Wicket AutoComplete example does not work
I just looked at the wicket autocomplete example at http://www.wicket-library.com/wicket-examples/ajax/autocomplete?0 does not work in IE8 or Firefox.

Wicket ListMultipleChoice or DropDownChoice with code/decode
For some reason I am finding that most Wicket examples have select box examples that offer single dimension arrays. But most lookup selection use cases I've ever encountered use a short key or 'code' that the user does not see, and then a longer descriptive 'decode' for the user. The classic being a state lookup using the postal code (MD, NY, FL, etc) but showing the user a state name (Maryland, New York, Florida respectively). What is the usual way to do this?

ModalWindow parameters
I am popping up a modal window when an ajax event fires. The event has a parameter of which key the user selected. I know I can get the parameters from the AjaxRequestTarget in the onClick event, but in ModalWindow.PageCreator.createPage(), how can I get the parameters so that I can load the right record into the popup?

AbstractAjaxBehavior and second request
I have a javascript widget on my page that will issue multiple requests. I am using an AbstractAjaxBehavior and priming the javascript component with the uri from getCallbackUri(). First request works flawlessly. But the next request using the same uri (excepting the extra parameters that the javascript widget tacks on), and it is not getting to the onRequest() method. I can confirm that the request is going out because I can see it in firebug. first request: http://localhost:9080/ManagementCenter/?wicket:interface=:7:subscriptionList::IActivePageBehaviorListener:0:&wicket:ignoreIfNotActive=true&_dc=1335302423707&page=1&start=0&limit=20&group=%5B%7B%22property%22%3A%22RECIPIENT_USER%22%2C%22direction%22%3A%22ASC%22%7D%5D&sort=%5B%7B%22property%22%3A%22RECIPIENT_USER%22%2C%22direction%22%3A%22ASC%22%7D%5D second request: http://localhost:9080/ManagementCenter/?wicket:interface=:7:subscriptionList::IActivePageBehaviorListener:0:&wicket:ignoreIfNotActive=true&_dc=1335302444162&page=2&start=20&limit=20&group=%5B%7B%22property%22%3A%22RECIPIENT_USER%22%2C%22direction%22%3A%22ASC%22%7D%5D&sort=%5B%7B%22property%22%3A%22RECIPIENT_USER%22%2C%22direction%22%3A%22ASC%22%7D%5D I see the wicket:interface portion in there.

AbstractAjaxBehavior and ModalWindow
I have a page where I show a javascript widget. Based on events in said widget, I may fire one of five different ajax events. On some of them, I am required to show a modal window with a form in it. I am using, based on advice found while googling, AbstractAjaxBehavior to handle the ajax events, which is working swell for the non-modal window events. But ModalWindow (the wicket extension) wants an AjaxRequestTarget passed to the show() method. Unlike the example which uses a link to trigger the modal window, AbstractAjaxBehavior does not pass an AjaxRequestTarget for me to pass along to the show() method. I tried to pass along the request from the RequestCycle, but that got me the following ClassCastException: java.lang.ClassCastException: org.apache.wicket.request.target.component.listener.BehaviorRequestTarget incompatible with org.apache.wicket.ajax.AjaxRequestTarget Brian Mulholland - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

But as you get into it, all kinds of little problems arise. For example, Ext wants it's form in place instead of the basic HTML form, Ext controls often want to tie into a separate data source, making the JS controls breaks alot of Wicket's behaviors which are geared towards markup, and so on. The devil is in the details. As i said, each individual hurdle that presented itself I was able to overcome, but as time went on, I began to feel like I had a package full or workarounds. >> I would really love it if a more experienced Wicket developer took a >> serious crack at creating a Wicket extension that worked with rich >> internet controls.

I saw WiQuery and JQWicket...but didn't really seem to me to be geared towards a full integration as much as a collection of random stuff for specific web use cases. I wasn't familiar with the others. I'll go look at those. > I guess these use different approach to integrate Wicket with the JS > widgets. Pick the one that you like the most and make it better. Perhaps once I am more deeply familiar with Wicket I would be confident enough to try to extend something for public consumption, but I don't really feel experienced enough to do things Wicket's way. And Wicket seems like one of those frameworks that really wants you to know the "right way". I probably shouldn't have attempted this until I'd had a few years of development time in Wicket first. But since Ext is basically a component hierarchy and Wicket is basically a component hierarchy, it SEEMED like a perfect fit. And to some extent i still believe it could be...in the hands of a more experienced Wicket developer. > There are talks about making official integration of Wicket with > JQuery UI, i.e. maintained by Wicket core developers but so far there > is nothing done on it. I read some of those threads. I think this would be an excellent idea. Accessibility is a BIG deal for my contract (US Govt), and many jQuery widgets aren't ARIA enabled, so I would gently prod those thinking about it to keep an eye on accessibility if they decided to do this. Try to pick jQuery components that support ARIA. I think the world is going this way. Users expectations of browser interfaces are increasing quickly. If Wicket were to come to market with it's strong object-orientation (the selling feature that attracted my contract), and more rich client features built in (like the various GWT frameworks, but not using that javascript generating methodology), I think it would capture a space most other web frameworks aren't as well positioned to exploit. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Freemarker+ExtJS vs Wicket questions
As a Wicket neophyte myself I can't comment on most of this, but we
did just look deeply into the notion of subclassing components for the
purpose of making them render as rich text widgets from ExtJS. Having
just done that I will say that there are ALOT of little hidden nits
and difficulties that come up in such an effort. Wicket and ExtJS
both want to control the rendering of the end markup, so when you
replace the generated markup with Ext widgets, many of Wicket's little
pre-created solutions for various internet use cases breaks. Each
problem is circumventable, but eventually you find yourself almost
writing your own framework rather than extending a framework.
I would really love it if a more experienced Wicket developer took a
serious crack at creating a Wicket extension that worked with rich
internet controls. I get the feeling that my effort failed as much
because I didn't have deep Wicket knowledge as anything else.

jQuery Validation & Wicket
There is a javascript jQuery client validation framework (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) that I tried to integrate with my wicket pages. Ran it in a local simple htm, and it worked fine. I put i into my wicket page and form and it does not. No indication of javascript errors or any reason for failure. Has anyone used this lib with Wicket? Does it not work with Wicket? The objective is to simply use a client side validation to give quick feedback on errors, while still enforcing them on the server. I know Wicket has it's ajax validation behavior, but i don't want to issue an ajax request for every component. This library seems like it should intgrate fairly seemlessly relying on simple css classes to define rules. And yet, it does not. Anyone know why?

Re: WiQuery vs JQWicket
Nevermind, found it at wicketstuff: (http://wicketstuff.org/grid-examples for future seekers). But the demo doesn't have source nearby like other wicketstuff demos. Does inmethod grid support remote sorting, or is that sorting I see local? In a paged grid, sorting really has to be remote. Also, what about things like client side validation? Has anyone done a Wicket extension that does client validation?

Re: Wicket and ExtJS
First, thanks for the prompt response.
Okay, so I am struggling with writing a menu component. I saw the
Suckerfish menu example and tried to adapt that towards my needs. I
want my fellow developers to be able to write something like:
MyMenu topMenu = new MyMenu("topMenu");
MyMenu subMenu1 = new SubMenu("subMenu1", "Here is a submenu");
MyMenu subMenu2 = new SubMenu2("subMenu2", "Here is another submenu");
subMenu1.addMenuItem(new BookmarkableLink(LINK_ID, SomePage.class),
"Some Page");
subMenu2.addMenuItem(new BookmarkableLink(LINK_ID,
SomeOtherPage.class), "Some Other Page");
submenu1.addMenuItem(new MyMenuSeparator());
subMenu1.addMenuItem(new Link(LINK_ID) {
public void onClick() {
//do something
}
}, "An action");
subMenu1.addMenuItem(new MyClientSideAction("Do Local Work", "some
javascript code or the name of a client side function to invoke or
something"));
subMenu2.addMenuItem(new Link(LINK_ID) {
public void onClick() {
//do something else
}
}, "Another action");
subMenu2.addMenuItem(new MyClientSideAction("Other Local Work", "some
javascript code or the name of a client side function to invoke or
something"));
Which would then generate Ext code. Either as one large block using
the Ext JSON config objects (if you've ever seen Ext code you know
what I mean), or generating a series of smaller scriptlets each
generating the indiidual item needed and adding by name to the
component that is it's parent.
The former might look like this ("m just typing this now so forgive
any typoes).
Ext.onReady(function() {
//some code to make parent components not shown until we get to it's
items array which might look like:
items: [{
xtype: 'menu',
items: [{
xtype: 'menu',
text: 'Here is a submenu',
items: [{

the second proposal might have independent script tags at each
wicket:id tag, replacing the element with a script tag that gets the
parent (as detected by the parent hierarchy in wicket) and adds the
component to it's parent. Because Ext stores each function and
executes it in order, it should have the same effect as above, but
allow the component to be more independent. It only needs to detect
it's parent. I like this style better, but I have less idea how to
implement it through wicket. How can I override what wicket writes
for it's body?
So I would end up with many small block like the following throughout
my rendered markup.
Ext.onReady(function(){
var parent = Ext.getCmp("myParent");
parent.add(Ext.create("whatever we are creating", {
//the config parms
});
});
Since I don't know how to do that, I have been writing towards the
first example. the result of my stumblings is a set of components
that all implement an interface that asks for the snippet of the first
example that represents their contribution, and then adds it as a
header contribution to the page. Links are resolved by css styling
the markup wicket generates as display:none, and then using javascript
to pick up the link and text of the menu item to add after render.
But this solution feels 'hacky' and inelegant. It feels like I am
sneaking around the framework, not USING the framework.
As to jQuery. I know zilch about jQuery. Because I also am just
learning wicket, I am leery of getting 'sucked into the rabbit hole'

Wicket and ExtJS
So I am on the verge of giving up on integrating Wicket and ExtJS and going with some other webapp framework. I thought Wicket and ExtJS would be the perfect companions because Wicket is basically a hierarchy of components and so is ExtJS. If I could extend wicket components to write out the required javascript instead of their HTML (or even in addition to), it would be a perfect fit. My developers wouldn't need to be expert javascript developers as long as enough of us were to maintain the components. The developer could simply snap in an extended component in Wicket, and like magic, a beautiful full-featured UI widget appears in their browser. The problems I am having are probably mostly from my Wicket inexperience. I just cannot figure out how to make components that do what I want. I try using header contributors to write out the javascript, but many wicket values (like the links generated by the link components) don't seem available in the page. I envisioned being able to override a method in an extended component to write out what I wanted to write like myComponent.writeMe() to write out what I wanted to write out. But that seems like it's not how Wicket works. I am presently overriding onBeforeRender at the page level, iterating through child components looking for an interface I hung on my extended components, and calling methods to get javascript contributions from them, and then adding a header contributor to the page. But this feels like I am ESCAPING the tool, not using it. And the strict Wicket component to markup structure is frustrating because ExtJS 4 builds components solely through javascript. It feels like Wicket is fighting me every step of the way, and that screams to me that I am misusing the tool. Has anyone done something like this in Wicket? Can anyone provide some guidance? Am I approaching the problem from the wrong perspective? Brian Mulholland - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Validation
The two are added to the same component, but have no direct relationship to each other. It IS true that the non-working one is added 2nd. However in the test where I am trying to get control to the 2nd one, I typed input that did not evoke a message from the first validator. But could you elaborate on that point? Do you mean that the order in which I add validators dictates the order in which they execute and that when a validator fails, others are not executed? Does that rule only apply within the component? And do form validators run if a field validator fails? I've been looking around for details like this, and all I see are highly simplistic examples about required checks. I never seem to find an in depth discussion about when validators fire, how they interact and so forth. Where is this info discussed?

Validation
I have two validations on a textbox. One is extended from the EmailValidation class that comes with wicket and works fine. The other is an extension of AbstractValidator. That one never gets called. It never gets to the onValidate(). Why would one validator get invoked and function perfectly while the other got ignored? Both were added to the component.

Validation Messages
This is probably a stupid question, but when I set up a validation like required or a custom validator, I want the "label" in the message to reflect a value other than the Id of the component.

Re: Wicket Panel tag
Cool, those both helped alot. Unfortunately, they have lead me to
realize another major flaw in my plan. Of course the wicket panel is
destroying the content in the template. In most cases that is a
feature, but in this case the point is for the control to act as a
wrapper around other content (both static AND wicket replaced). But
of course, the panel is replacing that content.
So is there a way to preserve the child content? To illustrate the
plan, I want my markup in the HTMl template to look something like:
Tab One!
Tab Two!
but the rendered HTML would add a hidden input, and some javascript,
but would otherwise preserve the rest of it's content, including any
wicket:id marked tags. It would go to the browser as something like:
Tab One!
Tab Two!
/* some javascript not worth repeating here */
I suppose I *might* be able to have the drawTabsHere div NOT
encapsulate the tab1 and tab2 div's. That is the direction I will
start moving, but is there a way to achieve the above ideal? Since
tab1 and 2 are children of the drawTabsHere node, it would be better
if the markup reflected that.

Wicket Panel tag
Our app will be using ExtJS tab controls. So to make that easier I
wrapped the ExtJS code up into a Wicket Panel to hide the complexity
of working with ExtJS. The idea is that I would tell my class what
the wicket:id of the span/div was to draw the thing to, as well as
naming the N subtab id's (these are the HTML ids) so that the class
could write out the javascript code to render the tabs from the markup
already in the page. So the HTML would look like:
Tab One!
Tab Two!
And the java code would look like:
add(new MyTabPanel("drawTabsHere", "tab1", "tab2"));
The premise is REALLY close to working. Here's my problems:
1) The wicket:id="" attribute on the div won't copy the id into the
markup. I must repeat it in the template . I tried adding the id
via an Attribute Modifier like so:
add(new AttributeModifier("id", new Model(renderToID)));
But it ignores me. I'd rather not force my developers to repeat the
id. How can I accomplish that?
2) More importantly, the rendering of the tabs is malfunctioning. I
believe that it is because the panel actually DRAWS the
tag around the subtab div's and thus screws up ExtJS. I didn't
realize that panels wrote the wicket tags out to the browser until i
hit this. I'd always assumed that "wicket:" tags were for the
server's use, and were not rendered. How can I suppress this so that
the DOM hierarchy is right for my use?
I do have a hidden input tag in the wicket:panel in order to preserve
the selected tab so that we preserve it between submits. I tried
removing it and it did not help, but cannot remove the wicket:panel
without Wicket throwing an exception.

Combo Box (help!)
This is a second asking, so sorry if I am being impatient, but I was
hoping to see a response to this.
I've got a combo box with the list in a List of string arrays (code
and decode). The bean has the currently selected code. I created a
DropDownChoice with a custom ChoceRenderer as below. The CR interface
is invoked for both the acquisition of the bean value and for each row
of the list, which is why the below code checks the type of object
coming in.
This works great when displaying, but when the value comes back to the
server, it is loaded back into the bean as
"[Ljava.lang.String;@3c6f3c6f". It looks like the Object.toString().
What am I doing wrong here?
DropDownChoice ddc = new DropDownChoice(id, new PropertyModel(bean,
id), listOfStringArrays, new IChoiceRenderer(){
@Override
public Object getDisplayValue(Object array) {
if(array instanceof String)
return (String) array;
else if(array.getClass().isArray()){
String[] result = (String[]) array;
return result[1];
}
else
throw new RuntimeException("Huh?");
}
@Override
public String getIdValue(Object array, int arg1) {
if(array instanceof String)
return (String) array;
else if(array.getClass().isArray())
{
String[] result = (String[]) array;
return result[0];
}

Panel without HTML
I don't have this situation right now, it's mostly curiosity, but I've had these requirements at times in the past. If I had a panel whose appearance was highly dynamic, say perhaps because it was driven by some personalization or data, can a Wicket panel add components that don't have a corresponding tag in HTML? So I would just have a tag for where the wicket panel renders, but the panel might consist of an unknown combination of other controls so that I could not have a static HTML template for it. How might I handle that in wicket? Brian Mulholland - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Simple TextField Override and A SubmitLink Question
Thanks for the response. I have two thoughts.
1) So you would say that expected Wicket best practice would be what?
My control is effectively a TextField. Would I extend
AbstractTextComponent (which I see has almost every property TextField
has) and then add() a TextField and a Label to it, and simple
oscillate their visibility based on my enabled flag? I could see
doing that for this situation.
2) However, I wasn't just curious about this situation, but also the
more general principle. Perhaps there is a better way to skin this
particular cat, but writing components (new or extended from existing
ones) that modify the HTML rendered seems like a sensible and powerful
use of Wicket's component architecture (indeed, it seems to me to be
Wicket's primary advantage). But if the onRender has implicit
undocumented rules, then I will bump into them later on when I am
writing my HTML.
For example, let's say I wanted to write a rich DHTML control out of
divs and spans that effectively is a specialized Grid (or whatever).
I would want to make a custom control that extends the ListView (since
we have alot of properties in common) but render the output HTML my
own custom way. I would assume that overriding the onRender would be
a big part of that, but I need to know the rules for doing so, and I
don't see where they are documented.
I would call this the equivalent of writing my own custom taglibs to
support my application's needs. Wicket's all-java approach has me
drooling of the potential for re-usable bits, but I need to feel
confident that the framework will support that before I sell the
notion to my teammates.

Simple TextField Override and A SubmitLink Question
I am a Wicket n00b. Just learning and writing a demo app to evaluate
Wicket vs a few other MVC solutions which are having demos written by
other developers in the group. I am having two issues.
Issue 1 involves me trying to write a custom TextField to demo the
idea of overriding a control and outputting custom HTML to support it.
The plan was to override the onRender and write out plain text when
the control is disabled instead of writing out a textbox with the
enabled flag set to false (which is the default behavior).
So I wrote a TextField with the following onRender:
@Override
public void onRender(MarkupStream stream)
{
if(this.isEnabled())
super.onRender(stream);
else
{
getResponse().write(getModelValue());
this.renderNext(stream);
}
}
I read about the renderNext on nabble, which resolved one exception I
got, but now it throws exceptions saying that it cannot find the
component as if I declared it in html, but did not add it to the
hierarchy. I know the code outside this render is fine because if I
change the code to keep the super.onRender() call, but merely surround
the super with a span tag with display:none, it works fine.
But I really wanted this style to work as a proof of concept of
overriding the onRender to output whatever HTML we need. Customizing
components to put our custom HTML seems to be Wicket's greatest
feature. But clearly there is some aspect of the onRender contract
that I am missing. The super must be taking care of something that I
am not aware that I am required to take care of. Any Ideas?
Issue 2: Same page. When the page is in readOnly mode, I set a
readOnly flag, set all my controls to disabled, and change what links
show. I am using SubmitLinks. When the page loads the first time one
set of actions is enabled (such as a Modify link) and upon hitting
modify, I set the controls to enabled, and display Save and Cancel
links while hiding the others. But upon getting to the modifiable
mode, none of the SubmitLinks work. I even tried showing all the
links all the time and once I have run a request through the app, none
of the links respond anymore.
However, I found that if I eliminate the code that iterates through my
controls, the links work. I wrote a simple setEnabled method that
uses the IVisitor interface like so:
@Override
public Object component(Component comp)
{
MyBasePage page = (MyBasePage) comp.getPage();
if(FormComponent.class.isAssignableFrom(comp.getClass()))
comp.setEnabled(!page.isReadOnly());
return IVisitor.CONTINUE_TRAVERSAL;
}
Thus each page will inherit from MyBasePage and just change the
readOnly flag. I don't want to disable every Component since I want
some of the links and other things to work. I may have to make this
method smarter in the future, but for now this is pretty close to what
I want...except for the small detail of not actually working. I know
that the links are never getting disabled by this code because I
debugged through it, and also echoed out the isVisible and isEnabled
after the fact. However, when I don't do this, my links refuse to
respond on the 2nd request. Further, the request they stop working on
is when I am ENABLING the controls.
So why if the links are not disabled, might they not be responding
when I click on them. The onSubmit() method of the form never gets
control. I've tried to provide all the information I know. Anyone
have ideas? Even if you don't know what might be wrong, if you can
suggest an avenue of investigation that would be helpful.
Also, what resources do you suggest for a Wicket noob? I've been
looking at the javadoc and the Wicket wiki and the examples on the
apache site. But they all seem fairly light. The javadoc often has
insufficient detail (see the onRender issue), the wiki has large
important sections simply labelled "TODO", and the examples seem
mostly slanted toward things that don't really show off the good
stuff. Are there other good resources that I should be using?
