no you dont need the threadlocal
WebRequestCycle is already a thread local thats only used for one request
so in your WebRequestCycle you can have a start time. (onBeginRequest)
and then in onEndRequest you do your calculation.

The problem that i see is that that time covers 2 things. 1 the request
phase on the page of the component that is clicked on
and the response page that could be again that same page but could also be a
completely different one.
So at that time you are testing 2 pages

 Hi thanks for the replies,

 Yes I want to do it per Page so I can monitor the performance per page.

 Here is how I implemented it, I am not sure if I always get the name
 of the Page name in the implementation of onEndRequest. (Allthough
 during tests I always got the name of the Page.)

 public class JAMonMonitoredWebRequestCycle extends WebRequestCycle {

static final String UNIT = ms.;

private ThreadLocalLong startTimes = new ThreadLocalLong();

public JAMonMonitoredWebRequestCycle(WebApplication application,
 WebRequest request, Response response) {
super(application, request, response);
}

@Override
protected void onBeginRequest() {
super.onBeginRequest();
addStartTimeToThreadLocal();
}

@Override
protected void onEndRequest() {
super.onEndRequest();
calculateDurationAndAddToMonitor();
}


private void addStartTimeToThreadLocal() {
startTimes.set(System.currentTimeMillis());
}

private void calculateDurationAndAddToMonitor() {
if(startTimes.get() != null) {
Class? pageClass = null;
if(getWebResponse().isAjax()  getWebRequest().getPage() !=
 null) {
pageClass = getWebRequest().getPage().getClass();
} else {
pageClass = getResponsePageClass();
}
if(pageClass != null) {
MonitorFactory.add(pageClass.toString(), UNIT,
 System.currentTimeMillis() - startTimes.get().doubleValue());
}
startTimes.set(null);
}
}

 }


 I believe the Page to be rendered is not availble yet in the
 onBeginRequest so I use MonitorFactory.add() in the onEndRequest and
 store the startTime in a ThreadLocal. While typing this email I am
 thinking that WebRequestCycle is statefull so I probably do need the
 ThreadLocal right?

Agreed. Here's a model that I use to solve the same problem:

public class BitmappedFlagModel implements IModel {

private IModel bitmapModel;
private int mask;

public BitmappedFlagModel(IModel bitmapModel, int mask) {
this.bitmapModel = bitmapModel;
this.mask = mask;
}

public Object getObject() {
return (getBitmap()  mask)  0;
}

public void setObject(Object object) {

int bitmap = getBitmap();

boolean b = ((Boolean) object).booleanValue();
if (b) {
bitmap |= mask;
} else {
bitmap = ~mask;
}

bitmapModel.setObject(bitmap);

}

public void detach() {
bitmapModel.detach();
}

private int getBitmap() {
return ((Integer) bitmapModel.getObject()).intValue();
}
}

Note that you can still use the CompoundPropertyModel for other
properties:

Form myForm = new Form(myForm, new CompoundPropertyModel(pojo));

myForm.add(new TextField(name));
myForm.add(new CheckBox(enabled,
  new BitmappedFlagModel(
new PropertyModel(pojo, flags), FLAG_ENABLED)));

yes in situation 2 you are testing page2 completely, so the request phase
(handling of the click event)
and the response phase (the render of page2)

but in situation 1 you are testing the request phase of page1 (the click
event)
and then the rendering of pag2 (thats the respond)

And it all depends what takes a lot of time, is it the render because loads
of new data is queried from the db
with loads of stuff on the page. Or is it the action that does a heavy query
or other backend action?

 Hello,

 in the iterator method (see below) I was able to sort on the street column.

 Is this the best way to sort columns?  I am using wicket 1.3.

it might be better to use that sorting info to get the data from the db in the

Normally the modal dialog is only shown by an ajax link.
I guess you show it on onload event. Then yes the page will first load

then call onload and then the modal window will show itself

Re: Pagemap null is still locked by blah exception, help!! why does wicket have to lock the pagemap

2008-01-31 Thread Erik van Oosten

Ah, the wonders of Weblogic.

My first Wicket app runs on Weblogic. A big problem was that the
datasource connection fell away after some time of inactivity. We solved
it by letting Weblogic run a test query every x minutes. We also ran
into very long lasting queries. Where database optimizations didn't
help, we solved that by simply not allowing complex queries.

Anyway, you should never let the pagelock expire. Wicket 1.2.* blows up
on you. I guess this is still the case.

Regards,
 Erik.

TreeTable icons and customization

2008-01-31 Thread Juan Gabriel Arias

Hi all
i've found several threads about this subject, but none of them really
helped me with the issue i'm dealing rigth now...
I want to customize icons for the TreeTable, but i need to put images in a
specific path and i would prefer not to hard code image names.
So, question is:

How can i reference an image with an specific path, _different_ from
container-class package?
My class is com.foo.LabelIconPanel and my image is in
/images/icons/bla.gif

I've looking in ResourceReference (the object used by LinkIconPanel) but i
cant find a way to do this.

About hard-code or not hard-code, i already solve a similar problem putting
special/custom wicket tags in html. And, for example, to set alternate
styles to different rows ina  table, i wrote

table
  tr wicket:id=myTable wicket:rowStyle=rowStyle
wicket:alternateStyle=rowAlternateStyle
td.../td
  /tr
/table

Then, in MyTable.java, i access the attributes with
getMarkupAttributes().get(wicket:rowStyle)

What do you think?

Thanks in advance!
Juan

you can override LabelIconPanel#newImageComponent and create a
WebMarkupContainer instead of an ImageContainer.
on the WebMarkupContainer override onComponentTag and set the src
attribute to where your image is.

log4j and commons.digester on tomcat

2008-01-31 Thread Alex Jacoby

Eclipse crashed, and afterwards I seem to be unable to deploy my  
wicket app on tomcat.  During deployment the digester component  
complains about not being able to find its logger, and my application  
SummerProgram fails to start.


The other deployed apps (non-wicket) seem ok.

I've spent the past hour searching google and the mailing list  
archives.  It seems to come up with tomcat occasionally, but the only  
suggestions have been to make sure that the log4j jar isn't in the  
tomcat shared/lib or common/lib directory, and in my case it's not.


Any ideas?

Alex

Re: HybridURLCodingStrategies vs others

2008-01-31 Thread mfs


Thanks for the follow up Matej, it does clarify certain things..but
commenting on your last point, as you said earlier..the links/buttons (bind
to any event) have the pageId in them irrespective of whether the page is
loaded through BUCS or HUCS, so even in case of BUCS we still would have the
pageId on an event-invocation, so why cant the page (in session be retrieved
based on the pageId with those links) and be forward to..

 No. The pageId in url is of course used to retrieve page instance from
 session which is then tested to match the mount point.


 - So other strategies are there to provide relatively clean-er url ?
 (i.e.
 without pageId and version info) what other reasons would be there to use
 the non-HUCS, i wonder what happens to existing the page instances ?
 Nothing new page instance is created, that doesn't affect the old page
 instances at all.

 - Creating a new page-instance for every call, doesnt that break the back
 button support ? arent we compromising the wicket functionality of
 maintaining page-history by creating a new page instance every time and
 not
 using the existing ones ?
 What do you mean by every call? New page instance is created on
 every request with regular bookmarkable URL. That doesn't affect back
 button at all becaue all page instance relative urls (listener
 interface, e.g. clicking a link on page) are not bookmarkable and
 contain the page instance id. Only when you refresh the page (while
 still having the bookmarkable url in url bar) new page instance is
 created.

 - Last but not the least when i read that all other strategies other than
 HUCS doesnt preserve the mount path after a listener is invoked on that
 page
 sounded like a bug to me, i mean why cant the mount path be preserved
 using
 the same strategy ?, with that a person is bound to use HUCS although he
 prefers to keep to BookMarkableUCS since its more clean in terms of
 displayed url.
 That's the point. The regular URL conding strategies don't insert page
 instance in URL. So after clicking a link there is no way to redirect
 to bookmarkable URL while still displaying the same page. That's the
 whole reason for hybridurlcodingstrategy.

Re: log4j and commons.digester on tomcat

2008-01-31 Thread Alex Jacoby

Well, solved it at last.  Finally looked in my output directory and  
saw that it was totally empty.  That was the real problem -- no class  
files -- but the lack of tomcat logging (or selective logging to  
system.out) hid that well.


Clean build didn't help.  Replacing eclipse config files with older  
versions from CVS didn't help.  Trashing my ~/.eclipse didn't help.   
Still no class files were generated by eclipse.


Changing the output directory and then changing it back finally  
resolved it.

Re: How to delete an item from List view.


Hi igor,

But If I remove setReuseItems(true), it'll remove all field values which
user has entered will be removed.
Bcz default processing  is false for Remove button (Sorry forget to tell
you)
I just want to remove vehicle2, but the values entered for vehicle1 
vehicle3 should not be lost.

Re: Article: Introducing Apache Wicket

2008-01-31 Thread Sam Barnum


Question on detachable models:

You use detachable models in the contact edit page.  It seems like  
this would cause your changes to be lost if the edit process takes  
more than one request to complete.


If you use the no-arg constructor, the loadableDetachableModel  
creates a new contact at the beginning of every request.  If you  
enter a name that's too long, a validation message is displayed. Then  
the detach() is called on the model, and a new Contact is loaded on  
the next request, erasing your temporary changes.


I may well be misunderstanding something, I'm fairly new to this  
stuff.  It seems that for edit pages you want a non-detachable model,  
which gets serialized to the session.


Thanks for taking the time to write this article, and thanks in  
advance for any clarification on this topic.

Re: Article: Introducing Apache Wicket

if there is a form error then the changes are never applied to the
pojo in the first place. wicket's form workflow is atomic - the model
object is ever updated when all required,type conversion,validation
was successful on all form components in the form. if something failed
wicket will keep the input and display it again when the form is
rerendered.

makes sense?

Re: is there wicket had per-defined the Thread for the form component

2008-01-31 Thread kenixwong


thanks for reply, johan

i want to show the modal window once the report page is load. Mean
background is continue loading the report and the modal window is just as a
control (its features is invisible the background and only close once action
performed is click in the modal window ) to prevent user navigate to other
page. For the modal window it only define one cancel button, mean if user
click the cancel button, the background ( report page ) is stop. 

Yes... the modal window is only shown by an ajax link. I get the source from
this forum ..where it can fire the ajaxlink whitout click the link. Here is
the code

 getBodyContainer().addOnLoadModifier(new ClickOnceOnLoadModel(
ajaxLink ), null );

Even i tried to create a modal window with ajaxlink ( add auto fire event as
above code ) and put at the parent class and the report page is the child
class. But the result is same, the report page is finish loaded then only
pop up the modal window.

my report page constructor :

public LineChart() {
/// modal window use panel..declare the modal window setting here then
add
 add(modalWindow);

 // to auto pop up the modal window.
 ajaxLink = new AjaxLink(cancelReportModalLink){
@Override
public void onClick(AjaxRequestTarget target) {
cancelReportModal.show(target);
}
};
 add(ajaxLink);

  //  Fire the ajaxLink onclick function
 getBodyContainer().addOnLoadModifier(new ClickOnceOnLoadModel( ajaxLink
), null );
 
 add(feedback);
 add(new LineChartForm(LineChartForm));
}


private class LineChartForm extends Form {
// execute query
// result as in JFreeChart
} 


i add the component for modal window then only come to form. supposedly it
will show the modal window then load the form, am i right . Why ? 2 process
in a same time cant together?  Is because the process haven't done, so the
request wont send to wicket there, 

2 way i tried. Call the modal window at Parent class and also child class.
But it still given me the same result.

between, can you explain more or give example for the onload event that you
mentioned ? onLoad event for the modal window ? I was using the wicket
1.2.4. Is it the version cant support it and i need to upgrade ?



Thanks in advance

Johan Compagner wrote:
 
 how do you show the modal dialog??
 Normally the modal dialog is only shown by an ajax link.
 I guess you show it on onload event. Then yes the page will first load
 itself
 then call onload and then the modal window will show itself

if you want to talk about a cleaner way...

add(new removelink(remove, item.getmodel()) {

assuming vehicles is a property on listview's parent...

Notifying a DataTable that data has changed

2008-01-31 Thread jwray


Hi,

New to Wicket so this maybe some obvious I'm missing and I'd appreciate any
pointers.

I have an AjaxFallbackDefaultDataTable within a AjaxTabbedPanel backed by a
SortableDataProvider that drags data from a database as needed. One column
of my table contains an AjaxFallbackLink. This link opens up a ModelWindow
by constructing a Panel with the object from the selected row of the table
and setting the model window content before showing the window. The panel in
the model window contains a form for editing properties of the passed in
object, with two AjaxButtons for OK and Close. OK will take the form model
object and persist it to the database. All this works great, but I can't see
a way of notifying the table, or underlying data provider, that the data has
changed and needs to be refreshed. Any pointers on either how to do this or
an alternative approach?

thanks in advance.
Jonny
PS. This is my first attempt at using wicket and it's been refreshingly easy
to get this far. Thanks for a great framework.

Re: Notifying a DataTable that data has changed

can you not add an onclose callback to the window that repaints the
datatable by adding it to the ajax request target?

Hi,

New to Wicket so this maybe some obvious I'm missing and I'd appreciate any
pointers.

I have an AjaxFallbackDefaultDataTable within a AjaxTabbedPanel backed by a
SortableDataProvider that drags data from a database as needed. One column
of my table contains an AjaxFallbackLink. This link opens up a ModelWindow
by constructing a Panel with the object from the selected row of the table
and setting the model window content before showing the window. The panel in
the model window contains a form for editing properties of the passed in
object, with two AjaxButtons for OK and Close. OK will take the form model
object and persist it to the database. All this works great, but I can't see
a way of notifying the table, or underlying data provider, that the data has
changed and needs to be refreshed. Any pointers on either how to do this or
an alternative approach?

thanks in advance.

PS. This is my first attempt at using wicket and it's been refreshingly easy
to get this far. Thanks for a great framework.

Igor,

thanks for the reply and pointing me in the direction of a call back and the
ajax request target. I've not looked at the request target class in depth
yet, so that's probably the piece I was missing. I'll give it a try
tomorrow.

Challenge: write something really sleek for Facebook?

2008-01-31 Thread Eelco Hillenius

Hi,

Daniel Kaplan wrote a WIKI page[1] that describes how to set up Wicket
for Facebook. Someone posted a link to that on DZone[2], and that in
turn prompted Dave from Alfresco to write an alternative to it that
shows it can be done much shorter[3]. I know that several people
posted the idea before of writing a simple integration framework for
Facebook/ Wicket, but so far no-one actually contributed code (besides
this WIKI).

How about it? Is that blog posting a challenge enough to come up with
a simple framework that makes writing Facebook apps with Wicket short
and elegant? I can imagine we'd need a component (set) and/ or
specialized models for parsing external REST requests. But maybe I'm
just talking crap here. Any takers? :-)

 Hi All,

 I have rendered a list view on a Web Page.

 vehicle1X
 vehicle2X
 vehicle3X

 when a person click on 'X', that item should be deleted.
 But I'm facing an issue, when i click on 'X', last item get deleted.
 Actually when I delete vehicle2 from my list, it deletes vehicle2 but that
 component is still there.
 So while rendering it render vehicle1  vehicle2.

 public void onSubmit() {
 List vehicles = (List) getParent().getParent().getModelObject();
 vehicles.remove(index);
 }

Instead of using ListView, you could consider RefreshingView with it's
itemReuseStrategy set to ReuseIfModelsEqualStrategy.

 Bcz default processing  is false for Remove button (Sorry forget to tell

 I just want to remove vehicle2, but the values entered for vehicle1 
 vehicle3 should not be lost.

2008-01-31 Thread Martijn Dashorst

Could that someone please *not* link directly to the confluence page as is
stated on the front page of the wiki [1]?

This link goes to the same page, but is 100x times faster and puts 100x less
load on the server.
