Hello Igor and Timo,

Sorry for my really way to late response, I was caught up entirely by
some stressful tasks which needed to be finished. 

I currently do not have statistics, but I could have a cpu yourkit
snapshot. I have seen up to 75% cpu in the serialization and
deserialization. Recently I saw 25%.

People working with Linux do not experience this cpu bottleneck though,
so it might very well be an issue with how windows handles the
filesystem. I will sort out the suggestion by Timo, would be great if
that solved the issue. 

Thanks a lot, and again, sorry for my late response!

 While waiting for the reply from Ard... I remember hearing of 
 a case where the pagemaps were stored to a directory that the 
 virus scanner was monitoring, and the scanner hogged all cpu 
 during load testing :) I suppose that this kind of stuff 
 happens more easily on Windows than on unices.
 
 Best wishes,
 Timo

RE: AbstractPageStore memory implementation instead of disk

Hello Matej,

 I'd really be interested in how exactly did you come to 
 conclusion that DiskPageStore writing to disk is the 
 bottleneck. Unless your filesystem caching is broken :) 

Hmmm, don't think the filesystem cache is broken. I am working with
filesystem caches and lucene a lot and don't experience really bad
performance. Through when profiling our wicket application with yourkit,
I happened to see a lot of cpu being absorbed in the serialisation /
deserialisation to filesytem

Regards Ard

 Serialization takes a significant part of request processing, 
 but that is necessary.

2008-10-07 Thread richardwilko


I should say that the terracotta page map also does the page serialisation,
but it does it all in memory.

You could probably write out the serialisation bit quite easily, but it is
required for terracotta.

RE: AbstractPageStore memory implementation instead of disk


 but serialization and writing to disk are 2 different things.

Yes sorry for the confusion. I intertwine the serialization and disk
performance (hence asking whether a memory page store exists) because
AFAIU, it is the serialized pagemaps that are being written to
filesystem. Indeed, when using a memory page store, still serialization
to memory is needed, so you are indeed right to say that they are
different. I should talk about the cpu bottleneck of writing the
serialized pagemaps to disk and whether there is a pagestore using
memory. As indicated by Richard, this one seems to exist in Terracotta.
I will try and see whether this avoids my experienced cpu bottleneck.
Also the virus scanner option I will look into 

By the way, using 

protected ISessionStore newSessionStore()
{
 return new HttpSessionStore(this);
}

Instead of 

protected ISessionStore newSessionStore()
{
return new SecondLevelCacheSessionStore(this, new
DiskPageStore());
}

Also avoids the disk writing bottleneck. Now, I am not sure whether
HttpSessionStore can be used instead of SecondLevelCacheSessionStore. It
does not seem to write to diks.

Thanks for all the pointers and fast responses everybody

RE: AbstractPageStore memory implementation instead of disk

2008-10-07 Thread richardwilko

The HttpSessionStore is an in memory session store, so it has no disk writing
bottleneck. It does however have some other problems, specifically with the
back button i think.

the terracotta page store works like this:

protected ISessionStore newSessionStore()
{
return new SecondLevelCacheSessionStore(this, new
TerracottaPageStore(100));
}

as it is just an implementation of the IPageStore interface as is the
DiskPageStore, but where the DiskPageStore writes to disk the
TerracottaPageStore writes to http session.

The 100 is number of pages to keep in history as far as i remember, check
the source to be sure.

Re: Serializing model. DetachedModel or not

 Hello Edmund.
 Nice to have someone in the same timezone!
 Thanks for your reply. I'll try to set the modelobject member in the LDM to
 transient and see if it solves the serializing exception(even if you don't
 recommend it). Just want to try it out. 
 
 If I understand you correctly you only keep a serialized identifier as a
 member in the subclass of the LDM and then use the load method to populate
 the modelobject. Have you been working with the SortableDataProvider?
 Because I still have not figured out how one should combine the above
 discussed LDM load method with the iterator method in the SDP. Do you call
 the database in the LDM load method to get the data for the model. If so, do
 you also call the database in the SDP.iterator method to get the data
 collection for the current page? Because it seems to me that in that case
 I'm getting the modelobject data twice from the database.
 
 Jens Alenius
  

There should be no need to load the object twice from the DB for one request.
You either fetch it using the SDP (and then construct a new LDM for each object)
or you use the LDM to retrieve a single object (or LDMs for several select
objects).

Either way, I don't know of a case where you would want to fetch the object both
ways for handling one and the same request. So, both the LDM load and the SDP
iterator methods commonly fetch the object(s) from the DB, but you should not
use both of them for handling any one given request (not for the same object, I
mean). You can call the getObject() method of a newly instantiated LDM as many
times as you like during one request without causing it to retrieve the object
from the database, IF you passed that object to its constructor.

Cheers
 Edmund

The WIA book says:

Setting an HTTP status code:
If you want to set an HTTP status code for your page, such as 404 (not 
found), you
can do so by overriding the page's setHeaders method:

@Override
protected void setHeaders(WebResponse response) {
response.getHttpServletResponse().setStatus(
HttpServletResponse.SC_NOT_FOUND);
super.setHeaders(response);
}

Alternatively, you can throw an AbortWithWebErrorCodeException and 
provide it
with the appropriate error code and an optional message.

Interfaces for component hierarchies (e.g. Buttons)?

2008-10-07 Thread Martin Dietze

Hi,

 I am currently running into the following: I extend the button
class by a snappy foo-feature. I build stuff which uses it.
Now I need a foo-ified AjaxButton within this infrastructure.

The obvious way to do this is to write an interface FooButton
which gives me this foo-feature. However FooButton is by
itself not a Button, nor can I make it one since the Button
class is an abstract class, not an interface.

Just wondering, whould it be a good idea to add such interfaces
to the Wicket-API? Or am I missing something?

Cheers,

Martin

Re: Modeless Window (real or div)

2008-10-07 Thread Francisco Diaz Trepat - gmail

right, the nonmodal window is basically a calculator (kind of) that helps
the user do some math. It needs to have access to lower (layer-wise)
fields.
If a modal window is displayed then it should cover the nonmodal window
(lets call it the calculator).

I can do this with some error like this:

new ModalWindow(calculator){ private static final long
serialVersionUID = 0L;

 @Override
 public void show(AjaxRequestTarget cTarget) {
super.show(cTarget);
cTarget.appendJavascript(if
(typeof(Wicket.Window.get())!=\undefined\) {
Wicket.Window.get().destroyMask(); });
 }

  };

This destroyMask works fine, but when I close the window, it throws an error
due to destroyMask is called again and inside executes the following code:

/**
 * Destroys the mask.
 */
destroyMask: function() {
this.mask.hide();
this.mask = null;
}

I am thinking in overriding this body with:

/**
 * Destroys the mask.
 */
destroyMask: function() {
if(this.mask) {
this.mask.hide();
this.mask = null;
}
}

Or something of the sort.

Re: Serializing model. DetachedModel or not

if wicket tries to serialize the object you are trying to hold on to a
reference of it outside the ldm somewhere in your code. eg

object o=ldm.getobject();
add(new label(o, o));

 Thanks Igor
 In my code I started with with a LDM initialized with the modelobject
 itself. But it if the modelobject dont implement serializable I get
 serialize exception for the modelobject(e.g. contact). My assumption is that
 the modelobject is being serialized to the session. I thought that the LDM
 is a model you use when you dont want to serialize the model to the
 session(http://cwiki.apache.org/WICKET/working-with-wicket-models.html#WorkingwithWicketmodels-DetachableModels).
 But in the end,as jwcarman wrote, wicket handles the session with disc
 writing so it probably no problem. But if its so that the LDM is serializing
 the modelobject in session when you initialize the LDM with it, could I not
 just use a basic Model instead?

Closing ModalWindow using javascript:window.close()

2008-10-07 Thread nanotech


Hi,

In my project there is a modal window.In event of WicketRuntimeException it
goes to custom Internal Error page. That Page has a button which overrides
onComponetTag method and  attaches javascript:window.close() with
onclick event. So that user can close the modal window.(I don't want user
to use [X] button in right top corner so I have hidden that button through
CSS). The problem is this [javascript:window.close() ] does not close modal
window but it does work in regaular page.(i.e. if execption occurs on a
regualr page then after the request is forwarded to Custom Internal error
page then user is able to click on close button and the browser window
closes.)

Can some one please suggest me how to achieve this is modal window.

Thanks,
RG

Re: force page reload

2008-10-07 Thread francisco treacy

as it is kind of a workflow and i had all the pages already prepared
by passing imodels along into constructors, i didn't want to have a

this one to call the page executing the code). but this was the

post, get it back and initialize the a detachablemodel again with the
id and the dao.

so i changed a bit my code to fit this no-arg constructor page, which

imo it is a good idea to use variations. a panel could have also been,

 It seems to me a bit strange to use markup variant for this. You could
 have your callback page forward to the correct page like this:

 public CallbackPage(PageParameters params) {
if (params.getString(DATA).equals(good)) {
setResponsePage(PaymentGoodPage.class);
} else {
setResponsePage(TryAgainPage.class);
}
 }

 Alternatively, you could instantiate an appropriate panel in your page:

 public CallbackPage(PageParameters params) {
if (params.getString(DATA).equals(good)) {
add(new PaymentGoodPanel(responsePanel));
} else {
add(new TryAgainPanel(responsePanel));
}
 }

  It seems to me a bit strange to use markup variant for this. You could
  have your callback page forward to the correct page like this:
 
  public CallbackPage(PageParameters params) {
 if (params.getString(DATA).equals(good)) {
 setResponsePage(PaymentGoodPage.class);
 } else {
 setResponsePage(TryAgainPage.class);
 }
  }
 
  Alternatively, you could instantiate an appropriate panel in your page:
 
  public CallbackPage(PageParameters params) {
 if (params.getString(DATA).equals(good)) {
 add(new PaymentGoodPanel(responsePanel));
 } else {
 add(new TryAgainPanel(responsePanel));
 }
  }

Prevent component markup regeneration in ajax call

2008-10-07 Thread Adriano dos Santos Fernandes


Hi!

I'd like to have extjs toolbar/menu working with Wicket ajax. What I 
want is, for example, in an ajax event show/hide menu items. I created 
the classes and the menu is rendered correctly.


My toolbar render everything from its renderHead (IHeaderContributor) 
method. All javascript code is dumped to the response to render the ext 
component to a div.


I looked at wicket-tools-extjs but still can't figure how to do what I 
need. If I re-render (ajax) the component it just hide. I tried 
different readerRead code when it's called by the second time, but the 
previously rendered component just hide too.


So my question is how I could prevent wicket from regenerate the div 
when updating a component added to an AjaxRequestTarget?

Re: Interfaces for component hierarchies (e.g. Buttons)?

Depending on what you are doing, you may want to try implementing the foo
feature code as a behavior.  Behaviors are like plugins for components, and
can be used on any component.  So, if it is possible to implement your
functionality as a behavior, then you could add it to the button or ajax
button, or a link, etc.

 Hi,

  I am currently running into the following: I extend the button

 Now I need a foo-ified AjaxButton within this infrastructure.

 The obvious way to do this is to write an interface FooButton
 which gives me this foo-feature. However FooButton is by
 itself not a Button, nor can I make it one since the Button
 class is an abstract class, not an interface.

 Just wondering, whould it be a good idea to add such interfaces
 to the Wicket-API? Or am I missing something?

Often it's a good idea to start a new thread with a

 I want to change one of  the Contact page form component's visibility

 Is there a page onLoad function or something where I can check the parameter
 value and then change visibility of the component? If yes.. then where is it
 called? Or how? When ever I try to check the parameter value within the page
 constructor, I get a NullPointerException, but when the parameter is used
 for other things , like from a method called within the the Form onSubmit()
 there doesn't seem to be any problems.

Constructor is only called on construction, not rendering. 

You have at least a couple of options;

  FormComponent myComponentWithConditionalVisibility = new TextField(foo) { 
  @Override
  public boolean isVisible() {
  return fooFieldShouldBeBVisible();
  }
  }

or

  FormComponent myComponentWithConditionalVisibility = new TextField(foo) { 
  @Override
  public void onBeforeRender() {
  setVisible(fooFieldShouldBeVisible());
  }
  }

Custom Text Field...

2008-10-07 Thread Steve Thompson

Hi,

I'm attempting to create a custom validator for social security number
strings.  I've got the following code for this:

static Pattern pattern = Pattern.compile((\\d{3})[ \\-]*(\\d{2})[
\\-]*(\\d{4}));

public final IConverterString getConverter(Class type)
{
return new IConverterString()
{

public String convertToObject(String value, Locale 
locale)
{
String result = ;
result = value.substring(0, 3) + - + 
value.substring(3, 5) + -
+ value.substring(5, 8);
return result;
}

public String convertToString(String value, Locale 
locale)
{
String result = ;
Matcher fit = pattern.matcher(value);
if(fit.find())
for(int index = 1; index = fit.groupCount(); index++)
result += fit.group(index);
return result;
}

};
}

When I use this with a text field, I can intercept the calls to
convertToString.  However, convertToObject never seems to be getting
called.  Is there something that I am doing wrong/not understanding?

Thanks and best regards,


Steve

Need some clarification on AjaxBehaviors

2008-10-07 Thread Steve Thompson

I was recently working on creating some Ajax functionality that, when
a record was added/updated/deleted in my form would display some
informational label that would gradually fade away.  While I can get
this to work, I would like to refactor this into some type of reusable
behavior.  Is this possible, and if so, how might it be done?

One approach that I've tried that did not work was adding a custom
AjaxBehavior to the submit (itself an AjaxButton).  I was expecting
that perhaps the behavior could be invoked after the buttons onSubmit
method, but I haven't figured out how to make this happen.  Am I on
the right track?

Any ideas would be greatly appreciated,

Re: Custom Radio component with children?

we do not guarantee the order of updates for sibling components, we
only guarantee that the deepest components are visited first - so you
should not make an assumption about order of evaluation when writing
the code.

it is indeed weird that the FCP is not visited, as far as i can see
the visisitor visits all formcomponents of which FCP is a subclass.

 I have run the page in Tomcat and narrowed down the problem to the following:
 - FCP's convertInput is NOT called only when radio tied to drop down is
 selected.

 I think the problem has something to do with both PublicLocationRadio and
 PublicLocationDropDownChoice sharing the same model (publicLocationModel).
 Here's what is happening (in actual order) during form submit:
 -FormComponent.convertInput() called on Radio Group. at end of method
 'convertedInput' is null (THIS IS BECAUSE SELECTED PublicLocationRadio's
 model object is null)
 -FormComponent.convertInput() called on PublicLocationDropDown. convertInput
 is corrrectly updated to new PublicEventLocation model object
 -FromComponent.convertInput() is NOT called at all. As the matter of fact,
 FCP is NOT visited with ValidationVisitor created inside
 Form.validateComponents()


 So, I clearly made a wrong assumption that DropDownChoice would be evaluated
 before PublicLocationRadio. I thought dropdown would update
 publicLocationModel to own selected value and when RadioGroup's convertValue
 calls publicLocationradio.getModelObject(), publicLocationModel would return
 newly updated model object.

 But I still do not understand why FCP's is not visited in
 Form.validateComponents() or its' convertInput method called.

 my RadioGroup is setRequired(true) and yet, because of the above problem,
 its' convertInput is set to null. Would that be the reason why FCP is not
 visited?

Re: Custom Text Field...

2008-10-07 Thread Steve Thompson

Timo -

Thanks for your response.

I did use a PatternValidator alone in my first approach, but while I
could verify that '123-45-6789' was a legitimate SSN, what I wanted to
additionally do was fill in my model object's string with '123456789'.
 Now, if the setSsn() in the model object needs to incorporate this
behavior, I can live with that, but I thought it would be cleaner to
convert to/from the model using a custom converter.

Here is the full text (sans imports) of the SsnTextField:

public class SsnTextFieldT extends TextFieldT
{
static Pattern pattern = Pattern.compile((\\d{3})[ \\-]*(\\d{2})[
\\-]*(\\d{4}));
public SsnTextField(String id)
{
this(id, null);
}

public SsnTextField(String id, IModelT object)
{
super(id, object);
add(new PatternValidator(pattern));
}

@Override
public final IConverterString getConverter(Class type)
{
return new IConverterString()
{

public String convertToObject(String value, Locale 
locale)
{
String result = ;
result = value.substring(0, 3) + - + 
value.substring(3, 5) + -
+ value.substring(5, 8);
return result;
}

public String convertToString(String value, Locale 
locale)
{
String result = ;
Matcher fit = pattern.matcher(value);
if(fit.find())
for(int index = 1; index = fit.groupCount(); index++)
result += fit.group(index);
return result;
}

};
}

}

 Are you overriding getConverter?

 For custom validation, your better off using validators
 rather than converter for that. Check out the form
 validation examples.

 Basically your approach should work as well, it's just
 weird design to do validation in conversion, especially as
 your IConverter returns Strings and not ready-made
 SocialSecurityNumbers. But we'd need to see more code to be
 able to help debugging it. Make sure that your form
 component gets submitted.

 Thanks Alastair, that's a good idea. AjaxEventBehavior would give the
 effect but with a round trip to the server.  It would be nice to have a
 javascript only onmouseover where the images are pre-loaded.

 I'm currently using the wicketstuff-dojo onmouseover-highlight, which is
 good enough for now.

 Thanks again,

  Have a look at AjaxEventBehavior. You can either combine this with an
  Image
  component or add an AttributeModifier and manually tweak the img's src
  attribute.

  Hi All,
 
  Before I go and write my own component to change the src of an img
  onouseover, I just wanted to make sure that there is no standard
  component.  I don't want to re-invent the wheel.
 
  Is there a standard component for changing the Image or ImageButton
  image
  onmouseover?
 
  Thanks,
  Tim

Way to handle a URL/GET without a Page?

2008-10-07 Thread metalotus


Hi,

Must a URL be handled by a Page object? Is there another option? 

For exmaple, I want to call a URL from browser-side javascript and then on
server-side go through the wicket request cycle, do some work, change some
state, and write to the response. But I am worried about using Page to
handle the URL since I don't want to mess up navigation forward/back, etc.

Is this related to the concept of a stateless page? I'm fuzzy on that.

Thanks, James

Re: Way to handle a URL/GET without a Page?

Typically this would be handled with Ajax behaviors.  They are written for
this purpose.

Submit a form automatically after N seconds

2008-10-07 Thread Edgar Merino

Hello, I've been trying to add this functionality to a component, after 
(say) 120 seconds I want to submit the form automatically (via ajax) in 
order to create a backup of the information hold at that time by the 
component. I've been looking at ajaxformsubmitbehavior but I don't see 
how to make this work with what I need. I think an 
abstractajaxtimerbehavior is what I need here but I need to know how to 
submit the form in the onTimer method.


Thanks in advance.
Edgar Merino
