No, not true. You /can/ do setResponsePage(new ItemListPage(...)), /and/ make it bookmarkable. The trick is to call setRedirect(true) together with the call to setResponsePage.

Indeed. I would very welcome this capability. Regards, Erik. David Leangen wrote: once again, i dont see what this offers over the hybrid strategy. Maybe you can correct me if I'm wrong here... The hybrid stategy is only applied when the target is an IBookmarkablePageRequestTarget. So, for normal bookmarkable pages, there is no problem, like you say. The issue only arises when a page is mounted, but is used in a stateful way (for example it has a form or something). In that case, the target becomes an IListenerInterfaceRequestTarget. When this is the case, the hybrid strategy is not used.

Re: More on wicket url stratergy
Yes, I am pretty sure I did this about a month ago. The funny thing is that we did it this way because this way flash (component error messages) are preserved. We wanted to show a succes message on the page we forwarded to. ... looking up the code now... Yep, correct. Though we did not call setRedirect(true) as the code runs from a Form#onSubmit callback which always redirects anyway. Regards, Erik.

Subject: Home page accepting IndexedParamUrlCodingStrategy
How do I go about making my HomePage accept index parameters? I want
a home page that will accept URLs like:
localhost:8080/us/ca/sacramento
Instead of having a mount point first, for example /home:
localhost:8080/home/us/ca/sacramento
I've tried this in my app:
getHomePage() {
return HomePage.class;
}
init() {
mount(new IndexedParamUrlCodingStrategy(/, HomePage.class));
}
This returns in a 404 error for the home page (localhost:8080/). I
also tried with instead of / as the mount point, but the same
problem.
If I use this with the /home mount point, everything works perfectly:
mount(new IndexedParamUrlCodingStrategy(/home, HomePage.class));
FYI... I get the PageParameters in HomePage like this (which is
working fine);
setCountry(pageParams.getString(0,null));
setState(pageParams.getString(1,null));
setCity(pageParams.getString(2,null));
Any suggestions?
Thanks,

Re: Home page accepting IndexedParamUrlCodingStrategy
There are 2 problems in this code:
1. mount specifies that the mount point is given without a leading '/'
(even though it tolerates it)
2. you can not call mount with , it will throw an exception (and
therefore not with / either)
Actually, it would be nice if you could do the latter. As long as the
target class is the same as the home page class, I should perhaps not be
prohibited.
I'd say: open a jira issue and attach a patch :)

Erik.

not having indexed urls for '/' makes sense for me

Re: How to access properties files outside of Wicket components?
Look carefully. Your code sample does:

Which loads it from the package MyComponent is in.

Re: Why is it illegal to update hierarchy in onAfterRender?
Hello Johan et all, Ok, I see the problem. But let me then propose a change to the exception text. Something like can not change hierarchy after render phase has started. I'll create a Jira issue if you like. But why? Well, its one of the things I tried in a long list of attempts to do custom Ajax things. More experienced Wicketeers can probably point me in more productive directions. I have this set up where custom javascript uses the result of an Ajax response and places it in a modal window (or on other places in the page). Why? Well, our html/javascript designer refuses to use the wicket ajax libraries but writes everything himself. The only thing he trusts is jquery. So I worked around this by creating my own Ajax behaviors (which is pretty easy as you can easily get the URL that should be called from the client). I reused AjaxRequestTarget to generate the response. Now AjaxRequestTarget wants the component that is rendered to be a part of the current page. I therefore add the panel to be rendered to the page, even if it is not really used like that in the client code (as with the modal window). Therefore, at some moment it needs to be removed again as well. For removal I have 2 cases: -1- the modal window contains a form, the form might be submitted, so the server gets feedback. -2- the modal window only displays some information or the form is not submitted, the server gets no feedback on the close of the modal window For case -2- (in my earlier attempts) I tried to remove the component in onAfterRender. After realizing that this doesn't work, I did it in the onBeforeRender when some flag was set (accepting that it can be stored in the session for some time). But I only just realize that this case could be solved a lot better by using a Page instead of a Panel to deliver the content for the modal window. In case -1- however, I need to update the page that initiated the modal window. As we're not allowed to keep references between pages (because of the disk store's serialization tricks), I add the modal window panel to the page (with the form on it), and remove it again within the ajax-submit of the form. In the same onSubmit I update some components on the page, re-render them (again using AjaxRequestTarget) and pass them back to the client. This works, but when the form is not submitted, the modal window panel is never removed from the page. After a couple of such closes, the response time of the page easily explodes to half a minute. Ideally I would use a Page for the model window's content as well. However, I see no way to get a reference to the page it was opened from. Can anyone shine a little light on this? Is it possible to get that page reference? How does Wicket's modal window do this? Regards, Erik. Johan Compagner wrote: Why do you want to do that? The problem is if you affect the page then the page version is affected. So all what is rendered now isnt really the state wat the page has. Thats why you get that exception when rendering has started.

Re the feature for determining which category to create a logger for, see the documentation for Exception.getStackTrace. There is no guarantee that valid info about the callstack is available. So this code will work fine under unit testing, then may start emitting messages to the wrong categories when run in a high-performance environment. That will be fun to debug... Re the printf-style formatting: log.debug(format str, arg0, arg1, arg2); is exactly equivalent to: push format str onto stack tmp = new Object[3]; tmp[0] = arg0; tmp[1] = arg1; tmp[2] = arg2; push tmp onto stack invoke log.debug (and of course garbage-collect the tmp object later..) So in practice, for good performance you need if (log.isDebugEnabled()) around each call anyway. In which case, the printf-style stuff gives no performance benefits at all; if something is going to be logged then the formatting is nowhere near the bottleneck step. The SLF4J fake-varargs approach, where the api allows 0,1 or 2 params is slightly better, as it avoids the new Object[] call. But for best performance, isDebugEnabled should be used anyway.

An alternative is to replace the getParameterMap() method in ServletWebRequest
like this:
public Map getParameterMap()
{
// Lazy-init parameter map. Only make one copy. It's more
efficient, and
// we can add stuff to it (which the BookmarkablePage stuff
does).
if (parameterMap == null)
{
parameterMap = new
HashMap(httpServletRequest.getParameterMap());
// Replace single value parameter arrays with a single string.
for (Iterator i = parameterMap.keySet().iterator(); i.hasNext(); )
{
Object key = i.next();
Object value = parameterMap.get(key);
if ((value instanceof String[]) ((String[]) value).length ==
1)
{
parameterMap.put(key, ((String[]) value)[0]);
}
}
}
// return a mutable copy
return parameterMap;

Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.3.2
Reporter: Michael Grinner
Attachments: 1484_patch.txt
MixedParamUrlCodingStrategy has a bug in
MixedParamUrlCodingStrategy
appendParameters
if (!parameterNamesToAdd.isEmpty())
{
boolean first = true;
final Iterator iterator;
if (UnitTestSettings.getSortUrlParameters())
{
iterator = new
TreeSet(parameterNamesToAdd).iterator();
}
else
{
iterator = parameterNamesToAdd.iterator();
}
while (iterator.hasNext())
{
url.append(first ? '?' : '');
String parameterName = (String)iterator.next();
@@@ String value = (String)parameters.get(parameterName);
url.append(urlEncode(parameterName)).append(=).append(urlEncode(value));
first = false;
}
}
where value should be a String[] not a String.
like in AbstractRequestTargetUrlCodingStrategy
appendParameters
String[] values = (String[])value;
for (int i = 0; i values.length; i++)
{
appendValue(url, entry.getKey().toString(), values[i]);
}
it works ok after patching MixedParamUrlCodingStrategy to
if (!parameterNamesToAdd.isEmpty()) {
boolean first = true;
final Iterator iterator;
if (UnitTestSettings.getSortUrlParameters()) {
iterator = new TreeSet(parameterNamesToAdd).iterator();
} else {
iterator = parameterNamesToAdd.iterator();
}
while (iterator.hasNext()) {
url.append(first ? '?' : '');
String parameterName = (String) iterator.next();
Object value = parameters.get(parameterName);
if (value != null) {
if (value instanceof String[]) {
String[] values = (String[]) value;
for (String element : values) {
url.append(this.urlEncode(parameterName)).append(=).append(this.urlEncode(element));

Re: Removing the jsessionid for SEO
Hi Rüdiger, I would be very interested in the code. If you can not find a suitable repository, could you just do something simple like linking to a zip from a blog post? Regards, Erik. Rüdiger Schulz wrote: Hello everybody, I just want to add my 2 cents to this discussion. At IndyPhone we too wanted to get rid of jesessionid-URLs in google's index. Yeah, it would be nice if the google bot would be as clever as the one from yahoo, and just remove them himself. But he doesn't. So I implemented a Servlet-Filter which checks the user agent header for google bot, and skips the url rewriting just for those clients. As this will generate lots of new sessions, the filter invalidates the session right after the request. Also, if a crawler is doing a request containing a jsessionid (which he stored before the filter was implemented), he redirects the crawler to the same URL, just without the jsessionid parameter. That way, the index will be updated for those old URLs. Now we have almost none of those URLs in google's index. If anyone is interested in the code, I'd be willing to publish this. As it is not wicket specific, I could share it with some generic servlet tools OS project - is there something like that on apache or elsewhere? But maybe Google is smarter by now, and it is not required anymore? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: DropDownChoice getting value into the model
Hi Vitaly, That is correct. For primitive model values you need something like a map. I think the DropDownBox was more designed for complex data where the data to display is embedded in the model value itself. Anyway, how would the addition of an index argument to the display method help? Regards, Erik. Vitaly Tsaplin schreef: Hi everyone, Hi Erik, I am sorry for so late post. But am going to go back to our DropDownChoice discussion. If you suggest me to create a list of integers and use a special renderer implementation to retrieve a displayable value you should take into account that in case if we have a list of indices we can easily look up in an array or a list using an index. But if we have a list of unordered integers for example to do such a lookup we need to create a map and search this map every time we render a single option. That comes from the fact that a relationship between a value and its displayable equivalent is not obvious for a renderer. So I would ask to add an index of an options being rendered to the getDisplayValue method. Vitaly - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How can I update the repeatingview periodically
The problem is in the models of the labels. These are statically
assigned once.
fix:
protected void populateItem(Item item) {
item.setModel(new CompoundPropertyModel(item.getModel()));
ThreadInfo threadInfo=(ThreadInfo)item.getModelObject();
Label threadIdLabel=new Label(threadIdStr);
Label methodNameLabel=new Label(methodName);
Label timeStampLabel=new Label(timeStamp);
item.add(threadIdLabel);
item.add(methodNameLabel);
item.add(timeStampLabel);
}

Interesting markup question
Hi, I recently tried the following in a panel's markup: div wicket:id=menu/div add(new MenuPanel(menu)); and in MenuPanel.html: wicket:panel class=menuBar ... /wicket:panel Unfortunately the class attribute was not put in the result. It was even silently ignored! WDYT, is this desired behavior? FYI, this is my workaround: wicket:container wicket:id=menu/wicket:container add(new MenuPanel(menu)); and in MenuPanel.html: wicket:panel div class=menuBar ... /div /wicket:panel Regards, Erik. -- Erik van Oosten http://day-to-day-stuff.blogspot.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Interesting markup question
Hi Maurice, Nice, I did not think of the setRenderBody option. Thanks! Erik. -- Erik van Oosten http://day-to-day-stuff.blogspot.com/ Maurice Marrink wrote: The logic thing would be to add the class to the div: div wicket:id=menu class=menuBar/div However i can see your point of adding it to wicket:panel if you want to enforce it on all menu's. Sure would be nice if wicket could automatically transfer anything extra it finds there to the actual element, but then what would be the behavior if setRenderbodyOnly was used, they would effectively bypass your enforced css style. So imo using a div in wicket:panel to do this, optionally in combination with setRenderbodyOnly to get rid of the empty div wicket:id=menu is the best way to go if you want to force this kind of stuff.

Re: ajaxified dynamic lists as parts of bigger forms
Hi Wojciech, I am sorry, it appeared I wrote too quickly. This morning I found out that what I wrote mostly does not work. You /can/ call processInput() on any form component (if not all). This will make that particular form component puts its value in the model. But any way, the nested forms seems the way to go. I prefer the refreshing repeater as does not have the tricky model-re-use-problem. Still, ListView works fine if you know how to use it. AjaxSubmitLink is of course fine too. Personally I try to avoid components that completely depend on Javascript. Regards, Erik. Wojciech Biela wrote: Thank you Erik, You should use Buttons instead of links. Button (or AjaxFallbackButton) does submit the form. Why, should I submit using links? we've just done it using a nested form and attaching a AjaxSubmitLink to it.

You can optionally call form.validate() in the onSubmit of the button so that validation messages do not disappear. Problem is I can't call form.validate() or more importantly form.updateFormComponentModels from the link's onSubmit method because those methods are private.

Hello
This time my question is not so general.
We have a big form, part of this form there is a component which
should be a dynamic list of fields like this:
|TextField| - remove
|TextField| - remove
|TextField| - remove
|TextField| - add
if you click add another row |TextField| - remove should appear at
the bottom, it you should click remove then this row should be
removed
problem we have is that the add and remove link does not send the
form, it only sends and ajax request to add an element to the list of
components and it operates (target) on a DIV that wraps the whole
list, so afterwards it renders the list again loosing values that were
already put in
what is the preferred method to do such a thing? should the add and
remove link be a submit link with defaultFormProcessing set to false?
or maybe should we try to save values to model objects onchange in the
respective fields themselves
isn't there a way to do it in a neat fashion?
code responsible for the list component is
wrapper = new WebMarkupContainer(attributes-wrapper);
listView = new ListView(attributes, attributeValuesList) {
public void populateItem(final ListItem listItem) {
final AttributeValue attributeValue = (AttributeValue)
listItem.getModelObject();
Renderer inputRenderer =
attributeValue.getAttribute().getInputRenderer();
Component component = inputRenderer.getComponent(attributeValue);
listItem.add(component);
AjaxLink addLink = new AddLink(add-link);
AjaxLink removeLink = new RemoveLink(remove-link, listItem);
if (listItem.getIndex() (listView.getViewSize() - 1)) {
addLink.setVisible(false);
} else {
removeLink.setVisible(false);
}
listItem.add(addLink);
listItem.add(removeLink);
}
};
wrapper.setOutputMarkupId(true);
HTML is
div wicket:id=attributes-wrapper class=composit-wrapper
div wicket:id=attributes class=composit
div wicket:id=attributeAndValue
class=composit-item/div
div class=composit-links
a wicket:id=add-link+ add/a
a wicket:id=remove-link- remove/a

Re: Markup Rendering issues
Hi Jörn, -- Ids This one of the exceptions in just taking existing HTML. Our designers also use jquery and solved the problem by using classes. Something like: class=idCommentForm. For jquery it doesn't matter much, and by including id in the class name the intend is still clear. -- Wicket tags This is all time high FAQ :) Do getMarkupSettings().setStripWicketTags(true) in the init() of your application class.

Wicket generates id=commentForm4 or id=commentForm5 - I've got no idea where that number comes from. Specifying an id-attribute doesn't help, it gets overwritten. So far I was unable to select elements via jQuery using the wicket:id attribute, most likely the namespace and colon kills the attribute selector. In other words: How can I instruct Wicket to render and static id-attribute? Another, similar issue: Wicket renders stuff like wicket:child and wicket:panel into the HTML markup. While the browser ignores it, I don't know why Wicket doesn't filter out those instructional markups instead. Is that configurable? All in all, I'd like to use Wicket without making it obvious to someone reading the markup that Wicket is used to generate it. So not tags and attributes with the wicket namespace should appear in the markup - I'm not using Wickets Ajax stuff anyway. For completeness, the action attribute of my form must be modified, too. Currently the contain something like ../?wicket:interface=:1:loginForm::IFormSubmitListener::. How can I replace that, eg. mount a static URL for that form? I guess most of this is easy to resolve and I just don't know enough about Wicket, yet. Pointers or solutions are both highly appreciated.

gmap vs gmap2?

Re: gmap vs gmap2?
Thanks Martin, Ryan, I tried to run the examples of gmap2 today (no time for the code yet). Just as an experiment I compiled gmap2 against the wicket 1.3.1 release instead of the documented Wicket trunk. The examples work, so I guess it is possible to change the dependency. I am also searching for a google-map component that allows you to select an area (a rectangle) on a map. Are there existing components that do this? Regards, Erik.
