This is exactly why ListViews should not be used to work with database data
unless you override getListItemModel() to return a model to represent the item
itself like Sven mentioned in his reply.
Here are three different ways to fix your problem from worst to best:
1. add(new AjaxButton( "delete , new EntityModel(item.getModelObject()))
Where EntityModel knows how to load the entity from the database - ie the jpa
model sven mentioned.
2. New ListView<….> {
getListItemModel(imodel list, int index) { return new
EntityModel(list.getobject().get(index)); }
This is the same as above but has the advantage of item.getmodel() returning
the better model
3. Use a RefreshingView or a DataView instead.

Re: wicket-el - is this a safe way to hook into wicket?
On Wed, Dec 18, 2013 at 9:40 PM, Steve Coughlan shadders@gmail.com wrote: A few weeks back I made a post about the first version of universal expression language for wicket. Since then it's come quite a way. The initial version hooked into by implementing IMarkupResourceStreamProvider for markup owning MarkupContainers (Panel, Page etc...) and by regenerating markup fragments for markup receiving MarkupContainers (ListView). Unfortunately due to the fact that the EL expressions need to be evaluated on every request this meant a huge performance hit (about 75% less than standard wicket) due to forcing wicket to constantly parse markup on every request cycle. The current evolution of wicket-el hooks in very differently. My first preference was to create a dynamic version of Markup and MarkupFragment that replaces MarkupElements that contain EL expressions with a dynamic version. Unfortuantely this was impossible because I need to subclass Markup (wicket uses a few case of 'instanceof Markup') and Markup has many final methods. And simply wrapping all the MarkupElements isn't possible because RawMarkup is a final class and is also reference inside wicket with 'instanceof'. So the only way I could think of to do it (which I've done and it works) is to create a subclass of Markup (ModifiableMarkup) that takes the original wicket-parsed markup, and adds all it's elements. Then during the onRender phase EL enabled components call ModifiableMarkup.resolve(ExpressionResolver, ELParseMatchList) which internally replaces RawMarkup elements belonging to that compenent with an EL resolved version. This is done just before calling super.onRender(). Sounds ugly but it works and performance is now equal to standard wicket (in some cases can even be a little faster due to not needing PropertyModels). Because the Markup instances are now mutable I can't use wicket's markup cache as it's one per class and ModifiableMarkup.resolve method could easily be called by many threads at once. So I've had to implement caching per thread/class combination. i.e. ELPanel will have a cached instance of Markup for every thread. My question is twofold: 1/ As I have no choice but to leave ModifiableMarkup mutable, what is the purpose of making Markup immutable? From what I can see from browsing wicket source all it achieves is a bit of safety and releasing some resources from the backing XmlTags in the MarkupElements. Is there any other purpose to it? i.e. can you forsee any problems with using a mutable instance of Markup for rendering? because its immutable it is thread-safe. making it mutable would add a lot of complexity to make sure it is thread-safe. -igor 2/ Is the per thread/class caching strategy really safe? The only way I could think it could be broken is if it was possible for the server to suspend a thread mid-render cycle and give another request use of that thread. If that happened the new request would overwrite the markup expressions and the when the old resumed and expressions already resolved would have values from the the request that interrupted it. As far as I'm aware with the work I've done with Jetty and NIO connectors before this will only happen if you ask Jetty to do it while processing the request. Is this a possibility with wicket or can I rely on a complete render cycle to happen uninterrupted before the thread is reused for another request? - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: How to prevent a concurrent click on ajax links (AjaxFallbackLink)
the easiest way to do it is to tell the ajax channel used by the link
to drop requests if one is already in progress, this is called an
active channel.
add(new AjaxLink(..) {
updateAjaxAttributes(attrs) {
attrs.setChannel(new AjaxChannel(blocking, AjaxChannel.Type.ACTIVE));
}
}
if you wan to block across a group of links then create a channel
singleton and give it to all the links.

Unfortunately the link unavailable any more. May be anybody can repeat a

I really appreciate any help you can provide.

Re: What is the purpose of Validatable.model?

Re: Handling user-specific timezones
we should write components that work with multiple types.
for example this is what code of a DateLabel might look like:
@Override
public void onComponentTagBody(MarkupStream markupStream, ComponentTag
openTag) {
String body = ;
Object date = getDefaultModelObject();
if (date != null) {
if (date instanceof ReadablePartial) { body = ... }
else if (date instanceof ReadableInstant) { body = ... }
else if (date instanceof Date) { body = ...}
else if (date instanceof Timestamp) { body = ... }
else {
throw new IllegalStateException(Object of type : +
date.getClass().getName() + is not supported);
}
}
replaceComponentTagBody(markupStream, openTag, body);
}
we are not using a converter because DateLabel carries a format string
as a property.
such a component is convenient because you dont need to worry if you
are using it with older api that has Date or a newer one that has Joda
we cannot go solely on threeten because version 1.0 is not coming
until jdk8 and only with jdk8.

no, it just means we *add* handling for javax.time types when they

having support for both joda and javax.time sounds a bit too much
additionally https://issues.apache.org/jira/browse/WICKET-466 is since
2007. Everyone knows the issues with j.u.Date/Calendar.
The fact that JDK development is slow doesn't mean that we should be slow
too. It is 6 years since this request has been made. Isn't it time to drop
support for j.u.Date/Calendar ?
there are a lot of issues with j.u.Date. no one here is going to
dispute that. but, even with all these issues it is still a widely
used class, and will continue to be long after jdk8 is released.
i do not care if internally wicket used joda or anything else to
represent time. we can encapsulate whatever mechanism we want. but,
externally we should support j.u.Date as well as joda, etc.
for example, jpa codebases which need to be portable or jee apps can
only map j.u/s.Date and j.s.Timestamp because those are the only
temporal types jpa has support for. if we do not support these
directly then the users will either have to convert their domain to
perform conversion in getters/setters or use a model adapter to bind
to those types. either way, its a hassle, especially since its really
easy for us to support these types directly.

Re: Wicket RepeatingView refresh / rerender ? Possibilities? [List items missing]
repeatingviews are manual repeaters - meaning they do not get updated once they are built. you should most likely use a RefreshingView, or navigate back to the page in such a way that a new instance is created which will rebuild the repeatingview. -igor On Tue, May 7, 2013 at 5:59 AM, DaWicketUser d3nny...@web.de wrote: Hi Community, i got a little problem with my wicket application.

Re: Wicket 6.x and Repeaters API change to use longs
yes. when i was looking at this i thought about making the dataprovider paging param ints, but then the long return type didnt make sense. since count() returns a long its feasible to request offsets in the long range - eg user presses last page and you actually have more rows then an int can hold. so rather then going with a mixed approach that made the code base a big mess i went with the biggest type everywhere, which is a long. what i did at my day job is to create an entity data provider that handles all these inconsistencies and castings and exposes a consistent api to how our application works... -igor On Fri, May 3, 2013 at 8:58 AM, Paul Bors p...@bors.ws wrote: All good and solid, but take for example Javax's Query API: http://docs.oracle.com/javaee/6/api/javax/persistence/Query.html#setFirstRes ult(int) Since Wicket's DataProvider now offers the first and count as longs, one would have to cast first to an int to pass it through the JEE 6 API, right?

That's why I was thinking using instanceof as less as possible is more preferred and indeed cleaner instead of checking package names.

Re: Repainting repeaters - why the need for the enclosing element
this has to do with how wicket repaints things with ajax. what it does
is render the component and then replace the component's root dom node
in the existing markup with the one rendered via ajax.
lets take a simple example of attaching a listview to a [tr]
add(new ListView(rows, ...) { });
[table][tr wicket:id=rows]...[/tr][/table]
suppose there are 3 items in the list
when rendered during initial request it looks like this
[table][tr][/tr][tr][/tr][tr][/tr][table]
now you say target.add(listview) to repaint it via ajax.
what will be rendered is this: [tr][/tr][tr][/tr][tr][/tr] but there
is no root dom node to replace...thus the problem
if you attach a webmarkup container to [table] and then repaint that
instead of the listview then the markup getting repainted is:
[table][tr][/tr][tr][/tr][tr][/tr][table] and that has the one
top-level tag you need to replace in markup.
you might argue that wicket should be smart and handle each [tr] separately.
what happens if elements change order? wicket would need to reorder
the nodes as well.
what happens if some elements in the list are no longer there? they
need to be somehow removed from the markup - but this information is
missing from the markup generated by re-rendering a repeater for ajax.
we cant just say : take the parent of the [tr] tag, clear all
children, add ones in ajax response. the reason we cannot is because
there may be two repeaters attached under the same parent node and you
may only be repainting one of them.
a possible solution would be to keep a list of previously rendered
repeater item ids in the repeater - that way we would know what to
nuke in the markup. but that would make the internals more
complicated.
adding a parent container and repainting that seems like a simple
solution to the problem.

Hi,
AFAIK the solutions for large numbers of cells in GUI frameworks are:
1) Do not render cells that are not in the scrollable view
2) Create components only per once row or column and provide cell
renderers. See javax.swing.table.TableCellRenderer
With these approaches there is basically no limit to the amount of
data that can be displayed on the screen.
The current architecture seems to be here that the entire view is
rendered on the server irrespective of how much of it is displayed
in the client. This rules out 1)
Still the current architecture allows to exploit 2) which would solve
your performance problem if applicable to your use case. But that is
theory until someone creates TableCellRenderer for Wicket.

that was nonsense :P

Hi,
AFAIK the solutions for large numbers of cells in GUI frameworks are:
1) Do not render cells that are not in the scrollable view
2) Create components only per once row or column and provide cell
renderers. See javax.swing.table.TableCellRenderer
With these approaches there is basically no limit to the amount of
data that can be displayed on the screen.
The current architecture seems to be here that the entire view is
rendered on the server irrespective of how much of it is displayed
in the client. This rules out 1)
Still the current architecture allows to exploit 2) which would solve
your performance problem if applicable to your use case. But that is
theory until someone creates TableCellRenderer for Wicket.

Hi,
Lets say I have about ~100.000 of MarkupContainer objects that I want to
put into a ListView or RepeatingView.
This works fine functional wise... It's rather slow though.
It boils down to:
MarkupContainer:
1309 private Component put(final Component child)
1310 {
1311 int index = children_indexOf(child);
1312 if (index == -1)
1313 {
1314 children_add(child);
1315 return null;
1316 }
1317 else
1318 {
1319 return children_set(index, child);
1320 }
1321 }
and the call to children_indexOf(child) where it loops over all it's
existing children and compares the id's until a match is found.
With an increasing amount of children this can get rather slow...
I though off overruling some functionality in the MarkupContainer class
since I'm sure that for this list of items the children will be unique
in
their id and don't need that lookup, and overruling the put or
children_indexOf function would give me enough power to skip that
performance impacting part. But most functions have private access,
leaving me nothing to control the adding of child components to a
MarkupContainer.
Does anyone else have experience with adding rather large quantities to
something like the ListView and/or RepeatingView?
Or is there another way of rendering this large amount of containers?
Thanks in advance.
Kind regards,
Marco

In Wicket 1.4 I had logic in the resolve() method of the WebRequestCycleProcessor where I basically called setResponsePage() with the new parameter and threw a AbstractRestartResponseException(). In Wicket 6 I was able to achieve the same by creating a custom Mapper that extends the MountedMapper. In this Mapper I added logic to the parseRequest method to check if the UrlInfo includes the parameter and if not create a new UrlInfo instance based on the original one that includes the parameter. This works but it requires that all pages are mounted with this specific Mapper. Is there a better way to add this logic so that it automatically applies to every request and does not require the developers to use the custom mapper?

It's not there if you are using onInitialise, as it's part of the component lifecycle, you know what state the parent component is in. thats why bind() makes no guarantee about the state of the component, it is simply called when the behavior is added to the component. What happens if the behaviour is added after the component has already been initialized? Does its oninitialize() still get called? Of course - I'd expect adding a Behaviour to a Panel is no different from add a Label to a Panel. The onInitialise in the Behaviour would be called the same as the Label - as and when it's part of the component tree. As behaviours are re-useable extensions to components, I'd expect them to behave in the same way. there is a small problem with this line of thinking: behaviors are different from components in that one instance of a behavior can be added to multiple components. so behavior A gets added to a component that is already initialized - no onInitialize call, then same instance gets added to component B that is not yet initialized, now onInitialize is called? doesnt make any sense unfortunately. perhaps what you can do is describe your concrete usecase for needing this method and we may be able to better help you. -igor Cheers, Col. -Original Message- From: Igor Vaynberg [mailto:igor.vaynb...@gmail.com] Sent: 07 February 2013 19:14 To: users@wicket.apache.org Subject: Re: Behaviour.onInitialise() What happens if the behavior is added after the component has already been initialized?

In this case the tool being used to scan for those vulnerabilities is HP Fortify http://www8.hp.com/us/en/software-solutions/software.html?compURI=1349399#.URFMM6WbR2o I wanted to get the communities feedback on critical security issues that were presented based on this tool (I'll leave my opinion out of it for now) and if other teams are using are using this software - what is their process for evaluating/fixing/etc these kinds of issues in open-source software. Appreciate your input. Issue 1 - wicket-ajax-jquery.js:651 (Open Redirect) *Abstract:* The file wicket-ajax-jquery.js passes unvalidated data to an HTTP redirect function on line 651. Allowing unvalidated input to control the URL used in a redirect can aid phishing attacks. invalid. the javascript code referenced here is only invoked as a callback to an ajax request object. the url passed in is generating on the server. in order to take advantage of this vulnerability the attacker would need to gain javascript execution via a GET url at which point they may easily execute window.location=foo themselves rather then utilizing our javascript. *Explanation*: Redirects allow web applications to direct users to different pages within the same application or to external sites. Applications utilize redirects to aid in site navigation and, in some cases, to track how users exit the site. Open redirect vulnerabilities occur when a web application redirects clients to any arbitrary URL that can be controlled by an attacker. Attackers can utilize open redirects to trick users into visiting a URL to a trusted site and redirecting them to a malicious site. By encoding the URL, an attacker can make it more difficult for end-users to notice the malicious destination of the redirect, even when it is passed as a URL parameter to the trusted site. Open redirects are often abused as part of phishing scams to harvest sensitive end-user data. *Recommendations*: Unvalidated user input should not be allowed to control the destination URL in a redirect. Instead, a level of indirection should be introduced: create a list of legitimate URLs that users are allowed to specify, and only allow users to select from the list. With this approach, input provided by users is never used directly to specify a URL for redirects. Issue 2 - FileUpload:253 (Path Manipulation) *Abstract:* Attackers can control the filesystem path argument to createTempFile() at FileUpload.java line 253, which allows them to access or modify otherwise protected files. invalid. the prefix part of the file name is fixed to be the user's session id and request timestamp - so the user cannot access other user's temp files by manipulating the file name. *Explanation*: Path manipulation errors occur when the following two conditions are met: 1. An attacker can specify a path used in an operation on the filesystem. 2. By specifying the resource, the attacker gains a capability that would not otherwise be permitted. For example, the program may give the attacker the ability to overwrite the specified file or run with a configuration controlled by the attacker. In this case, the attacker can specify the value that enters the program at getId() in FileUpload.java at line 251, and this value is used to access a filesystem resource at createTempFile() in FileUpload.java at line 253. *Recommendations:* The best way to prevent path manipulation is with a level of indirection: create a list of legitimate resource names that a user is allowed to specify, and only allow the user to select from the list. With this approach the input provided by the user is never used directly to specify the resource name. In some situations this approach is impractical because the set of legitimate resource names is too large or too hard to keep track of. Programmers often resort to blacklisting in these situations. Blacklisting selectively rejects or escapes potentially dangerous characters before using the input. However, any such list of unsafe characters is likely to be incomplete and will almost certainly become out of date. A better approach is to create a white list of characters that are allowed to appear in the resource name and accept input composed exclusively of characters in the approved set. Issue 3 - WicketServlet:327 (Race Condition: Singleton Member Field) *Abstract:* The class WicketServlet is a singleton, so the member field wicketFilter is shared between users. The result is that one user could see another user's data. invalid. this field is meant to be shared. -igor *Explanation:* Many Servlet developers do not understand that a Servlet is a singleton. There is only one instance of the Servlet, and that single instance is used and

Starting with Wicket 6 we use semantic versioning for the future development of Wicket, and as such no API breaks are present in this release compared to 6.0.0. New and noteworthy === JQuery was upgraded to 1.8.3, bootstrap to 2.2.2. JSR 303 BeanValidation support -- Native support for BeanValidation (JSR 303) was added as an experimental module and released as version 0.5. You can grab it by using these maven coordinates: org.apache.wicket:wicket-bean-validation:0.5:jar or by pasting in the pom snippet below: dependency groupIdorg.apache.wicket/groupId artifactIdwicket-bean-validation/artifactId version0.5/version /dependency Note that this is an experimental module and that it is not released under the semantic versioning rules. Use at your own risk. Hierarchical feedback panel --- A new kind of feedback panel was introduced: a hierarchical feedback panel. A specialized feedback panel that only displays messages from inside a fence defined by a container component. Instances will not show messages coming from inside a nested fence, allowing the nesting of these panels to work correctly without displaying the same feedback message twice.

Re: Are Wicket models loaded concurrently ?
the bug is that something does not serialize access to the page. the contract on models and components is that they always run in a single-threaded environment. this is what allows the user code to be simple and free of any synchronization logic. so whatever push/pull/whatever framework you are using - it should properly synchronize access to the page instance that owns the models. -igor On Wed, Dec 26, 2012 at 6:16 PM, Hendy Irawan he...@soluvas.com wrote: I think I just found a bug ...

Looks awesome!
One suggestion/question about it (might sound silly at first but keep an
open mind).
I understand you're implementing the JSR-303, but I was wondering if it
would be possible to allow some of the settings be borrowed from other
annotation framework like Hibernate or some other 3rd party not necessary
out of the box but perhaps via a user defined mapping?
Given your example POJO:
public class Person implements Serializable
{
@NotNull
@Size(min = 2, max = 30)
private String name;
...
If one were to use the same POJO to map it via Hibernate the code would look
like:
@Entity
public class Person implements Serializable
{
@NotNull
@Size(min = 2, max = 30)
@Column(name = full_name, nullable = false, length=30)
private String name;
...
That seems like duplicated meta data to me since you're defining the same
info twice such as the null state and length in two or more different
annotations.
i believe you are coming into this from the wrong angle. the
integration should not be between Wicket validation and hibernate
annotations, the integration should instead be between bean validation
(303) and hibernate annotations.
303 provides the validator and the metadata constraint discovery which
i use. if you choose to integrate between wicket and hibernate
annotations you have to basically build a parallel 303 implementation.
instead, figure out how to integrate hibernate annotations with 303
and you get to piggy back on everything thats already there.

new hierarchical feedback panel added
a common question on this list is how to build hierarchical feedback
panels. i just checked in my attempt to help solve this problem into
master. here is the javadoc that explains what it does. feedback
welcome.
-igor
/**
* A specialized feedback panel that only displays messages from
inside a fence defined by a
* container component. Instances will not show messages coming from
inside a nested fence, allowing
* the nesting of these panels to work correctly without displaying
the same feedback message twice.
* A constructor that does not takes a fencing component creates a
catch-all panel that shows
* messages that do not come from inside any fence or from the {@link Session}.
*
* h2IN DEPTH EXPLANATION/h2
* p
* It is often very useful to have feedback panels that show feedback
that comes from inside a
* certain container only. For example given a page with the following
structure:
* /p
*
* pre
* Page
* Form1
* Feedback1
* Input1
* Form2
* Feedback2
* Input2
* /pre
* p
* we want Feedback2 to show messages originating only from inside
Form2 and Feedback1 to show
* messages only originating from Form1 but not Form2 (because
messages originating from Form2 are
* already shown by Feedback2).
* /p
* p
* It is fairly simple to configure Feedback2 - a {@link
ContainerFeedbackMessageFilter} added to
* the regular {@link FeedbackPanel} will do the trick. The hard part
is configuring Feedback1. We
* can add a {@link ContainerFeedbackMessageFilter} to it, but since
Form2 is inside Form1 the
* container filter will allow messages from both Form1 and Form2 to
be added to FeedbackPanel1.
* /p
* p
* This is where the {@link FencedFeedbackPanel} comes in. All we have
to do is to make
* FeedbackPanel2 a {@link FencedFeedbackPanel} with the fencing
component defined as Form2 and
* Feedback1 a {@link FencedFeedbackPanel} with the fencing component
defiend as Form1.
* {@link FencedFeedbackPanel} will only show messages that original
from inside its fencing
* component and not from inside any descendant component that acts as
a fence for another
* {@link FencedFeedbackPanel}.
* /p
* p
* When created with a {@code null} fencing component or using a
constructor that does not take one
* the panel will only display messages that do not come from inside a
fence. It will also display
* messages that come from {@link Session}. This acts as a catch-all
panels showing messages that
* would not be shown using any other instance of the {@link
FencedFeedbackPanel} created witha
* fencing component. There is usually one instance of such a panel at
the top of the page to
* display notifications of success.

Re: Ideas on implementing dynamic addition of components that use AJAX?
historically the components you add from auto resolvers are added via the autoAdd() method, not using add(). these components only exist during render of the page (in detach() phase all auto-added components are removed). the thinking here is that auto resolved components are not normal components. because they are resolved so late in the lifecycle they do not typically implement the entire lifecycle like onInitialize(), onConfigure(), etc may not necessarily be called. such components are also not meant to have their own state. because of these reasons we remove them at the end of the request and readd a new instance next time the page is rendered. these are basically transient render-once components. starting with wicket 1.5, however, components are able to resole their markup earlier in their lifecycle. the reason auto resolved components are added so late and treated specially was because the markup was only available during render. if you are using 1.5 or 6 you can build your own mechanism. something that kicks off a page/panel's oninitialize(), gets the markup, walks it, and adds any components - maybe ones you mark by special tags in your own namespace. the problem here is that even if you can find these components you may still not be able to put them into the right parent because in onInitialize() the parent may not yet be added to the container. so perhaps you should have some mechanism that kicks off when page#onComponentAdded() is called. you can pull the newly added component's markup, see if it has any of these special components defined as a child of the components markup, and add them right there. since you are doing this early on these components will have normal lifecycle and should work just like any other component. hope this helps you get started. keep us in the loop. -igor On Thu, Nov 22, 2012 at 4:54 PM, Chris Colman chr...@stepaheadsoftware.com wrote: We've been using Wicket since version 1.3 and have been using the IComponentResolver interface with great effect to allow the web designers to effectively 'plug and play' with the Wicket components. We have multiple layouts using Wicket's 'variation' feature. Each designer can build up a different collection of components in any particular variation as they like - all without changing the Java code. Normally, without using IComponentResolver, the Java code to support such flexibility would be mind boggingly complex and ugly but with an IComponentResolver we simply have code that's capable of instantiating any component anywhere - and it works and the resulting code is extremely elegant. While we use lots of AJAX it is restricted to components that are explicitly added to components i.e. not added dynamically via the component resolver because such components are not able to contribute anything to the head section. This is starting to become a bit of a problem as we want some of the more advanced components (with AJAX) to take part in the 'plug and play' flexibility. We also are starting to get into using Twitter Bootstrap with Wicket and much of the 'funkiness' in some of those components comes from JS that needs to be injected into the header. Is anyone else using this 'plug and play' capability of Wicket made available via the IComponentResolver interface or is everyone sticking to the rigid 1 to 1 relationship between markup and the corresponding statically coded Java component hierarchy? (which we found quite constricting after a few weeks =] ) I understand that there are some workarounds suggested for empowering AJAX in dynamically added components but they seem to involve manually parsing markup in the onInitialize method and then explicitly adding any required components there - it sounds non ideal and would result in an extra parse of all page and panel markups I would think - which may affect performance. Would we be parsing raw XHTML at that stage or would a preparsed DOM be available to search through? What is the fundamental issue with the Wicket architecture that prevents dynamically resolved components from contributing to the header? Is one of the causes the fact that by the time the ComponentResolver is being called the header has already been rendered to the response stream and so once body rendering commences no more header injection is possible? If so, that could probably (thinking out aloud without an in depth knowledge of Wicket's internals =] ) be solved by splitting the rendering into two streams: header injection goes to current output stream while body rendering goes to a temporary 'body' stream. When the page render is complete the output of the body is then appended to the current stream, after the header rendering. This would allow header injection to continue during processing of the body markup because both are not being sequentially output to the same stream. There was mention of another issue - something about auto added (component

how is an ip address of some proxy in your data center more useful? i

I would suggest something like

to ensure that the given value is an IP. What would you say? Bug,

Re: [announce] Wicket-CDI for Wicket 6.0.0 released

you can pass in the page id obtained from page#getpageid() as a bookmarkable url, then to navigate back to the original page you can do setResponsePage(new PageReference(pageid).getPage()) this will, however, leave you on a nonbookmarkable url when you come back. if you want bookmarkable urls all the way around then you need to do what stateless frameworks do, pass the return url to the detail page as a parameter. -igor On Mon, Sep 17, 2012 at 3:07 PM, Nelson Segura nsegu...@gmail.com wrote: Hello, I have a very common pattern in which from a list, I can to detail of an element in the list.

Hello,
Now that most of my production code is migrated to 1.5 I started
migrating my tests. The first problem I ran into is with
BaseWicketTester#startPanel and
BaseWicketTester#getComponentFromLastRenderedPage.
In 1.4 I could use startPanel and then find components with
getComponentFromLastRenderedPage using paths relative to the panel. In
1.5 I need to prefix those paths with panel:. Adding this prefix in
hundreds of tests is overwhelming.
BaseWicketTester#startComponentInPage(Class) JavaDoc says that it can
use RELATIVE paths to look up components, but this is not the case for
BaseWicketTester#startComponentInPage(Component)! That's because the
method with Class parameter sets ComponentInPage#isInstantiated flag
which is then checked in getComponentFromLastRenderedPage. I think all
overloaded startComponentInPage methods should do that.
Is this a bug?
Thanks,
Alec

Re: select2 localization questions
you should declare your Select2Choice as Select2ChoiceShort since
that is its model type. once you do this the compiler will tell you
that your TextChoiceProvider should be TextChoiceProviderShort

Okay. Just one more question.
I have a domain model (HrpBbheerk) which contains a Short column. I would
like to fill this via Select2Choice.
I read the select2-examples but not able to get rid it.
So the steps I took.
1. Fill my hepar5list list from my domain model (HrpBbhepar5). This contains
couple of columns but I only need for two. One for value and one for
description. If possible I don't want to create another wrapper class just
for this case.
2. Create a form, added a model (HrpBbheerk)
3. Added a new Select2Choice to the form with that Short column mentioned
above.
Snippets:
...
fillHepar5(); // step 1
HrpBbheertk heertk = fillHeertk();
IModel model=new CompoundPropertyModel(heertk);
sform.setModel(model); // step 2
Select2Choice dimelemert = new Select2Choice(dimelemert,new
PropertyModel(sform.getModel(),dimelemert),new Hepar5Provider()); // step
3
..

Re: Dataview: need message nothing found
add a webmarkup container that is only visible when the dataview has no records.
public class NoRecordsContainer extends WebMarkupContainer {
private final AbstractRepeater repeater;
public NoRecordsContainer(String id, AbstractRepeater repeater) {
super(id);
this.repeater = repeater;
setOutputMarkupPlaceholderTag(true);
}
@Override

super.onConfigure();
setVisible(repeater.size() == 0);
}

Re: IExceptionMapper to notify support of errors
perhaps an error occurs during an ajax request whose response is ignored. or maybe it happens during resource processing... eg tinymce requests a resource, wicket doesnt find it and throws an exception. your panel renders. but, because the url was for a resource the response is ignored because its not a 200 response. -igor On Wed, Aug 15, 2012 at 9:40 AM, jchappelle jchappe...@4redi.com wrote: I have written an IExceptionMapper that notifies our support team if an unexpected exception occurs. It will redirect the user to our ErrorPage and in the ErrorPanel.onBeforeRender I send a notification via email in a new Thread. This mostly works except we are getting several false positives.

Here are the things that I don't understand about this behavior. If my notification code is in the onBeforeRender of my ErrorPanel, then how does this code execute and the user never see the panel?

Re: IExceptionMapper to notify support of errors
not really. like i said, if this happens during a resource url then the browser will never show the response. your best bet is to use a timer or any other callback that gets triggered via javascript, so you know the user sees the error panel. -igor On Wed, Aug 15, 2012 at 10:22 AM, jchappelle jchappe...@4redi.com wrote: Thanks for the quick response Igor. Are there any callback methods in Panel that will allow me to put my notification code and guarantee that it will be rendered to the user?

Re: DataTable in wicket 6 using wicket:container
how exactly would you attach a link to a span? link would complain that it is not attached to an anchor tag... -igor On Wed, Aug 1, 2012 at 2:45 PM, Steve Lowery slow...@gatessolutions.com wrote: The DataTable was changed in wicket 6 to use wicket:container instead of span on the td and th elements ( https://issues.apache.org/jira/browse/WICKET-4224). While this fixed the issue described in the ticket, it can make dealing with the DataTable a little more cumbersome and introduces a new bug in my opinion. If I want to simply add a link into a column (very usual use case), I cannot do so now without creating a dummy panel around it, or at least I don't know of a way. Any component with attributes in the componentTag itself get dropped because the wicket:container tag doesn't get rendered, only the child does. It works fine with plain Label's, but that's about it. I can create a handful of dummy components that wrap the columns real content, but wasn't sure if this was the best way to do it. Other people will certainly have the same issues when they upgrade to wicket 6. If you want me to create a quickstart for the link issue, I can do that. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Other wicket components like DropDown has a clear pattern: the renderer is used only for rendering purpose, there's a model to store selection and a model to store choices options. Still, I can't figure out how to do the very same thing with AutocompleteTextField. The best I can get is: TextField codeField = new AutoCompleteTextFieldJSONObject(code, model, JSONObject.class, renderer, new AutoCompleteSettings()); I'm using an AbstractAutoCompleteTextRenderer and a PropertyModel binded to a JSONObject variable. It all works but when I submit the form, it says me that the selected string is not a valid JSONObject, so he cannot attach it to the field. the ITerator returned by AutocompleteTextField.getChoices(String input) is an Iterator of JSONObject. I expect that when I submit, the setObject receives the selected JSONObject, not the String I do render using a specific Renderer. How can that be done?

Hi All,
The problem is : I got a NullPointerException after using @Inject
environment : wicket 1.6 snapshot - cdi (weld) - inject -
NullPointerException - tomcat 7 / jboss AS 7
module 1 : bookstoreservice (with a beans.xml file)
module 2 : bookstoreweb (with a beans.xml file)
in the bookstoreservice module I have these 2 classes:
@ApplicationScoped
public class Clock {
public DateTime getTime() {
return new DateTime().now();
}
}
@ApplicationScoped
public class BigBenClock {
@Inject
Clock clock;
public BigBenClock() {
}
public DateTime getBigBenTime() {
return clock.getTime().plusHours(2);
}
}
First use : All works fine
In a webpage, I have
@Inject
Clock clock;
@Inject
BigBenClock bigBenClock;
add(new Label(time, new PropertyModel(this, clock.time)));
add(new Label(bigBenTime, new PropertyModel(this,
bigBenClock.bigBenTime)));
All works fine, thanks to Igor's example
https://www.42lines.net/2011/11/15/integrating-cdi-into-wicket/
Second use : NullPointerException
If I use the injection in the bookstoreservice module with no injection in
the webpage like this
@Inject
Clock clock;
add(new Label(time, new PropertyModel(this, clock.time)));
BigBenClock bigBenClock = new BigBenClock();
DateTime bigBenTime = bigBenClock.getBigBenTime();
I get a NullPointerException. The BigBenClock's clok is null.
Same result in Tomcat 7 and Jboss AS7.
This is how I start the Wicket application
getComponentInstantiationListeners().add(new JavaEEComponentInjector(this,
new ModuleJndiNamingStrategy()));
BeanManager beanManager = (BeanManager)getServletContext().getAttribute(
Listener.BEAN_MANAGER_ATTRIBUTE_NAME);
new
CdiConfiguration(beanManager).setPropagation(ConversationPropagation.NONE).configure(this);
Any advice ?
Thanks
