RE: Log bookmarkable page link execution

[Chris Colman]

Not sure if this is the same as what you want but we've made all our
page classes derive from a common base which performs the logging
function in the constructor so that you can't miss a log. You can do
some reflection to grab the name of the page class instance or create a
method that is overridden by every page class.

The later method has the advantage that it can include context
information as well.

Hi!

What can be the cause of this error, how can there be concurrent
modification to a item on a page being serialized?

Re: How to Handle ResourceStreamNotFoundException

[hfriederichs]

Hi Dan,

This is /exactly/ what I was looking for! A simple solution for a simple
problem. I used a (subclass) of a WebResource before for another use case,
and that worked fine, so I got blinded by wanting to reuse the same
solution, at least that is what I think has happened. Whatever.

Thank you very much for your interest and help.

Regards, Hans

how to test what radio is checked in a radiogroup?

[Mathilde Pellerin]

Hi all,

I have a form with a Radiogroup :

In my form, I have a radiogroup like this :
RadioGroup genre = new
RadioGroup("genreDestinataire");
genre.setRequired(true);
genre.setLabel(new Model("Genre destinataire"));
genre.add(new Radio("femme", new Model("f")));
genre.add(new Radio("homme", new Model("h")));
genre.add(new Radio("mixte", new Model("b")));
form.add(genre);

This radiogroup match the genreDestinataire field in Questionnaire Entity
(with a CompoundPropertyModel).

In my unit test, I try to check what radio is selected, but I don't find
how...
I can get Model Object from radioGroup like this :
String genreObtenu =
((RadioGroup)form.get("genreDestinataire")).getDefaultModelObjectAsString();

but it works even if none of radio is checked. It happen when I fill the
form with existant Questionnaire : radiogroup model is ok, but none of radio
is checked.
Before correct this bug, I want to reproduce it in test, but I didn't find
how to see if a radio is checked or not : I didn't find any method like
"isChecked" or "isSelected" on Radio Component.

Is there any way to check that ?

Thanks.
M.

Re: how to test what radio is checked in a radiogroup?

[Mike Mander]

Hi all,

I have a form with a Radiogroup :

In my form, I have a radiogroup like this :
 RadioGroup  genre = new
RadioGroup("genreDestinataire");
 genre.setRequired(true);
 genre.setLabel(new Model("Genre destinataire"));
 genre.add(new Radio("femme", new Model("f")));
 genre.add(new Radio("homme", new Model("h")));
 genre.add(new Radio("mixte", new Model("b")));
 form.add(genre);

This radiogroup match the genreDestinataire field in Questionnaire Entity
(with a CompoundPropertyModel).

In my unit test, I try to check what radio is selected, but I don't find
how...
I can get Model Object from radioGroup like this :
 String genreObtenu =
((RadioGroup)form.get("genreDestinataire")).getDefaultModelObjectAsString();

but it works even if none of radio is checked. It happen when I fill the
form with existant Questionnaire : radiogroup model is ok, but none of radio
is checked.
Before correct this bug, I want to reproduce it in test, but I didn't find
how to see if a radio is checked or not : I didn't find any method like
"isChecked" or "isSelected" on Radio Component.

Is there any way to check that ?

Thanks.
M.

Maybe you can get the component from last renderered page (by path to 
component) and cast it to radio.
Then you can compare raw input of group with the radio value (see 
Radio.onComponentTag).


Other option would be to use the tag tester provided by WicketTester. See

/**
 * Modified version of BaseWicketTester#getTagByWicketId(String) 
that returns all matching tags

 * instead of just the first.
 *
 * @see BaseWicketTester#getTagByWicketId(String)
 */
public static List getTagsByWicketId(WicketTester 
tester, String wicketId)

{
return 
TagTester.createTagsByAttribute(tester.getServletResponse().getDocument(),

"wicket:id", wicketId, false);
}

Re: how to test what radio is checked in a radiogroup?

[Mathilde Pellerin]

Thank you for your answer Mike.

I didn't find out how could I try with Radio.onComponentTag, so I tried with
tagTester.

I think it could be a good solution, so I did that :
TagTester tagFemme =
tester.getTagByWicketId("formCreationQuestionnaire:genre:femme");
TagTester tagHomme =
tester.getTagByWicketId("formCreationQuestionnaire:genre:homme");
TagTester tagMixte =
tester.getTagByWicketId("formCreationQuestionnaire:genre:mixte");
Assert.assertNotNull(tagFemme);
Assert.assertTrue(tagFemme.hasAttribute("checked"));
Assert.assertFalse(tagHomme.hasAttribute("checked"));
Assert.assertFalse(tagMixte.hasAttribute("checked"));

but my tagTester are always null ! I checked path many times, and I tried
other way to instantiate tagTester, but without success.
I already used TagTester in other test before without problem, and I really
don't understand why it is always null here...

Can you provide output from WicketTester.debugComponentTree()?

 I add WicketTester.debugComponentTrees() in my test juste before
assertNotNull which failed like this :

Re: Log bookmarkable page link execution

[Dan Retzlaff]

Mike, since I didn't really understand your use case, I'm not sure a
site-wide link decorator is the best way to go. You might keep it simple and
just print a log statement when certain actions are performed, then
periodically grep through your log files to generate statistics. My
suggestion assumed you wanted to know both the "from" and "to" of each
bookmarkable link click.

Chris, I can see how that would work. I guess I'm of the opinion that Wicket
provides enough listener hooks that inheritance needn't come into the
picture. It's easy to inherit one behavior, but things can get messy when
you want to mix in multiple behaviors. If some use case requires
per-component customization as you suggest, you can throw an interface
specific to the use case onto those particular components and do some
"instanceof" checks in your application-wide listeners.

Re: Unexpected RuntimeException when trying a project with a DataTable

[Dan Retzlaff]

Hi Ahmed,

I recommend running Wicket in an IDE with a debugger and stepping through
your code. Personally I deploy my Wicket applications into an Apache Tomcat
server set up within Eclipse. There are many other servlet containers and
IDEs that will work though.

Re: Highlight 2 Fields as Errors, but only 1 Error in FeedbackPanel

[eugenebalt]

Yeah, I can do error() on individual components in a form, but how do I do a
*single* error, while *highlighting* several fields? Is there a separate
highlight method?

Re: Strange error

How reproducible is this? I don't know how the serialization process itself
would cause this, but if it's intermittent then maybe there's a threading /

Re: Unexpected RuntimeException when trying a project with a DataTable

I did so but it's a bit confusing . Is there any book or a tutorial that
describes the sequence of calls of the framework ? And how should my code
flow ?

Re: Unexpected RuntimeException when trying a project with a DataTable

[Martin Grigorov]

The problem is clear:

java.lang.NullPointerException
at 
com.ahmed.task.main3.UserProvider$SortableDataProviderComparator.compare(UserProvider.java:21)
at 
com.ahmed.task.main3.UserProvider$SortableDataProviderComparator.compare(UserProvider.java:1)

Wicket asks your DataProvider for data and your UserProvider fails
with NPE at line 21.

Re: Unexpected RuntimeException when trying a project with a DataTable

[Dan Retzlaff]

If you put a breakpoint where the NullPointerException is thrown, your
debugger should show you the call stack which tells you the sequence of
calls that got you there. In your particular case, the crux is the
"Collections.sort(newList, comparator)" call which sorts newList using your
custom comparator. I'd guess that newList contains an object that is missing
a property required by your comparator.

Re: Strange error

[Martin Makundi]

Hi!

I don't know how to reproduce it... and I wonder, because there is
pagemap lock, what else can be modifying stuff during page
serialization?

Re: Strange error

[Dan Retzlaff]

I tend to agree that odds of a Wicket bug in this area are small. Can you
think of a case in your application where a component has a HashMap of
objects which have a TreeMap of objects? Maybe the source of this collection
within your application is the problem.

Re: how to test what radio is checked in a radiogroup?

[Mathilde Pellerin]

hum, yes and no... I mean, page is loaded by an ajax response (AjaxLink),
but then there is no Ajax.
This is the entire test, maybe it can help :

@SuppressWarnings("unchecked")
@Test @Transactional @Rollback
public void testStory23_TA21_VerificationInitialisationBoutonsRadio(){
tester.startPage(RecapitulatifQuestionnairePage.class);
tester.assertRenderedPage(RecapitulatifQuestionnairePage.class);
tester.clickLink("questionnaireEnCours:1:modifier");
tester.assertRenderedPage(CreationQuestionnairePage.class);

Form form = (Form)
tester.getComponentFromLastRenderedPage(
"formCreationQuestionnaire");

//On vérifie que le formulaire est préremplie avec le questionnaire
sélectionné
Questionnaire qObtenu = form.getModelObject();
Assert.assertNotNull(qObtenu);

//Vérification du sexe des destinataires
String genreAttendu = qObtenu.getSexeDestinataire().toString();
String genreObtenu =
((RadioGroup)form.get("genre")).getDefaultModelObjectAsString();
Assert.assertEquals(genreAttendu, genreObtenu);

TagTester tagFemme =
tester.getTagByWicketId("formCreationQuestionnaire:genre:femme");
TagTester tagHomme =
tester.getTagByWicketId("formCreationQuestionnaire:genre:homme");
TagTester tagMixte =
tester.getTagByWicketId("formCreationQuestionnaire:genre:mixte");
tester.debugComponentTrees();
Assert.assertNotNull(tagFemme);

Assert.assertTrue(tagFemme.hasAttribute("checked"));
Assert.assertFalse(tagHomme.hasAttribute("checked"));
Assert.assertFalse(tagMixte.hasAttribute("checked"));
}

Re: how to test what radio is checked in a radiogroup?

[Mike Müller]

If i'm not completely wrong is tester.clickLink(path) a wrapper for 
tester.clickLink(path, isAjax = true). So you get an ajax response.
You can check that by calling tester.dumpPage().

The problem is that wicket tester only works on page markup. It is not
working on ajax response markup (at least i didn't get it to work.
Once i've wrote an extractor. Maybe that helps you to.


package de.frontend.wicket.testtools;

public final class AjaxResponseComponentMarkup {

private final String _ajaxResponseMarkup;
private final int _componentTagStartPosition;
private final int _componentTagEndPosition;

public AjaxResponseComponentMarkup(String ajaxResponseMarkup) {
_ajaxResponseMarkup = ajaxResponseMarkup;
_componentTagStartPosition = 
_ajaxResponseMarkup.indexOf("");
}

public String extract() {
StringBuilder result = new StringBuilder();
if (hasComponentTag()) {

result.append(_ajaxResponseMarkup.substring(startOfAjaxResponseComponentMarkup(),
 endOfAjaxResponseComponentMarkup()));
}
return result.toString();
}

private int startOfAjaxResponseComponentMarkup() {
String cdataTag = "";
return 
_ajaxResponseMarkup.substring(_componentTagStartPosition, 
_componentTagEndPosition).lastIndexOf(cdataTag) + _componentTagStartPosition;
}

private boolean hasComponentTag() {
return _componentTagStartPosition != -1;
}
}
 
This is only extracting the markup in CDATA of ajax response.
Use it this way:



private void assertExpandedNodeAt(int row) {
List t = TagTester.createTagsByAttribute(new 
AjaxResponseComponentMarkup(_tester.getServletResponse().getDocument()).extract(),
 "wicketpath",
"brdPage_availability_tariffTable_rows_" + row 
+ "_cells_1_cell_junction", true);
Assert.assertTrue("Node " + row + " is collapsed", 
t.get(0).getAttributeIs("class", "tree-junction-expanded"));
}


Please see TagTester.createTagsByAttribute for concrete parameters required.

Maybe someone else has a better approach. But for me this was working.

Hth
Mike

Wicket Basics.

[Shunmuga Raj]

Hi Per Newgro,

  Thanks for your valuable information.  I dont
know wicket basics also. If u have any tuorials or tutorial links
means pls send me. I downloaded some files for netbeans plugin from
IDE Plugins link.  But i dont know how to install it. Do you small
program to understand the wicket easily. If so means, pls send those
things to these id's.

Thanks in advance

Re: Strange error

[Martin Makundi]

I believe there are numerous such Maps, but what can be the cause of
concurrent modification? Wicket should be allowing only single thread
operating on the object?
