custom icons on LinkTree nodes?
Hi, I'm using a LinkTree to display a tree-structure with links in a sidebar. What do I have to do to get it to display custom icons (on a per node-basis) in the tree? Help would be very much appreciated. / Wille -- View this message in context: http://www.nabble.com/custom-icons-on-LinkTree-nodes--tf4560283.html#a13014231 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: custom icons on LinkTree nodes?
If you are referring to open/close images
Try this in ur LinkTree class impl:
protected Component newNodeComponent(String id, IModel model)
{
return new LinkIconPanel(id, model, LinkTree.this)
{
private static final long serialVersionUID = 1L;
protected void onNodeLinkClicked(TreeNode node,
BaseTree tree,
AjaxRequestTarget target)
{
super.onNodeLinkClicked(node, tree, target);
LinkTree.this.onNodeLinkClicked(node, tree,
target);
}
@Override
protected ResourceReference
getResourceFolderOpen(TreeNode node) {
// return ur own resource ref impl for ur
custom open image
// On per node basis, just use the above
node ref to do ur stuff
}
protected ResourceReference
getResourceFolderClosed(TreeNode node)
{
// return ur own resource ref impl for ur
custom close image
}
protected ResourceReference
getResourceItemLeaf(TreeNode node)
{
// return ur own resource ref impl for ur
custom leaf image
}
};
}

Re: Session size is constantly increasing on setResponsePage(getPage())
are you talking about 1.2 or 1.3?
in 1.2 a session could grow a little bit because we have there max 7 pages
that all also can contain some version info.
But as you said when you do setResponsePage(Page.class) everything drops to
normal
that means that you have to use 1.3 because then the newly created page
replaces the old one in the session memory.
But if you set in the link click the same page that the link is on
(setResponsePage(getPage()). You see a grow?
That seems a bit strange. need to check that out then.

Hi there,
we're developing a rather straight forward application with wicket and I
am
wondering if it is ok to call setResponsePage(getPage()) inside the
onClick() method of a Link? Because the session size is constantly
increasing, here's my example:
Application class:
public class TestApplication extends WebApplication {
public TestApplication() {
super();
}
@Override
public Class getHomePage() {
return TestPage.class;
}
@Override
protected void init() {
super.init();
mountBookmarkablePage(/home, getHomePage());
}
}
Page class:
public class TestPage extends WebPage {
public TestPage() {
super();
setVersioned(false);
add(new TestLink(testLink));
}
@Override
protected void onBeforeRender() {
super.onBeforeRender();
System.err.println(getSession().getSizeInBytes());
}
}
Link class:
public class TestLink extends Link {
public TestLink(String id) {
super(id);
}
@Override
public void onClick() {
setResponsePage(getPage());
}
}
Everytime the Link is clicked the session size increases a bit (it may be
tiny in this test application, it's nevertheless increasing constantly).
Whenever (this clue comes from testing our real application) a new page is
constructed (be it via setResponsePage(Page.class) or via url) the session
size falls back to normal. When an older instance (via back button or
link)
is used, the session is as big as before.
I also noticed that when using TabbedPanel (from wicket-extensions) each
tab
change (out of the box) increases the session size much more.
All our models are LoadableDetachableModels, so our model objects are all
transient and should never be stored in the session. Of course we use here
and there a new PropertyModel() and other wrapper models, but only in
constructors.
Any suggestion what we could do about it? In the real application the
increment is about 2-3Kb per click, which will become a problem since the
application is click-intensive and collaborative (many session at the same
time).
Thanks in advance,
Martin

Re: Google Maps API
hmm.. how do you deploy? To get a first glimpse, a: mvn jetty:run should get the jetty server running and the examples should be visible at: http://localhost:8080/wicket-contrib-gmap2-examples/ If you want to start it from within Eclipse using the Start class a: mvn eclipse:clean eclipse:eclipse cleanly rebuilding eclipses project and classpath files might help. Also a eclipse classpath variable has to be set up, but eclipse warning will guide you to that. Basically the exception says that that the classes providing the logging implementation can't be found, Log4J, in this case. Could it be that you are trying to get it started in a geronimo server? I'm not quite familiar with setting those up, but the Log4J jar has to be present on the runtime classpath, WEB-INF/lib if you go by the standards, but maybe your container has configuration files for that. Martin Ballist1c schrieb: Ive downloaded and compiled the Gmap2 and examples, however, the examples don't seem to deploy... there seems to be some low level issue.

Re: pass information through ajax without form
For a similar case, I override (in MyBehavior)
@Override

And you need to override (server or client side) the callbackUrl to add
parameter.

i can add custom js to the wicket ajax javascript, but how can I pass the

Re: pass information through ajax without form
Currently I have no simple example :-(
In my case (wicketstuff-jquery), I've got a link that call a javascript
function generated (with a template on server side).
In this function :
var wcall = wicketAjaxGet('${callbackUrl}' +
DnDSortableBehavior.asQueryString(), function(){}, function(){});
And the method DnDSortableBehavior.asQueryString() is in charge of formated
collected state, params,...
var DnDSortableBehavior = {
...
asQueryString : function() {
return 'itemId=' + this.itemId + 'srcContainerId=' + this.srcContainerId +
'srcPosition=' + this.srcPosition + 'destContainerId='+ this.destContainerId +
'destPosition=' + this.destPosition;
}
};
In my case I use jquery to retrieve states, values.
If I've got time this evening, I'll try to create a sample.
Which type of information do you want to send back to server ?

Wicket Ajax Debug window - font color
Hi,
The Wicket Ajax Debug (WAD) window has a background color set to white
but the font color is not set (in wicket-ajax-debug.js) - it uses the
base page defaults. So when I have in css for my page setting like
this: body {color: #FF;} the text in WAD is not visible.
Maybe you should add somewhere in wicket-ajax-debug.js setting like
this: color: black;
PS. I'm using Wicket 1.3.0-beta3.
Best regards,
Daniel

Re: pass information through ajax without form
my case is:
there is a javascript variable (let say var STATE;) that will be updated
througout the client side javascript event
there is a link (for example) that I want to use to pass the STATE through
ajax to server.
in your codes, does client side javascript method
DnDSortableBehavior.asQueryString() generate the query string and append
to the wicketAjaxGet? and you parse the parameters in the server side?
I think you have already given me good hints and I will continue work on
that, thanks very much

Whenever (this clue comes from testing our real application) a new page

All our models are LoadableDetachableModels, so our model objects are
all
transient and should never be stored in the session. Of course we use
here
and there a new PropertyModel() and other wrapper models, but only in
constructors.
Any suggestion what we could do about it? In the real application the
increment is about 2-3Kb per click, which will become a problem since

Adding a Link for a Whole ListItem
With a ListView is there a way to actually create a Link component that encompasses the whole ListItem, such that when you click anywhere on a row the onClick event is fired? I know you can do this with Ajax support, but I'm curious if you can do this using the traditional way, i.e., with a full page refresh. I don't want to add a click here button to my row. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Adding a Link for a Whole ListItem
Yes you can, The trick is to extend ListItem and have it implement ILinkListener you can then add the onclick behavior through an attributemodifier or override oncomponenttag. To prevent having to make a subclass per page you should make the onLinkClicked method in your listitem redirect to a method in your listview. I could show you our code but it is cluttered with non relevant code, and the above really says it all.

CompoundPropertyModel stops working when form validation fails.
Hi all,
thanks for your time and for keeping up this precious users' list.
I have a page with a page-global currentRecommendation variable. The
instance of this variable is updated by selecting one of the entries
of a ListChoice; basically, the ListChoice deals with a list of
recommendations instances and sets currentRecommendation to the
one selected by the user.
When a recommendation is selected, its data are loaded and displayed
in a recommendationForm (contained in the same page) defined like
this:
recommendationForm = new Form(recommendationForm);
The form contains a custom recommendationPanel which is linked to the
currentRecommendation instance by a CompoundPropertyModel built on
an AbstractReadOnlyModel, just like this:
IModel recommendationModel = new AbstractReadOnlyModel() {
@Override
public Object getObject(Component component) {
return currentRecommendation;
}
};
recommendationPanel = new CustomPanel(recommendationPanel, new
CompoundPropertyModel(recommendationModel));
The problem is that when the form is submitted and validation *fails*,
the CompoundPropertyModel of the recommendationPanel seems to
disconnect from the currentRecommendation instance, because clicking
on a different entry of the ListChoice mentioned above still refreshes
the form but doesn't update the data contained in it anymore.
In other words, the underlying currentRecommendation instance keeps
changing correctly on ListChoice selection change (and the
AbstractReadOnlyModel correctly picks up the selected instance), but
the form (i.e. the panel contained in it) keeps displaying the
instance that failed validation and doesn't show the newly selected
recommendation instance anymore.
The whole thing happens only when form validation fails.
What am I missing?
Thanks a lot for your help,

Re: Graceful handling of ajax after session expiration
Thanks for the response! I'm not sure if this solves my problem though, or if I understand this correctly. Even if I use HybridUrlCodingStrategy to mount the page, I will still get redirected to a Session Expired page if I try to use any ajax-enabled component. A second problem emerges when I get redirected to the Session Expired page, hit the back button, and attempt to invoke the ajax-enabled component again. This time Wicket thinks I'm sending the ajax request to the Session Expired page and redirects me to a plain old error page with a stack trace. It'd be nice to be able to register Wicket ajax components in some state that persists beyond a single user's session. Martijn Dashorst wrote: 1.3 has a new URL encoding strategy that would make this somehow possible: iirc it is the hybrid url coding strategy, and is for instance used at http://thoof.com The url becomes bookmarkable, and has the page nr and version number encoded in the url, but wicket will use the bookmarkable part when there is not session.

Re: CompoundPropertyModel stops working when form validation fails.
Hi,
if I understand correctly, the page variable and the panel model should
always point to the same thing. I suggest you give your page a model with
currentRecommendation as model object. Then construct your panel with the
same model instance as the page (or wrap it with an IChainingModel) and get
rid of the page wide variable. The form's onSubmit() would be like:
selectedValue = obtainSelectedValue();
getPage().getModel().setObject(selectedValue);
setResponsePage(getPage());
so setting the page's model object to the choice the user selected, and only
setting it if validation succeeds. This is what we do in a similar case, we
got one listChoice that controls the whole page and so a lot of components.
hope that helps,
Martin

Getting started with Hibernate and Wicket
I'm trying to learn both Hibernate and Wicket at the same time, and I could use a couple of pointers... I have managed to take the Wicket 'signin' example and added a tiny Hibernate database which I can access to extract a 'User' object to validate the user's name and password. That works fine... But now I would like to be able to pull a list of objects (Users) out of the database and display them in a table on a new page (with columns like 'userName, 'emailAddr', 'Role' etc. etc.) I think I can get the list of data from the database using Hibernate (although I'm not sure the best way to manage a table if it has thousands of rows, which mine will eventually have...) But I'm not sure how to set up the Wicket page to display that data. Can someone point me at some simple table examples that would do that?? thanks very much, nbc - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

CheckBox is misbehaving...
NOTE: I'm stuck at Wicket 1.2.4 and cannot upgrade yet.
I've got a very simple form with an input class that looks like this:
public class PaymentInfoInput implements Serializable
{
private Boolean optedForNewsletter;
.
public Boolean isOptedForNewsletter()
{
return this.optedForNewsletter;
}
public void setOptedForNewsletter(Boolean optedForNewsletter)
{
this.optedForNewsletter = optedForNewsletter;
}
}
When the page loads I load a boolean value into my CheckBox from an entity,
like so:
//model for checkbox value
IModel checkedModel = new
Model(customer.isOptedForNewsletter());
//newsletter opt-in checkbox
form.add(new CheckBox(optedForNewsletter, checkedModel));
...I've walked through this portion in the debugger, it loads the correct
value.
Now, when I submit the form, regardless of whether or not the CheckBox is
checked, the value is null:
//create form
final Form form = new Form(paymentInfoForm, new
CompoundPropertyModel(new PaymentInfoInput()));
...
//submit button
form.add(new Button(completeOrderButton)
{
public void onSubmit()
{
try
{
//get form input
PaymentInfoInput input =
(PaymentInfoInput)form.getModelObject();
Boolean opted =
input.isOptedForNewsletter(); //WHY IS THIS NULL?
}
catch (Exception exp)
{
LogProxy.saveEntry(exp);
}
}
});
...in the HTML:
input type=checkbox wicket:id=optedForNewsletter value=true /
...what's up with that? I must be missing something painfully simple.
Thanks!

Re: CompoundPropertyModel stops working when form validation fails.
Ok, now I undestand better. So if the model of your page is complex, just put the complex data in a custom model object and then use page.setModel(new Model(complexObject)). Just move the get/set of your variable into the model object. In the form on submit then do getPage().getModel().getObject().setCurrentRecommendation(selectedValue). And the panel would be new CustomPanel(customPanel, new PropertyModel(getPage().getModel(), currentRecommendation); As for refreshing, just replace setResponsePage(getPage()) with ajaxRequestTarget.addComponent(customPanel); or whatever you'd like to be updated. The thing is: it's always better to rely on wicket for state handling and variable updating. So if two components refer to the same thing, make sure your model object is the same for both (or a property of the model object). This keeps your data where it belongs (to the model of MVC) and frees you from the hassle to deal with update events. As a last resort, you could put the currentRecommendation to the session, the brutal php approach ;) Another thought... The form works until the first time validation failes. Check if subsequents submits go through onSubmit(). bw, Martin Fabio Fioretti wrote: On 10/3/07, Martin-2 [EMAIL PROTECTED] wrote: Hi, Hi, thanks for the quick reply. if I understand correctly, the page variable and the panel model should always point to the same thing. Right. I suggest you give your page a model with currentRecommendation as model object. Then construct your panel with the same model instance as the page (or wrap it with an IChainingModel) and get rid of the page wide variable. I can't do that because my page is rather complex and it deals with at least two different kinds of objects. That's why I choose to have the currentRecommendation page variable instead, and a panel inside the related form that deals with the variable through the CompoundPropertyModel.

Re: CheckBox is misbehaving...
you are not tying your checkbox's model to the form's model object so it
saves into its own model..
as you can see here:
IModel checkedModel = new Model(customer.isOptedForNewsletter());
form.add(new CheckBox(optedForNewsletter, checkedModel));
you are giving it its own model...
so in your onsubmit you have to call checkbox.getmodelobject() to retrieve
the value, or give it a model that is properly tied to the form's model
object via a propertymodel or something else

Missing resource parameters for an Image using a ResourceReference
I am using a ResourceReference to access a SharedResource for an Image. I am
also passing parameters via a ValueMap to obtain the correct image.
However, when I look at my URL, the parameters are missing.
I traced it to Image.onComponentTag()
code
final ResourceReference resourceReference =
getImageResourceReference();
if (resourceReference != null)
{
localizedImageResource.setResourceReference(resourceReference);
}
/code
which calls localizedImageResource.setResourceReference( resourceReference,
null ) and therefore clears the parameters.
So either I am doing this all wrong or this is a bug. Can someone point the
way for me?
Thanks
- Doug
BTW...in Image constructor, I am doing the following:
code
public HoleImage( String id, Long golfCourseId, int holeNo ) {
super( id );
ResourceReference ref = new
ResourceReference(MyOwnGolfApplication.class,
holeOverviewImage);
ValueMap map = new ValueMap();
map.add( golfCourseId, golfCourseId.toString() );
map.add( holeNumber, String.valueOf( holeNo ));
setImageResourceReference( ref, map );
}
/code

Re: Missing resource parameters for an Image using a ResourceReference
BTW...if I change LocaledImageResource.setResourceReference(
ResourceReference ref ) to the following:
public final void setResourceReference(final ResourceReference
resourceReference)
{
setResourceReference(resourceReference, resourceParameters);
}
Everything works as expected.
Another possible solution would be to expose the parameters in
LocalizedResourceReference (get/set)Parameters. Then the change could be
limited to Image.onComponentTag()
final ResourceReference resourceReference =
getImageResourceReference();
if (resourceReference != null)
{
localizedImageResource.setResourceReference(resourceReference,
localizedImageResource.getParameters());
}
BTW...I filed a bug report for this issue

Custom label for number and currency formatting?
Does such a thing exist? I thought it did, but can't find it now. Basically, I want a Label that allows me to format floats/doubles as currency. I don't need i18n built in (for different currencies, etc.), just take double x=8.3 and output $8.30. Any pointers are appreciated! Thanks.

Re: Google Maps API
Ah that might explain it... ive attempted to deploy it in the current Netbeans IDE im using with the crappy tomcat integrated server (v5.5 or osmething i think) My main project is destined to run on a base tomcat server at the moment, and as a team we are not considering adding any other containers or extensions to tomcat just yet... :( so whatever googlemap implementation i use.. or googmap implementation i create, will need to run on tomcat. :S... martinf wrote: hmm.. how do you deploy? To get a first glimpse, a: mvn jetty:run should get the jetty server running and the examples should be visible at: http://localhost:8080/wicket-contrib-gmap2-examples/ If you want to start it from within Eclipse using the Start class a: mvn eclipse:clean eclipse:eclipse cleanly rebuilding eclipses project and classpath files might help. Also a eclipse classpath variable has to be set up, but eclipse warning will guide you to that. Basically the exception says that that the classes providing the logging implementation can't be found, Log4J, in this case. Could it be that you are trying to get it started in a geronimo server? I'm not quite familiar with setting those up, but the Log4J jar has to be present on the runtime classpath, WEB-INF/lib if you go by the standards, but maybe your container has configuration files for that.

Re: webpage instance scope?
1.say I go to an app at localhost/MyApp/app 2.App's home page is HomePage.class; its' constructor executes 3.I do browser reload, HomePage's contructor is executed again (so I'm getting a new object and not one costructed in #2) Your home page is a bookmarkable page (and are thus not session relative), and bookmarkable pages are constructed for every request. Older instances will by default be pushed to second level cache. If pages are stateless, they are discarded right away and will not be part of the session store's history (we don't need that because the as state doesn't matter for these pages, we can construct them from scratch on every request, even for the back button). How can I get Wicket to reuse object from #2 in step 3? You typically don't unless you have a very specific reason for it. But if you want, you can implement a custom page factory for instance. Though that's probably pre-mature optimization. If you navigate between pages, you can reuse instances by passing references to those pages. A typical use for that is when you have a list and a detail screen and from that detail screen you want to navigate 'back'. Again, if the only reason you want to do such things is efficiency, you're probably prematurely optimizing.

Re: webpage instance scope?
Scoping depends. RequestCycles and stateless pages are per request, Sessions are per session, Application is per Wicket filter. How pages are scoped basically depends on the session store you use, and whether they are reachable by the back button. By default, the current page is stored in the session, so that call backs (form submits, non-bookmarkable links, etc) can immediately be handled on the instance. New pages push older ones to 'second level cache', which is typically a file in a temp dir or a data store shared in a cluster (if you want to support fail over for the back button). As long as pages are in that second level store, they are reachable. Instead of using the Servlet API's scopes, it is probably more useful to think about reach-ability of your pages/ components, just like you would do with normal server-side/ desktop Java programming. Pages are reachable as long as the session stores can find them (and that is only really relevant for back button support), and components are reachable as long as you keep passing them on/ can be reached from the current page. Does that make sense?

Re: Custom label for number and currency formatting?
Do this
double x= 8.3;
Label dbl = new Label(dbllbl,+x){
@Override
protected void onComponentTagBody(final MarkupStream
markupStream, final
ComponentTag openTag)
{
Object val =
getConverter().convert(getModelObjectAsString(),
Double.class);
final NumberFormat nf =
NumberFormat.getCurrencyInstance();
String newval = nf.format(val);
replaceComponentTagBody(markupStream, openTag,
newval);
}
};
If you want to vary the locale on some cond, just use the method
getCurrencyInstance(Locale inLocale) in NumberFormat class
