markup not found exception for fragment which is part of wicket:extend

[Rakesh A]

Hi,

I am using Wicket v6.5.0, I've code where wicket fragments are part of
'' tag and I get exception that Markup is not found for the
fragment, same piece of code works in Wicket v1.4.21.

I created & attached a quick start with code similar to my case.

fragmentTest.zip
  

Regards,
Rakesh.A

ConfirmAjaxFallbackLink with LoadableDetachableModel

[Vignesh Palanisamy]

Hi all,

I have  a ConfirmAjaxFallbackLink which is use to display confirmation
dialog, when a user attempts to delete an item in a datatable.

public abstract class ConfirmAjaxFallbackLink extends AjaxFallbackLink
{
private String confirmMessage;
private IModel confirmMessageModel;


public ConfirmAjaxFallbackLink(String id, String confirmMessage)
{
super(id);
this.confirmMessage = confirmMessage;
}

public ConfirmAjaxFallbackLink(String id, IModel messageModel)
{
super(id, messageModel);
this.confirmMessageModel = messageModel;
}

@Override
protected void updateAjaxAttributes(AjaxRequestAttributes attributes)
{
super.updateAjaxAttributes(attributes);
AjaxCallListener ajaxCallListener = new AjaxCallListener();
if (confirmMessage != null) {
ajaxCallListener.onPrecondition(new
JavaScriptEventConfirmation(confirmMessage).getBeforeHandler(this));
} else {
ajaxCallListener.onPrecondition(new
JavaScriptEventConfirmation(confirmMessageModel.getObject()).getBeforeHandler(this));
}
attributes.getAjaxCallListeners().add(ajaxCallListener);
}

@Override
public abstract void onClick(AjaxRequestTarget target);
}



it works fine with static message and static model


but i want to load the message dynamically. so i use LoadableDetachableModel

like this

new ConfirmAjaxFallbackLink("deleteItemLink", new
LoadableDetachableModel()
{
@Override
protected String load()
{
List activeUsages =
findActiveUsages();
if (activeUsages.size() > 0) {
return "This item is actively used in "
+activeUsages +", Do you still want to delete it?";
}
return "Do you want delete?"
}
})
{
@Override
public void onClick(AjaxRequestTarget target)
{
onDelete(target);
}
};


But it doesn't load dynamically. while we refresh the page only it loading.


can you have any idea about it.



Thanks,
Vignesh

Re: Feedback message is not available for behaviors added to nested form components

[James Selvakumar]

Hi Jesse,

I was not aware of this before. Thanks for the insight
But I do add/remove components to the ListView dynamically.
Will ListView#setReuseItems(true) affect that?

 I've the following component heirarchy:

 form:textField

 form:submitButton

 I've marked the all the form components as required.

 I also have a behavior that is added to all the form components (via
 IVisitor) which will make the respective feedback messages appear under
 the
 form components.

 It works perfectly for the form component "texField" which is directly
 attached to the form.

 However it doesn't work for for "panel1DropDownChoice".

 I've added some debug messages in the "validate()" method of
 "panel1DropDownChoice" and found that feedback messages are indeed
 generated.

 However from the debug messages in my behavior, I found that feedback
 messages were some how lost.

 This is the behavior I'm using. (Thanks London Wicket users)

 *public class ValidationMsgBehavior extends Behavior

 {
   private static Logger logger =
 LoggerFactory.getLogger(ValidationMsgBehavior.class);


   @Override
   public void afterRender(Component c)
   {
   logger.debug("Preparing to add validation msg for the
 component
 {}", c);
   FormComponent fc = (FormComponent) c;
   if (!fc.isValid()) {
   String error;
   if (fc.hasFeedbackMessage()) {
   logger.debug("Form component {} has feedback
 messages",
 fc);
   error =
 fc.getFeedbackMessages().first(FeedbackMessage.ERROR).

 getMessage().toString();
   } else {
   error = "Your input is invalid.";
   }
   fc.getResponse().write(
   "" + error + "");
   }else{
   logger.debug("Form component {} is valid", fc);
   }
   }
 }*

 Any clues? I've been trying to crack this for a whole day.

Follow the path A AB ABB ABBA ABBB ABBBA ABC ABD AC in advanced nested

Re: How to call Java Function from JavaScript

[Bas Gooren]

Wicket's ajax functions require you to load the wicket ajax javascript.

This is handled by the AbstractDefaultAjaxBahavior out of the box.
However, since you do not call super.renderHead(component,response) in 
your code, the required javascript files are not loaded.

the dot is a leftover from the days when Wicket used '.' to separate

Still I can't understand the dot Vs/ column reason, but I guess I can consider

Re: Save place to set http response status?

[Martin Funk]

Besides the 'non' buffering trait of the BufferedWebResponse it is a little
irritating, that the 'setStatus(int)' method doesn't signal if its
execution is not successfull.

Though locking into code like: org.apache.catalina.connector.ResponseFacade
of Tomcat shows that it doesn't signal anything either.
[...]
public void setStatus(int sc) {

if (isCommitted())
return;

response.setStatus(sc);

}
[...]

even the JavaDoc of oracle isn't helpful:
http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpServletResponse.html#setStatus(int)
it only gives a statement on
http://docs.oracle.com/javaee/6/api/javax/servlet/ServletResponse.html#reset()
which should throw a IllegalStateException - if the response has already
been committed
http://docs.oracle.com/javaee/6/api/javax/servlet/ServletResponse.html#isCommitted()

If it were up to me, I'd of course would like to have both.
Wicket guaranteeing that the status can be set up till 'onDetach()'
and also a signal if setStatus was not successfull.
;-)

Re: cryptic error messages [SOLVED]

[Lucio Crusca]

I've found that between this line of code:
>RepeatingView rv = new RepeatingView("repeatingDocTypes");

and these ones:
>for (...)
>  addDocTypeBox(rv, docs);

I actually had an extra rv.newChildId() hidden in calls which obviously bumped 
the next id value...

Still I can't understand the dot Vs/ column reason, but I guess I can consider 
them equivalent, right?

cryptic error messages

[Lucio Crusca]

Hi *,

I have the following markup snippet:


  Orders
  
  

  


which is bound to this code snippet:

[...]
   RepeatingView rv = new RepeatingView("repeatingDocTypes");
   for (...)
 addDocTypeBox(rv, docs);


  private void addDocTypeBox(RepeatingView rv, List docs)
  {
AbstractItem i = new AbstractItem(rv.newChildId());
i.add(new Label("docTypeName", getDocTypeDescription());
RepeatingView rdr = new RepeatingView("repeatingDocRef");
i.add(rdr);

for (Document d: docs)
{
  AbstractItem docsummary = new AbstractItem(rdr.newChildId());
  Link l = new Link("doclink")
  {
 ...
  };
  docsummary.add(l);
  l.add(createSummaryPanel("docid", d));
  rdr.add(docsummary);
}

rv.add(i);
  }

Please note that the two for loops execute just 1 iteration each with my 
current test data.

I get the following exception:

Last cause: Unable to find component with id 'docTypeName' in [AbstractItem 
[Component id = 1]]
Expected: 'footerPanel:repeatingDocTypes:1.docTypeName'.
Found with similar names: 'footerPanel:repeatingDocTypes:2:docTypeName'

which does shed some light on what's going on, but I find it hard to understand 
what do "1.docTypeName" and "2:docTypeName" mean. Where did those "1" and "2" 
come from? What information do they give me in order to spot the bug? Why is 
"1" followed by a dot while "2" is followed by a column?

Strict date pattern for DateTextField in Wicket

[Jayakrishnan R]

Hi All,

I have a DateTextField component in my application and I want the input of
date using a predefined pattern. The pattern that I need is "-MM-dd". I
created the DateTextField using the following code.

DateTextField dtf_ExpiryDate =
DateTextField.forDatePattern("ExpDate", "-MM-dd");
dtf_ExpiryDate.add(new DatePicker());

It helps to prevent date input in most of other formats. But it accepts
input in dd-MM- format and converts it into some weird format. For
example, *12-06-2013* is automatically converted to *0012-06-20*.

Is there a way to throw an error when the date is given in dd-MM- ?

Javadocs of 
DateTextFieldsays
that the conversion is done internally using the Joda time parser. Is
there a way to add more constraints ?

I really don't want the data to be captured as String and add a
StringValidator to check if it confirms to the pattern using Regex.

Thank you

Predmet: RE: wickettester and wizard next step submit response

If you read the API docs for the FromTester you'll find out that you can only 
submit it once.
After that you need to grab a new FormTester and submit it again.

As such, on each step of your wizard you should create a new FormTester and 
submit it using the corresponding button, not invoking the Button.onSumit() but 
by calling gormTester.submit(myNextOrFinishButtonPath).

This is a small example on how I complete a wizard step:
private void completeUserGroupDetailsStep(ConsoleWicketTester tester) {
FormTester formTester = getHelper().getWizardFormTester(tester);
tester.setValue(formTester, tester.findComponent("**:name", 
TextField.class),   testUserGroup.getName());
tester.setValue(formTester, tester.findComponent("**:description",  
TextArea.class),testUserGroup.getDescription());
tester.submit(formTester, getHelper().getWizardNextButton(tester), 
false); // same as FormTester.submit()
tester.assertRenderedPage(EditUserGroupPage.class);
tester.assertNoErrorMessage();
tester.cleanupFeedbackMessages();
}

Where tester.submit takes in a reference to a FormTester and invokes its 
sumit() method after a bunch of asserts which I won't bore you with right now. 
However, I'll be nice and share my wizard helper methods to give you an idea :)

By default REDIRECT_TO_BUFFER strategy is used so all this happens in the
second http request cycle.
But for all other cases in WebPageRenderer you are right.

Yep. No buffering by Wicket, but still the flush is needed for the
buffering done by the servlet container.

 Wicket buffers the response so Tomcat cannot flush it no matter the
 size.
 I.e. the HttpServletResponse has no data to push until the very end of
 the
 request cycle.

Re: Save place to set http response status?

[Sven Meier]

Yes, WebPageRenderer renders the page into a BufferedWebResponse. But 
after that it writes it into the response of the RequestCycle:


response.writeTo((WebResponse)requestCycle.getResponse());

That's the point of no return.

By default the RequestCycle's response is a ServletWebResponse nested in 
a HeaderBufferingWebResponse. So only headers are buffered until the 
first content is written.


ServletWebResponse#flush() just forwards to 
HttpServletResponse#flushBuffer(), no buffering involved there.

Re: Feedback message is not available for behaviors added to nested form components

[Jesse Long]

Hi James,

This is a shortened list of events happening, including only the ones 
affecting you. They are in the order in which they occur.


 * IFormSubmitListener#onFormSubmitted()
 * ListView#onBeforeRender()
 * Page#onRender()

ListView#onBeforeRender() calls ListView#onPopulate(). If you are not 
using ListView#setReuseItems(true), then ListView#onPopulate() removes 
all children of ListView and re-creates them.


So, the children of ListView that are present during Page#onRender() are 
not the same children that were present during 
IFormSubmitListener#onFormSubmitted(), and hence not the same children 
that had the feedback messages.


Cheers,
Jesse

Hi all,

I've the following component heirarchy:

form:textField
form:listView:panel-1:**panel1DropDownChoice
form:submitButton

I've marked the all the form components as required.

I also have a behavior that is added to all the form components (via
IVisitor) which will make the respective feedback messages appear under
the
form components.

It works perfectly for the form component "texField" which is directly
attached to the form.

However it doesn't work for for "panel1DropDownChoice".

I've added some debug messages in the "validate()" method of
"panel1DropDownChoice" and found that feedback messages are indeed
generated.

However from the debug messages in my behavior, I found that feedback
messages were some how lost.

This is the behavior I'm using. (Thanks London Wicket users)

*public class ValidationMsgBehavior extends Behavior

{
  private static Logger logger =
LoggerFactory.getLogger(**ValidationMsgBehavior.class);

  @Override
  public void afterRender(Component c)

  }
  fc.getResponse().write(
  "" + error + "");
  }else{

Any clues? I've been trying to crack this for a whole day.

That's not quite right:
As soon as WebPageRenderer writes the buffered page into the real response,
