Re: RequiredBorder being applied multiple times in ajax calls
Sorry I can't help you with your question. But may I ask where you get the
PhoneFormatter?

I created the simple RequiredBorder class as follows:
public class RequiredBorder extends MarkupComponentBorder {
public void renderAfter(Component component) {
FormComponent fc = (FormComponent) component;
if (fc.isRequired()) {
super.renderAfter(component);
}
}
}
This basically adds a * after any required fields. It seemed to work
great until I used it with an ajax phone formatter behavior:
new AjaxFormComponentUpdatingBehavior(onchange) {
protected void onUpdate(AjaxRequestTarget target) {
Object oldValue = component.getValue();
String formatted = new PhoneFormatter().format(oldValue);
component.setModelObject(formatted);
target.addComponent(component);
}
}
This caused duplicate * indicators to appear after my phone field when
the phone number changed, one per onchange request. I tried adding a
boolean field to the RequiredBorder so it only gets processed once. This
fixed the phone formatter duplicates, but if the form submits and stays on
the same page, all the * marks disappear from the required fields.
This is definitely some sort of lifecycle problem, but how do you fix it?
On a related note, is it generally a bad idea to mix AJAX and non-ajax
actions? It seems like this is one of many issues I've run into when doing
this.

Re: RequiredBorder being applied multiple times in ajax calls
Sam,
a similar issue happened to the WicketAjaxIndicatorAppender.
take a look at WicketAjaxIndicatorAppender#renderHead to see
how this is solved there.
maybe you can do something similar with your RequiredBorder.

Gerolf

Re: Using generics with some non-generic classes in Wicket
Igor Vaynberg wrote:
well, apparently johan ran into a situation where component? is too
restrictive...
As I understand it, Johan ran into a situation where Component? causes
*warnings* for users who use raw types. Which I've been arguing all
along that they SHOULD get: they should use ComponentObject or
ComponentVoid instead of raw types, or live-with/suppress the warning.
To make it clear, I made the following test class:
public class TestT {
public void doTest(Test? extends Test? test) {
System.out.println(test);
}
public static void main(String[] args) {
TestTestInteger test1 = newInstance(); // fine - no
warnings.
TestTest test2 = newInstance(); // not fine, use of raw type,
warning
Test test3 = newInstance(); // not fine, use of raw type,
warning
test1.doTest(test1); // fine - no warnings.
test1.doTest(test2); // error - generic types don't match, can be
fixed by line below
test1.doTest((Test) test2); // warning - unchecked conversion
test1.doTest(test3); // warning - unchecked conversion
}
public static T TestT newInstance() {
return new TestT();
}
}
As you can see, there is only one case when you get a compile error when
using the ? extends Test? generic type, and that is a case where
there is on the user side an incorrect generic type: TestTest. The
user here declares he's using generics, but then inserts a raw type of a
known generic type - a situation that should not happen.

I don't understand how that changes any of my points. The first is incorrect
(from a generics point of view) since you're referencing an unparameterized
generic type.
So the second gives warnings only in code that is not properly generified...

i do like generics. did i ever say otherwise? the problem here is that

on the other hand if we do scope it as Class? extends Component?
then you can no longer pass a raw reference when calling the function.
But that's exactly the point isn't it? If you're using generics then you
shouldn't be using raw Components anymore...
so we are screwed if we do and we are screwed if we dont, i expected
generics to be better.
Well they definitely could have been better (erasure is terrible if you
ask
me), but I don't see what's wrong in this case. It warns you if you
should
be using a parameterized type but you don't.
And especially if you look at the vote result, I think the majority
wants
the generics...
that vote was before we uncovered this issue. we voted on the idea of
generics, not on the implementation.
That's true, but I wonder if this issue would change the vote much. I
don't
really understand why it's an issue, because you can use generified
Components always: ComponentObject if you don't want to constrain the
model object, and ComponentVoid if you don't need a model.
The question that started the thread was about StringResourceModel which
was
not yet generified, and in that case, the warning seems to me to be
perfectly ok: it just says StringResourceModel should be generified. It's
not a release yet, so that some users who use the current snapshot run
into
these kind of warnings which cannot be removed seems to be fine to me...

Re: overriding getAssociatedMarkupStream

I did exactly what you suggested and it works like a charm.
public IResourceStream getMarkupResourceStream(MarkupContainer
container,
Class containerClass) {
if (html == null) {
final DefaultMarkupResourceStreamProvider
markupResourceStreamProvider =
new DefaultMarkupResourceStreamProvider();
return
markupResourceStreamProvider.getMarkupResourceStream(container,
containerClass);
} else {
StringResourceStream myhtml = new StringResourceStream(new
StringBuilder(html));
// The following line is the line that caused the problem of non inserted
header contributers
//MarkupResourceStream m = new MarkupResourceStream(myhtml);
// The following is the fix
return new MarkupResourceStream(myhtml, new
ContainerInfo(container),
containerClass);
}
}
// In order to keep in my cache the real markup, here is what I did
public String getCacheKey(MarkupContainer container, Class
containerClass) {
if (html == null) {
DefaultMarkupCacheKeyProvider cacheKeyProvider = new
DefaultMarkupCacheKeyProvider();
return cacheKeyProvider.getCacheKey(container, containerClass);
} else {
return null;

(html is a class member that may or may not be available)
It did not work:
1. The Cache keeps the last html markup, so if I open this page once WITH
html != null I get what I want (but with the same problem. look at next
note). If then I open the page and the html IS null, the cache returns
the
earlier page. So this approach is no good.
2. In any case, HeaderContributers that are on components that in the
page
are not added to the output markup.
Are the 2 lines:
StringResourceStream myhtml = new StringResourceStream(new
StringBuilder(html));
MarkupResourceStream m = new MarkupResourceStream(myhtml);
The problem ?

Page expired using LazyLoadPanel and clustering
Hi, I almost have clustering working now - thanks for all the help people have given me. However keep seeing page exprired errors, specifically on a page that has an ajax lazy load panel on it. the page will load fine, but when the lazy load code executes the app throws a page expired error, a bit of digging arround shows me that wicket cannot find the page it has just created in session. I am sure that its the ajax request from the lazy load panel as if I turn off javascript the page loads fine. This does not happen when I dont use terracotta clustering. We are using jetty 6.1.9, terracotta 2.5.4, wicket 1.3.3. Whats strange is that even after I get the page expired error and go back into my app I still have the same jsessionid and looking at the session data in terracotta I see that I still have the same session. Also this doesn't occur on every page with lazy loaded components, just one of them. Its like the session isnt updated before the ajax lazy load panel call is made. Can anyone shed any light on this? I've spent way too much time getting clustering to work already...

WicketStuff YUI simple editor
Hi Im dabbling with using a rich editor. I have a page where I have several ajax tabs, one of them are to contain a editor. I first tried using tinceMCE, but that has troubles with ajax and the header contributions (tinyMCE cant handle it). Then I switched to YUI, but if I add the component again, via ajaxtarget. It actually shows 2 edit windows etc... Also the YUI editor implementation in wicket stuff is not that customizatiable, I cant change the titlebar. It could be a small patch depending on the solution... We could turn our faces at datepicker, which has some facilities for customization. -- -Wicket for love Nino Martinez Wael Java Specialist @ Jayway DK http://www.jayway.dk +45 2936 7684 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
ErrorPage won't render
Hello,
I have a custom error page BaseErrorPage:

public BaseErrorPage() {
super();
}
protected void configureResponse() {
String acceptHeader = getWebRequestCycle().getWebRequest().
getHttpServletRequest().getHeader(Accept);
String contentType = ;charset=UTF-8;
if (acceptHeader.contains(application/xhtml+xml)) {
contentType = application/xhtml+xml + contentType;
} else {
contentType = text/html + contentType;
}
getResponse().setContentType(contentType);
}
}
It's configured to be displayed in case of a runtime exception:
MyApplication.init():
...
getApplicationSettings().setInternalErrorPage(BaseErrorPage.class);
getExceptionSettings().setUnexpectedExceptionDisplay(IExceptionSettings.SHOW_INTERNAL_ERROR_PAGE);
...
I'm testing what happens if MySQL server goes down.
When it happens, first I got a SocketException which is caught and
BaseErrorPage is displayed.
But if I wait for a while (perhaps, until session expires?), I get just a
blank page in browser and in server log I see the following:
unexpected exception when handling another exception: Can't instantiate page

after render using a behavior vs. override in the component
Hello,
I have a MyButton that extends Button.
I have a JavaScript that I need to ad to the output markup after the
button's markup.
I'm trying to do this with two differnet options:
Either I Override onAfterRender in MyButton:
@Override
protected void onAfterRender() {
if (isVisible()) {
getResponse().write(Consts.getResizeScript(getMarkupId()));
}
super.onAfterRender();
}
Or, I add to the button a behavior and write this:
@Override
public void onRendered(Component component) {
if (component.isVisible()) {
component.getResponse().write(Consts.getResizeScript(component.getMarkupId()));
}
}
Now, the situation is like this:
Using the first option (override in the component), the script is added to
the end of the html. Just after the /html
Using the second option (the behavior), the script is added just after the
close tag of the button /button.
Using FF, all is ok, but in IE7, there's a problem in calculating the size
and the button is not shown correctly.
What causes the differences? and how can I manipulate the behavior to work
like option 1 ?
Thanks very much...

Re: Page expired using LazyLoadPanel and clustering
I still get the same behaviour with the httpsessionstore. the problem seems to be that the page isnt put in the page map, so when the ajax call is made to lazy load the panel it cant access the page its on. looking at the http session data in the terracotta admin console i see that the AccessStackPageMap has a page map name set to null, and i cant find the page i should be on in the httpsession. if you use terracotta you shouldnt use the default DiskPageStore i believe but revert back to the 1.2 httpsessionstore.. -- View this message in context: http://www.nabble.com/Page-expired-using-LazyLoadPanel-and-clustering-tp17249134p17250260.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]

Re: after render using a behavior vs. override in the component
thanks,
that's exactly what I did.
I add to my component (button) an AbstarctBehavior, which is an
IHeaderContributor.
I even override renderHead:
@Override
public void renderHead(IHeaderResponse response) {
response.renderCSSReference(/eurekify/style/button/EurekifyButton.css);
response.renderJavascriptReference(/eurekify/style/button/EurekifyButton.js);
//response.renderJavascriptReference(new
JavascriptResourceReference(
//EurekifyButtonBehavior.class, resizeScript.js));
}
The script I am adding to each button comes from a utility class:
static String getResizeScript(String markupId) {
StringBuilder strBuilder = new StringBuilder();
strBuilder.append(script language=\javascript\);
strBuilder.append(document.getElementById('btnObj_);
strBuilder.append(markupId);
strBuilder.append(').style.width = calcBtnSize(');
strBuilder.append(markupId).append('));
strBuilder.append(/script);
return strBuilder.toString();
}
This is the script that I mentioned in my first question.
Again:
If I call this script in the Button class, in the onAfterRender() method, it
is added to the end of the output HTML.
If I call this in the behavior, in the onRendered(Component component), it
is added just after the /button.
I did something like this in the onload script:
window.onload = function(id) {
document.getElementById('btnObj_'+id).style.width = function(id)
{calcBtnSize(id)};
}
firebug says that it can't find document.getElementById('btnObj_'+id) ...

Re: ErrorPage won't render
Yes, as I said in the previous message, I use SpringWebApplicationFactory.

Swarm: Link authorization
Hi,
for every item in a table there's a delete link, which should be only visible
for certain users.
ProductAreaListPage.html:
-
tr wicket:id=productAreaTable class=list
tdspan wicket:id=id[id]/span/td
tdspan wicket:id=name[name]/span/td
tdspan wicket:id=description[description]/span/td
tda wicket:id=editProductAreaEdithellip;/a/td
tda wicket:id=adminProductsProductshellip;/a/td
tda wicket:id=deleteProductAreaDeletehellip;/a/td
/tr
I created a class for the secure link:
---
public abstract class SecureLink extends Link implements ISecureComponent
{
private static final long serialVersionUID = 1L;
public SecureLink(String id, Class c)
{
super(id);
setSecurityCheck(new LinkSecurityCheck(this, c));
}
public ISecurityCheck getSecurityCheck()
{
return SecureComponentHelper.getSecurityCheck(this);
}
public boolean isActionAuthorized(String waspAction)
{
return SecureComponentHelper.isActionAuthorized(this, waspAction);
}
public boolean isActionAuthorized(WaspAction action)
{
return SecureComponentHelper.isActionAuthorized(this, action);
}
public boolean isAuthenticated()
{
return SecureComponentHelper.isAuthenticated(this);
}
public void setSecurityCheck(ISecurityCheck check)
{
SecureComponentHelper.setSecurityCheck(this, check);
}
}
First I tried to use the ComponentSecurityCheck, because I have no real click
target ( I used ProductAreaListPage.class as parameter in the constructor as
dummy). Because the LinkSecurityCheck behaves as ClassSecurityCheck per
default, I called setUseAlternativeRenderCheck to change to
ComponentSecurityCheck.
ProductAreaListPage.java:
-
private class ProductAreaVisibleDataView extends ProductAreaDataView
{
public ProductAreaVisibleDataView(String id, IDataProvider dataProvider) {
super(id, dataProvider);
}
protected void populateItem(final Item item) {
super.populateItem(item);
final ProductArea productArea = (ProductArea) item.getModelObject();
SecureLink deleteLink = new SecureLink(deleteProductArea,
ProductAreaListPage.class) {
private static final long serialVersionUID = 1L;
public void onClick() {
if (productArea.getDeleted())
return;
productArea.setDeleted(true);
productAreaService.save(productArea);
invalidateDataProviders();
}
};
((LinkSecurityCheck)deleteLink.getSecurityCheck()).setUseAlternativeRenderCheck(true);
item.add(deleteLink);
}
}
Because the wicket id deleteProductArea exists for each item in the list, my
policy file would need such permission for each item. This is no real solution,
because I don't know, how many items the list will contain (But it worked in
the example for the first 4 items).
Appl.hive:
// Product area list page - Delete link
permission ${ComponentPermission}
${front}.ProductAreaListPage:resultPanel:productAreaTable:1:deleteProductArea,
inherit, render;
permission ${ComponentPermission}
${front}.ProductAreaListPage:resultPanel:productAreaTable:2:deleteProductArea,
inherit, render;
permission ${ComponentPermission}
${front}.ProductAreaListPage:resultPanel:productAreaTable:3:deleteProductArea,
inherit, render;
permission ${ComponentPermission}
${front}.ProductAreaListPage:resultPanel:productAreaTable:4:deleteProductArea,
inherit, render;
So I tried to change to use the ClassSecurityCheck. There the user must have
rights for the target class. I created a dummy class:
ClickTargetDummy.java:
--*
*package xxx.yyy.zzz.front.security;
public class ClickTargetDummy
{
}
ProductAreaListPage.java:
-
SecureLink deleteLink = new SecureLink(deleteProductArea,
ClickTargetDummy.class) {
private static final long serialVersionUID = 1L;
public void onClick() {
if (productArea.getDeleted())
return;
productArea.setDeleted(true);
productAreaService.save(productArea);
invalidateDataProviders();
}
};
Appl.hive:
-
permission ${ComponentPermission} ${front}.security.ClickTargetDummy,
inherit, render, enable;
This solution works, but I have to create the dummy class. Perhaps other
solutions are possible ???
Thanks in advance

wicket xml - add label as xml element atribute
Hi, I want to generate XML document using wicket but I have this problem. I want to generate something like root var name=a1/ var name=a2/ var name=a3/ otherStructure/ /root I decided to generate the var elements by ListView. This has some problem, because after rendering I have in my XML document some span wicket:id=... elements that I cannot have there. After some investigation and removing wicket dependent markups by getMarkupSettings().setStripWicketTags(true); and setRenderBodyOnly(true); I get this XML code: ?xml version=1.0 encoding=UTF-8? root wicket:container wicket:id=vars span wicket:id=var/ /wicket:container /root where vars is my ListView that add Label var that contains string s = var name=\ + String varName + \ /. I thought this should work, but wicket encode '' and '' as lt; gt; that is not valid XML. All I need is to say wicket to do not encode this characters. Any Idea?? The second idea I have was to do something like : ?xml version=1.0 encoding=UTF-8? root wicket:container wicket:id=vars var wicket:message=name:myLabel/ /wicket:container /root But it has some problem too. I know how to give to wicket:message attribute some value from my properties file, but is there any way to add there a Label?? Thanks for any halp. I did not say that there cannot be any other way how to do it, but I have not found it. Please help. This is very urgent and blokable for me. If I did not find the way how to do it I will have to look up for some another presentation layer. That will be very bad, because except this I found Wicket great. Sorry for my English.

thanks,
that's exactly what I did.
I add to my component (button) an AbstarctBehavior, which is an
IHeaderContributor.
I even override renderHead:
@Override
public void renderHead(IHeaderResponse response) {
response.renderCSSReference(/eurekify/style/button/EurekifyButton.css);
response.renderJavascriptReference(/eurekify/style/button/EurekifyButton.js);
//response.renderJavascriptReference(new
JavascriptResourceReference(
//EurekifyButtonBehavior.class, resizeScript.js));
}
The script I am adding to each button comes from a utility class:
static String getResizeScript(String markupId) {
StringBuilder strBuilder = new StringBuilder();
strBuilder.append(script language=\javascript\);
strBuilder.append(document.getElementById('btnObj_);
strBuilder.append(markupId);
strBuilder.append(').style.width = calcBtnSize(');
strBuilder.append(markupId).append('));
strBuilder.append(/script);
return strBuilder.toString();
}
This is the script that I mentioned in my first question.
Again:
If I call this script in the Button class, in the onAfterRender() method,
it
is added to the end of the output HTML.
If I call this in the behavior, in the onRendered(Component component), it
is added just after the /button.
I did something like this in the onload script:
window.onload = function(id) {
document.getElementById('btnObj_'+id).style.width = function(id)
{calcBtnSize(id)};
}
firebug says that it can't find document.getElementById('btnObj_'+id) ...

you can also do it on component

Hello,
I have a MyButton that extends Button.
I have a JavaScript that I need to ad to the output markup after

I'm trying to do this with two differnet options:
Either I Override onAfterRender in MyButton:
@Override
protected void onAfterRender() {
if (isVisible()) {
getResponse().write(Consts.getResizeScript(getMarkupId()));
}
super.onAfterRender();
}
Or, I add to the button a behavior and write this:
@Override
public void onRendered(Component component) {
if (component.isVisible()) {
component.getResponse().write(Consts.getResizeScript(component.getMarkupId()));
}
}
Now, the situation is like this:
Using the first option (override in the component), the script is
added
to
the end of the html. Just after the /html
Using the second option (the behavior), the script is added just
after
the
close tag of the button /button.
Using FF, all is ok, but in IE7, there's a problem in calculating
the
size
and the button is not shown correctly.
What causes the differences? and how can I manipulate the behavior
to
work
like option 1 ?
Thanks very much...

Re: wicket xml - add label as xml element atribute
I generated my sitemap xml files using wicket, the xml is something like:
?xml version=1.0 encoding=UTF-8?
urlset xmlns=http://www.sitemaps.org/schemas/sitemap/0.9;
url wicket:id=urlList
loc wicket:id=locNodehttp://www.example.com//loc
lastmod wicket:id=lastmodNode2005-01-01/lastmod
changefreq wicket:id=changefreqNodemonthly/changefreq

/url
/urlset
be sure to name the markup file .xml and to override
@Override
public String getMarkupType() {
return xml;
}
in your page ... that should work

The page expired exception fires with this message Cannot find the rendered page in session [pagemap=null,componentPath=60:yellAdTop,versionNumber=0] as i understand it pagemapname=null is just the default page map, so that shouldnt be a problem.

Re: Swarm: Link authorization
Yes there are other solutions :)
In this case you would use a DataPermission.
Something like
permission ${DataPermission} delete_product, enable;
coupled with a DatasecurityCheck on your links like so:
setSecurityCheck(new DataSecurityCheck(delete_product));
will do the trick.

I created a class for the secure link:
---
public abstract class SecureLink extends Link implements ISecureComponent

public boolean isAuthenticated()
{
return SecureComponentHelper.isAuthenticated(this);
}
public void setSecurityCheck(ISecurityCheck check)
{
SecureComponentHelper.setSecurityCheck(this, check);
}
}
First I tried to use the ComponentSecurityCheck, because I have no real click
target ( I used ProductAreaListPage.class as parameter in the constructor as
dummy). Because the LinkSecurityCheck behaves as ClassSecurityCheck per
default, I called setUseAlternativeRenderCheck to change to
ComponentSecurityCheck.
ProductAreaListPage.java:
-
private class ProductAreaVisibleDataView extends ProductAreaDataView
{
public ProductAreaVisibleDataView(String id, IDataProvider dataProvider) {
super(id, dataProvider);
}
protected void populateItem(final Item item) {
super.populateItem(item);
final ProductArea productArea = (ProductArea) item.getModelObject();
SecureLink deleteLink = new SecureLink(deleteProductArea,
ProductAreaListPage.class) {
private static final long serialVersionUID = 1L;
public void onClick() {
if (productArea.getDeleted())
return;
productArea.setDeleted(true);
productAreaService.save(productArea);
invalidateDataProviders();
}
};
((LinkSecurityCheck)deleteLink.getSecurityCheck()).setUseAlternativeRenderCheck(true);
item.add(deleteLink);
}
}
Because the wicket id deleteProductArea exists for each item in the list, my
policy file would need such permission for each item. This is no real
solution, because I don't know, how many items the list will contain (But it

permission ${ComponentPermission}
${front}.ProductAreaListPage:resultPanel:productAreaTable:1:deleteProductArea,

permission ${ComponentPermission}
${front}.ProductAreaListPage:resultPanel:productAreaTable:2:deleteProductArea,

${front}.ProductAreaListPage:resultPanel:productAreaTable:3:deleteProductArea,

invalidateDataProviders();
}
};

This solution works, but I have to create the dummy class. Perhaps other

RequiredBorder draws an asterisk after the field.
* The AjaxFormComponentUpdatingBehavior fires, to format the phone
number. The phone input (TextField) is added to the ajax request target
* The ajaxReqestTarget replaces the components of the phone input.
However, the HTML generated by the border is not replaced. The phone
input border draws around the phone input, and you end up with two
nested borders around the phone input. Repeating the process nests
the borders further.
Possible solutions:
* Remove / disable the border after it renders the first time. This
solves the ajax issue, but when the entire page is redrawn, the
borders all disappear
* Somehow tell the ajaxRequestTarget to replace the input along with
its component border, not just the input. Not sure how to do this.
* Somehow disable the border only for ajax calls
* Don't use the border, manually add a required indicator next to
every required field in my application. Not looking forward to this
one...
Option #2 sounds the most promising, but I don't know where to begin.

Sam,
a similar issue happened to the WicketAjaxIndicatorAppender.
take a look at WicketAjaxIndicatorAppender#renderHead to see
how this is solved there.
maybe you can do something similar with your RequiredBorder.

Re: RequiredBorder being applied multiple times in ajax calls
Matthew, we wrote the phone formatter in house. It's way too messy
to share on here. If I were going to rewrite it, I'd use regex to:
* Strip everything except [0-9x#] from the input
* Everthing before the 'x' or '#' is the phone number, everything
after is the extension
* Count the number of digits in the phone number part. Make sure
there are 10, then format it as (###) ###- ext. ###

Re: Page expired using LazyLoadPanel and clustering
SOLVED! turns out that there are some new images being added to the page, but the image url had been messed up, specifically, was '', so when the page loads, instead of loading the image it makes a call to the home page, so instead of 20 images we get 20 calls to mydomain.com, this then messes up everything and gives me a headache.

Performance testing tools
Hi, This is really not related to wicket but I thought this might still be a good place to ask... I was wondering if anyone knows of a system independent way to performance test Java code in unit tests. I am thinking of something that might hook into the VM and count bytecode instructions or something. Then if a change increases the number of instructions by a certain amount the test could fail so you know you've might have messed with its performance.

Sam,
I think you can do something like this in RequiredBorder#renderAfter:
AjaxRequestTarget target = AjaxRequestTarget.get();
if (target == null) {
// we're in a normal request
// put logic of the original renderAfter here
}
not sure if that works, but you might wanna give that a try.

RE: IChoiceRenderer: RadioGroup CheckBoxMultipleChoice
I agree with your view on keeping Wicket from being bloated. What if the IChoiceRenderer was optional? If you provide it you have automation. If you do not it works as it does now. It's strange that that kind of functionality is provided when multiple selections is needed (i.e. CheckBoxMultipleChoice), but it is not when only one choice is needed (i.e. RadioGroup/CheckGroup). It is an oddity that other components that have choices (i.e. DropDownChoice, etc.) provide a means to use an IChoiceRenderer, but some do not. What if someone is using a RadioGroup/CheckGroup that uses some form of a RepeatingView to generate the Radio/Check options dynamically? In the case where they need to make a selection using a separate choice instance than what is in the list, how would they accomplish that? If they set the choice on the RadioGroup/CheckGroup model it will never be selected because they are different instances, and because there is not IChoiceRenderer it is not possible to define an ID value to determine the equality of the two instances. -Original Message- From: Igor Vaynberg [mailto:[EMAIL PROTECTED] Sent: Thursday, May 15, 2008 5:50 PM To: users@wicket.apache.org Subject: Re: IChoiceRenderer: RadioGroup CheckBoxMultipleChoice well, the whole point of radio/check group is to allow user complete control over markup. the whole point of choice renderer is to automate markup generation, so there is just a big mismatch. eg i always use radio/check group when using a choice renderer would be inconvenient. you can always roll your own subclass, i just dont think something like that would belong in core, its just one more parallel way of doing something. -igor On Thu, May 15, 2008 at 2:44 PM, Hoover, William [EMAIL PROTECTED] wrote: yes... sorry CheckGroup is what I meant.

Otherwise, how else can you use two different model object instances that share the same ID to be selectable? - 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] - 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] - 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]
Thread safety for components
I'm trying to get a handle on thread-safety for components. I'm new to Wicket. My best information, so far, comes from the previous discussion Wicket Session and threading: http://mail-archives.apache.org/mod_mbox/wicket-users/200801.mbox/thread Eelco Hillenius, in response to Sebastiaan van Erk, wrote: Yes. We try our best to make pages/ components as thread safe as possible... Is there anywhere a small piece on how to deal with threading within Wicket (i.e., what is/is not synchronized in a request/response roundtrip?). I did some quick searching in the mailing list archives and google, but could not find anything related to version 1.3. Pages are synced on pagemaps, which basically relates to browser windows. RequestCycles are separate instances which are not reused, so no sync needed there. Sessions are not synced so you need to sync manually. Though in practice this wouldn't give much trouble to start with. Applications are shared an not synced. During form processing, however, my own pages are *not* synced on their pagemaps (at least not on their monitor locks). I placed this is in my code: assert Thread.holdsLock( /*page*/this.getPageMap() ); This asserts false during the setting of TextField models (Wicket 1.3.2), and false during the call to Form.onSubmit().

Re: Invoulentary session sharing/leakage in Wicket 1.3.x
Guys has this been resolved?? We have been having some customers complain as well (some sending screen shots of others peoples data as proof). Because our users click streams are available publically at their control, we had thought jsessionids occurring in the click stream were being maliciously hijacked. We plugged that hole disallowing any jsessionid to be part of url (via Servlet filter) - yes this of course means JavaScript must be enabled. This involuntary session sharing is still occurring. We are running release 1.3.2. Johan Compagner wrote: I know all that, but i dont know how this could happen in wicket. I think it is user code because if you have a bufferedresponse that has a string buffer filled then it is very strange that the output stream is already used, i am very curios how both can be used by wicket in the same request, wicket only uses outputstream itself for resources and a redirect to buffer (the actual redirect) the last part this really cant happen because there shouldnt be anything in the response. The first part cant also happen because we dont render a page or something if a resource request target is the response target.. So it seems to me that that it is usercode that writes directly to the stream and let wicket still do something On 5/5/08, lars vonk [EMAIL PROTECTED] wrote: Hi Johan, This exception occurs if you obtained the servletresponse via the ServletResponse.getOutputStream() and are *trying *to obtained the writer via ServletResponse.getWriter() at the same time. According to the javadoc of ServletRespone you can either use getOutputStream or getWriter to write the body: Either this method or [EMAIL PROTECTED] #getOutputStream} may be called to write the body, not both. Jetty tracks this using an inner flag. This flag is only reset on the ServletResponse.reset() method, which I believe is called at the end of the servletrequestcycle. If I look at Wicket's the WebResponse class I see several ServletResponse.getWriter *and* ServletResponse.getOutputStream calls. You can't mix those two when writing the servletresponse. Maybe this helps with tracking where it goes wrong. Cheers Lars PS. The exception would have been IllegalStateException(WRITER') if you obtained the ServletResponse.getWriter() and are *trying* to obtain the ServletResponse.getOutputStream at the same time.

Re: Thread safety for components
I'm not sure precisely what the current synchronization implementation is and there may be some edge cases that are not perfect, but the overall design is single-threaded, meaning you should not need to provide synchronization. Some requests, like image resources would potentially be handled in parallel, but anything that calls user code ought to be synchronized by Wicket so you don't have to think about it. I suppose there might be complications with asynchronous Ajax events, but I would expect these cases are already handled. Is there some specific problem you have run into?

I want to change the background image and color on different wicket pages.
All my pages inherits from
a root page that is the master layout. How can this be done.
I must have it like
body,html{
background: .
}
so that I have browser compability. Right now I have this in a external css.
How can I add this dynamically from my wicket page?

Re: chaning background
Sorry... a little early. Not chaning, changing. I have looked at HeaderContributor() but that requires a css file and I want just to append like SimpleAttributeModifier but the html, body can't have the same id and If I add a wicket:id on body I get exception when extending the wicket page. -- View this message in context: http://www.nabble.com/chaning-background-tp17268044p17268081.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]
