Re: Session timeout - AJAX-enabled controls

[David Matoušek]

It was happening to me on Wicket examples page too. Especially on 
AjaxFallbackDataTable Example. 

I just checked it but now it seems to be working correctly. What version 
of Wicket are examples on url:

http://www.wicket-library.com/wicket-examples/
running and were they changed lately?
I am using 1.3.6 so maybe it was fixed in 1.4.x versions.

David Matousek


I do not have that problem: if session expires any action the user does
triggering a server round trip, AJAX or not, on a protected page redirects
me to the login page... Can you post more details?

Best,

Ernesto

yes we also have this prob lem For example i use a wicket in
dicating ajax button in our logi n page. If thne user doesn t click a
link that moves a page he will not be able to k now that the session
has i ndeed expired. The screen o ly shows the rotating image  but
nothing happens.  but if i use a normal submit li nk, im immeddiately
redirected..
Some clients didnt mind it bbut some clients do

thanks

Hi,
I have a problem with ajax behavior, that i use to fill various


dropdowns


by
data from database.
When session expires(user was inactive), non-ajax controls correctly
redirect me to some kind of Error page. Thats correct.
Components that have defined ajax behavior to update another components
don't redirect, and doesn't update another components either.
Is that Wicket feature, or a bug? Can components with ajax behaviors be
forced to redirect to error page on session expire like non-ajax ones


do?


Any suggestions?

Thanks for reply

David Matousek

Re: CompoundPropertyModel

[Николай Кучумов]

Hello, Alex, Jeremy and others.

That's weird. Really weird.
You know what?
Seems that my browser was causing the error...
If i open my site via a bookmark, it outputs the error.
However if i open a new tab and type in the URL manually, the error doesn't
appear.
So, an advice to all of the Firefox users: don't bookmark the link to your
web application!

Re: JQuery slider implementation broken in 1.4?

problems with WicketTester and Scala

[Haim Ashkenazi]

Hi

I'm playing around with wicket/scala and I found some odd behavior with 
WicketTester.

The code is here:
http://github.com/babysnakes/comnshours
revision: 6196415aa5910d984dd582e7a6aa28017e6f0dbc

The specific test is here:
http://github.com/babysnakes/comnshours/blob/6196415aa5910d984dd582e7a6aa28017e6f0dbc/web/src/test/scala/test/components/TechTableComponents.scala

The first problem is in line 78. When running the server manually when I follow 
the same steps I do in the test the feedback panel is empty, but in the test 
(if I remove the skip) it will fail because the feedback is not empty.

The second problem is in line 120. The form (val b) should have a Technician 
object as it's ModelObject but b.getModelObject returns null.

In order to run the server (although it's not required for these tests), 
CouchDB is required to run on localhost.

Any ideas?

Bye

I have built a flash movie that get's data from a webservice. When trying to

How can I make this file viewable this way using wicket?

Re: request scoped variables

[Douglas Ferguson]

Yeah, but how to I guarantee that it will be detached and reloaded on every 
request.

Also, the application is already using the session as the factory for this 
loadable detachable.
Just out of curiosity, I cached it rather than always constructing a new one, 
and I started getting all sorts of errors. 

So then I started to think that perhaps I could try make sure that a new one is 
generated per request.
I tried using a thread local to hold the LDM on the session but that caused the 
same errors.

 The error seems to indicate that the a component is not on the page when

 The error is also intermittent.

Re: request scoped variables

[Martin Makundi]

Why should it be detached every request if it is lightweight?

It seems you have a problem elsewhere? Maybe you have problems with
object equalities etc?

YOu can override MySession.detach to detach it.

 you can have a transient field on the page that you null in ondetach()...

 otherwise you can access httpservletrequest and use attributes.

Re: request scoped variables

[Douglas Ferguson]

Good idea, I will double check the equals method.

The object is a hibernate pojo, which has to be detached because it can't be 
used after the hibernate session dies.
The hibernate session dies on every request.

 When a user logs in the userId is stored on the session.
 There is a method on the session object that returns a 
 UserAccountLoadableDetachable.
 This loadable detachable is created every time the method is called.

 My thought was that I could share it across the request.

Why not? I reuse the hibernate pojos throughout the whole user web session.

Wicket YUI - Integration (Slider Question)

[Corbin, James]

Hello,

 

I am using the framework off the wicket-stuff trunk that wraps yui to
work with wicket.  I must say it works pretty well.

 

I did have a few questions on the slider that I hoped someone had
experience with at solving,

 

1. I cannot seem to get the tick marks to show up on the control?  Is
this not supported in the current implementation of the framework
wrapper?

2. Does the slider component support attaching ajax behaviors?  I am
looking to bind an ajax behavior (onchange) that updates a label with a
current value of the slider.  I assume this is possible and will try it
this morning but wanted to check the forum to see if its wasted effort.

 

Thanks,
J.D.

Re: Flash and Wicket crossdomain.xml

[Jonas]

Is the content of you crossdomain.xml 'static'? If so, I guess
you can just put that file into your web app's context root.
If you need the file content generated dynamically, I doubt
generating it in wicket is the easiest way to do it. I think
I would rather just use a simple servlet.

RE: Wicket YUI - Integration (Slider Question)

[Corbin, James]

In regards to ajaxy question below, the reason I needed this was to
update a label when the slider value was changed.  I looked at the
example and noticed that this could be done by overriding the following
method on the slider:

Protected String getOnChangeJSFunc() {...} 

I still have the question on rendering the tick marks, but will continue
looking at that one as well.

Subject: Wicket YUI - Integration (Slider Question)

Hello,

 

I am using the framework off the wicket-stuff trunk that wraps yui to
work with wicket.  I must say it works pretty well.

 

I did have a few questions on the slider that I hoped someone had
experience with at solving,

 

1. I cannot seem to get the tick marks to show up on the control?  Is
this not supported in the current implementation of the framework
wrapper?

2. Does the slider component support attaching ajax behaviors?  I am
looking to bind an ajax behavior (onchange) that updates a label with a
current value of the slider.  I assume this is possible and will try it
this morning but wanted to check the forum to see if its wasted effort.

 

Thanks,
J.D.

Corrupt URL for shared resource

[Russell Morrisey]

We are getting erroneous requests in our access log, where a URL for a shared 
resource, which is supposed to look like:
com.mycompany.mywidgets.Widget/icon.gif

...instead looks like:
com.mycompany.m564ywidgets.Widget/icon.gif

These bad requests result in an application error like:

UploadWebRequest is actually a UploadWebRequest$MultipartRequest

[Wayne Pope]

Hello,

we get the following warning in our logs:
(UploadProgressBar.java:106) - UploadProgressBar will not work without
an UploadWebRequest. See the javadoc for details.

We do override in the application:
@Override
protected WebRequest
newWebRequest(javax.servlet.http.HttpServletRequest servletRequest) {
return new UploadWebRequest(servletRequest);
};


When I debug UploadProgressBar I see that:
if (!(RequestCycle.get().getRequest() instanceof UploadWebRequest))
{
log.warn("UploadProgressBar will not work without an
UploadWebRequest. See the javadoc for details.");
}

However RequestCycle.get().getRequest() is returning a
UploadWebRequest$MultipartRequest instance.

What are we doing wrong or is this a bug?

thanks

Passing models to panels - Couldn't resolve model type of Model

[Kogel, Jonck-van-der]

Hi,
I'm have a question about my application design and whether I should
pass a model to a panel or an id and create a new
LoadableDetachableModel in the panel. Here is a basic layout of my app:
 
I have taken out the non-relevant parts for brevity.
 
My domain model is basically as follows:
Base class is ARF. It has an owner, a keeper and a user. The owner,
keeper and user all have a correspondence address and a visiting
address.
 
The layout of my application reflects this. The main screen has 3 tabs,
one for owner, one for user and one for keeper. These tabs are panels. I
also defined one addressPanel to display all the addresses.
 
So when I am building my view, it is as follows:
 
On my page I create a LoadableDetachableModel as follows:
 
IModel arfModel = new LoadableDetachableModel() {
 @Override
 protected ARF load() {
  return arfService.load(arfId);
 }
}; 
 
I pass this model on to my tabs panel:
 
public class ArfPageTabsPanel extends Panel {
 public ArfPageTabsPanel(String id, IModel arfModel) {
  super(id);
  add(new TabOwner("tabOwner", arfModel));
  add(new TabKeeper("tabKeeper", arfModel));
  add(new TabUser("tabUser", arfModel));
 }
}
 
The TabOwner class is as follows:
 
public class TabOwner extends Panel {
 public TabOwner(String id, IModel arfModel) {
  super(id);
  
  add(new AddressPanel("correspondenceAddress", "Correspondentie-adres",
new PropertyModel(arfModel, "owner.correspondenceAddress")));
  add(new AddressPanel("visitingAddress", "Bezoekadres", new
PropertyModel(arfModel, "owner.visitingAddress")));
 }
}
 
the TabKeeper and TabUser classes are much the same as the TabOwner
class (probably I could do some code reuse here, I'll do that when
everything is working and I understand it all).
 
And then the AddressPanel is as follows:
 
public class AddressPanel extends Panel {
 public AddressPanel(String id, String addressHeader, IModel
addressModel) {
  super(id);
  add(new Label("addressHeader", addressHeader));
  add(new TextField("street", new
PropertyModel(addressModel, "street")));
  add(new TextField("houseNr", new
PropertyModel(addressModel, "houseNr")));
  add(new TextField("houseNrExt", new
PropertyModel(addressModel, "houseNrExt")));
  add(new TextField("zipcode", new
PropertyModel(addressModel, "zipcode")));
  add(new TextField("city", new
PropertyModel(addressModel, "city")));
 }
}
 
 
So I am nesting all my models here, since the underlying arfModel is a
LoadableDetachableModel and I don't want to get my panels and the main
view out of sync. The problem is however that sometimes there is no
owner/keeper/user and hence also no addresses for that relation. When I
do load an ARF that has a null keeper for example, my console is flooded
with the following message:
 
2009-11-20 17:42:02,274 WARN [AbstractTextComponent] Couldn't resolve
model type of
Model:classname=[org.apache.wicket.model.PropertyModel]:nestedModel=[Mod
el:classname=[org.apache.wicket.model.PropertyModel]:nestedModel=[Model:
classname=[com.bmw.preparer2.view.ArfPage$1]:attached=true:tempModelObje
ct=[com.bmw.preparer2.domain@d737e3]]:expression=[user.visitingAddre
ss]]:expression=[city] for [MarkupContainer [Component id = city]],
please set the type yourself.

 

I am assuming that this has to do with that I am nesting my models and
that one of them is null. So in the AddressPanel I am creating a
PropertyModel where the passed on model is potentially null.

So my question is, how do I handle such a situation? Please advise.

Thanks very much, Jonck van der Kogel

How can I disable a IFormValidator?

[Wayne Pope]

Hello,

I have a form that has a AbstractFormValidator added to it. This does
some validation on a couple of formcomponents.

However in some situations on of the components is not visible and we
get the warming:

IFormValidator in form `formContainer:form` depends on a component
that has been removed from the page or is no longer visible.

How can I diable the AbstractFormValidator so that we don't get this
warning? (as it doesn't need validating).

many thanks
Wayne

Posting A Form To NonWicket

[Balaji C]

I've a wicket form with input elements. I would like to post this form to a
non-wicket url. Is it possible to post this form from submit event of wicket
button? I google and couldn't find any clear solution. Any help is
appreciated. If any other alternative, please let me know. Thanks.

Re: Posting A Form To NonWicket

[Edward Zarecor]

Is there a requirement to process the data in any way before
submitting to the remote application?  Why wouldn't you just use an
HTML form with the appropriate action pointing to the remote host?
Wicket may not need to know about this form.

Ed.

You could write something on the server end (or your wicket app) that would
do it for you.
Just use apache http commons or write your own post code. Easy stuff (open
socket, couple commands, dump input, close socket).

It can even get back to the user with error codes from the other server etc
if you wanna be spiffy.

Resolving image locations

[Loritsch, Berin C.]

I'm using the Wicket Image object, and I'm having a hard time ensuring
that it resolves properly.

I have a base class to set up the UI template for the site, including
the logo image.  I added a new page in a child package, and as a result
the Image declared in the base class is resolving relative to the new
class.  This is counter-intuitive, and violates the expectations of
object oriented programming.  Here is the basic situation:

package.SiteTemplate

Declares Image(Logo)


package.images.Logo
---
Contains the image


package.subsystem.NewPage
-
Uses logo declared in SiteTemplate,
But browser can't find it



What I want to do is tell Wicket to always provide one path for the Logo
image, so I don't have to duplicate the logo in several packages.  I
attempted to hardcode the path in plain HTML, but that URL broke as soon
as the IDE put the app in a context.  I'd like Wicket to take care of
the base path, but not treat it like a resource that needs to be
internationalized.  How do I do that?

Re: Passing models to panels - Couldn't resolve model type of Model

[Igor Vaynberg]

hrm, we should change that message to info rather then warn, warn is a
little too strong.

the problem is that textfield tries to resolve what type of object it
is bound to (a string, an int, etc) but cant because the model object
is null.

you can silence the warning by explicitly setting a type on the textfield, eg

 add(new TextField("street", new
PropertyModel(addressModel, "street"), ***String.class***));

or, since you will get an NPE if you submit the form, a better way
would be to hide the form entirely

addresspanel { isvisible() { return getmodelobject()!=null; }}

Re: How can I disable a IFormValidator?

i dont think currently there is a way, please add an rfe.

as an alternative you can move your validation logic into

Never mind.  The problem was using Image instead of ContextImage.  I

Complications with loadable detachable models

[bht]

Hi

It appears that I am fighting against the framework that limits my
choices when I start using LDMs (LoadableDetachableModel).

Many examples in the framework documentation don't use LDMs. For
simplicity, they assume that the domain object e.g. person is
available to a model in an instance variable.

But LDM use is Wicket best practice. So if I switch to LDMs, then I
remove instance variables containing domain objects to avoid their
leakage into the session.

As a consequence of that, I must use wrapped PropertyModels that use
reflection and that are not refactor safe.

In addition, in onSubmit() methods, I have to manually extract the
domain object from the model.

If I use simple custom models per form field, overriding
org.apache.wicket.model.Model with inner classes, then I have to
manually extract the domain object from the LDM for each
setObject(...) and getObject() method.

To avoid these obstacles I would keep for convenience a transient
instance of the domain object. In onDetach(), I would set it to null
to avoid leakage into the session.

But how do I initialize it? I can do it in a Panel's constructor, but
in a stateful page, the constructor of a Panel is not called when it
is taken out of the session.

I found Page.onPageAttached() interesting for that, but I cannot use
it with a Panel sub class that is not hard-wired into the Page.

How can I use LDMs without this conflict? In the described scenario,
Wicket is really difficult to use, and that is because one has to be
so careful about domain objects leaking into the session.

Many thanks

Bernard

initialize them lazily just like the model would

Re: Wicket datepicker disable weekdays

[Leo Erlandsson]

This is certainly possible.

You need to use YUI Calendar Renderers. They are documented in the YUI Cal2
API Doc. You can find an example of what you are trying to achieve here
(thanks Google):

http://www.stephaniebender.de/extras/yui/examples/calendar/render/1.html

Basically, you'll want to do this for all disallowed weekdays:

var myCustomRenderer = function(workingDate, cell) { 
cell.innerHTML = "X"; 
YAHOO.util.Dom.addClass(cell, "disallowed"); 
return YAHOO.widget.Calendar.STOP_RENDER; 
} 
YAHOO.example.calendar.cal1.addWeekdayRenderer(1, myCustomRenderer);

This will put an X on all Sundays, making them disabled. Also, it will add a
CSS class ('disallowed') that can be customized if you want to change the
appearance of disabled cells.

Generating standards compliant responses

[Loritsch, Berin C.]

I've set up in my SiteTemplate base class a call to set the content type
for the response, however it is not making it to the browser.  Any
ideas?  When I inspect the request headers and run the site validator
against my page the server content type is set to "text/html" even
though I've told it otherwise.  What am I missing here?  If it helps, it
is hosted in Tomcat 6.  I need the "Content-Type" HTTP response header
to return "application/xhtml+xml"

public class SiteTemplate extends WebPage {
//
public void onBeforeRender() {  

super.getResponse().setContentType("application/xhtml+xml; utf-8");
super.getResponse().setCharacterEncoding("utf-8");

user = IMSSession.get().getUser();

if (null == user && ! (this instanceof LoginPage)) {
this.redirectToInterceptPage(new
LoginPage(null));
}

if (get("content") == null) {
BookmarkablePageLink homeLink = new
BookmarkablePageLink("home",
IMSApplication.get().getHomePage());
homeLink.add(new ContextImage("logo",
"images/logo.png"));
add(homeLink);
add(newUserInfo("userinfo"));
add(newContentPanel("content"));
add(newUserPanel("userbar"));
}

super.onBeforeRender();
}
//  define the newUserInfo, newContentPanel, and newUserPanel
abstract methods
}

Re: strange error

[Martijn Dashorst]

Probably you have a repeater serving out those ajax thingies.

1. Make sure you have a reuse items strategy set
2. Make sure you don't get 2 events right after one another: the link
that is clicked and a seperate behavior you've attached: if one event
updates the repeater, the component is not available anymore.

3. to debug: really look closely at the generated behavior URLs and
look closely at the generated IDs to see if they update to another
value than expected

 The error seems to indicate that the a component is not on the page 
 when it is visible on the page.
 The error is also intermittent.

3rd party js & wicket

[Douglas Ferguson]

Hey,

I added a third party js to my "MainPage" class, which is the base class for 
all my pages (header, footer, etc).

This js has 2 sections. One goes to the top of the body tag and then the other 
at the bottom of the  tag.

Now the requirement has come that I need to add the js to only 1 page.

If I just add it to the sub page, it won't actually be at the very top or very 
bottom of the  tag.

One way to do this is to put it in 2 divs (top and bottom) and show/hide those 
divs based on the page that you are on.

But I am worried that having it divs may not be a good thing.

Is there a way that I could have it dynamically injected into the page?

Yeah.. we have a drop down that updates a repeater. The link is inside the 
repeater.
But I'm not sure why the link is getting messed up.
Also, this only effects XP.

When the hibernate session is closed you will get a lazy initialization error

 Yeah, but how to I guarantee that it will be detached and reloaded on 
 every request.
 
 Also, the application is already using the session as the factory for this 
 loadable detachable.
 Just out of curiosity, I cached it rather than always constructing a new 
 one, and I started getting all sorts of errors.
 
 So then I started to think that perhaps I could try make sure that a new 
 one is generated per request.
 I tried using a thread local to hold the LDM on the session but that 
 caused the same errors.

Validating markup on non bookmarkable pages?

[Loritsch, Berin C.]

I'm using the TotalValidator plugin combined with a local basic
validator installation.  It's a great tool to keep me honest with the
accessibility and standards compliant code.  However certain pages that
aren't linked with a BookmarkableLink can't be validated with the tool.
I end up getting an error like the following:

Nov 20, 2009 3:46:43 PM com.totalvalidator.Validator main
SEVERE: Validation Failed
com.totalvalidator.exceptions.ValidationException: Error retrieving
page: http://localhost:8010/incidents/?wicket:interface=:1 : 404 Not
Found
at com.totalvalidator.utils.FileUtils.getReader(Unknown Source)
at com.totalvalidator.Validator.validate(Unknown Source)
at com.totalvalidator.Validator.main(Unknown Source)


The odd thing is that if I put the same exact URL in my browser the page
renders perfectly fine.  My guess is that because the tool doesn't have
the JSESSIONID cookie and/or has a different browser type that Wicket
expires the page.  Is that correct?  If so, is there any way to work
around it?

If I'm using the redirectToInterceptPage() to get to a login page, is
there a way I can make it bookmarkable?

Re: 3rd party js & wicket

[Igor Vaynberg]

wicket only supports dynamic injection into the  element which
is where all the scripts should go.

as far as your particular usecase you can simple put the script into
wicket:container tags instead of div tags, wicket:container tags
render into nothing.

xmlhttp to another domain

[Ed _]

Hi,

I have an application A that needs to make a call via the browser and not the 
backend to a go  across an internal subdomain applicationB to get the status of 
a user and update the session of the main application A.

Is there a way to add xmlhttpRequest from a panel on the page rendered by A to 
application B and feed the into the  session of application A.


thanks!

Re: Transaction error dont reach onRuntimeException(Page page, RuntimeException e) method

[Igor Vaynberg]

hrm, throwing an exception from onendrequest may be too late for it to
be picked up by onruntimeexception, you may have to do that yourself.

[1.4.3] RequestUtils.toAbsolutePath("") skips the last value

[smallufo]

The code is following :

WebApplication :
mountBookmarkablePage("/TestPage" , TestPage.class);

TestPage.html :
url = 

TestPage.java :
final String url = RequestUtils.toAbsolutePath("");
add(new Label("url" , Model.of(url)));

If I open
http://foobar:8080/quickstart/app/TestPage
it shows  http://foobar:8080/quickstart/app/TestPage  , correct

if I open http://foobar:8080/quickstart/app/TestPage/a/b/
it shows : http://foobar:8080/quickstart/app/TestPage/a/b/ , correct

BUT ,
if I open http://foobar:8080/quickstart/app/TestPage/a/b
it shows : http://foobar:8080/quickstart/app/TestPage/a , WRONG

Ok. I investigated and we are sub classes DataView, so we should inherit the 
default reuse strategy.
Which is DefaultItemReuseStrategy

Do I still have to explicit set it?

It is still odd to me that this only happens in XP?!

 I.E. A component is visible in the screen but when clicked wicket barfs.

Re: request scoped variables

In my opinnion it's a design flaw if you lazy-load suff that you keep
in session. Stop that.

 It seems you have a problem elsewhere? Maybe you have problems with
 object equalities etc?

 YOu can override MySession.detach to detach it.

 whats the usecase for a request-scoped variable?

 you can have a transient field on the page that you null in 
 ondetach()...

 otherwise you can access httpservletrequest and use attributes.
