True, but a nice boilerplate template would be nice, we could call it "The
GDPR compliance <https://www.eugdpr.org/> model" ;)

It could have methods like isAuthorized before invoking get or set and log
if not authorized and throw exception.

When model access is authroized, it would have methods like logAccess()
which will log (as necessary) how and what is accessed. Logging
implementation will take care of optimizing frequent logs etc.

Possibly it could be applied to both propertymodel and lamba model as a
"model behavior" or something.

I made a jira proposal and we will submit something soon:
https://issues.apache.org/jira/browse/WICKET-6508

Re: How to automatically log access to data objects in wicket gui

[Martin Makundi]

Thanks

We don't want to log ALL invocations, only those in particular wicket
imodels. Aspect will give you all like a profiler, that's not what we want
and it would not have natural visibility to wicket session.

Or do you have a specific example in mind?

How to automatically log access to data objects in wicket gui

[Martin Makundi]

Hi!

We are investigating ways to automatically log access to data objects in
wicket gui.

Oldschool solutions would be, for example to override/customize
PropertyModel and log target object and method invoked, and possibly result
value, together with necessary information from session (timestamp, user
id, authorization level, etc.).

However, with wicket 8 and java 8 lambda possibilities, I am wondering if
anybody would have some ingenious suggestion how to do this very nicely by
implementing own AuditTrailSerializableFunction or similar?

Might need to wrap the data objects in some sort of proxy but that would be
ok:

   - https://gist.github.com/jhorstmann/de367a42a08d8deb8df9
   -
   
https://stackoverflow.com/questions/13356326/how-can-i-log-every-method-called-in-a-class-automatically-with-log4j
   -
   
https://stackoverflow.com/questions/3291637/alternatives-to-java-lang-reflect-proxy-for-creating-proxies-of-abstract-classes


Any suggestions?

Would be cool if blueprints for this were built into wicket.

Thanks.

Re: Ajax refresh and feedback panel

My apologies for a brief ticket. Let's try to elaborate: In Component you
have special processing for IFeedback components using FEEDBACK_LIST
because when other components are rendered, they might throw feedback
messages and make feedback visible.

If feedback is rendered before other components (or in undetermined order),
the feedback might be rendered before another component has thrown a
message.

This is why the IFeedback components are rendered last in normal rendering.

However, in ajax update, such orderinf for IFeedback is not enforced.

I am proposing to add such reordering for ajax update also.

Thanks.

Plese let me know if this requires more clarification. Probably the
existing test case for normal rendering (if such exists) could be modified
for testing the same with ajax update.

Ajax refresh and feedback panel

[Martin Makundi]

Hi!

For normal rendering we have:

/**
* We need to postpone calling beforeRender() on components that implement
{@link IFeedback}, to
* be sure that all other component's beforeRender() has been already
called, so that IFeedbacks
* can collect all feedback messages. This is the key under list of
postponed {@link IFeedback}
* is stored to request cycle metadata. The List is then iterated over in
* {@link #prepareForRender()} after calling {@link #beforeRender()}, to
initialize postponed
* components.
*/
private static final MetaDataKey FEEDBACK_LIST = new
MetaDataKey()
{
private static final long serialVersionUID = 1L;
};

Should there be similar functionality built in for Ajax update /
PartialPageUpdate? It seems to be a typical problem that the feedback of an
ajax update occurs too late.

Re: IndicatingAjaxButton locks other buttons

If you dig with firebug, what can you find that causes the buttons to be

Let's try it first. If it does not pass we can drop joda locally. So long

IMO it's better to big mang whole wicket to drop joda date. All wicket 8
without joda.

Did you drop it from the pom already so that joda is not visible in the

Also if you shut down sessions, you need a grace period which lengthens the

Interesting, it works in a quickstart also on v1.4.

Need to investigate more.

Here is a sample how it works in jsfiddle without problems:
https://jsfiddle.net/#=0SQvHmm6Nj

But when same content is in ajax update it breaks. Wonder what happens to
it before render?

Question about ajax encoding/decoding, problem with image data url

[Martin Makundi]

Hi!

I am trying to display (wicket 1.4) an image using base64 image data
representation.

For some reason the base64 gets garbled every time with ajax.

For example:

src="data:image/png;base64,iVBORw0KGgoNSUhEUgAAAcIAAACWCAYAAABNcIgQAAAKUklEQVR4nO3dzYoc1xkG4PcS+g5cVxDmAmzoC/BCm5BANrMIWXilCwgIvIl3hhC8CUYbe+WFcAgJWdgT8MI2xjEYjA0KGYSjmESYkSxLsmXHk0V1R6dPVff09H/JzwMHaTTVVae7xfnqfOen

becomes (as viewed from firefox developer tools)

Can you group them in javascript and detect group in wicket side, for

I believe this could be handled eleganlty inside wicket when request gets
session it could check for special wicket url parameter or http request
attribute and determine which "wicketsession" the request belongs to and
users's all wicketsessions would be stored in same http session but in a
way that wicket can keep separate wicketsession variables.

Only if user designs it stateless. Otherwise all state is in session by
default. To make it transparent for coder, wicket should handle it.

This does not (transparently) solve the issue with normal session
variables, such as filter etc. models in session. They are still saved if
session is the same.

If all browser windows have same session then a single page application
will always show same wicket TabbedPanel tab for all browser windows
because they share session and they share information about which tab is
active.

Re: Multi-tab / window support in Wicket 7.5

[Martin Makundi]

If one makes a single-page application that has multiple tabs (within one
browser window), and you do not want to make custom logic to allow multi
window/tab (in browser) management into session, it would work best if
there was separate "session" for each browser tab/window inside wicket.

Simplest example is that session has variable "currentlySelectedTab" if you
have two browser windows open both will be racing for this same variable
unless sessions are separated.

So from developer's perspective, would be simplest if wicket transparently
separates sessions for each browser window/tab.

Re: Multi-tab / window support in Wicket 7.5

[Martin Makundi]

This should be built into wicket core, automatic session management. Login
once and enable multiple tabs and a new sub-session for each tab.

If user logs out from any of the sessions, all would be invalidated.

Not sure if this exists yet, but would be needed.

Re: Multi-tab / window support in Wicket 7.5

[Martin Makundi]

We have noticed that most robust if you can get different session for each
tab because the session shares models and will easily conflict if session
is not distinct for each tab.

Re: Approach to changing value in input field before validation

[Martin Makundi]

We have made an utility method that uses reflection to set rawinput, and
have found this very useful.

You set both rawInput and rawInputArray

The prolbem is that if we do it brute force in different thread, no
threadlocal requests will work during persistence and it will throw
exceptions.

How many components do you have?

We have tables with 200x400 cells and each cell has nested structures which

Blocking page serialization

[Martin Makundi]

Hi!

https://issues.apache.org/jira/browse/WICKET-6177

We have a performance issue with our Wicket app, page serialization causes
inconvenience to user because PageStoreManager.storeTouchedPages() blocks
the request until pageSerializer.serialize(page) has been handled.

Could this be solved by serializing the page in a separate thread and let
the request complete?

We have attempted to solve this before for 1.4x but it failed due to
thread-dependenciecs:  https://issues.apache.org/jira/browse/WICKET-5805

Any ideas how this could be solved with 7.x? This would bring a significant
performance boost on component-intensive pages. Simply using detachable
models does not solve the issue when the serialization of the component
hierarchy itself is slow.

Thanks.

1. To answer your question: Is this MoneyLabel your own design? If it is
you are free to implement as you whish, or even drop the first constructor.

2. To give a recommendation on your design, I would attach the
AttributeAppender in any case and only check if the model is negative at
runtime (hollywood principle) like this:

add(new AttributeAppender("class", " negative") {

 @Override
  isEnabled(..) {
 bigDecimalModel.getObject().doubleValue() < 0.0
  }
});

Another way in overriding class:

   */
  @Override
  public void renderHead(HtmlHeaderContainer container) {

Do you have wicket sources available in your dev environment (e.g., via

Put breakpoint inside model.setObject() and start debugging and you will

Transpose html table

[Martin Makundi]

Hi!

We have a html table in wicket implemented as:

foreach :: listview of table rows {
  ..
  foreach :: list view of table cells {
 ..
  }
}

(note: that was pseudocode)


What we would like to do, is offer users possibility to transpose the
table, however, with minimum changes to the code.

Anybody done this? Any insights?

We acknowledge that there are some inherent differences in the transposed
versions of a html table. For example table rows can be ajax updated but
table columns cannot. This might suggest that a div suitable layout should
be used? Or should we simply
ajaxRequestTarget.addComponent(xx::foreach::firstChildOfRow)  visit each
first child of '*row*' when transposed?

Maybe the transpose could be done using a simple onrender string replace
operation (think along the lines of a *complex regexp operation*).

Any ideas, comments?

Would be nice to accomplish this with a neat trick... NOT looking for a js
gimmick because that will be slow with our heavy duty tables.

Re: Transpose html table

[Martin Makundi]

I'd prefer to do it transparently without changing models and minimal
(hardcoded) change to components.

**
Martin

2014-10-03 23:50 GMT+03:00 Paul Bors p...@bors.ws:

 If you want to transpose your table (ie: change the rows and columns)
 then it turn this implies that you want to change the structure of the
 table both the format and the model.
 ie: You need to provide new columns and new data model.

 You would do so in 2 steps:
 1) Create the new table with the new columns
 2) Provide it the new data model

 Then use the addOrReplace(tableId, transposedTableRef) and you're done.

 Otherwise... look at transposing your table in jQuery alone on the client
 side and not on the server side.

Re: Link in Feedback Message

You can look at how a link/button renders its url and render that to the

2014-05-02 22:01 GMT+03:00 Entropy blmulholl...@gmail.com:

 I am currently putting a link into one of our feedback messages so give the
 user a quick way to navigate in response to a particular condition.  I am
 doing it by just writing the tags into the message like so:String url =
 this.urlFor(SearchResultPage.class, new PageParameters().set(newSearch,
 True)).toString();error(The selected records have been successfully
 updated.   Search case for updated records  + url +   .);this
 works...about 90% of the way.  But I recently discovered that I need to do
 a
 little work before that link navigates away.  I need to get the onclick
 event.  How can I get an event on the server that the link has been clicked
 and react to it?I am considering a workaround wherein I could provide an
 extra parameter that the target page detects, and causes it to run my code
 there.  But that's not ideal.  I'd rather keep this page's code in this
 page.  Is there a way to do this?

Re: Multiple F5 refreshes create multiple threads

Hi!

Not knowing what 1.3 does, but 1.4 locks pagemap in org.apache.wicket.Session.

Martin

2013/7/18 Mateusz Mieszkowski mmieszkow...@objectivity.co.uk:
 Hi,

 I'm having a problem with quite old version of Wicket (1.3.6) and I'm 
 wondering if this still exists in the latest version as we're getting ready 
 for upgrading.
 The thing is that if the page opened in browser uses SortableDataProvider, 
 iterator method is executed. So far so good...
 But each time user do F5, page refresh creates new http thread and every one 
 of them is trying to process iterator method.
 Since this is the same user/session, I think it is safe to say that only one 
 thread(that is doing the refresh) is necessary and more refreshes should kill 
 http threads that are working to get the same info.

 The problem in my system was, that one user's F5 blocked and it caused 
 hundreds of refresh and started hundreds of http thread. I imagine that in 
 worse case scenario it could use up whole thread pool and system would be 
 useless for some time.

 I've checked changelogs and jira issues but haven't found anything similar. 
 Could you please let me know if there is a way to avoid such situation?

 Kind regards,
 Mateusz Mieszkowski

Dynamic listview

[Martin Makundi]

Hi!

Is it possible to implement a listview that evaporates on detach and
builds itself again whenever one iterates over its items?

We have a huge page with thuge listview and the
serialization/deserialization of the structure slows down the page.

The models are detachable and maybe the components could be too..?

**

2013/5/28 Martin Grigorov mgrigo...@apache.org:
 Hi,

 You can use ListView#removeAll() in #detach() but then this ListView should
 not have any action components
 like Link/Button and any FormComponents in its items, because they won't be
 reachable.
 It can have pretty much only Labels inside.

 You could use something that builds itself at client side... while at

 Something like

 See for explanation.

 http://www.antiliasoft.com/wicket-angular-demo/

This is mainly read-only? We would like to allow in general all wicket
actions...ofcourse we will go brute force if necessary, but we would
like to try first a wicket 'inline' component that rebuilds itself for
form processing and rendering but evaporates its body on detach.

Re: Dynamic listview

[Martin Makundi]

 You could not use normal form processing, I guess, as there will not be any
 form components at server side... (they will be removed after list is
 displayed). So, you will have to do some ticks to map cliente state with
 server state.

 The examples above could be make to work for non read-only situations...
 but maybe not using wicket default form processing machinery...

Feels like reinventing the wheel at both serverside and html ;)

 You can try to do this in
 org.apache.wicket.markup.html.form.Form#process(IFormSubmitter) {
  rebuild();
  super.process(formSubmitter);
}

Ok. Will try something along these lines.

 You will need to call #inputChanged() to all FormComponents in your
 ListView, because this method is called earlier than
 Form#process(IFormSubmitter).

Could it be possible to hook onto an earlier event before/during
process to allow form to perform that natively?

Hi!

 @Martin,

 Sometimes when wheels at hand are not good enough for a certain terrain you
 should ask yourself if it it not easier to invent a new one.

Only shortsightedness might get one convinced that writing new code is
easier than levaraging legacy..eventually ;) [1]

Re: Dynamic listview

[Martin Makundi]

 I look at the code in master branch (7.x) and I guess you still use 1.4.x.
 In 7.x Form#process() is the first non-final method where you can plug your
 code.
 I doubt that 1.4 is different in this area but you can check yourself.
 Start from Form#onFormSubmitted() and follow the flow.

Thanks, and you are right about 1.4.x, don't fix it until it's broken ;)

Re: Dynamic listview

[Martin Makundi]

 Martin Makundi wants to rebuild the ListView items when the form is
 submitted.
 I.e. the form components will be created and then the form processing will
 proceed.

 Yes, I understand that. But my point would match the info coming from
 client with new component tree being created?  i.e. will listview recreate
 everything in a way making request post data consistent with new created
 components?

This might be a problem, really, the markup ids have random suffix

Re: Dynamic listview

[Martin Makundi]

Ajax update might be tricky, it uses component ids.

  Yes, I understand that. But my point would match the info coming from
 client with new component tree being created?  i.e. will listview recreate
 everything in a way making request post data consistent with new created
 components?


 The new component sub-tree that will be created will be the same as the one
 that has been removed in the previous request #detach().
 I think it should work.

 True.
 You can override FormComponent#getInputName() to make them stable...

Re: Update Model on DropDown Item Selection

2013/4/9 Bruno Moura brunormo...@gmail.com:
 I need to update a model or object immediately after select
 a DropDownChoice item.


 Bellow is the code that I'm working:

 //
 -

  add(new ListView[Company](listCompanies, listData) {

 override protected def onBeforeRender() {
   //
   // ...
   super.onBeforeRender()
 }

 def populateItem(item: ListItem[Company]) = {
   var company = item.getModelObject()

   //...

   val listClients: java.util.List[Client] = clientControler.listClients


   item.add(new DropDownChoice(clientSelection, listClients,new
 ChoiceRenderer[Client](name)))

 //
 -

 In the Listview with properties of Company Object,
 after choose a name property of the DropDownChoice, the model
 Company would be updated with the Client Name selected.

 How can I achieve this?

 Thanks

Re: Illegal utf characters in ajax xml response

[Martin Makundi]

 What are conditions when you want to plug it ?

I know a certain ajax response might contain illegal characters?
Though it might be easier just to filter the known contents.

2012/12/12 Ernesto Reinaldo Barreiro reier...@gmail.com:
 Hi,

 Several times I have encountered the situation where I want to update a
 component via AJAX and this component does not have setOutputMarkupId(true)
 or even the component generates no  visible markup.  All this component
 needs is a way to repaint itself (either by adding some sub-components that
 are re-paintable via AJAX or by generating some JavaScript that will update
 component state at client side). So, what I want is being to do
 target.add(myNotStandardComponent) and wicket to take care of its update...
 Maybe by providing and  interface like

 IAjaxUpdatable {

 void update(AjaxRequestTarget target);

 }

 that marks the  component as being re-renderable via AJAX ... and modify
 AjaxRequestTarget logic to take this into account.

 I gave a look into the sources and the closest thing I have found is

Re: AJAX updating of non typical components

[Martin Makundi]

1. Please also implement this expert/newuser mode as boolean closeonhover
setting inside notificationspanel:

public void onTargetRespond(AjaxRequestTarget target) {
  if(isExpertMode()) {
renderErrorNotifications(target, getString(timeManagement.error),
new NotificationSettings()
.setExpires(false).setUseHoverIntent(false),
NotificationsPanel.CloseOnHoverFunction.instance,
NotificationsPanel.CloseAllBeforeOpenFunction.instance);
  } else {
renderErrorNotifications(target, getString(timeManagement.error),
new NotificationSettings()
.setExpires(false).setUseHoverIntent(false),
NotificationsPanel.CloseAllBeforeOpenFunction.instance);
  }
}

2. Looking at timeManagement.error, does it work with different level
errors/warnings/info?

It appears the mock app does quite some nasty things... this works:

  /**

  public AbstractWebService() {
Application.set(getApplication());

final ServletContext servletContext = getApplication().getServletContext();
final MockHttpSession mockHttpSession = new MockHttpSession(servletContext);
final MockHttpServletRequest mockHttpServletRequest = new
MockHttpServletRequest(Application.get(), mockHttpSession,
servletContext);
final MockHttpServletResponse servletResponse = new
MockHttpServletResponse(mockHttpServletRequest);

final WebRequest wicketRequest =
getApplication().newWebRequest(mockHttpServletRequest);
final WebResponse wicketResponse =
getApplication().newWebResponse(servletResponse);

getApplication().newRequestCycle(wicketRequest, wicketResponse);
  }

Re: Question about unit testing

[Martin Makundi]

https://cwiki.apache.org/WICKET/type-safe-testing-in-wicket.html

=)

2012/9/5 Markward Schubert markward.schub...@gmail.com:
 Hi folks!

 I am sure this is a trivial question, but i am simply too dumb to figure
 this out.
 We have a DopDownChoice, which is prefilled by some modelvalue, given to
 the page.
 Until now i was doing some testing about the model-state before and after
 submitting, which then was correct.
 The problem in the browser was, that the rendered DropDownChoice did  not
 show the preselected value correctly. It could not recognize the equality
 between some member of the available choices and the model's choice.

 Actually it turned out that it was a problem with the model object's
 equals.

 Now my question is:

 What is the most elegant way to unit test the correct rendering of the
 preselection of the DropDownChoice or similar components?
 As said, simply dealing with sumbmit and stuff worked correctly.


 Regards,

 Markward

Hi!

 Wicket 1.4.x is frozen. Only security bug fixes can be committed.
 1.4.21 is being voted and the vote ends tomorrow.

This would be a good opportunity to get widespread experience of this
bugfix, it will benefit also later versions.

 About the patch - I still don't like the leak that it adds -
 o.a.w.Component will know about InlineEnclosure (a specialization of
 Component).

We didn't find a way to do this in the current wicket architecture,
it's simply does not support autocomponents well enough.

 Why you don't like the workaround with the simple WebMarkupContainer
 as a parent of InlineEnclosure ?

Well that was the original boilerplate code we wanted to get rid of in
first place. Ofcourse everything can be done the hard way but built in
support for such basic functionality is beneficial.

Hi!

 Wicket 1.4.x is frozen. Only security bug fixes can be committed.
 1.4.21 is being voted and the vote ends tomorrow.

 This would be a good opportunity to get widespread experience of this
 bugfix, it will benefit also later versions.

 There is a chance to break something else ... The risk is big.

Well.. just run all the tests ;)

 We didn't find a way to do this in the current wicket architecture,
 it's simply does not support autocomponents well enough.

 We know that. We will think how this can be improved for Wicket 7.
 In Wicket 1.5 there is EnclosureContainer which can be used as a
 replacement of (Inline)Enclosure. The difference is that it is not an
 auto component.

 I suggest you to spend some time to upgrade to 1.5.8 or 6.0.0.
 These are the versions we also use in production and it will be easy
 to catch any problems when applying patches by users.

The pace of upgrading from one incompatible wicket to another seem so
fast that we will wait for 7 or 8 or 9 =) We are currently in pretty
far a sweetspot in wicket development, it has almost all the features
we need and we have hacked into it everything it does not have yet
that we need, so upgrading would make no sense, upgrading would take
us way backwards.

 Integer(InlineEnclosure.inlineEnclosureTraversalCounter));

 InlineEnclosure.CALCULATE_INLINE_ENCLOSURE_PERFORMANCE = false;

 Not happy!

Ok, we'll fix that.

 Right. Sometimes it doesn't worth it.
 Then use Wicket 6+ in your next project (if you still like it ;-) ).

Heh, we try to have a platform for rapidly extending our app so a
completely new project from scratch is something I can't immagine yet.
Maybe it will be wicket 60.0 ;)

 Hi All

  I have a dataview table, for 50 rows, it takes around 10 seconds to show
 the page, and the render part take around 8-9 seconds from debug log,  Any
 way to improve this ?

 Each row, there are 2 input DateText filed, three labels, 4 checkbox, 2
 icons and 2-3 placehoder TD.　around 100 characters each row.  Is this a two
 heavy row for wicket ?

Use a real profiler to see.. also running application in deployment

Did you look at wicket ajax debugin browser? It usually gives quite
good clues about what's missing ...

 Hi,

 I am trying to refresh ajax container after firing an event. The code is:

 *final WebMarkupContainer searchContainer = new WebMarkupContainer(

 AjaxFallbackButton ajaxSearchButton = new AjaxFallbackButton(

 }


 Label userLabel = new Label(userLabel, List of Users);
                Label numberOfUserLabel = new Label(numberOfUserLabel, new 
 Integer(
                                numberOfUsers).toString());

                final PageableListViewUserDomain userDomainListView = new
 PageableListViewUserDomain(
                                user, userDomainList, resultsPerPage) {
                        private static final long serialVersionUID = 1L;

                        @Override
                        protected void populateItem(final ListItemUserDomain 
 listItem) {
                        // populating list
                        }

                };

 *               userDomainListView.setVisible(!userDomainList.isEmpty());
                userLabel.setVisible(!userDomainList.isEmpty());

                searchContainer.add(userLabel);
                searchContainer.add(userDomainListView);
                searchContainer.add(numberOfUserLabel);

 But the list view is not getting refreshed? I am using the same technique in
 other pages and it is working.. what be the reason..?? Any suggestion can
 work for me...

Re: Ajax refresh not working in a case .... while working in similar other cases!!!

[Martin Makundi]

Listview has this parameter reuseitems, if you set it to false it will
rebuild when its container is refreshed.

2012/6/9 kshitiz k.agarw...@gmail.com:
 I got the problem atleast...what is happening that it is using the same
 search object (where results are being stored and then displayed in
 container) and not creating the new one for new searches. Actually what I
 want is when user searches anything, the results are refreshed only. I am
 storing the results in an object and displaying them using listview which is
 again a part of container. Can you suggest me anything out here?

clearinput can be used with forms when submit is not done but model is changed

Martin

2012/6/9 kshitiz k.agarw...@gmail.com:
 Okk...actually when I analysed more, what  I found is that when I enter new
 value in text field, the event takes the old value only. Even I am now
 refreshing the form too. Then I found that the field sets its value to old
 one after getting refreshed. My field is of final  type. But that should not
 be the problem as I am using the same technique in other pages too...

Re: Redirect to Wicket page with 301 Moved Permanently

[Martin Makundi]

Also you can hack jetty or similar...

// Force 302 redirect status code into 301 'permanent redirect'
Field statusField = HttpGenerator.class.getDeclaredField(__status);
statusField.setAccessible(true);
Object[] statusMap = (Object[]) statusField.get(HttpStatus.class);
statusMap[HttpStatus.MOVED_TEMPORARILY_302] =
statusMap[HttpStatus.MOVED_PERMANENTLY_301];


2012/5/14 Jeffrey Schneller jeffrey.schnel...@envisa.com:
 Are you using Apache HTTPD in front of your app server?  If so, you can just 
 use a Rewrite Rule to send the 301 redirect with the new URL.  You may want 
 to look into your app server to see if url rewriting is an option.

 Subject: Redirect to Wicket page with 301 Moved Permanently

 Hey guys

 I'm trying to make a redirect form an old url to a new one. The browser url 
 should be changed to the new one and the response code for the original 
 request to the old url should be 301 Moved permanently so search engines will 
 forget the old url.

 Making the redirect by throwing a RestartResponseException works fine, except 
 I can't change the response code from 302 Moved Temporarily to 301 Moved 
 Permanetly

 I've also tried using the RedirectToUrlException, where setting the response 
 code is easy, but I have problems getting it to construct a correct relative 
 url so I don't have to hard code it to a specific host name.

 What is the best way to solve this?

 Thanks in advance

 Jarnis

Re: How do I keep component paths constant across unit tests when using Wicket Tester

[Martin Makundi]

Test safely:

https://cwiki.apache.org/WICKET/type-safe-testing-in-wicket.html

2012/4/21 mmuk...@gmail.com mmuk...@gmail.com:
 I have several wicket tests that target a sortable DataTable, specifically
 ajax-clicking the sortable column headers and asserting the contents of the
 rendered body rows. Now the component hierarchy of the table component's
 descendants is auto generated by the wicket framework, and results in paths
 to the sorting links (ajax) similar to:

    table:topToolbars:toolbars:0:headers:1:header:orderByLink

 However, when the DataTable gets re-rendered across tests, the index of the
 toolbars component is incremented each time i.e similar to:

    table:topToolbars:toolbars:1:headers:1:header:orderByLink

 which then breaks the hard-coded paths of the succeeding tests as they will
 no longer match.

 The code fragment for the datatable construction is as follows:

                final PayeesProvider dataProvider = new PayeesProvider();
                table = new DataTableResponsePayeeDetails(payees, columns,
 dataProvider, rowsPerPage);
                table.setOutputMarkupId(true);
                table.addTopToolbar(new AjaxFallbackHeadersToolbar(table, 
 dataProvider) {

                        private static final long serialVersionUID = 
 -3509487788284410429L;

                        @Override
                        protected WebMarkupContainer newSortableHeader(final 
 String borderId,
 final String property, final ISortStateLocator locator) {
                                return new AjaxFallbackOrderByBorder(borderId, 
 property, locator,
 getAjaxCallDecorator()) {

                                        @Override
                                        protected void onRender() {
                                                System.out.printf(Path: 
 %s\n, this.getPageRelativePath());
                                                super.onRender();
                                        }

                                        private static final long 
 serialVersionUID = -6399737639959498915L;

                                        @Override
                                        protected void onAjaxClick(final 
 AjaxRequestTarget target) {
                                                target.add(getTable(), 
 navigator, navigatorInfoContainer);
                                        }

                                        @Override
                                        protected void onSortChanged() {
                                                super.onSortChanged();
                                                getTable().setCurrentPage(0);
                                        }
                                };
                        }
                });
                table.addBottomToolbar(new NoRecordsToolbar(table));
                add(table);

 To be precise, when I run my tests, the above System.out.printf statement
 prints:

 (1st test)

    Path: payees:topToolbars:toolbars:0:headers:1:header
    Path: payees:topToolbars:toolbars:0:headers:2:header

 (2nd test)

    Path: payees:topToolbars:toolbars:2:headers:1:header
    Path: payees:topToolbars:toolbars:2:headers:2:header

 (3rd test)

    Path: payees:topToolbars:toolbars:4:headers:1:header
    Path: payees:topToolbars:toolbars:4:headers:2:header

 (4th test)

    Path: payees:topToolbars:toolbars:6:headers:1:header
    Path: payees:topToolbars:toolbars:6:headers:2:header
    Path: payees:topToolbars:toolbars:6:headers:1:header
    Path: payees:topToolbars:toolbars:6:headers:2:header
    Path: payees:topToolbars:toolbars:6:headers:1:header
    Path: payees:topToolbars:toolbars:6:headers:2:header

 (5th test)

    Path: payees:topToolbars:toolbars:8:headers:1:header
    Path: payees:topToolbars:toolbars:8:headers:2:header

 Does anyone know how I can force the index generation to be more
 deterministic / repeatable. Alternatively, is there a way of wild-carding or
 otherwise generalising the path, so as to make them immune to these
 increments?

 Any help will be greatly appreciated chaps!

Re: After 1 minute the Pagemap null is still locked by: Thread how to kill this request ?

[Martin Makundi]

We got some of these because of:

- database deadlocks (unsorted race situation)
- non-threadsafe access to hashmaps (hashmap/treemap has cool
possibility to hang when used from multiple threads without
synchronization)
- excplicit lock bugs (reentrantlocks)


I recommend to debug by displaying the stacktrace of the hanged
thread. This can be achieved manually or via kill -3.
