/monitor session size and page map
size?
Thanks,
-Doug
