Serialize exceptions
Hi I get a serialize exception in a panel of mine its correct that one of the contained fields cannot be serialized, however this field are injected and should not be touched by the checker, the field are marked with the @inject annotation. I'm using guice for injection.. Any thing obvious wrong with this?

i guess I'll have to implement that filename-solving part manually by
creating my own PackagedTextTemplate and changing the constructor where that

Re: How to set HTTP Header Content-Length in IResourceListener?
Response is there to provide an abstraction for e.g. portlets, and other types of requests. As long as you are working in a web container and don't install or use extensions (that I am unaware of exist), casting is fine.

Hi,
We needed once to do something similar and we came with the following solution:
override FormComponent#validate() for the components which have
validators and do:
public void validate() {
if (getForm().findSubmittingButton() != saveButton) {
super.validate()
}
}
i.e. validate for all buttons but the one you want to skip.

Wicket 1.4.20 : error message Access denied to (static) package resource

Re: Wicket 1.4.20 : error message Access denied to (static) package resource
Hi,
Yes, in 1.4.20 Wicket uses SecurePackageResourceGuard by default
because there was a security related issue. We will send an official
mail soon.
Many of the common extensions are allowed by default but .htm is not
one of them. You need to add this to YourApp#init():
IPackageResourceGuard packageResourceGuard =
getResourceSettings().getPackageResourceGuard();
if (packageResourceGuard instanceof SecurePackageResourceGuard)
{
SecurePackageResourceGuard guard =
(SecurePackageResourceGuard)
packageResourceGuard;
guard.addPattern(+*.htm);
}

Re: Wicket 1.4.20 : error message Access denied to (static) package resource
Hi !
I faced a similar issue, but with PDF files used as PackageResource.
It boils down to wicket relying now by default on
SecurePackageResourceGuard which only authorizes file with some
extensions (defined in the SecurePackageResourceGuard constructor).
What I did was create my own subclass of SecurePackageResourceGuard as
follows:
public class MyResourceGuard extends SecurePackageResourceGuard {
/**
* Default constructor
*/
public EDCResourceGuard() {
super(new SimpleCache(100));
addPattern(+*.pdf);
}
}
And then in my Application subclass, in the init method, I do
getResourceSettings().setPackageResourceGuard(new MyResourceGuard ());
I guess if you simply add the following line
addPattern(+*.htm) to your MyResourceGuard constructor, your error
will go away.
Hope this helps !
Antoine.

[1.5] unwanted page refresh
Good afternoon, I have a couple of ModalWindow s in my code that respond to closing using an AjaxButton and its AjaxRequestTarget.

Mysterious application crash
Hi, I've run into a very odd situation and I have no idea, how to find out what is going on... The situation is as follows: 1. I have a base page that contains some markup and components. 2. I have a second page, that extends the base page but does not add any markup or components, i.e the HTML is empty besides des wicket:extend tag and the Java Class is entirely empty 3. The base page is mounted as 'base', the child page is mounted as 'child' 4. I open the child page in the browser, it shows ok (all the contents of the base page) 5. I open the base page in the browser and I get an exception: Root cause: org.apache.wicket.markup.MarkupNotFoundException: Markup not found for Component: [HtmlHeaderContainer [Component id = _header_0]] at org.apache.wicket.Component.internalRender(Component.java:2315) at org.apache.wicket.Component.render(Component.java:2275) at org.apache.wicket.MarkupContainer.renderNext(MarkupContainer.java:1474) at org.apache.wicket.MarkupContainer.renderAll(MarkupContainer.java:1638) 6. I try to open the base page in another browser, I get the same exception! For me, that indicates that the application was somehow corrupted. Is that possible? Or do I miss something obvious here?

registerForm.add(nameField);
*this.add(organizationList = new ListView(organizationList) {

tdselect wicket:id=organizations/select/td

/form
But I am getting the error:
*Unable to find component with id 'organizationList' in

I have followed the same procedure as given in various examples in
google.
So what is the cause of error?

Re: Dynamically sized image
Hey Dan, sorry for the late reply and thanks for your suggestion. If it is necessary with ajax for a good solution, I'm not fanatic in resisting it. I would prefer to wrap it in a reusable wicket component, thou, and I have not yet figured out to do this. It seems that depending on http://benalman.com/projects/jquery-resize-plugin/ Ben Alman's jQuery resize event might save a bit of coding and avoid minding custom js code to the window's resize event. I have tried to use various WiQuery classes to implement it with no success. Just recently I became aware of the AjaxLazyLoadPanel class, and my current idea is to override the protected void handleCallbackScript(final IHeaderResponse response, final String callbackScript) method to make a script that also provides the size for the first rendering cycle. I'm a bit stuck on how to construct the js callbackScript, thou. If someone has a pointer on how to get started on this I would appreciate it. Otherwise I will post the solution when I finally work one out. It may take a while as this is a nice-to-have feature in the current project I'm working on and I rarely have time to throw after it, -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Dynamically-sized-image-tp4456657p4492790.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Two submit buttons in a form, one of them does not trigger validation
yeah, but its pretty easy to visit all formcomponents and call
convertinput()/updatemodel() from one place rather then changing every
form component to be aware of the button...just sayin...

Hi,
We needed once to do something similar and we came with the following
solution:
override FormComponent#validate() for the components which have
validators and do:
public void validate() {
if (getForm().findSubmittingButton() != saveButton) {
super.validate()
}
}
i.e. validate for all buttons but the one you want to skip.

I have a form that has two submit buttons. One is a Save button that just

I need to make some of the fields mandatory, but there is a requirement
that
the Save button should not trigger any validators, the user should always
be able to save his form.
Is there a clean way how to achieve this behaviour in Wicket? I'm using
version 1.4.

Re: Dynamically sized image

Streaming a zip file then going back to previous BreadCrumbPanel
Hi,
I have a Wizard that is inside a BreadCrumbPanel. I have implemented a
method in the onCancel that goes back to the previous BreadCrumbPanel. This
is how it is implemented:
ListIBreadCrumbParticipant participants =
crumbModel.allBreadCrumbParticipants();
crumbModel.setActive(participants.get(participants.size() - 2));
This works fine. The problem is in my onFinish. This wizard creates a zip
file that exports some documents from our system. The code for this is
below. I would like the onFinish to send the zip file back to the user and
then return to the previous BreadCrumbPanel. I'm not able to do that with
the code below. Does anyone have any ideas on how to do this?
ResourceStreamRequestHandler target = new ResourceStreamRequestHandler(new
AbstractResourceStreamWriter()
{
public void write(Response response)
{
try
{
ResponseOutputStream out = new ResponseOutputStream(response);
ZipOutputStream zip = new ZipOutputStream(out);
policyService.exportPolicies(zip, policyService.getPolicies());
zip.close();
}
catch(IOException e)
{
throw new RuntimeException(Failed to export all policies., e);
}
}
@Override
public String getContentType()
{
return application/zip;
}
});
target.setFileName(All Policies.zip);
getRequestCycle().scheduleRequestHandlerAfterCurrent(target);
ListIBreadCrumbParticipant participants =
crumbModel.allBreadCrumbParticipants();
crumbModel.setActive(participants.get(participants.size() - 2));
I'm using wicket 1.5.4 by the way.
Thanks,

LDM - correct construction
Is this the correct construction of a LDM where I need to use a service bean to
access my database? The IMyService bean is injected on the page and passed to
the LDM. Does this make the LDM hold a reference to the IMyService bean and
possibly keep a connection from being put back into the c3p0 db connection
pool? After some period of time my application is blocked with all threads
waiting on a connection to the db.
Should I be injected the IMyService bean into the LDM using the commented out
code. Thanks for any help.
public class MyLDM extends LoadableDetachableModelcom.example.MyObject {
//@SpringBean
private IMyService service;
private String id;
public MyLDM(String id, IMyService service) {
this.id = id;
this.service = service;
}
//public MyLDM(String id) {
//this.id = id;
//}
@Override
protected com.example.MyObject load() {
//InjectorHolder.getInjector().inject(this);
return service.getMyObject(this.id);
}
}
Re: LDM - correct construction
Jeffrey,
That won't prevent a connection from being released. The LDM holds a
reference to the page, and the page has a serializable proxy to the service
implementation. No problem there. Injecting the service into the LDM is
only an advantage if you want to share it among pages; then the LDM can be
static and its page reference goes away.
It sounds like your service implementation may have an issue. Does your
service manage its own connections? If so, is it a singleton? Other than
that, I'd guess there's a bug in your transaction management such that a
transaction gets started but not finished.

RE: LDM - correct construction
My service implementation uses hibernate dao objects which should be managing
its own connections via the c3p0 connection pool. All my service objects and
Dao objects are marked as singletons in my Spring applicationContext.xml file.
I don't think any of my transactions are failing as it would most likely throw
an exception if the there was a problem performing a transactions and all
exceptions are logged (at least I believe they are).
I will most likely put the following c3p0 settings in place and wait to see
what comes out of this in production.
c3p0.unreturnedConnectionTimeout=30
c3p0.debugUnreturnedConnectionStackTraces=true
This should give me a stack trace of what checked out a connection, where that
connection hasn't been returned to the pool in 30 seconds. It will be a slight
performance hit on production but I should be able to find the problem very
quickly.
Thanks.

That sounds like a good strategy. Generally speaking, applications use an
open-session-in-view pattern which makes it easy to ensure that the
Hibernate session gets closed. As long as that happens, the (mis)handling

After upgrading from wicket 1.5.0 to 1.5.1+ we have a simple problem
We have the following simple setup: BasePage checks if user is logged in, if not (and this is not the LoginPage), RestartResponseException(LoginPage.class); LoginPage extends BasePage; contains a form to login; The application runs in the root context. Now on 1.5.0 this works like a charm; After upgrading to 1.5.5 we get infinite redirects; testing versions in between, we've found that the problem occurs = 1.5.1; Here's what debugging shows: 1) When we hit the root url (homepage), it redirects to /login 2) When the LoginPage (mounted at /login) is hit, WebPageRenderer:266 redirects from /login to /login?0 3) When /login?0 is hit, WebPageRenderer:214 redirects from /login?0 to /login and this loops back to (2) I've also learned that this does not occur if we do not run the app in the root context, so it appears to have to do with url handling. Looking at the wicket 1.5.1 changelog I don't see anything that was changed to break this. Before doing more debugging, does anyone have a clue what might cause this?

The ajax idea is a good idea although I would use that as a last resort. I was hoping that their was a cleaner way that doesn't generate a lot of traffic to the server. I wonder if I could create an IRequestHandler that holds a reference to two other IRequestHandlers. The first being the streaming zip file, the second being one that updates the breadcrumb model and refreshes via ajax. I don't know exactly how to implement that second one though.
