Re: Regression: @Inject'ed objects cannot be passed to Threads

2010-06-04 Thread Douglas Ferguson
That makes sense. I was just surprised to see it stop working.

It is something people should be aware of when upgrading.

Any idea of what changed from 1.4.5 - 1.4.7 that was have exacerbated this?

Also, what every happened to wrap idea that was proposed?

 you need to make sure the Application object is bound to the thread
 that is executing the runnable, so you will have to pass the
 application along with the dependencies and call application.set/unset
 around the runnable.

 Prior to the upgrade we had some runnables that would do some asynchronous

 This worked fine until the upgrade to 1.4.7. Now when the thread calls

Question about usage of PageMap

2010-06-04 Thread Swanthe Lindgren

Hello all.
I our application we have a lot of search and maintenance pages for 
different type of entities. On each of these pages we put an Add 
button, which takes the user to a wizard to add a new entity of that 
type. In the wizard, we want to be able to send the user back to where 
it came from if the Cancel button is pressed.


Questions:
Is there a simple way to know how the user entered the wizard?
Is this where the PageMap comes in, or is there any other way to track 
the users path in the application?

Image subclass not getting its model object

2010-06-04 Thread Erwin Bolwidt

Hi,

I'm trying to make an image subclass that shows an icon. Which icon it 
shows depends on its model object, which is a boolean. Problem is,  I'm 
not getting the model object: it's always null. If I use a Label instead 
of InStockIconImage, it works: the label shows a boolean (true/false).


Any idea what could cause this?

Thanks,
  Erwin


Here's the icon:

public class InStockIconImage extends Image {
private static final String PATH_IN_STOCK = in_stock.png;
private static final String PATH_NOT_IN_STOCK = not_in_stock.png;
private static final String PATH_NO_MODEL_OBJECT = empty.png;

public InStockIconImage(String id, IModelBoolean model) {
super(id, model);
}

@Override
protected ResourceReference getImageResourceReference() {
Boolean inStock = (Boolean) getDefaultModelObject();
String path;
if (inStock == null) {
path = PATH_NO_MODEL_OBJECT;
} else if (inStock) {
path = PATH_IN_STOCK;
} else {
path = PATH_NOT_IN_STOCK;
}
return new ResourceReference(Icons.class, path);
}
}

Here's how I use it:

RefreshingListViewProductListing listingRepeater = new 
RefreshingListViewProductListing(
listing, new 
PropertyModelSetProductListing(getModel(), listings)) {

@Override
protected void populateItem(ItemProductListing item) {
item.add(new Label(webShop.name));
item.add(new Label(price));
item.add(new InStockIconImage(inStock));
}
};
add(listingRepeater);

RefreshingListView is a utility class which decorates a normal 
RefreshingView:


public abstract class RefreshingListViewT extends RefreshingViewT {

public RefreshingListView(String id) {
super(id);
}

public RefreshingListView(String id, IModel? extends 
CollectionT model) {

super(id, model);
}

@Override
protected IteratorIModelT getItemModels() {
CollectionT modelObject = getModelObject();
if (modelObject == null) {
modelObject = new ArrayListT();
}
return new ModelIteratorAdapterT(modelObject.iterator()) {
@Override
protected IModelT model(T object) {
return new CompoundPropertyModelT(object);
}
};
}

public CollectionT getModelObject() {
return getModel().getObject();
}

@SuppressWarnings(unchecked)
public IModelListT getModel() {
return (IModelListT) getDefaultModel();
}

}

Re: Image subclass not getting its model object

2010-06-04 Thread Erwin Bolwidt

Oops, I went a bit too far in pruning non-essential code.

InStockIconImage has a second constructor:

public InStockIconImage(String id) {
super(id);
}

I think it centers around this. If I pass a PropertyModel(listingModel, 
inStock) explicitly to the constructor, it works, but not if I depend 
on the automatic property resolution that works well if I use a Label.


How can I get it to work if I don't want to pass a PropertyModel explicitly?

Re: Image subclass not getting its model object

2010-06-04 Thread Ernesto Reinaldo Barreiro
Maybe this is related to this override on Image class?

@Override
protected IModel? initModel()
{
// Images don't support Compound models. They either have a 
simple
// model, explicitly set, or they use their tag's src or value
// attribute to determine the image.
return null;
}

Thanks for the answer.

However, Mauro put forward some of the issues it raised, the one with 2 
browser windows.


I would add as well that would have to care about the cleanup of this 
stuff, because having it session's scoped would be enough IMHO (if the 
user is editing heavily), it would have to be linked to the action 
completeness.
Then, putting the VO directly in the Session spoils the memory 
consumption, so you would probably, on top of that, want to put it in 
some dedicated datastore.


In the end, I feel it to be quite error prone. Did you try it already ? 
I would welcome some feedback :$

  Have you taken a look to wicket-wizards?
http://www.wicket-library.com/wicket-examples/wizard/
  

not yet ;)

I thought this wizard widget wouldn't spread on multiple pages. I'll 
look closer then :)

in fact, I mainly wonder about the pages' serialization... are there some 
pitfalls to avoid ?



  If you have to track the object's state through several pages,
you'll need a serializable
object, because reloading it using a LDM in every request will throw
away all the changes
made before.
  So, your Foo must implement Serializable, or you could create some
proxy object that
tracks the changes and when the user finish the editing process, apply
the changes to
the real model object.
  

yep, for sure the VO is Serializable.

But is there any dragon lurking there, with some return page de 
serialized instance's references pointing to some other reference that 
the one behind the current model being given around ?



thanks a lot !

Unfortunately theres no setter for the handle option.

RE: drag and drop

2010-06-04 Thread Stefan Lindner
The default value for both is false! The code:

private boolean onDragStartNotificationWanted = false;
/**
 * If set to {...@code true}, the callback-Method {...@link 
#onDragStart(AjaxRequestTarget,SpecialKeys)} 
 * is called when the drag operation starts.
 * @param value {...@code true} or {...@code false}.
 * @return this object
 */
public DraggableBehavior setWantOnDragStartNotification(final boolean 
value) {
onDragStartNotificationWanted = value;
return this;
}

So I can't see any side effect of calling

wantOnDragStartNotification(false);

There must be some other strange situation.

If you use http://wicketpagetest.sourceforge.net, then you can test
it easily like:

   Selenium s = ...;
   assert 
s.getText(wicket=//storyGrid//body//row[2]//item[3]).equals(foo;


In this example you're checking the the 3rd cell in the 2nd row (both
are 0-based).

AW: drag and drop

2010-06-04 Thread Stefan Lindner
Look into the original jQuery docs for draggable and set any options that are 
not implementet now with

setRawOptions(handle: 'h2');

This should do the trick. If you have any suggestion for implementing a

setHandle(???)

method that doesn't simple have a String parameter, please let me know.

No I have a absolutely specific question to jwicket-jquery.

I want to set the handle option on a draggable, to define the tag which is
used to drag the panel. 
e.g. handle: 'h2'

Unfortunately theres no setter for the handle option.


Thank you

RE: drag and drop

2010-06-04 Thread DerBernd

So here is my Example Case
I have several Platzhalter which implement IDroppable and some
FeldKursObjects which implement IDraggable. The FeldKurs Components are 
dragged on Placeholders.

When I define
dragger.setWantOnDragStartNotification(true);
dragger.setWantOnDragStopNotification(true);
there occurs an error like:
WicketMessage: org.apache.wicket.WicketRuntimeException: component

not found on page kursa.wochenplanung.WochenplanungPage[id = 3], listener
interface = [RequestListenerInterface name=IBehaviorListener, method=public
abstract void org.apache.wicket.behavior.IBehaviorListener.onRequest()]


When I set them false or don't even set anything (default) the error doesn't
occur

Heres the code

public class Platzhalter extends Panel implements IDroppable{

...
private final RepeatingView listPanel;

public void onDrop(AjaxRequestTarget target, Component draggedComponent,
SpecialKeys specialKeys) {
this.listPanel.add(draggedComponent);
WochenplanungPage wochenplanungPage =

  // Parent Page of Platzhalter
target.addComponent(wochenplanungPage);
}
}


public class FeldKurs extends Panel implements IDraggable{

this.kurs = kurs;
dragger = new DraggableBehavior();
dragger.setRevert(DraggableBehavior.DragRevertMode.INVALID);
dragger.setDistance(20);
dragger.setOpacity(0.99);

RE: drag and drop

2010-06-04 Thread Stefan Lindner
This is a general Ajax problem. The ajax calls fired by the jQuery handlers 
dragStart/drag/dragEnd are not sychronized with each other. So it may happen 
that the onDrop event of the droppable is fired BEFORE the dragEnd.
In the onDrop method you replace the dragged component wit a new one (redrawing 
your repeaters).
Then, afterwards, the dragStop event occurs and your component no longer exists.
If you really need to watch teh dragStop in addition to the onDrop, you need to 
synchronize your actions. This means you have to wait for the onDrop response 
BEFORE you redraw you components or in othe rwords: move the onDrop code to the 
onDragEnd.

Sorry, but this is a general problem that can't be fixed in jWicket.

Re: How can override calendar formatting at initialization using DatePicker? getAdditionalJavascript not always working...

2010-06-04 Thread rawe

I got the same problem!
Did you solve it already?
If yes, I would be glad to get some help!

I just disabled the weekend days in DatePicker by overriding the method

@Override
protected String getAdditionalJavascript() {

additionalJavascript += ${calendar}.addWeekdayRenderer(1,
${calendar}.renderOutOfBoundsDate);; // disable sundays
additionalJavascript += ${calendar}.addWeekdayRenderer(7,
${calendar}.renderOutOfBoundsDate);; // disable saturdays

return additionalJavascript;
}

It works, but not when displaying the DatePicker first time. Just after I
did some action in it. (e.g. changing the month)

Thank you!

Re: Image subclass not getting its model object

2010-06-04 Thread Erwin Bolwidt

Hi Ernesto,

Just got the 1.4.9 source code and I see what you mean.
But why is it like this?
I copied the whole Image source code to a new class, removed this 
initModel method, and then things work fine if I don't supply a model.


Why would the Image component behave different from the other 
components? This isn't documented in the Javadoc so I didn't expect 
this, but even then, what is the need for making Image work differently 
than others like Label?


I can think of some usecases where it is fine to display in image that 
is derived from some property on a domain object that is accessed with a 
CompoundPropertyModel:


- when you have a Boolean (like here) or Enum-type property and you want 
to change the image depending on its value
- when you have want to dynamically generate an image with some text (on 
top of a template image), the image is much like a label then


I can't disable this initModel behavior in a subclass, since you can't 
call super.super.initModel, so to disable this behavior, I have to copy 
the whole source of the Image class and remove this method.


That seems like waste and you're not benefiting from future 
improvements in the Image class then.

Renderer does not work when datePicker is initially displayed

2010-06-04 Thread rawe

I`m using  a renderer to work with the OutOfBoundsDate,
but it doesn't work when the DatePicker is initially displayed. 
When I do some action in the DatePicker (e.g. change the month) the
OutOfBoundsDate is correctly rendered (here sundays and saturdays are
disabled)

e.g. I disable the weekend days, so I override the method
getAdditionalJavascript():

@Override
protected String getAdditionalJavascript() {
if (additionalJavascript == null)
additionalJavascript = ;

additionalJavascript += ${calendar}.addWeekdayRenderer(1,
${calendar}.renderOutOfBoundsDate);; // disable sundays
additionalJavascript += ${calendar}.addWeekdayRenderer(7,
${calendar}.renderOutOfBoundsDate);; // disable saturdays

return additionalJavascript;
}

Thanks for any help!

[wicketstuff-core] planning a 1.4.9.1 point release next week.

2010-06-04 Thread Michael O'Cleirigh

Hello,

For release I'm doing at work I need to generate a wicketstuff-core 
1.4.9.1 release.


I see that there have been some updates to trunk (1.4.10-SNAPSHOT) so if 
you would like these changes to be included in the this point release 
please back port your changes to the 1.4.9 branch.


I've also just turned on snapshot building (through my Hudson instance) 
for the 1.4.9.1-SNAPSHOT and the 1.4.8.1-SNAPSHOT versions and they are 
being deployed into the oss.sonatype.org snapshot repository.  The 
polling is every 15 minutes (at 0:15:30:45) just like with trunk.


The 1.4.9 wicketstuff-core branch is here: 
https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/branches/wicketstuff-core-1.4.9/


Probably I am going to cut the point release on Thursday or Friday next 
week.


Regards,

Mike

Frustrating behavior ... same browser, same war, same tomcat version - different behavior!!!

2010-06-04 Thread Bryan Montgomery
Hello,
I've been banging my head against the proverbial brick wall for the last
day. I have a fairly large web application which I've been modifying part
of.

Essentially, part of the process generates dynamic web forms based on xml
configuration files. We noticed that on one of our servers when we deployed
the war file that the fields would not hold their values, and as soon as you
tabbed out, the entry would disappear. Taking the same war file and
deploying it to another server the form acts as expected.

This has been tried on both ie 7 and ie 8 with the same results.

Looking at the html on the browser, it is pretty simple. If I save the file
to the local machine and replace the relative links with absolute links I
can't reproduce the errors - although I do get javascript errors. Comparing
the html between the working server and the problematic server, the only
difference is wicket field references.

Comparing the javascript files and ccs files, they are identical. I'm
guessing it has something to do with the onblur in the html below - but why
would it exhibt a different behavior between the servers? I'm not sure why
we're using ajax there as the page doesn't have any ajax / callback features
to it as far as I know.

Is there some other tomcat setting that could be effecting this? Somewhere
else I should look?

Thanks,
Bryan.

TextField that renders a link

2010-06-04 Thread Josh Chappelle
Does anyone know of a TextField component or perhaps a Behavior that can be
added to a TextField that will render a link when the user types a URL into
it?

 

Thanks,

 

Josh

 would it exhibt a different behavior between the servers? I'm not sure why
 we're using ajax there as the page doesn't have any ajax / callback features

 Is there some other tomcat setting that could be effecting this? Somewhere

Re: Frustrating behavior ... same browser, same war, same tomcat version - different behavior!!!

 Essentially, part of the process generates dynamic web forms based on xml
 configuration files. We noticed that on one of our servers when we deployed
 the war file that the fields would not hold their values, and as soon as you
 tabbed out, the entry would disappear. Taking the same war file and
 deploying it to another server the form acts as expected.


If it works on one server, but not the other, and they are configured
the same (meaning same appserver/tomcat version, same jvm, same
user/group/perms, etc.), the first thing I do is clean the appserver
and do a fresh deploy.

For example, say you are deploying to /var/lib/tomcat/webapps/, I
would shutdown both tomcats, remove the exploded directories (e.g.
myapp.war = myapp/ ) and re-deploy the war files to each server.  I
would also clean out tomcat's temp directory (e.g.
/var/cache/tomcat5/temp), then restart them both.

Re: Frustrating behavior ... same browser, same war, same tomcat version - different behavior!!!

Thanks for the ideas. Still no joy.

The behavior is consistent between three different clients, all running
different versions of IE (6,7 and 8).
I was able to use the debugging feature built in to IE 8 to see that the
wicket ajax javascript was gettting called. At some point in that process it
lost the value of the field and it got set to an empty field.

I have the feeling that there is something different with the environment on
this particular server - but I have no idea what at this point.

Re: Can I develop without recompiling/restarting after every change?

2010-06-04 Thread bht
Hi,

My suggestions were meant to be general, and with best I actually
meant in all environments including certified J2EE servers.

Any number of environments (Igor suggested Jetty) may work with or
without these suggestions.

That is because deployment environments may or may not make decisions
on which way to deploy different file types, or depending on
directories they are loaded from. Files in the web directory are quite
obviously candidates for the fastest deployment method.

If the environment thinks that HTML files need to be deployed in the
same way as Java files, which is quite likely if they are stored in
Java packages, then deploy-on-save setups may slow down the
development process of complex applications due to heavy CPU use.

Therefore, fetching markup from the web directory not from the
classpath is clearly superior under some of these conditions.

This would not break the ability of packaging markup of some
components in the classpath because Wicket can handle that at the same
time.

There is no need to squeeze my comments into the frame of your
community consensus. I am perfectly happy if my comments are correct
only for the other 100% of the community that I am targeting.

OT:

If Wicket adds the trivial feature of resolving HTML resource links
differently then finally there will be separation of concerns.
It will be possible to resolve links to resources e.g. css files,
images when loading HTML files from the local file system in the
package structure in the web directory.

And finally one would be able to use markup refactoring that is
available in today's tools. This is cheap stuff and I am perplexed why
it is not happening. Three lines of code - better practice.

See https://issues.apache.org/jira/browse/WICKET-2881

Bernard

Hrm, perhaps you should have qualified your advice: If you're using
NetBeans, then for best performance...

Also, the packaging of markup on the classpath allows you to create
re-usable JARs of components and IMHO is one of the best features of
Wicket. So perhaps the qualification should really be, If you're using
NetBeans, and you're not planning on packaging your Wicket components in
a re-usable JAR, then for best performance...

The way your original post is phrased makes it sound like a best
practice, and it implies the Wicket default to fetch markup from the
classpath is inferior. I don't think this is a consensus among the
community.

 Storing the HTML in the packages has *nothing* to do with requiring

 If your HTML doesn't get reloaded when you change it, then you should
 run Wicket in DEVELOPMENT mode. Also make sure you've configured
 Eclipse to copy all resources (not just .properties files)
 
 The Wicket Quickstart project and using Maven to generate your eclipse
 project files (mvn eclipse:eclipse) will configure everything
 correctly.

  For best performance of redeploys in Wicket, consider storing HTML not

  getResourceSettings().addResourceFolder(wicket);
 
  where wicket matches the url-pattern in your filter-mapping in

  PLease see https://issues.apache.org/jira/browse/WICKET-2881 for some
  background on how to take this one step further.
 
  Additionally, with GlassFish V3, you get session preservation on hot
  deployment of Java classes.
 
  You can enable deploy on save for convenience.
 
  If that is not fast enough, you can run your app in debug mode and hot
  swap classes after save while you are debugging it.
 
  All this comes with the NetBeans IDE. You really don't have to worry

 wicket ajax javascript was gettting called. At some point in that process it
 lost the value of the field and it got set to an empty field.

 I have the feeling that there is something different with the environment on
 this particular server - but I have no idea what at this point.

 If it works on one server, but not the other, and they are configured
 the same (meaning same appserver/tomcat version, same jvm, same
 user/group/perms, etc.), the first thing I do is clean the appserver
 and do a fresh deploy.

 For example, say you are deploying to /var/lib/tomcat/webapps/, I
 would shutdown both tomcats, remove the exploded directories (e.g.
 myapp.war = myapp/ ) and re-deploy the war files to each server.  I
 would also clean out tomcat's temp directory (e.g.
 /var/cache/tomcat5/temp), then restart them both.

How to do a multiple page form?

2010-06-04 Thread David Chang
Hi, I would like to do a multiple page form. For example, I have a two-page 
form. Both pages have a few fields that need validation. The first page has a 
button called Next and the second page has a Previous button and a Submit 
button.

Any pointers or how-to info will be greatly appreciated.

Best and have a great weekend!

-David

Re: Question about usage of PageMap

2010-06-04 Thread Pedro Santos
I believe that passing the page where user click Add as parameter to the
wizard is an simple solution to has an reference to set on the cancel
response.

 Hello all.
 I our application we have a lot of search and maintenance pages for
 different type of entities. On each of these pages we put an Add button,
 which takes the user to a wizard to add a new entity of that type. In the
 wizard, we want to be able to send the user back to where it came from if
 the Cancel button is pressed.

 Questions:
 Is there a simple way to know how the user entered the wizard?
 Is this where the PageMap comes in, or is there any other way to track the
 users path in the application?

Re: TextField that renders a link

2010-06-04 Thread Mauro Ciancio
Hello,

  An option is to create a panel that inside of it has
two components, a textbox and a link. Via ajax
you can update the textbox's model and show the
link if needed.

  I don't know if there is a pre-made component with
that functions, but I've wrapped two components
into a panel and it works pretty good.

Regards.

 Does anyone know of a TextField component or perhaps a Behavior that can be
 added to a TextField that will render a link when the user types a URL into
 it?



 Thanks,



 Josh

Re: SessionStore life cycle in cluster?

2010-06-04 Thread DmitryM

Igor,

Can you please comment on the following couple of points I got?

1. Pulling session from memcached node: I double checked the
recommendation and it looks like fetching session from the memcached node
doesn't take much time (around 200ms at most). But there was a
recommendation about immediate session attributes deserialization after
session replication
(http://apache-wicket.1842946.n4.nabble.com/A-few-clustering-questions-td1863992.html#a1863993).
Do you think it may be a potential issue causing the request processing
delay I experienced?

2. The memcached-session-manager's developer suggested I could try to use
plain HttpSessionStore (instead of default SecondLevelCacheSessionStore).
But when I tried his suggestion I got the following stacktrace:
