Re: Wicket-1.3-beta2 validation (conversion) bug?
I found a quick fix for my issue: instead of disabling the Textfield, I make
it readonly... still wondering why the change has been made in the convert()
method.

Please help!

After migrating from wicket-1.2.6 to wicket-1.3.0-beta2 I had the

application throws ConversionException when trying to convert a null

I've take a look on the convert() method of the FormComponent class
and
noticed the difference from the 1.2.x branch which may cause the
issue:
This snippet of code is from 1.3.0-beta2
[CODE]
if (typeName == null) {
//string conversion code
} else {
//type conversion code
}
[/CODE]
This snippet of code is from 1.2.6
[CODE]
if (type == null) {
//string conversion code
} else if (!Strings.isEmpty(getInput())) {
//type conversion code
}
[/CODE]
As you can see, in the 1.3.0-beta2 version, the conversion does not
check
if
the getInput() is an empty string before performing type conversion. I
wonder if it is a bug, or it is something that I missed?
Thank you!

Ajax refresh of DefaultDataTable in wicket-phonebook
For some reason when I do an ajax refresh of the DefaultDataTable in
wicket-phonebook, the FilterToolbar disappears. I see it in the Ajax
Debugger, but it doesn't display on the screen. This is only
happening in FF, not IE (only tested on WinXP).
I cannot see any difference between the html that is rendered when the
page is loaded vs. when the ajax refresh happens. But FF decides to
not render the FilterToolbar after the ajax refresh, while IE does
render it.
I'm wondering if FF has issues with invalid HTML? The FilterToolbar
puts a form around a tr/tr and adds a span inside the form, but
outside the tr/tr. However, I don't understand why it would only
have a problem after the ajax render and not the original page render.
Here are the only code changes to ListContactsPage::
public ListContactsPage() {
addCreateLink();
IColumn[] columns = createColumns();
// set up data provider
ContactsDataProvider dataProvider = new ContactsDataProvider(dao);
// create the data table
final DefaultDataTable users = new DefaultDataTable(users, Arrays
.asList(columns), dataProvider, 10);
users.addTopToolbar(new FilterToolbar(users, dataProvider));
users.setOutputMarkupId(true);
add(users);
add(new AjaxLink(refresh) {
@Override
public void onClick(AjaxRequestTarget target)
{
target.addComponent(users);
}
});
}
And add this to the markup:
a href=# wicket:id=refreshRefresh/a
Note that this is a simple case to illustrate the problem. In my
case, I'm using ModalWindows to edit the data, and on window close,
the data table is refreshed.
Any idea what is causing this? Is it the invalid markup? Any
thoughts on a solution?
Thanks,
Tauren

Using non-string parameters in HibernateContactFinderQueryBuilder
I have a data table based on wicket-phonebook, but have added an
additional column that contains non-string data. In the database, the
value is an int, but the application maps that to a string using a
custom enumeration type with a converter to handle all this.
The table display, editing, and so forth of the data table works fine.
And I have the FilterToolbar showing a choice list of the possible
values in the enumeration. When one of the values is selected, the
rows with that value are displayed.
The problem is that HibernateContactFinderQueryBuilder assumes all
filter parameters are strings. So I've hacked it to work by letting
the int get converted to a string:
private void addEnumCondition(StringBuilder hql,
Enumeration enumeration, String name) {
if (enumeration != null) {
hql.append(and target.);
hql.append(name);
hql.append( = ? );
parameters.add(+enumeration.getValue());
types.add(Hibernate.STRING);
}
}
Obviously, this isn't very elegant. But I'm unclear on what would be
a better approach. I tried to use a ListObject instead of
ListString, but then I ran into other exceptions and didn't dig into
them deeper.
Plus, I'm having problems with the filter choice not persisting the
last selected value like it does for the Last Name column. It always
goes back to Choose one..., even if the table is filtered with a
value from the enumeration. And selecting the blank row in the choice
list results in no data rather than all data.
I guess I'm looking for some suggestions or ideas if anyone has any.
Thanks,
Tauren

updateing a component on AjaxTabbedPanel
Hi there,
i am very new to wicket an got some problems while using a tree and a
AjaxTabbedPanel.
I want to update a simple label component at an AjaxTabbedPanel after the
user click something at the tree.
Here is my code:
public class ConfirmPage extends WebPage{
public ConfirmPage()
{
super();
//user is a simple POJO
User user = new User(test,test);
//Elements for the Tree
ListConsUnit consUnits = new ArrayListConsUnit();
consUnits.add(new ConsUnit(Single));
consUnits.add(new ConsUnit(General));
consUnits.add(new ConsUnit());
//simple label at the webpage
label = new Label(luname,user.getUsername());
add(label);
//create the tree
TreeModel tm = MyBaseTree.createTreeModel(consUnits);
tree = new MyTree(tree,tm);
add(tree);
tree.getTreeState().collapseAll();
//create the tabs like the sample app
tabs.add(new AbstractTab(new Model(first tab))
{
public Panel getPanel(String panelId)
{
return new MyPanel(panelId);
}
});
tabs.add(new AbstractTab(new Model(second tab))
{
public Panel getPanel(String panelId)
{
return new MyPanel2(panelId);
}
});
tabs.add(new AbstractTab(new Model(third tab))
{
public Panel getPanel(String panelId)
{
return new MyPanel3(panelId);
}
});
tpanel = new AjaxTabbedPanel(tabs, tabs);
add(tpanel);
add(new StyleSheetReference(pageCSS, getClass(),
css/style.css));
}
Here is now the code from the tree:
public class MyTree extends LinkTree{
public MyTree(String arg0, TreeModel arg1) {
super(arg0, arg1);
}
protected void onNodeLinkClicked(javax.swing.tree.TreeNode node,
BaseTree tree, AjaxRequestTarget target)
{
//update the label on ConfimPage
Label label = new Label(luname,node.toString());
label.setOutputMarkupId(true);
page.addOrReplace(label);
target.addComponent(label);
//how to update AjaxTabbedPanel???
}
}
Here the code from MyPanel:
public class MyPanel extends Panel{
private Label label;
public MyPanel(String id) {
super(id);
label = new Label(test, Text);
label.setOutputMarkupId(true);
this.add(label);
}
}
The label at ConfirmPage is updated via Ajax if the user selects something
from the tree, but not the label at the AjaxTabbedPanel.
If the user selects something from the tree the label at MyPanel should be
updated with the value of the tree node.
How do i do this?

What is the proper way to replace the containing panel from a
control within that panel? I found similar questions posted on
this list, but I haven't got any of those solutions to work for me.
I think you just need to do target.addComponent(getParent()) instead. If
the parent contains too much (like the whole page), then put your Panel
inside another Panel, a Fragment, or a div tied to a WebMarkupContainer.

Dynamic Markup?
I am writing an open source Wiki component for Wicket.. http://sourceforge.net/projects/wicketwiki I've recently started it so it is still in the development process. I want to make it work completely off of AJAX in order for the component to be completely autonomous without effecting the other components it could be grouped with inside an application. Right now, all it does is allow you to edit/render a single wiki page with no interwiki links. I accomplish this by simply just using a Label and not escaping the HTML that is rendered from my wiki engine. The problem is that if I want interwiki links I'm going to have to be able to dynamically create and add AjaxLinks from the rendered HTML markup coming out of the wiki engine. I need a way that I can create my own Markup file/stream/whatever and have my custom component use that dynamic markup instead of searching for a valid .html file in the classpath. Does anyone know what I should look into? Brian Gorman
Antwort: Re: updateing a component on AjaxTabbedPanel
Well ok.
I tried it this way:
public class MyTree extends LinkTree{
public MyTree(String arg0, TreeModel arg1) {
super(arg0, arg1);
}
protected void onNodeLinkClicked(javax.swing.tree.TreeNode node,
BaseTree tree, AjaxRequestTarget target)
{
Label label = new Label(luname,node.toString());
label.setOutputMarkupId(true);
page.addOrReplace(label);
ConfirmPage page = (ConfirmPage)tree.getWebPage();
AjaxTabbedPanel tpanel = page.getTpanel();
MyPanel panel = (MyPanel)tpanel.get(panel);
Label label2 = new Label(test,TestText);
label2.setOutputMarkupId(true);
panel.addOrReplace(label2);
target.addComponent(label);
target.addComponent(label2);
}
}
It works so far, but is this really the right way?
How do I access the MyPanel which is included in the AjaxTabbedPanel?
I don't think that MyPanel panel = (MyPanel)tpanel.get(panel); is the
best way.
Any suggestions?

Re: image overlays, what's the best solution ?
Okay, I found a solution based uniquely based on ResourceReference for both the original icon and the decorators to be applied. If anyone's interested, let me know it and I'll post some code. Cheers, Antoine. Antoine Angénieux a écrit : Hi guys, I've been using Wickets for over 6 months now and absolutely love it! I'm developping on Wicket 1.3 beta 2 and was looking for the best solution to provide some kind of composite ResourceReference... What I want to achieve is building complex icons by superposing them on top of each others (imagine an icon in a tree that could be decorated by an error mark and / or a signed, rejected mark or whatever you can come up with). Furthermore, I'd like the resulting image to be accesible by an URL that does not require bookmarkability... My source icon to be decorated is available as a Wicket ResourceReference. One way I found interesting was to build this on top of RenderedDynamicImageResource and do the overlaying in the render(Graphics2D graphics) method, but I could not find a reliable method to wrap the data from my source icon ResourceReference into either a comprehensive byte array for the awt Toolkit to build an image, or more simply directly an awt Image from the resource.getResourceStream().getInputStream().

Subject: Wickest way to format a label before render
To: [EMAIL PROTECTED]
Hi, I have the dumbest request from our functional team.
A label that holds the result of a calculation must invert the positive
negative sign (- +), with that the color, and add a percentage symbol.
So, basically I have to change the display model value and based on the
model value itself.
onBeforeRender?
I had some difficulties,
thanks,

Re: Caching the context path
so what exactly are you doing? obviously you cant really share an app across
actual contexts because they are supposed to be isolated.
so what do you do? you have a single application object, but you map two
filters with two different paths and share the single instance of
application object via custom applicationfactory?

Hmmm...
Very nasty things are happening in my forms. Because it's not resolving
the URLs properly, wicket thinks that my pages are expired.
Does this mean that I have no choice but to re-instantiate a new wicket
for each context?
In other words, is what I'm trying to do too much to ask of wicket
without some major changes?
Or is there a relatively simple way I could get this to work?

I'm attempting to mount one instance of wicket on more than one context

Wicket, due to some kind of caching going on.
Essentially, I have my servlet container setup so that both of the
following get routed to the same instance of wicket:
www.example.com/cxt1/
www.example.com/cxt2/
On the first run, both work as expected.
If I try to access directly either one of:
www.example.com/cxt1/somePage
www.example.com/cxt2/somePage
also no problem.
However, if I first access cxt1, then later try to access:
www.example.com/cxt2{/}
Wicket is forwarding me back to:
www.example.com/cxt1
And vice-versa when I first access cxt2 and later try to access cxt1
without a path.
Also, none of my links are working as expected. Once cxt1 is cached, all
my links now point to that context, which messes up what I'm trying to
do.
Is this a bug? If so, where should I look to fix this?
Thanks!

Eelco, the ISessionStore interface has a lot of methods.. can you give me an example of how to get rid of the serialization? It really slows down the application. I can imagine those checks did cost something in 1.2, though with Wicket 1.3 and the way we use it with the session stores should be pretty well optimized. I think the last time I looked, serializating and saving a (pretty big) page took 1 or 2 miliseconds on my notebook. Are you sure this is such a bottle neck? Maybe there is something else you weren't aware of? Can you give us some numbers maybe? Anyway, if you want to build a session store from scratch, you could look at HttpSessionStore, copy most of it, but instead of storing in the session, you you store it in a hashmap.

Re: wicket:child in a WebMarkupContainer
@ core-devs: The solution that first came to mind was to override add(Component) in SuperComponent so that it would add the added component to myContainer instead of 'this'. Unforunately, the add method is final (why!?), so this can't be done. the javadoc for MarkupContainer#add(Component) should be changed because it's final, but it says * Be careful when overriding this method, if not implemented properly it * may lead to a java component hierarchy which no longer matches the * template hierarchy, which in turn will lead to an error. , when overriding is simply not possible at the moment. gerolf
Re: Order-Items master detail page
you create a new instance of itemsDataProvider but your listview never gets
that new instance, so its using the old one. instead you should change the
data that instance returns:
IDataProvider itemsDataProvider = new idataprovider() {
count() { if (selected==null) return 0; else return selected.items.size();
}
iterator() { if (selected==null) { return new EmptyIterator(); } else {
return selected.items.iterator(); }

Re: Updates within Panels in datatable
I hadn't but I just tried it and no difference. The issue is that when I type
into the textfield the value of amount is not changed. Do you have any
idea why this would be? I do resue the textfield twice setting it invisible
once because if I don't add it to the second row I'll get an exception
because the markup expects an object with that wicket id. I only need it to
show along with the first choice in the radio group. Should I be doing this
panel differently?

Re: Wicket vs. ZK
I searched the threads on this forum but didn't find any discussion on comparing Wicket with ZK (www.zkoss.org/), the #1 Ajax project on sourceforge.net now. I read a lot on both frameworks and they both seem nice from the feedback of the users. Since I am about to choose one web framework, I want to get some ideas of these questions here. The main idea behind Wicket is to provide a plain old Java programming model, and this is very different from declarative, DSL based frameworks like ZK (though ZK has an 'advanced mode' where you can write components using Java). Most telling is maybe this quote: TY: Echo2 assumes UI designers are Swing programmers, while ZK assumes many of them are not programmers. , from ZK's creator in an interview you can find here: http://blogs.pathf.com/agileajax/2006/06/an_interview_wi.html. Wicket assumes that UI designers are *designers* (and not half-programmers like ZK assumes) only dealing with laying out, and that UI logic can best be coded in Java (by programmers obviously). Wicket enforces a rigid separation of those concerns (presentation and logic), not because we are born zealots, but because most of us have gone through the experience of how easily you can pull your project in the swamp by even allowing for minimal scripting. In that respect, ZK is counter to what we stand for if you look at the database code here: http://www.zkoss.org/doc/tutorial.dsp Don't get me wrong, I think ZK has a couple of nice features. I'm not crazy about XML, but choosing XUL makes sense from their perspective, and the first part of their tutorial which builds up the lists actually looks nice (though you could achieve the same by e.g. picking up http://developer.yahoo.com/yui/datatable/ with whatever server side framework you like). 1. Design concern (Wicket vs. ZK) Both frameworks are thin-client and generate AJAX, the biggest difference is Wicket uses Java and HTML while ZK uses XUL or other scripting language. What's the advantage and disadvantage in both cases? Advantage of HTML is that you can work with web designers standard tools for laying out and that you have very direct control of what will be in your users' browsers. XUL might be nice if the framework can decide to send it directly to the client if that supports it. Note btw that Wicket is not an Ajax framework. It has - I believe - excellent Ajax support, but you can build web applications without any Ajax just fine. 2. AJAX components (Wicket vs. ZK) From the demo websites, it seems ZK provided more AJAX components than Wicket. (As I haven't worked deeply with Wicket, it could be Wicket either provided more components or easy to write those components.) But I am wondering is it easy to use Wicket to implement features like drag and drop, date picker... I think it is more relevant to first look at how easy it is to create your own, and second look at exactly what components you need and which are supported. 3. Target application (Wicket) There is a trend to move from multi-page application to single-page application (or a few pages which much lesser than traditional page-based web application) using AJAX. As far as I know, Wicket is a component-based framework and very OO, which means the components could be well reused and maintained, but is it easy to build such single-page application? Would one or a few more page classes be very large? Whatever you want. No, they wouldn't be large, as you would design panels for sections of a single-page app, and add/ replace those panels based on app logic. 4. Integration (Wicket) How about using Wicket together with existing JSF application? There are no such facilities atm, though if you google you should be able to find a couple of examples of where people mixed JSP Wicket.

Re: Wicket vs. ZK
On 8/15/07, juliez [EMAIL PROTECTED] wrote: First, thanks for the reply! 2. AJAX components (Wicket vs. ZK) you do not implement features like drag and drop or datepicker in wicket, instead you wrap javascript libraries that implement those features with wicket components. I am actually confused at how many ways Wicket supports AJAX. The classes in wicket.ajax packages are used for AJAX behaviors. I supposed these classes are for common AJAX behaviors. wicket has an excellent native ajax support. it allows you to perform partial page renders where only one or more components on the page are updated. see wicketstuff.org/wicket13 for examples under ajax. it also has common ajax handlers - so you dont have to reinvent the wheel - such as form component update, ajax form submit, self updating timers, etc. It seems they are different from wrapping JavaScript - correct me if I am wrong. javascript is not the same as ajax. take drag and drop - that has very little to do with ajax except maybe for notification that x has been dropped into y. take datepicker, that has no ajax in it at all, its just javascript that draws a calendar and puts a selected date into a textfield. Then my questions are 1) what is the standard way to add AJAX with Wicket: first looking for existing components (including the components in WicketStuff), then if not found, wrap JavaScript? if you have some ajax need that wicket doesnt natively provide and that is existent in some 3rd party js lib then you can easily write wicket wrappers for it. the nice thing about it is that you only have to do it once, and from that point on you dont need to worry about javascript, just use your java classes. for example there is wicketstuff-animator project that wraps animator.js in a set of wicket components. you can add animations without known the details of the animator.js lib. 2) I read the attached file and googled more for the instruction on how to wrap JavaScript. Found one here (http://cwiki.apache.org/WICKET/adding-dynamic-field-prompts-or-hints.html ). I am wondering if there are instructions on how to do it in a general way. there is no general way, you simply write components that hook into the javascript. 3. Target application (Wicket) like you say, wicket is component oriented. it doesnt really care how you build your app: many pages or a single page. at my day time job we have an app that is mostly a single page with a lot of component replacement. works just fine. Still not sure, if a page includes many replacement, how to keep the method/class short yet support those changes? you dont define the combination of all possible replacements at the same time. wicket is dynamic, at any point in time a component can replace itself or other components with something else that was just instantiated. also because components are encapsulated they can perform replacements inside themselves as well. wicket is not page-centric. -igor
