Login page hangs after custom page-expired error page

[Scott Reed]

A created my own PageExpiredErrorPage. There is a button that is 
supposed to take the user to the login page so they can log in (similar 
to the button on the default page-expired error page). /

/
When the user first opens the web site, they see a log in page with URL
/http://mydomain.com/rems/wicket/wicket/bookmarkable/com.mni.SignInPage?1/. 



*Default PageExpiredErrorPage behavior*
After there is a page timeout and the /default /page-expired error page 
opens, the "Return to home page" button on the default page expired 
error page reports URL /

http://mydomain.com/rems/wicket//.

When the user selects that button they go to the login page with address /

http://mydomain.com/rems/wicket/wicket/bookmarkable/com.mni.SignInPage?0

/*and it goes to the home page as expected/desired when the user logs in.*/

/*My custom page-expired error page behavior*/
/After there is a page timeout and the /custom /page-expired error page 
opens, the "Return to home page" button on the default page expired 
error page reports URL /

//http://mydomain.com/rems/wicket//

When the user selects that button they go to the login page with address
/
http://mydomain.com/rems/wicket/wicket/bookmarkable/com.mni.REMSPageExpiredPage#../.. 


/*and it hangs when the user logs in*/./

*custom page-expired error page HTML
*

   
   The page you requested has expired.
   Return to home page
   

*
Java:
*

   public class MyPageExpiredPage extends WebPage
   {
  public MyPageExpiredPage()
  {
super();

// link for home page btn
// WebPage#homePageLink returns a BookmarkablePageLink
add( homePageLink("homeLink"));
  }
   }

I would very much appreciate any assistance with this.

Re: nested table

[Pedro Santos]

Hi, you can nestle repeater components like:
new ListView("id", listOfClass2){
   onPopulate( item){
  item.add( ... );
  item.add(new ListView("id", listOfClass1OfThisClass2){
  onPopulate( innerItem ){
innerItem.add( ... );
  }
  });
  }
}

Problem with Android and ajax?

[PALMER, THOMAS C (ATTCORP)]

We have a problem with a mobile site on an Android.  Basically, we're updating 
select options via ajax with one option that should be selected after the 
update completes.  On an iPhone this works fine and the selected option shows 
in the list as selected.  On Android we get nothing in the dropdown at all 
until the page is refreshed (reloading the complete state).

The Android user agent we're seeing ("Mozilla/5.0 (Linux; U; Android 
2.1-update1; en-us; HTC-A6366/1.0 Build/ERE27) AppleWebKit/530.17 (KHTML, like 
Gecko) Version/4.0 Mobile Safari/530.17") will be treated as Safari based on 
the browser recognition code in wicket-event.js.  It appears the code in 
wicket-ajax.js in Wicket.replaceOuterHtmlSafari isn't doing the right thing for 
Android, despite them both being Webkit based.

Any thoughts on a way to address this?  This is wicket 1.4.14.

nested table

[preben]

Hi 

My wicket experience is quit rusty so forgive me if this is a simple
question, but I have not been able to find any example of this. 

I want to render at table with a nested table in one of the cells. 

eg. 



MyClass1 
   String attribute1; 
   String attribute2; 

MyClass2 
   String attribute1 
   String attribute2 
   List listOfMyClass1 


MyListToRender = List


How would i render MyListToRender using repeaters with a nested List ? 
Any example would be helpfull. 

Thanks.

Re: wicket include in test

Igor,

thanks a lot!

I was thinking of putting some check whether it's a test code into 
production code, but that idea seems a bit whacky :)


Will play with MockServletRequest...

thanks again

what you have to do is trick it into constructing a url that looks

you have to play around with setters on mockservletrequest and looking
at the source of Include component to see how it uses them.

if you cannot get it to do what you want then this component may not
work in the test environment. as the last resort you can toggle its

Re: Problem with setCacheable(false) (No-Cache Header in WebResource)

[eugenebalt]

Hi Angel, thanks for the reply. 

But it looks like this is not making it non-cacheable. It is cacheable, I
get the Excel prompt about reading the local file.

My new code with your suggestion:
--

WebResource export = new WebResource() 
{
@Override
public IResourceStream getResourceStream() {
ByteArrayResource bar = new 
ByteArrayResource("application/vnd.ms-excel",
createExcelBytes());
return bar.getResourceStream();
}

@Override
protected void setHeaders(WebResponse response) {
super.setHeaders(response);
response.setAttachmentHeader("report.xls");
*response.setHeader("Cache-Control", "private"); *
}
};
// COMMENTED OUT setCacheable(false)
//export.setCacheable(false);

ResourceLink exportLink = new ResourceLink("exportLink", export);

Hi,

 

I have a AjaxSubmitLink in a form with an AjaxFormSubmitIndicator behavior

In the method onSubmit of my AjaxFormSubmitIndicator I save my data from

Re: Ajax-refreshing parent page from modal window with Page content

[lunchbox]

Alright,

It worked for me using nested Panel-based modal windows. I had a problem
with nested forms inside the modal windows, and one of these forms required
setting it multipart. Also, I needed to move the modal window divs inside
the forms for all nested modal windows and forms.

Hopefully this will help someone :)

Again, thanks for pointing me in the right direction Martin!

Thanks,

Re: FeedbackPanel rendering

I've made a quickstart project trying to reproduce your code, but I 
didn't get your problem.

The project is based on 1.4.18 and has just one homepage.

Markup code:

xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd"; 
>


Wicket Quickstart Archetype Homepage

















Java code:


public class HomePage extends WebPage {

private static final long serialVersionUID = 1L;
private FeedbackPanel feedbackPanel;

public HomePage(final PageParameters parameters) {
WebMarkupContainer panel1 = new WebMarkupContainer("panel1");
WebMarkupContainer panel2 = new WebMarkupContainer("panel2");

Form form = new Form("form");
form.setOutputMarkupId(true);

AjaxButton subBut = new AjaxButton("subBut") {
@Override
protected void onError(AjaxRequestTarget target, 
Form form) {
target.addComponent(feedbackPanel); // it renders, 
no problem

target.addComponent(form);
}

@Override
protected void onSubmit(AjaxRequestTarget target, 
Form form) {

info("Saved"); // just an info message
target.addComponent(form);
target.addComponent(feedbackPanel); // no way

}
};

panel1.add(form);
form.add(subBut);

panel2.add(feedbackPanel = new FeedbackPanel("feedBack"));
feedbackPanel.setOutputMarkupId(true);
add(panel1);
add(panel2);
}
}


Hi Andre; Thanks for your answer.


I didn't override form's onSubmit method.

Hi,

try here https://cwiki.apache.org/WICKET/migration-to-wicket-15.html

I remember from a few years ago that 1.5 is going to be a non trivial change in

That would be while 1.5 is in development. Now that we are near 1.5
final, migration will be advised as we will start development for 1.6
soonish say when 1.5.1 or 1.5.2 is out, and then stop active 1.4
support (we can only actively support so many versions).

Re: DOUBT & Questions Abt Wicket

[Andrea Del Bene]

Hi Shunmuga,

based on my experience:

1) What are the advantages of wicket over Struts, Springs, Tapestry,
Stripes?

2) What is the main advantages of Wicket?
The frameworks you have listed are based on MVC frameworks. Wicket is a 
component oriented framework, like GWT or Vaadin.
This kind of frameworks  are pretty similar to desktop GUI frameworks 
like Swing, meaning that they and offer an object oriented abstraction 
of web entities like pages, forms, input components and so on.  The 
difference between Wicket and MVC frameworks is well explained here:


https://cwiki.apache.org/WICKET/#Index-AboutWicket


3) Where the wicket can be used in real time scenario?



4) For which database it suits gud?
Wicket is database-agnostic. You can integrate it with your favorite ORM 
o JDBC framework.



5) Which framework is best on performance view?

6) Why wicket has to be used?

Wicket is ideal for pages with a complex behavior ( usually pages with 
some AJAX) and when you have to manage a lot of user data



Now i'm developing a web application project for feeding data&  generating
report for it. For feeding data, i have to give login for every users.
according  a scenario at a time multiple concurrent users ll feed data. For
this which java technology ll be more effective, powerful, efficient? which
framework s best for this?

another scenario is i have to ensure that one user can login at only one
system, he should login at another system on the same time. tat is one user
can have one sessin at one system at a time. he can login to another to
another system at a same time if he tries means an error should be thrown.
for this vat i've to do? can u offer some sample code?

Where EJB can be used? What is the difference in using EJB over frameworks
like Struts, Spring, Wicket, Tapestry, Stripes? Is it possible to use
frameworks with EJB?


Yes, you can use these framework with EJB specification. Obviously if 
you use Spring you are likely to use the whole framework instead of EJB

5) Which framework is best on performance view?

6) Why wicket has to be used?


Wicket

Now i'm developing a web application project for feeding data&  generating
report for it. For feeding data, i have to give login for every users.
according  a scenario at a time multiple concurrent users ll feed data. For
this which java technology ll be more effective, powerful, efficient? which
framework s best for this?

another scenario is i have to ensure that one user can login at only one
system, he should login at another system on the same time. tat is one user
can have one sessin at one system at a time. he can login to another to
another system at a same time if he tries means an error should be thrown.
for this vat i've to do? can u offer some sample code?

Where EJB can be used? What is the difference in using EJB over frameworks
like Struts, Spring, Wicket, Tapestry, Stripes? Is it possible to use
frameworks with EJB?

Re: FeedbackPanel rendering

[Andrea Del Bene]

Hi Lurtz,

what does your form do in its onSubmit method? Have you overriden it?

Hi all;


I have two panels.


Panel one have the standart form with one Label + TextField (required field) + 
AjaxButton.

Panel two have one FeedbackPanel.


Ok, here is the the problem :


I can reach Panel Two' FeedbackPanel from Panel One.


So in AjaxButton


AjaxButton submit = new AjaxButton("submit") {
 @Override
 protected void onError(AjaxRequestTarget target, Form  
form) {
 FeedbackPanel feedbackPanel = getFeedbackPanel(); // gets 
FeedBackPanel from Panel Two
 target.addComponent(feedbackPanel); // it renders, no 
problem
 target.addComponent(form);
 }

 @Override
 protected void onSubmit(AjaxRequestTarget target, Form  
form) {
 FeedbackPanel feedbackPanel = getFeedbackPanel(); // gets 
FeedBackPanel from Panel Two
info("Saved"); // just an info message
 target.addComponent(form);
 target.addComponent(feedbackPanel); // no way
  
 }

 };
When Validation error occurs (onError)  Panel's two FeedbackPanel renders and 
shows the error. Great !


But when there is no error (onSubmit)Panel's two FeedbackPanel doesn't render 
and it gives


component-targetted feedback message was left unrendered. This could be because you are 
missing a FeedbackPanel on the page.  Message: [FeedbackMessage message = 
"Saved", reporter = go, level = INFO]


Any suggestions ?

Regards.

Re: DOUBT & Questions Abt Wicket

[Martin Grigorov]

there are no precise answers to these questions.
for some apps Wicket is better, for other it is not

better search in mail archives and StackOverflow

it depends on the use case

you have to decide whether you like it or not. if you are more
productive with another technology/framework then use it

Yes. Better read more what is EJB and then you'll see that there is no
overlap between Wicket and EJB.

it depends on many factors but mostly on your own code

DOUBT & Questions Abt Wicket

[Shunmuga Raj]

Hi All,

  I was a beginner to wicket. I have some doubts and questions
abt wicket.

Questions:
1) What are the advantages of wicket over Struts, Springs, Tapestry,
Stripes?

2) What is the main advantages of Wicket?

3) Where the wicket can be used in real time scenario?

4) For which database it suits gud?

5) Which framework is best on performance view?

6) Why wicket has to be used?

Doubts:

Now i'm developing a web application project for feeding data & generating
report for it. For feeding data, i have to give login for every users.
according  a scenario at a time multiple concurrent users ll feed data. For
this which java technology ll be more effective, powerful, efficient? which
framework s best for this?

another scenario is i have to ensure that one user can login at only one
system, he should login at another system on the same time. tat is one user
can have one sessin at one system at a time. he can login to another to
another system at a same time if he tries means an error should be thrown.
for this vat i've to do? can u offer some sample code?

Where EJB can be used? What is the difference in using EJB over frameworks
like Struts, Spring, Wicket, Tapestry, Stripes? Is it possible to use
frameworks with EJB?

which one ll be more faster in execution?
