Re: How to remove panel in a list?

[vineet semwal]

Hi,

1)use dataview +reuseifmodelsequalstrategy
2) model object should be your data object and not component,
see examples  in the wicket distribution.

Re: AbstractAjaxTimerBehavior Problem

[Ernesto Reinaldo Barreiro]

Hi,

Ajax request are queued so if you do

while (true) {
//
}


then this thread will be locked till you get a time out... Maybe what you
want is

1- Create some "context" for monitoring progress
2- On onclick start a new thread and pass it context in 1). This thread
will increase progress in background.
3- Timer will also have access to context and update progress according to
it.

Request scoped variables, in ajaxrequesttarget

[Oscar Besga Arcauz]

 Hi wickers !

I was wondering If there's any method to have request-scoped variables ( as 
HttpServletRequest.get/setAttributes )
Specially with AjaxRequestTarget, in AJAX calls. 

I'm  using my own events within ajax calls. I know that an ajax call fires  an 
event into every component of a application; and I'd like to use this  event 
and avoid sending a second custom event.
Because of that, I want to attach some data to the request - to the 
AjaxRequestTarget maybe.


For  I've read in the forum, the way to do it could be a transient variable  
into the page which is nullyfied on the onDetach method.
But I find it not very elegant

Any ideas ?

Thanks


> > > Oscar Besga Arcauz  < < < 


PS.  I'm supposing that a ajax event called over one page of one user  
(session) is not propaged over other pages and other users (sessions)

We are having problems on Wicket 1.4.x with and "AJAX function"

let's bring the subject to the list...

Our problem is that after evaluating some expressions with errors, screen
"freezes" because post-call handlers are not called. Problem seems to be
related to the code.

 // test if the javascript is in form of

var res = text.match(new

if (res !== null) {
var f = jQuery.noop;
text = "f = function(" + res[1] + ") {" + res[2] + "};";

try {
// do the evaluation
eval(text);
  f(notify);
} catch (exception) {
Wicket.Log.error("Wicket.Ajax.Call.processEvaluation: Exception evaluating
javascript: " + exception + ", text: " + text);
  }

}


Questions:

1- Shouldn't

text = "f = function(" + res[1] + ") {" + res[2] + "};";

be

text = "f = function(" + res[1] + ") {" + res[2] + ";" + res[1]+"();"
+"};";

so that f(notify) ==> notify() gets called?

2- In case of error. Shouldn't it be

   try {

  eval(text);
f(notify);
} catch (exception) {
  Wicket.Log.error("Wicket.Ajax.Call.processEvaluation: Exception

 notify();
}


This I think is an error... as if eval fails... processing should continue.

So that next steps in processing get called. The above solves or freezing

Can someone shed some light on the above?

Yes I know 1.4.x is frozen... Fixing that on 6.x (and 1.5.x) will be more
than enough.

We will back-port solution to our local 1.4.x branch: in fact, we already
patched it for that problem but I wanted to be sure I was not wrong... and
also that we do not encounter the same problem if we migrate to a newer
version;-)

Migration issue: code using MarkupStream.findCOmponentINdex

[Martin Dietze]

I am currently migrating a project based on Wicket 1.4 to 6.60. 
At some point in that project we have this code:

| class Foo extends Panel {
| // ...
| private boolean hasFragment( final String fragmentId, final MarkupStream 
markupStream ) {
| final boolean found = markupStream.findComponentIndex( null, fragmentId ) 
>= 0;
| return found;
| }

This code is used to find if the markup stream for this component
contains the markup for a fragment with the given id. If found,
this markup is used for initialising an inner fragment class
with this markup.

Using a self-defined scheme for defining the Wicket markup ids,
this is used for allowing our HTML authors to define specialised
views for a group of model objects (e.g. a creature has a
generic view while cats and dogs have their own ones).

Now the findComponentIndex method has disappeared from
MarkupStream.

How can I do what I used to do in Wicket 6.60?

Cheers,

M'bert

Re: Request scoped variables, in ajaxrequesttarget

[Oscar Besga Arcauz]

Ok, it's a little complicated to create the metadata

If I'm rigth, the process is - for example when click on an AjaxLink into the 
page

1- Execute the method onClick of the AjaxLink
2- Send an event to all the components of the page (the page itself included, 
on first place, but not other pages ?),
   - The source of the event is the page itself
   - The type of broadcast is BREADTH 
   - The payload is the AjaxRequestTarget (from the onclick method call)

/ EXAMPLE OF DATA /
public class MyEventData {
    
    static  MetaDataKey METAKEY_MYEVENTDATA = new 
MetaDataKey(){}; 
    
    String s = "";

    public MyEventData(){}
    
    public MyEventData(String s) {
    this.s = s;
    }


    
    public MetaDataKey getWicketMetadataData(){
    // A little complicated
    MetaDataKey key = new MetaDataKey(){};
    MetaDataEntry metaDataEntry = new 
MetaDataEntry(key,this);
    MetaDataEntry[] arrayMetaDataEntry =  new 
MetaDataEntry[]{metaDataEntry};
    key.set(arrayMetaDataEntry,this);
    return key;
    }
    
    public void setIntoRequest(RequestCycle rc){
    rc.setMetaData(getWicketMetadataData(),this);
    }
    
    public static MyEventData getFromRequest(RequestCycle rc){
    return rc.getMetaData(METAKEY_MYEVENTDATA);

FormComponentPanel.convertInput()

[Richard W. Adams]

I'm writing my first FormComponentPanel, and have a couple of books 
showing how to do this. Most of it seems straightforward, except one 
point: In the books' examples, FormComopnentPanel.convertInput() creates a 
new model object and populates it from a series of calls to 
getConvertedInput() on the panel fields. The examples then call 
setConvertedInput() to store the newly populated model object.

The part I don't understand is this: Why create a NEW model object? Why 
not just call getModelObject() to get the ORIGINAL model, and populate IT 
with the new values? That would avoid the caller having to call 
getConvertedInput() on the panel component: The ORIGINAL model would be 
"magically" updated with the user-entered values when the form is 
submitted. That requires less work on the caller's part, and (IMHO) seems 
more consistent with the way other  property model paradigms work  in 
Wicket. (This, of  course, assumes the original model is mutable, which 
mine is.)

Anyone have any thoughts on the pros & cons of these two approaches?

why do you need to fire a custom event? Can't you just use AJAX event

Re: Request scoped variables, in ajaxrequesttarget

[Bas Gooren]

Well, it's a lot simpler than that.

Simply call rc.setMetaData( METAKEY_MYEVENTDATA, this );

Wicket handles the actual storage details (like storing your data in a 
MetaDataEntry array etc).

Nothing you need to think about :-)

Met vriendelijke groet,
Kind regards,

Re: FormComponentPanel.convertInput()

[Sven Meier]

Hi,

#convertInput() should not modify the current model object, because form 
submission might still fail with a conversion error on another field.


Pushing the new input in the FormComponent's model is done later in 
#updateModel().


Hope this helps

I'm writing my first FormComponentPanel, and have a couple of books
showing how to do this. Most of it seems straightforward, except one
point: In the books' examples, FormComopnentPanel.convertInput() creates a
new model object and populates it from a series of calls to
getConvertedInput() on the panel fields. The examples then call
setConvertedInput() to store the newly populated model object.

The part I don't understand is this: Why create a NEW model object? Why
not just call getModelObject() to get the ORIGINAL model, and populate IT
with the new values? That would avoid the caller having to call
getConvertedInput() on the panel component: The ORIGINAL model would be
"magically" updated with the user-entered values when the form is
submitted. That requires less work on the caller's part, and (IMHO) seems
more consistent with the way other  property model paradigms work  in
Wicket. (This, of  course, assumes the original model is mutable, which
mine is.)

Anyone have any thoughts on the pros & cons of these two approaches?

Well, it's a lot simpler than that.

Simply call rc.setMetaData( METAKEY_MYEVENTDATA, this );

Wicket handles the actual storage details (like storing your data in a 
MetaDataEntry array etc).
Nothing you need to think about :-)

AjaxLazyLoadingPanel or write your own async models.

Look back at the recent mailing list history - someone kindly posted an
example application utilizing various async loading techniques.

This would be a good topic for the new ref docs!

Re: a "loading ..." something ...

[Andrea Del Bene]

If you are using Wicket 6.x you can take a look at my project hosted at 
https://github.com/bitstorm/Wicket-tutorial-examples/tree/master/CustomAjaxListenerExample. 
There you can find a custom Ajax listener that displays a custom 
activity indicator for the whole duration of an Ajax request

There are some pages in my app that load slowly due to the amount of data the
customer needs to have (we have already optimized the retrieval part as much
as possible). So I thought it would be nice to have a "Loading ..." dialog
or something that disappears as soon as the data on the page have finished
loading.
What would you recommend for a Wicket app ? Any examples I could look at ?
Thank you !

AjaxEventBehavior called twice because of javascript onchange

[divad91]

Hi,

I using wicket 1.4.21 and developing an application that needs to work in
IE7 and +., firefox, chrome etc.

I have a problem with IE. Ajax "listener" are called twice because I have
javascript that remove the dropdown default empty option "Choose One".

My ajax listener is called on first time and then the javascript is removing
the default option causing my Ajax listener being called again.

This problems occurs only in IE.
This is not really related to wicket but I was wondering if anyone had this
problems before.

 ** My clients want the "Choose One" option so I can't just put a default
value to the drop down.

Thanks for help.

your code didn't come through with you initial post.

Regretfully I don't have an idea what's going wrong here: Removing an

Re: HttpsMapper with Apache Virtual Host Appending the Wrong Path

[Tim Urberg]

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

The bad news is that deploying it as / not an option.  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?

Ok, I'm making *some* progress (if you can call it that).  First of 
all, here's more about my setup.  I'm using wicket-auth-roles for 
authentication and I have this set up in my WebApplication.class 
based on an example I found in wicket examples:


1) the authorization strategy
getSecuritySettings().setAuthorizationStrategy(new 
IAuthorizationStrategy()

{

@Override
public  boolean 
isInstantiationAuthorized(Class componentClass)

{
if (AuthenticatedWebPage.class.isAssignableFrom(componentClass))
{
if (ApiAuthenticatedWebSession.get().isSignedIn())
return true;

throw new RestartResponseAtInterceptPageException(new 
LoginPage());

}
return true;
}

@Override
public boolean isActionAuthorized(Component component, Action 
action)

{
return true;
}
});

2) I have every page needing login.
3) I've got the login page mounted as /login and @RequireHttps on it.
4) In the onsubmit of the the login form I'm calling 
continueToOriginalDestination();


That's my setup, My attempt was to override createRedirectUrl in 
HttpsMapper so that it looks like this:


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

{
return StringUtils.remove(super.createRedirectUrl(handler, 
request, scheme), "/documentation");

}

This works as long as I go to http://myserver.com/login and it will 
correctly redirect to https://myserver.com/login rather than 
https://myserver.com/documentation/login like it did before. However, 
if I go to http://myserver.com/ (the home page which redirects to the 
login page as part of the authorization strategy) it goes to 
https://myserver.com/documentation/login. Also if I go straight to 
the login page, login successfully, it will redirect to 
http://myserver.com/documentation what it thinks is the home page.


I looked at the code in RestartResponseAtInterceptPageException and 
I'm thinking this code could be the culprit:


static void continueToOriginalDestination()
{
InterceptData data = InterceptData.get();
if (data != null)
{
data.continueOk = tr

Multipart ajax form submit channel

[Ashley Reed]

I just wanted to ask this question before figuring out how to file a 
bug. I'm using Wicket 1.5.6, and it seems like multipart ajax form 
submits don't block the ajax channel. I'm doing an ajax submit that 
causes the form to go away, and other ajax links on the form don't wait 
until the form submission is complete. The result is that other ajax 
links cause an exception if they're clicked before the form submission 
is complete because the objects no longer exist in the page. I would 
think the precondition on the links shouldn't be tested until the 
channel is available. Is this a bug?


Thanks,
Ashley

changing pdf content in Iframe , on "item select" event

[mayanksahai]

hi all,

i am new to wicket and trying to build a page that contains a "drop down",
listing all the documents associated to a user. i have a "div"on the same
page that encapsulates an "Iframe" , where document content is displayed.

a user can change "document" in dropdown and once item is selected , that
should get displayed in underlying "iframe". i do not know the appropriate
way of doing this.

since document can be anything image/excel/pdf , i need a holistic approach
to render any kind of content in iframe.

i tried intercepting the "On selected" event of dropdown choice and
manipulate the "src" attribute of iframe but it is not working.

can someone point me to any example etc.

thanks

mayank sahai

How to null-check manually converted TextField values?

[Sebastian Gaul]

I have a TextField which overrides it's getConverter method to add a
Joda time converter instead:

new TextField(id) {
@Override
public  IConverter getConverter(Class type) {
return (IConverter) new JodaDateTimeConverter();
}
};

The converter returns null if input was invalid. However, I want to be
able to flag this field as required, and I don't know how to do that:

 - textField.isRequired(true) does not work, because required checks
are done before conversion. This doesn't work for non-empty but
invalid inputs.

 - textField.add(.. some validator ..) does not work because no
validator is called if the converter returned null.

I really don't see an approach to flag my date fields as required. Do
you know how to do that? Probably my approach is not suited at all?

how to modify internal JavascriptResourceReference packaged with component

[Evan Sable]

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,
-Evan

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

[Sebastien]

Hi,

Well, the required flag ensures that the input is not empty, not that it is
of the correct type...

If the conversion fails, is it supposed (I guessed) to throw a
ConversionException.
As it seems to not be the case, I would have overridden convert input as
follow (not tested):

class MyJodaDateTextField
{
   protected void convertInput()
   {
super.convertInput();

Date value = this.getConvertedInput();

if (value == null)
{
//handles the error message
ValidationError error = new ValidationError();
error.addKey("MyJodaDateTextField.ConversionError"); //wicket6
//error.addMessageKey("MyJodaDateTextField.ConversionError");
//wicket1.5
error.setVariable("date", value);
this.error(error);
 }
}
}

MyJodaDateTextField.properties will contain:
MyJodaDateTextField.ConversionError='${date}' is not a valid Joda datetime

Also pay attention to check the type in getConverter

{
if (Date.class.isAssignableFrom(type))
{
return (IConverter)new JodaDateTimeConverter();
}

return super.getConverter(type);
}


Hope this helps,
Sebastien.

Re: HttpsMapper with Apache Virtual Host Appending the Wrong Path

[Tim Urberg]

One more thing, I needed to override createRedirectUrl in HttpsMapper to 
look like this:


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

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

String url = scheme.urlName() + "://";
url += req.getServerName();
if (!scheme.usesStandardPort(getConfig()))
{
url += ":" + scheme.getPort(getConfig());
}

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 
problem.  The bad news is that deploying it as / not an option.  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?

Ok, I'm making *some* progress (if you can call it that).  First of 
all, here's more about my setup. I'm using wicket-auth-roles for 
authentication and I have this set up in my WebApplication.class 
based on an example I found in wicket examples:


1) the authorization strategy
getSecuritySettings().setAuthorizationStrategy(new 
IAuthorizationStrategy()

{

@Override
public  boolean 
isInstantiationAuthorized(Class componentClass)

{
if 
(AuthenticatedWebPage.class.isAssignableFrom(componentClass))

{
if (ApiAuthenticatedWebSession.get().isSignedIn())
return true;

throw new RestartResponseAtInterceptPageException(new 
LoginPage());

}
return true;
}

@Override
public boolean isActionAuthorized(Component component, Action 
action)

{
return true;
}
});

2) I have every page needing login.
3) I've got the login page mounted as /login and @RequireHttps on it.
4) In the onsubmit of the the login form I'm calling 
continueToOriginalDestination();


That's my setup, My attempt was to override createRedirectUrl in 
HttpsMapper so that it looks like this:


@Override
protected String createRedirect

Hi,

Maybe you can adapt

to your needs?
