I wasn't talking about the links that are on the list (I already make those
bookmarkable). I'm talking about the links that the Navigator generates.

Most of the results tell you to get rid of the jsessionid. Granted, it doesn't seem google has specifically mentioned this either way so all these comments are rumors. But the fact of the matter is Google *DOES* index your urls with the jessionid still in it. You'd think they'd be smart enough to remove that, right?

Most of the results tell you to get rid of the jsessionid. Granted, it doesn't seem google has specifically mentioned this either way so all these comments are rumors. But the fact of the matter is Google *DOES* index your urls with the jessionid still in it. You'd think they'd be smart enough to remove that, right? If they can't get that much right, I wouldn't want to make any other assumptions about their abilities on similar matters. > > -- > Buy Wicket in Action: http://manning.com/dashorst > Apache Wicket 1.3.2 is released > Get it now: http://www.apache.org/dyn/closer.cgi/wicket/1.3.2 > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: java.io.StreamCorruptedException: invalid type code: 29
I debugged my application and it really doesn't have a
ClassNotFoundException eaten by ObjectInputStream. I compared the flow of
two screens of my application, one that works and another that doesn't:
1) The line 298 of SecondLevelCacheSessionStore =>
getLastPage().getVersion(versionNumber) is returning the correct page,
because inside the getVersion() method, the versionManager object is null.
In this case, the screen that I'm testing works perfectly.
2) For the screen that throws the StackOverFlow and
StreamCorruptedException, for some reason the versionManager object is not
null, and it returns a null page object.
Another strange thing is that after the line 393 of Objects.java => return
ois.readObject(); => while debugging it using Eclipse, after this method
call the flow goes straight to the line 363 of AbstractPageStore.java,
without entering the finally block. So, an infinite loop starts, causing the
StackOverflow.
During the tab switch of the screen that works, the line 393 of Objects.java
is never reached, meaning that this screen was not serialized, right? This
code is only reached during a tab switch of the screen that throws
StackOverFlow exception.
What defines if a page should be serialized/deserialized? Does anyone know
what could be causing these problems?

no, you are not missing anything. you see, when you go stateless, like
what you want, then you have to recreate all the magic stuff that
makes stateful links Just Work. Without state you are back to the
servlet/mvc programming model: you have to encode the state that you
want into the link, then on the trip back decode it, recreate
something from it, and then apply that something onto the components.
This is the crapwork that wicket does for you usually.

Default selection in radio group?
I created a RadioGroup with three radios attached. For some reason the form is being drawn with the last radio pre-selected, which I don't want. How can I pre-select a default radio and also how can I set the group to nothing selected? Thanks, Michael
RE: Removing the jsessionid for SEO
Ok I did a little preliminary research on this. Right now PagingNavigator
uses PagingNavigationLink's to represent its page. This extends Link. I'm
supposed to override PagingNavigator's newPagingNavigationLink() method to
accomplish this (I think) but past that, this isn't very straightforward to
me.
Do I need to create my own BookmarkablePagingNavigationLink? When I do...
what next? I really don't know enough about bookmarkablePageLinks to do
this. Right now, all the magic happens inside PagingNavigationLink. Won't
I have to move all that logic into the WebPage that I'm passing into
BookmarkablePagingNavigationLink? This seems like a lot of work. Am I
missing something critical?

RE: Removing the jsessionid for SEO
Ok, at least I'm not missing anything. I understand the benefits it's
providing with its stateful framework. Developing a site with Wicket is
easier than with any other framework I've used. But this statefulness,
which makes websites so easy to develop, seems to be counter productive to
SEO:
GoogleBot will follow and index stateful links. Worst case scenario, these
actually become visible to google users and when they click the link it
takes them to an "invalid session" page. They think, "This site is broken"
and move on to the next link of their search result.
Another approach to solving this is to block all the stateful pages in my
robots.txt file. But how can I block these links in robots.txt since they
change per session? Is there any way to know what the url will resolve to
when googlebot tries to visit my site so I can tell it to disallow:
/?wicket:interface=:10:1::: and ?wicket:interface=:0:1::: and ...?

well, perhaps the differentiator here is that wicket is made for web
applications not web sites.

yep, you need to make sure that all stateful links are behind a login
or something similar that the bot cant get passed.

no there isnt a way, you have to use wildmasks
on the other hand it is not that difficult to develop the stateless
paging navigator, it will take a bit of work though.

Strange behaviour with autocomplete
Hi, Using the standard wicket autocomplete widget, I just noticed that I am getting some strange behaviour. When I mouseover or scroll the list via the keyboard, the entire screen jumps to the bottom. I never noticed before because there wasn't enough content to cause the page to scroll and therefore for this bug to manifest itself. Has anybody else ever dealt with this problem? Thanks!

Re: Removing the jsessionid for SEO
I've been building a community-driven hunting and fishing site in Texas for the past year and a half. Since I have converted it to Wicket from ColdFusion, our search engine rankings have gone WAY UP. That's right, we're on the first page for tons of searches. Search for "texas hunting" - we're second under only the Texas Parks and Wildlife Association. How? With Wicket? Yes - it requires a little more work. What I do is that for any link that I want Google to be able to follow, I have a subclass of Link specific to that. For instance, ViewThreadLink, which takes the ID for the link and a model (detachable) of the thread. Then I mount an IRequestTargetUrlCodingStrategy for each big category of things in my webapp. I've made several strategies that I use over and over, just giving them a different mount path and a different parameter to tell it what kind of article, etc, that it will match to. This is made easier because over 75% of the objects in our site are all similar enough that the extend from a base class that provides the basic functionality for an article / thread / etc that has a title, text, pictures, comments, the standard stuff. So, yes, it takes work. But that's okay - SEO always takes work. I also have given a lot of care to use good page titles, good semantic HTML and stuff things into the URL that don't have anything to do with locating the resource, but give the search engines a clue as to what the content is. Yes, some pages end up with a jsessionid - and I don't like it (example: http://www.google.com/search?hl=en&client=firefox-a&rls=com.ubuntu%3Aen-US%3Aofficial&q=%22south+texas+management+buck%22&btnG=Search). But, most don't because almost all of my links are bookmarkable. When the user clicks something that they can only do as a signed-in user, then it redirects them to the sign in page, they sign in, and are taken back to the page they were on. Then they can pick up, and I don't worry about bookmarkable URLs for anything that requires user-authentication (wizards to post a new listing, story, admin links, etc).

Re: Tomcat dying with Wicket 1.3.2 (Windows / JDK 1.5.0_10)
Nope - one page never holds on to another. I never even pass pages into another page or link or something as a reference. Interestingly, I DECREASED the memory the JVM could have from 1.5 GB to 1.0 GB today, and it has been stable all day (after also releasing a version using Wicket 1.3.3). That's not a definite sign - it was stable for several days after upgrading to 1.3.2 from 1.2.6 before freaking out. But I'll watch it closely. The memory creeped slowly up to the max, and has stayed there, but without the site crashing, and without any degradation of performance. Does that give anyone any ideas? I'm so exhausted, I think that I'm starting to lose my ability to think freshly about it.

Re: Writing to .properties files and make changes happen?
I call this method from inside a WebPage:
public static void setNewText(String path, String textId, String neuerText)
throws IOException {
... getting old text as StringBuffer "alt" ...
//create new String from content of .properties file
String neu = alt.replace(start, ende, neuTextTeil).toString();
File output = new File(path);
BufferedWriter out = new BufferedWriter(new
FileWriter(output));
try {
out.write(neu);
}
finally {
out.close();
}
}
That's all. The .properties file will be changed correctly, but the new
content will only take effect if I open the .properties file with an editor
and save it, but the overwriting process won't be recognized.

see ContextImage and how it generates the necessary ../../ prefix, do
the same for your javascript inside iheadercontributor.

This might not be the rigth forum to ask CSS questions and is sort of

it means that IE breaks standard compability, and due to some bug in
IE
works anyway. My prefered way of working are using firefox to develop,
checking in IE and then fix so it works in IE too..
Could you show the corresponding html?

This works fine in IE7, but for some reason only works partly in

The green background-image is removed but the text is not red, and

WebDeveloper shows the correct styles. Anybody experienced this and

IE 6 & 7 Ajax Refresh Issue
Hello, I have on a page 3 radio buttons in a group and for each radio a drop down: xDropDown1 V oDropDown2 V oDropDown3 V When the user selects a radio, the corresponding dropdown will be enabled and the other two disabled. In Firefox, this works as I need it to, but in IE, the dropdowns are not enabled/disabled as needed (either not at all - in IE6 or oddly in IE7). The funny thing is the functionality is there - i mean, although graphically they are wrong, I can change the values only for the dropdown which is enabled. And when I try to do that, all the dropdowns will be updated correctly. Any ideas what's wrong with IE and how i could update the dropdowns correctly? I use just setEnabled(true/false) and target.addComponent(...). Thanks, Cristi Manole

Re: Writing to .properties files and make changes happen?
Yes, but only if I edit the .properties file with an editor and save, then it will be recognized, if overwriting the .properties file with BufferedWriter it will not be recognized.

Re: Problems and Questions about MultiFileUploadField, UploadProgressBar
Yes, it was just a problem of Model to get back data
this.form_importerarticle = new Form("form_importerarticle") {
protected void onSubmit() {
List list = (List)model_upload.getObject();
Iterator it = list.iterator();
.
}};
this.form_importerarticle.add(new
MultiFileUploadField("fileInput",
this.model_upload, 10));
Moreover, I don't think that is possible to use MultiFileUploadField,
UploadProgressBar together, because UploadProgressBar is linked with the
simple Upload field.

Modifying inline CSS in head of document
I want to resize the height of my pages dynamically, therefore I need to
set the height of some markup elements dynamically. I don't want to use
Javascript (although I found a nice solution with jquery).
Is there a way to add a textblock like the following to the page header?
whereas the height of #leftmenu is set like this:
public abstract BasePage extends WebPage() {
...
WebClientInfo w = (WebClientInfo)getWebRequestCycle().getClientInfo();
ClientProperties cp = w.getProperties();
int minHeight = cp.getBrowserHeight();
//some imagination now
addToHeader{
addStyle("#leftmenu", "height", minHeight);
}

Re: Mount causes strange effects on my web application
OK, it seems that image paths are filtered with correct path, and thus leaves
my javascript reference as is, since I add it myself. Is there somehow I can
find out what path is correct, since I am adding javascript reference in my
java code???

Re: wicket support for page customisation at runtime
Thanks Igor. Here's an example of the usecase I am referring to. Two panels lets say (one with sports headlines and other with weather headlines) are shown one below the other by default. I want the user to be able to move their order (lets say with up and down arrows) provided in each of those panels. once the user makes the above change, I would like the system to remember these preferences and render accordingly for that user alone and differently for other users. Any thoughts on the above usecase?

In my opinion session id is a problem. Google index the same page again and
again.
About the users without cookies we can do like this:
static class Unbuffered extends WebResponse {
private static final String[] botAgents = { "onetszukaj",
"googlebot",
"appie", "architext",
"jeeves", "bjaaland", "ferret", "gulliver", "harvest",
"htdig",
"linkwalker", "lycos_", "moget", "muscatferret",
"myweb", "nomad",
"scooter",
"yahoo!\\sslurp\\schina", "slurp", "weblayers",
"antibot", "bruinbot",
"digout4u",
"echo!", "ia_archiver", "jennybot", "mercator",
"netcraft", "msnbot",
"petersnews",
"unlost_web_crawler", "voila", "webbase", "webcollage",
"cfetch",
"zyborg",
"wisenutbot", "robot", "crawl", "spider" }; /* and so
on... */
public Unbuffered(final HttpServletResponse res) {
super(res);
}
@Override
public CharSequence encodeURL(final CharSequence url) {
return isAgent() ? url : super.encodeURL(url);
}
private static boolean isAgent() {
String agent =
((WebRequest)RequestCycle.get().getRequest()).getHttpServletRequest().getHeader("User-Agent");
for(String bot : botAgents) {
if (agent.toLowerCase().indexOf(bot) != -1) {
return true;
}
}
return false;
}
}
I didn't test this code but I do similar thing in my old application in
Spring and it works.
Take care,
Artur

RE: Get informed about invalidation of a session
This has been discussed multiple times and the only reasonable solution that
I found (and just implemented) is to have a concurrent hashmap of session
ids into session objects in the custom Application class. The reason is that
on the unBind() / onDestroy the actual session object does not exist anymore
- the only thing you have is the destroyed session ID.
I needed to persist some user info on the logout.
My solution goes like this:
public class DavanoApplication extends
org.apache.wicket.protocol.http.WebApplication {
private Map activeUsersMap = new ConcurrentHashMap();
...
@Override
public void sessionDestroyed(String sessionId) {
User user = activeUsersMap.get(sessionId);
if(user != null) {
userDao.saveOrUpdate(user);
userDao.updateLastLogin(user);
activeUsersMap.remove(sessionId);
}
super.sessionDestroyed(sessionId);
}
}
I am not sure whether this is correct solution, but it did help me.

Ajax DropDownChoice and null values
Hello,
I have problem with DropDownChoice components. I have three DDC
components which loads child component choices when you change parents
value. This work, but one thing not - when I back to "Choose" choice
the Ajax request returns empty and it's because
onUpdate(AjaxRequestTarget target) is not invoked in this case.
When I remove required from parent DDC it works (nulls the chocies of
child), but I need required and show errors when submit form. I have
tried to validate component but it was validated after other
components with setRequired() set up so no show if them aren't filled
with good values.
This validating was done by such code:
_carModelDDC.add(new AbstractValidator(){
@Override
protected void onValidate(IValidatable component) {
if(((DropDownChoice)
component).getModelObject() == null){
error(component,
getString(CAR_MODEL_REQUIRED));
}
}
});
Component code which not working with null values is coded like that:
DropDownChoice _carMarkDDC = new DropDownChoice(CAR_MARK,
carMarkDAO.getAllCarMarks());
_carMarkDDC.setRequired(true);
_carMarkDDC.add(new
AjaxFormComponentUpdatingBehavior(ONCHANGE_BEHAVIOR) {
protected void onUpdate(AjaxRequestTarget target) {
carPartsModel.setCarModel(null);
if(carPartsModel.getCarMark() != null) {
CarMark carMark =
carPartsModel.getCarMark();
carModelDDC.setChoices(new
ArrayList
(carMarkDAO.getCarModels(carMark)));
carModelDDC.setEnabled(true);
} else {
carModelDDC.setChoices(Collections.EMPTY_LIST);
carModelDDC.setEnabled(false);
}
target.addComponent(carModelDDC);
}
});
Any possible clues for that?
Best regards,
Adr

Re: Customerize captcha image
Create your own captcha :) The idea of the RenderedDynamicImageResource is brilliant. You just need to implement the render (Graphics2D gfx) method. Draw there whatever you want. It's even better. No one will be able to reuse the algorithm to teach a neuronet :) On Thu, Apr 3, 2008 at 2:32 PM, wenm <[EMAIL PROTECTED]> wrote: > > Does anybody have an idea how to change the background image and font size > etc of wicket captcha image? > > > -- > View this message in context: > http://www.nabble.com/Customerize-captcha-image-tp16467447p16467447.html > Sent from the Wicket - User mailing list archive at Nabble.com. > > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
should DataView.setItemsPerPage(int items) be in IDataProvider?
when i need to get items per page in data provider i cannot unless i have data view. should this method be in data provider and not data view? the data provider is providing data and items per page is data, no?
Re: Ajax DropDownChoice and null values
AbstractValidator should work like this:
_carMarkDDC.add(new AbstractValidator(){
@Override
protected void onValidate(IValidatable validatable) {
if(validatable.getValue() == null){
error(validatable,
getString(CAR_MODEL_REQUIRED));
}
}
@Override
public boolean validateOnNullValue() {
return true;
}
});
and it works, but still no Ajax response for other components:

CheckBoxMultipleChoice with sections
I am trying to create a CheckBoxMultipleChoice subclass that supports sections. The class of items in the list will have a section name and a description. The list will guarantee that it is grouped by sections. My idea was to override getPrefix(), call a getter to get the current choice, and if the section has changed print out the new section name as part of the prefix. The problem I ran into is that the current choice is not accessible, because it is local to the onComponentTagBody method. My current solution is to copy and paste all of the code from CheckBoxMultipleChoice into my own class and hack away, but I'd like to avoid this if possible. -- Brian - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Is there an AJAX Panel in Wicket

I cannot understand why would a panel have the getparent null
Hello,
I have a HomePage where, in constructor, i add a Panel :
public HomePage(final PageParameters parameters) {
Date clientDate = getClientCalendar().getTime();
Label label = new Label("today", "Today's Status [" +
DateFormat.getDateInstance(DateFormat.SHORT).format(clientDate) + "]");
add(label);
add(reportModalWindow = createReportModalWindow());
add(countButtonsPanel = new CountButtonsPanel("countButtonsDiv",
((WebSession)getSession()).isSignedIn(), this));
add(iSmokedModalWindow = createISmokedModalWindow());
*add(todayPanel = new TodayPanel("todayPanel", new
java.sql.Date(clientDate.getTime(;
*}
in TodayPanel's constructor, i check if the user is logged, and if he is,
update an ajax table (current page)
if(user != null) {
ajaxTable.setCurrentPage(ajaxTable.getUserRow(user.getUsername(), new
Date(((HomePage)getParent()).getClientCalendar().getTimeInMillis())) /
ROWS_PER_PAGE);
}
When first running the application (no user logged in), today panel is cool.
I log in and today panel is correctly updated.
Now, when i start *another* browser page and point to the application's url,
i get a org.apache.wicket.WicketRuntimeException
because TodayPanel's getParent() returns null.
Question is: why?... i could understand it if it were consistent... meaning
it will get me null on the first login too.
I tested in Firefox tabs.
Tks in advance,
Cristi Manole
Render body only
Hi, I'm looking to do exactly what was discussed in a thread a few years ago (http://tinyurl.com/3yo43s), namely to dynamically include or exclude a group of tags. I can wrap them in a with a WebMarkupContainer, but I like to have valid HTML and really don't want the tag in the final output. The thread mentioned seems to imply that this was already committed in 2005, but I can't find it in the API. Component has public final boolean getRenderBodyOnly() which looks perfect except that it's final. Am I missing something else that allows for this?

RE: Removing the jsessionid for SEO
When Google asks to not have special treatment for their bot, they are
referring to content more than anything. Regarding the session id being
coded in the URL, see the Technical guidelines section of Google's
Webmaster Guidelines -

It specifically recommends "allow(ing) search bots to crawl your sites

Re: ModalWindow and Ajax?
this did not do the trick in my onchange:

should it be prepended or when should it be append before the onchange

If you are asking for org.apache.wicket.extensions.wizard.Wizard
it may be caused because your components are nested inside other containers
in the Wizard class so you have to go through the whole hierarchy. For
example:
"YourWizard:form:view:yourComponent"
try this code:
WicketTester wt = new WicketTester();
wt.startPage(YourPage.class);
WebMarkupContainer container = (WebMarkupContainer)
wt.getComponentFromLastRenderedPage("YourWizardStringId:form:view");
Iterator it = container.iterator();
while (it.hasNext()) {
System.out.println(it.next());
}

Displaying date as Label.
Hi All,
I need some help displaying date correctly in Label. I am using a text
field(and DatePicker) to take date input and storing it in mySQL database.
But while displying it as a "Label" I am only seeing time (i.e it always
shows 12:00 am).The date in database is correct.
Here is how I am doing it.
# For uploading
TextField uploadDate = new TextField("uploadDate",Date.class);
uploadDate.add(new DatePicker());
#For displaying(in a ListView)
item.add(new Label("uploadDate ",new
PropertyModel(item.getModel(),"uploadDate ")));
#Environment:
Wicket 1.3.2 (also includes joda time)
MySQL(5.5x)
Can someone please help.
Thanks,
RG

Re: ModalWindow and Ajax?
You can set it as soon as the Wicket js object has been created. You
need to be using wicket 1.3.x for this to work and yes, you will need
to have it set before the onchange.

RE: Get informed about invalidation of a session
I am extending HttpSessionStore and keeping track of my sessions there. I am
able to get a hold of members of my Session while it is being invalidated. I
am not quite sure what you mean by " on the unBind() / onDestroy the actual
session object does not exist anymore", the session seems to be available
and I am able to access members of it as long as I store the Session in
onBind(...). This is what I am doing:
public class ScanManSessionStore extends HttpSessionStore
{
...
private Map sessions = new ConcurrentHashMap();
private Map devices = new ConcurrentHashMap();
protected void onBind(Request request, Session newSession)
{
sessions.put(newSession.getId(), newSession);
}
protected void onUnbind(String sessionId)
{
if(sessions.containsKey(sessionId))
{
Device device =
((ScanManSession)sessions.get(sessionId)).getDevice();
if(device != null)
{
devices.remove(device.getDeviceId());
}
sessions.remove(sessionId);
}
}
...
}
Please let me know if there is a problem doing it this way.

Re: Removing the jsessionid for SEO
the problem is that then you have to have all stateless pages. Else google
can't crawl your website.
And if that is the case then you could be completely stateless so you dont
have a session (id) to worry about at all.

Re: Changing Wickets default styles
More or less. Rearranging the order of the styles, seems to have an
influence. No idea why but it looks ok now. Firebug only showed the first
style (background-image), but changing the order made more show up (not
all). Go figure. But thanks for the input all.

Re: Is there an AJAX Panel in Wicket
wicket has plenty of ajax components out of the box. i think what you're looking for is the lazyloading panel which is from wicket-extensions (i think) have a look at the example(s) on wicketstuff.org: http://www.wicketstuff.org/wicket13/ajax/lazy-loading.1 kumark wrote: > > I was wondering if there is a AJAXPanel available in wicket.

Tabbed Panel
Hi, I want to use tabbed panel in my web application, because this type of navigation seem good for me. I looked the examples and I have this question. Is it posible to use tabbed panel as some page navigator? The situation: My application is composed from few user models and one base model. The base module contains autentication and users management. Each user in system has list of modules he can use. At first the user must sign in to base module and through this he can access the other modules. Each module runs on seperate wicket application and is allowed to get information about logged user from base module. What I want: All I know about other modules are their URLs. So I want to have TabbedPanel and if I click on the tab I want to be redirected to that url. Question: Is there any onClickAction that I can use for redirecting. Or can I give to the Panel model some url and somehow say wicket to go to this URL? Thanks for your advice Milan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: I cannot understand why would a panel have the getparent null
During construction of TodayPanel, it hasn't been added to the page yet so
getParent() is null. Maybe you should do the 'if(user != null) {...' stuff
in @Override ...onBeforeRender() {...}. The first time you're okay because
if (user!=null) fails and getParent() is not executed. The second time it
gets executes.

right. if you strip sessionid then all your nonbookmarkable urls will
resolve to a 404. that will probably drop your rank a lot faster

Wicket fail-over with Terracotta - sticky or non-sticky sessions?
Hi all, I am currently evaluating a Wicket fail-over solution (two equal nodes with a floating IP, probably using Linux Heartbeat) with Terracotta. Of course, it would be desirable to switch between nodes without any impact on a user's session. In order to provide this, the cluster must be able to handle non-sticky sessions. Session clustering works like a breeze with Wicket and Terracotta I already spotted a problem with buffered redirects, that could be avoided with a different rendering strategy (IRequestCycleSettings.REDIRECT_TO_RENDER). However, this problem would only occur if a node goes down just when the client is redirecting - not very likely and probably acceptable as switching over might take a few seconds anyway. Now my question: What other problems could appear when I only use session clustering for fail-over purposes? Can I stay with the default rendering strategy (IRequestCycleSettings.REDIRECT_TO_BUFFER) without clustering the buffer if I accept missing feedback messages in the above scenario? Any further comments on my setup will be appreciated as well!

Re: Removing the jsessionid for SEO
On the other hand, crawling non-bookmarkable pages is not very useful
anyway, since ?wicket:interface url will always get page expired when
you click on the result.
However, preserving session makes lot of sense with hybrid url. Google
remembers the original url (without page instance) while indexing the
real page (after redirect).
I think though that the crawler is quite advanced. I'm would think it
supports cookies (at least JSESSIONID) as well as it evaluates some of
the javascript on page.

[Wicket 1.3.3] Possible wicket:enclosure regression.
Hi All,
I'm experiencing a possible regression for wicket:enclosure in Wicket
1.3.3 (maybe related to the couple of patches that involved enclosures
for 1.3.3). It thought of a regression because the following code
works just fine in 1.3.1, even if I haven't tested it in 1.3.2.
Basically, I have a RadioGroup with a couple of options. When the user
selects the second option, a text field and link (wrapped in an
enclosure) should appear next to the option. If she/he selects the
first option, they should disappear again. Their visibility management
is based on the enclosure.
Set OPTION ONE
Set OPTION TWO
link
On the Java side, the relevant code looks like this (feel free to ask
for further details):
radioGroup.add(new AjaxFormRadioUpdatingBehavior("onclick"){
@Override
protected void onUpdate(AjaxRequestTarget target) {
if (OPTION_ONE.equals(getSelectedOption())) {
textField.setVisible(true);
} else {
textField.setVisible(false);
}
target.addComponent(radioGroup);
}
});
As you can see, I set the visibility of the textField depending on the
selected option and then update the container (the radioGroup). Again,
it worked fine in 1.3.1.
Is anybody aware of this or has anyone else experienced the same
change in enclosure functioning from Wicket 1.3.1 to 1.3.3?
Thank you very much and keep up the good work!

Re: Validate HTML generated from getMarkupResourceStream()
Hi Igor,All
I tried to use MarkupParser as u suggested
This is how my code looks
public IResourceStream getMarkupResourceStream(MarkupContainer container,
Class containerClass){
IResourceStream rStream = new StringResourceStream(HTMLString);
MarkupResourceStream resource = new
MarkupResourceStream(rStream);
MarkupParser parser = new MarkupParser(resource);
try {
parser.parse();
} catch (Exception e) {
setRedirect(true);
setResponsePage(ParseError.class);
}
return rStream;
}
What is really weird is that though the the exception is caught in the catch
block, the program flow continues to "return rStream;" statement and throws
the error on the console again. It doesnt go to the response page that i set
in the catch block.
I am not sure why this happens ?
Thanks

Eeek. Not to be rude, but I really can't read that at all.
Some well-named intermediate variables and a comment might not go amiss.
Your panel is relying on being added to the home page.
This is bad and wrong.
Why don't you pass the calendar into the constructor of the panel?
That would be an awful lot simpler and result in nice readable, correct
code.
I dunno. Give a man a hammer, and everything looks like a thumb...

Re: Validate HTML generated from getMarkupResourceStream()
I got a solution for this and would like to share it with those interested
I replaced the catch block with this code'
catch (Exception e) {
getSession().error("Parse Exception Occured");
throw new
RestartResponseException(ParseError.class);
}
Thanks

Re: Render body only
Yeah. It's a bit nasty, but there's not really any other way to have both the flexibility and the convenience, unless you have some brilliant other idea? It's like jk says, normally you would use the setter, unless you need on-demand evaluation per page-view.

Re: Tomcat dying with Wicket 1.3.2 (Windows / JDK 1.5.0_10)
You can use as many anonymous inner classes as you like. I have them coming out of my ears, personally. It's very odd for tomcat to die with no output. There will be output somewhere. Check logs/catalina.out and also logs/localhost*. If the JVM dies, it will hotspot or even segfault and log that, at least. If you have gradually increasing memory footprint then this should be pretty easy to track down with a profiler. Make sure you run Tomcat with a sensible amount of permanent generation space (128M+).

Re: Tomcat dying with Wicket 1.3.2 (Windows / JDK 1.5.0_10)
The oddness is what baffles me: Tomcat has no output anywhere. I have grepped and tailed the entire Tomcat logs directory, stdout*, stderr*, localhost*, etc. Nothing in eventvwr. It must be memory related, though. There is a steadily increasing memory footprint - it was increasing so fast yesterday because we were getting pounded by tons of traffic and Google's crawler and Ask's crawler all simultaneously. Of course, the traffic was still no higher than it has been in the past - this is definitely a new problem. I redeployed today with the pending 1.3.3 release built by Frank to see if my leak could be the same as Martijn's below, but the memory continues to increase. It will die soon. I have added the parameter to tell it to dump on OOM - hopefully I got the right parameter and it will work. Anyone here know how to (or if you can) use jstat / jmap with tomcat5.exe, running as Windows service? All my development is on Linux machines, and I can easily use those tools, but on the Windows prod environment (ughh), jps doesn't give me a VMID for Tomcat. Thank you for your help!
