Re: AjaxEventBehavior called twice because of javascript onchange

[sauli.ketola]

Hi,

Could you instead use this:

See
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/markup/html/form/AbstractSingleSelectChoice.html#setNullValid%28boolean%29

If set to false, then Choose One will be displayed when the value is
null. After a value is selected, and that change is propagated to the
underlying model, the user will no longer see the Choose One option

With that, after you post the form the Choose One is removed. Or you could
save the value to the model of the dropdown inside the onchange behavior,
and the add the dropdown to the AjaxRequestTarget causing the dropdown to
refresh and the Choose One to be removed.


- Sauli

Re: How to null-check manually converted TextField values?

[Fred!!!]

Hi,

an other solution is to add a NullAcceptingValidator to your Textfield. 
Thus wicket will pass to IValidator.validate(IValidatable)


See 
http://ci.apache.org/projects/wicket/apidocs/6.0.x/org/apache/wicket/validation/INullAcceptingValidator.html

Re: Test Select2Choice with WicketTester

[Ulf Gitschthaler]

In most cases I want to simulate a user typing something in and selecting one 
of the offered choices. Afterwards I'd also like to submit the form and check 
if the model object of the Select2Choice field contains the right value, 
respectively I want to be able to submit the form if a Select2Choice field is a 
required field. 

Up to now it always failes because the model object is null. Just a simple 
example test case would be nice that shows how to test Select2Choice fields in 
a form.

Thanks Fred, that's what I found yesterday night after hours of

DropDownChoice not updating model

[Lucio Crusca]

Hello *,

I have a FormComponentPanel derived class that uses a DropDownChoice with a 
ChoiceRenderer. The DropDownChoice id matches the field name in my model class 
and I use a CompountPropertyModel wrapping my model instance for the 
component.

Code snippets:

class StreetAddress
...
  private String address;
  @ManyToOne
  private District idDistrict;

... usual getters and setters


class StreetAddressFormCP extends FormComponentPanelStreetAddress
...
  super(myCompountPropertyModel));
  add(new TextField(address));
  add(new DropDownChoice(idDistrict, ...));

class StreetAddressForm extends FormStreetAddress
...
  super(myCompoundPropertyModel);
  add(new StreetAddressFormCP(myCompoundPropertyModel));
 ...


All seems to work except that when I edit an address and change district in 
the dropdown, my onSubmit receives a model with the old value for idDistrict 
(but new edited value for address), so that part of the edit is lost. 

Isn't DropDownChoice supposed to always update the model when the user selects 
an item/submits the form?

P.S. onSubmit overridden on a Button behaves like stated above, while onSubmit 
overridden on the Form behaves differently: it receives a model with a null 
target...

Re: DropDownChoice not updating model

[Sven Meier]

If you use objects without overriden #equals() and #hashcode() and 
DropDownChoice you have several options:

1) use a custom ChoiceRenderer
2) override AbstractSingleSelectChoice#getModelValue()
3) make sure the selected choice is the identical object contained in 
the choices list (e.g. via OpenSessionInView)


https://issues.apache.org/jira/browse/WICKET-4353 might give you more 
information.

 For this it uses ChoiceProvider. So, you could test user typing directly
 using ChoiceProvider or for instance
 
 https://github.com/reiern70/wicket-select2/blob/master/wicket-select2/src/main/java/com/vaynberg/wicket/select2/AbstractSelect2Choice.java#L235
 
 to test produced JSON. (This is not part of offcial select2 but it is a
 pending pull request). Maybe I can factor out this a bit more and add a
 method that receives int page and String term so that testing is even
 easier.
 
 2-On client side widget uses a hidden input to represent selections as
 
 input id=what-input class=round-3-nopad type=hidden name=categories
 value=2,4 style=display: none;
 
 Those selected values are initially  assigned via JSON when widget is
 constructed.  See method
 
 https://github.com/reiern70/wicket-select2/blob/master/wicket-select2/src/main/java/com/vaynberg/wicket/select2/Select2MultiChoice.java#L114
 
 So one way... to simulate this might be as in
 
 TestMultiSelectPage testPage =tester.startPage(TestMultiSelectPage.class);
 tester.assertRenderedPage(TestMultiSelectPage.class);
 tester.getRequest().setParameter(countries, Country.CU.name()+,+
 Country.CA.name());
 tester.submitForm(testPage.getForm());
 Assert.assertTrue(testPage.getCountries().contains(Country.CU));
 Assert.assertTrue(testPage.getCountries().contains(Country.CA));
 Assert.assertTrue(!testPage.getCountries().contains(Country.US));
 
 So, you simulate client side working by passing a parameter with the
 selected choices.
 
 See
 
 https://github.com/reiern70/wicket-select2/blob/master/wicket-select2-examples/src/test/java/com/vaynberg/wicket/select2/SelectTest.java

Redirect to the HomePage on newSession

[vov]

Is it possible to redirect user to the HomePage when new session is created?

@Override
  public Session newSession(Request request, Response response)
{

//RequestCycle.get().setResponsePage(getHomePage());
//or 
//RequestCycle.get().replaceAllRequestHandlers(new
RenderPageRequestHandler(new //PageProvider(getHomePage(;
// do not work
}

The main idea is always show HomePage when user logged in to the application
and not take into account the URL which was printed to the address line

Behavior.renderHead stopped working after migration from 1.4 to 6.5

[Artur]

Hi Guys,

We just migrated our code to W6.5 and are very happy about it.
Unfortunately we don't know how to fix one of the errors.

We did a research but cannot find a solution :(

The code adds a link before a component with some javascript:

private class ChangeDateBehavior extends Behavior {
  [...]
@Override
public void renderHead(Component component, 
IHeaderResponse response) {
if 
(RequestCycle.get().find(AjaxRequestTarget.class) != null) {
String javascript = var e = Wicket.$(' + 
getMarkupId()
+ '); if (e != null  
typeof(e.parentNode) != 'undefined') e.parentNode.removeChild(e);;

response.render(JavaScriptHeaderItem.forScript(javascript, null));
}
String tag = a id=\ + getMarkupId() + 
\href=\#\ onclick=\changeDate(' + component.getMarkupId()
+ ',  + Integer.toString(days) + )\ + txt 
+ ;

response.render(JavaScriptHeaderItem.forScript(tag, null));

}

@Override
public void bind(Component component) {
this.component = component;
}

public String getMarkupId() {
return component.getMarkupId() + -- + id;
}

}


And the error msg from the console:
ERROR: Wicket.Head.Contributor.processScript: SyntaxError: syntax error: 
eval - a id=from2059--lthref=# onclick=changeDate('from2059', 
-1)\/a



Thanks for help in advance,
Artur

Re: Redirect to the HomePage on newSession

[Andrea Del Bene]

Hi,

try using  session listener interface ISessionListener. This entity 
defines method onCreated called after a new session ahas been created. 
To register a custom session listener use the following code in 
application class:


public void init(){
super.init();
ISessionListener myListener;
//listener initialization...
getSessionListeners().add(myListener);
}



Is it possible to redirect user to the HomePage when new session is created?

@Override
   public Session newSession(Request request, Response response)
{

//RequestCycle.get().setResponsePage(getHomePage());
//or
//RequestCycle.get().replaceAllRequestHandlers(new
RenderPageRequestHandler(new //PageProvider(getHomePage(;
// do not work
}

The main idea is always show HomePage when user logged in to the application
and not take into account the URL which was printed to the address line

Forward request to an external filter

[Leonid Bogdanov]

Hello!

  I'm trying to add OAuth authentication to a Wicket webapp and as a part of 
this I need to be able to do server-side forward of a request from Wicket to an 
external filter.
  So what is the best way to do this in Wicket? Do I need to throw some special 
exception with an URL to forward to or should do this more traditionally with 
RequestDispatcher.forward()?

Thank you.

Re: HttpsMapper with Apache Virtual Host Appending the Wrong Path

[Tim Urberg]

One last time, I found a bug in the code I had below, here's the fixed 
version:


@Override
protected String createRedirectUrl(IRequestHandler handler, Request 
request, Scheme scheme)

{
HttpServletRequest req = (HttpServletRequest) ((WebRequest) 
request).getContainerRequest();

String weblogicPrepend = req.getHeader(WL_PATH_PREPEND);
String requestUri = req.getRequestURI();
String url = scheme.urlName() + ://;

url += req.getServerName();

if (!scheme.usesStandardPort(getConfig()))
url += : + scheme.getPort(getConfig());

url += StringUtils.remove(requestUri, weblogicPrepend);

if (req.getQueryString() != null)
url += ? + req.getQueryString();

return url;
}

It does the same thing, checks the context path.  It would be nice if 
createRedirectUrl had separate methods for each part of the URL so 
those could be overridden individually since I basically copied and 
pasted the code from the original method only changing the request URI 
part.

I found a solution and it's not bad at all.  This works specifically 
with WebLogic and the HTTP WebLogic Plugin, so anyone using that 
setup should benefit from this:


1. I created a subclass of 
org.apache.wicket.protocol.http.servlet.ServletWebRequest to override 
getContextPath():


@Override
public String getContextPath()
{
String webLogicPrepend = getHeader(WL-PATH-PREPEND);
String contextPath = super.getContextPath();

if (StringUtils.equals(webLogicPrepend, contextPath))
return StringUtils.EMPTY;
else
return contextPath;
}

The WebLogic HTTP plugin sends a header called WL-PATH-PREPEND which 
is part of the Apache configuration (see 
http://docs.oracle.com/cd/E13222_01/wls/docs81/plugins/apache.html). 
I simply check to see if this header was sent and if it matches the 
one from the servlet.  If that's the case, I send an empty string 
back so it doesn't get added.


2. Override newWebRequest in the WebApplication to use the 
ServletWebRequest subclass:


@Override
public WebRequest newWebRequest(HttpServletRequest 
servletRequest, String filterPath)

{
return new ApiServletWebRequest(servletRequest, filterPath);
}

So far in my testing, I haven't had any of the problems I had 
before.  This solution may also work with mod_proxy, but I'm not sure 
if there are headers sent in that situation.


I created a bug (https://issues.apache.org/jira/browse/WICKET-5000) 
which could possibly be closed now that I've found this work around.

First the good news, I was able to get it to work by deploying the 
application in the root context. Once I did that, everything worked 
the way it should, paged switched from http to https with no

I've tried overriding createRedirectUrl to strip out the context in 
the url in HttpsMapper, but that only works part of the time.  For 
example, when I put the @RequireHttps annotation on a page, and have 
logged in, when I click a link to it /documentation is added to the 
URL, which tells me it's more of a problem than just HttpsMapper. 
Perhaps it's a problem with the delegate mapper as well.  The fact 
that it works correctly when deployed as the root context tells me 
there's got to be a better way to fix it. Anyway, I was wondering if 
anyone had any ideas as to where to start looking.  It would be nice 
if there was a way to tell the wicket application that even though 
I'm deployed at '/myapp', I'm actually behind a proxy and my context 
is '/'  That would really solve the problem.


I was thinking of creating a JIRA ticket or feature request for this.

Any thoughts?

You are of course right.

Yes, I know that is not a valid javascript but it was working somehow in 
previous releases :)
And I know that wicket execute eval on this. And this is why there is an 
error.


What I want to achieve?

I want to add html link before some wicket component.
And when clicking on that link I want to call javascript function to 
modify the text value of the component

without request to the server.

So the question is how to properly add this html snipped to the page.


Thanks for help,

6.0 Migration issue: wrap Wicket Ajax JS-code as previously with AjaxCallDecorators

[Martin Dietze]

In the project I'm currently migrating from Wicket 1.4 to 6.6 I have a few 
pieces
of code where AjaxCallDecorator instances would wrap the Wicket-genrated JS code
as shown in this little example:

| return new AjaxCallDecorator() {
| 
| @Override
| public CharSequence decorateScript( final CharSequence script ) {
| 
|   return var field = findField(); var result = findResult(); //
|   + if (field.val().length  3) { //
|   + renderInvisible() //
|   + } else { //
|   + $.throttle( getTimeout(), new function() {  + script + 
 }); //
|   + };
| }
| };

The problem I'm having here is that `$.throttle()' expects the actual script 
code as
a function, which it then calls according to the set timeout.

To me it seems like this is not possible with the APIs provided by Wicket 6.0, 
since
I can add code to be executed before and after the Wicket-generated code 
respecitvely,
but not *around* it. Maybe I haven't fully understood it and there actually is 
a way
to implement similar functionality?

I am rather unfamiliar with Javascript in general, maybe there's a better and 
easier way to port the above code to Wicket 6.0? 

As always grateful for any hint!

Re: 6.0 Migration issue: wrap Wicket Ajax JS-code as previously with AjaxCallDecorators

[Fred!!!]

Hi Martin,

it's possible to set an throtteling delay by Wicket 
AjaxRequestAttributes. Have a look at 
https://cwiki.apache.org/confluence/display/WICKET/Wicket+Ajax#WicketAjax-AjaxRequestAttributes


Something like this:
new AjaxEventBehavior(onkeydown){
   void updateAjaxAttributes(AjaxRequestAttributes attr)
   {
  attributes.setThrottlingSettings(new ThrottlingSettings(id, 
delay))

   }
}

Le 14 févr. 2013 à 00:39, Evan Sable e...@novelution.com a écrit :

 Hi,
 
 I'm working on a project that's on wicket 1.4.  It's using
 the MultiFileUploadField class.  I see in the code for that class that in
 renderHead, it calls:
 response.renderJavascriptReference(JS);
 and earlier it defines:
 private static final ResourceReference JS = new JavascriptResourceReference(
 MultiFileUploadField.class, MultiFileUploadField.js);
 
 But, I'd like to make a minor modification to the actual javascript in
 MultiFileUploadField.js.  Specifically, I want to modify that code to
 remove the c:/fakepath prefix that appears in the box with the list of
 selected files below the field (in chrome and safari - not a problem in
 firefox and ie).  If I could just over-ride the javascript contents of that
 file, it would be an easy fix.  But, more generally, I'd like to know not
 just for this specific issue, is there a wicket way to override the
 packaged javascript resource that comes with a component?  Perhaps is there
 a simple way to extend the MultiFileUploadField class with my own class,
 and somehow keep the rest of the code as is, but specify an alternate
 resource?  It's private in that class, so I don't see how I'd do this, but
 maybe I'm missing something obvious.  Or maybe is there some way to keep
 using the same class but to tell the application that I want to replace the
 corresponding javascript file with my own?  Or is there some other approach
 I should be taking when this type of issue comes up?
 
 Thanks very much for any advice,

Several Form onSubmit, is it possible add via AbstractBehavior?

[Alex]

Hi. I have AjaxFallbackButton on the form with defined onSubmit handler.
There also one custom AbstractBehavior added  to the form. This Behavior
does some action with form's components (add event handlers for form's text
controls) and next should intercept form's onSubmit event to do some action
also. I try do this by adding form.AjaxFormSubmitBehavior(form, onsubmit)
in this  AbstractBehavior (do this by override the onConfigure). As a result
only AjaxFormSubmitBehavior.onSubmit handler of MyCustomBehavior invoked but
form button's onSubmit is ignored. What is wrong in this case? Is it
possible to add additional onSubmit action to the form via custom Behavior
like in my case? 
Thanks for advice.

..
form.add(new AjaxFallbackButton(submit,form) {
   protected void onSubmit(AjaxRequestTarget target, Form?
aForm) {
  // some mail form submit actions
   }
 });

form.add(new MyCustomBehavior(feedbackPanel));
..

public class MyCustomBehavior extends AbstractBehavior {
   private FeedbackPanel feedback;
   private Form form;

   public MyCustomBehavior(FeedbackPanel feedback) {
 this.feedback = feedback;
   }

   @Override
public void bind(Component component)  {
  super.bind(component)
  // here initialize form 
  this.form = (Form) component;
}

   @Override
public void onConfigure(Component component) {
// here form's text controls event handlers added via
AjaxFormComponentUpdationBehavior
this.form.add(new AjaxFormSubmitBehavior(this.form, onsubmit)
{
@Override
protected void onSubmit(AjaxRequestTarget target) {
   // form submit action, set flag of some
operation
   // this onSubmit handler should be invoked
after main form onSubmit handler
} 
@Override
protected void onError(AjaxRequestTarget target) {
}
}
}
}

Re: Redirect to the HomePage on newSession

[vov]

Hi, 

unfortunately it does not help. Use session listener roughly the same with
using newSession method.

I found one solution but looks like workaround without a real needed.

1) throw CustomExceprion on the onCreated method of the ISessionListener.
2) Replace DefaultExceptionMapperProvider with CustomExceptionMapperProvider
@Override
  public IExceptionMapper get()
  {
return new IExceptionMapper()
{
  @Override
  public IRequestHandler map(Exception e)
  {
if (e instanceof CustomExceprion )
{
  return new RenderPageRequestHandler(new
PageProvider(Application.get().getHomePage()));
}
  }
};
  }

Does anybody know better solution?
